The recording device location acquiring unit 101 acquires the installation location of the recording device (hereinafter referred to as the recording device installation location). The recordable program list acquisition unit 102 acquires a program list (hereinafter referred to as a recordable program list) of broadcast contents (programs) at the location where the recording device is installed. The browsable program list acquisition unit 103 acquires a program list of broadcast content at the current location (hereinafter referred to as a browsable program list). The identical program judging unit 104 compares the list of programs that can be browsed and the list of programs that can be recorded, and judges the identity of each program. The display unit 105 displays whether or not the currently viewed program can be recorded on the recording device based on the identity of the programs determined by the identical program determination unit 104 .

2 is a configuration diagram showing an example of a hardware configuration used in the viewing support device according to Embodiment 1 of the present invention. The system has: a digital TV 1201, which receives digital broadcast; a hard disk video recorder 1202, which is a video recording device that can store digital broadcast in a hard disk; a home gateway 1203, which connects the network equipment at home to the network outside the home; the electronic program list server 1204, stores electronic program table and can be accessed from external network; mobile phone 1205, can receive and display digital broadcast, and has audio-visual support device 100.

Next, the operation when the user uses the mobile phone 1205 having the viewing support device 100 configured as described above to view a program at a place far from the installation place of the recording device (hard disk recorder 1202) will be described. FIG. 3 is a flowchart showing the flow of operations when the user watches a program on the mobile phone 1205 . Here, it is assumed that, for example, the installation place of the video recording device is Osaka (home, etc.), and the user has gone to Tokyo on a business trip or the like.

First, the browsable program list acquisition unit 103 acquires a browsable program list as a program list at the current position from the received broadcast wave (step S101 ). In addition, the program table is multiplexed and distributed to each area where the mobile phone 1205 is held. Therefore, mobile phone 1205 with a built-in broadcast reception tuner can receive program tables related to programs receivable in each area. In addition, the mobile phone 1205 may also have a GPS function, and by determining the current location, obtain the program table of the area from the electronic program table server 1204 through the network.

Then, the recording device position acquiring unit 101 acquires the installation location of a recording device that can be randomly accessed, such as a hard disk recorder and a DVD recorder (step S102 ). The program received and played by the video recording device is recorded in the storage medium, and the video recording device is generally installed in the user's home or the like. In addition, the place where the video recording device is installed may be set in advance.

The recordable program list acquiring unit 102 accesses the electronic program guide server 1204 via the network, for example, and acquires the recordable program list of the recorder installation location (Osaka) acquired by the recorder location acquirer 101 (step S103).

Then, the same program judging unit 104 judges whether or not the browsable program list and the recordable program list are different (step S104). In addition, in the example of this embodiment, the program schedules to be transmitted are different because the programs of each region are broadcast at the location where the recording device is installed (Osaka) and the location where the user holding the mobile phone 1205 is currently located (Tokyo).

If the judgment result is that the browsable program table and the recordable program table are different (YES in step S104), the same program judging unit 104 judges whether the currently viewed program is also played at the installation location (Osaka) of the recording device (step S105). In addition, it is judged to be played when the time is changed in the future or played one week behind even if it is not played at the same time slot. And, if it has already been played, it is judged not to play.

Here, when the currently viewed program is being played at the installation location (Osaka) of the recording device (YES in step S105), and when the list of programs that can be browsed and the list of programs that can be recorded in the above-mentioned judgment process (step S104) are the same (step S104) No), since the video recording can be recorded at the place where the video recording device is installed, the display unit 105 displays the icon "recording possible" on the screen currently viewed by the portable terminal 1205 (step S106). FIG. 4 is a diagram showing a display example of a screen for viewing a program. In FIG. 4 , since the golf program being broadcast in Tokyo where the user is currently located is also broadcast at the place where the recording device is installed (Osaka), the icon "recordable" is displayed. In addition, it is assumed that the user can perform recording settings on the recording device via a network, for example.

On the other hand, when the currently viewed program is not played at the installation location (Osaka) of the recording device (No in step S105), since the recording cannot be recorded at the installation location of the recording device, the display unit 105 uses the portable terminal 1205 to display the program on the currently viewing screen. "cannot record" icon (step S107).

As described above, after comparing the acquired program list and recordable program list, it is judged whether the currently viewed program is also playing at the place where the video recording device is installed, and an icon showing whether recording is possible or not is displayed on the screen, so that the user can easily judge the current viewing Whether the program can be set to record through the network. In addition, when the user requests setting of recording reservation, desired setting can be performed on the recording device at home through the network.

In addition, in this embodiment, an example of an audio-visual terminal using hardware of a mobile phone has been described, but this embodiment can also be realized by a terminal connected to a network such as a general PDA.

In addition, the unique ID assigned to the program may be used in the determination process (step S105) of whether the currently viewed program is also broadcast at the installation location of the recording device. This ID is an ID assigned to each broadcast program, and a different ID is assigned if the broadcast content is different. In addition, when such an ID is not assigned, it can be realized by matching the broadcast time of the program with the title and performer of the program.

Furthermore, the configuration of the viewing support device described in this embodiment can also be realized by a program built in the mobile terminal 1205 . In addition, only an interface with the user may be installed on the portable terminal 1205, and, for example, a server device such as the electronic program table server 1204 may have a configuration of an audio-visual support device.

First, the browsable program list acquisition unit 103 acquires a browsable program list as a program list at the current position from the received broadcast wave (step S201 ). Here, assume, for example, that the browsable program table shown in FIG. 9 is acquired.

Then, the recording device position acquisition unit 201 accepts the user's input of the installation location of the recording device, and acquires the installation location of the recording device (step S202 ). For example, the recording device position acquisition unit 201 displays a screen for inputting the installation location of the recording device on the screen of the digital television 1605 as shown in FIG. In addition, the user's recording device installation location may be recorded in advance in the mobile phone 1606 or the like (in most cases, the same as the residential area), and when the screen for inputting the recording device installation location shown in FIG. 1606 Enter the region. This makes it possible to set the residential area with one button of the mobile phone 1606 without having to drag the menu to select each time.

The recordable program list acquiring unit 102 accesses the electronic program guide server 1204 via the network, for example, and acquires the recordable program list of the recorder installation location (Osaka) acquired by the recorder location acquirer 201 (step S203). Here, for example, the list of recordable programs shown in FIG. 10 is acquired.

Then, the same program judging unit 202 compares the browsable program table and the recordable program table to judge the same program (step S204). For example, in the browseable program list (Tokyo area) shown in Figure 9, "T TV station" is scheduled to broadcast the program "Entrusted Long Live" from 12:45, in the recordable program list (Osaka area) shown in Figure 10 , "T TV station" is scheduled to broadcast the movie "Magic Home Delivery". And, for the browseable program list shown in Figure 9, "F TV station" is scheduled to play the program "Newlyweds" from 12:05, and in the recordable program list shown in Figure 10, "F TV station" is scheduled to play the program "The resident". In the example shown in FIG. 9 and FIG. 10, since the programs other than the programs "Long Live Entrusted" and "Newlyweds" are the same programs, the identical program determination unit 202 determines that the programs other than the programs "Long Live Entrusted" and "Newlyweds" are the same. same program. In this case, for example, the user has set the remote recording setting for the video recording device (hard disk video recorder 1602) to record the program "Long Live Entrusted" or "Newlyweds" in the program list watched in the Tokyo area. The installation place of the recording device) cannot be recorded because it is not played.

Then, the program list display unit 203 adds a mark indicating that the same program judged by the same program judging unit 202 in the browsable program list can be recorded on the recording device, and displays the program list as shown in FIG. 11 (step S205). In the example shown in FIG. 11 , programs other than "Long Live the Entrustment" and "Newlyweds" are marked, indicating that the programs can be remotely recorded on the recording device by inputting the reservation code with a mobile phone, for example. On the other hand, programs without an additional mark indicate that they can only be viewed in the local area (Tokyo).

As described above, the acquired program list and recordable program list are compared to determine the same program, and displayed on the program list with a mark indicating that it can be recorded on the recording device, so that the user can easily determine the program scheduled to be broadcast at the current location Is it possible to set the video recording through the network.

In addition, in the present embodiment, the program table display unit 203 displays the marked program table, but the present invention is not limited thereto. For example, a selection accepting unit that accepts a user's selection instruction for a program table may be provided, and the program table display unit 203 may display any one of a recordable program table, a browsable program table, and a marked program table according to the user's selection instruction.

(Embodiment 3)

In Embodiments 1 and 2 above, the same program judging units 104 and 202 compare the browsable program table and the recordable program table to judge the same program, thereby judging whether the currently browsing program can be recorded at a remote location. However, the obtained display content of the browseable program list and the recordable program list may not be the same. Abbreviations may also be used depending on the size of the frame on which program content is provided. For example, there are cases where an abbreviated term such as "Professional Baseball N" is used in a program titled "Nippon Professional Baseball News Bulletin". However, the duration of the programs is often the same. Therefore, in the present embodiment, a case will be described in which the identity of programs is judged based on the broadcast time information of the programs and the text information of the program information.

Fig. 12 is a block diagram showing a specific configuration of an identical program judging unit.

The same program judging section judges the identity of each program according to the program table that can be browsed and the program table that can be recorded, as shown in Fig. The degree calculation part 1045 and the judgment part 1046.

The show time extracting unit 1041 extracts the start time, end time and show time of the show of the target program from the browsable program list acquired by the browsable program list acquisition unit 103 . For example, information that the show time of the target program is 30 minutes from 19:00 to 19:30 is extracted.

The search unit 1042 searches the recordable program list acquired by the recordable program list acquisition unit 102, using the start time, end time and show time of the target program. If there is a program with the same start time, end time and show time, then Text information indicating the title, performer, subtitle, program content, etc. of the program is extracted. And, if there is no program with the same start time, end time, and show time, the search unit 1042 searches the list of recordable programs using the show time of the target program, and extracts the text information of the program with the same show time.

The text information extraction unit 1043 extracts text information indicating the title, artist, subtitle, program content, etc. of the target program from the browsable program list acquired by the browsable program list acquisition unit 103 . The program information storage unit 1044 stores text information extracted by the search unit 1042 . For example, if the broadcast time of the target program is 30 minutes, a collection of programs with a broadcast time of 30 minutes is stored as a search result.

The matching degree calculation unit 1045 calculates the matching degree between the target program and the programs stored in the program information storage unit 1044 . That is, the matching degree calculation unit 1045 compares the text information of the target program extracted by the text information extracting unit 1043 with the text information of the program stored in the program information storage unit 1044 to calculate the matching degree of the programs. For example, as shown in Figure 13, the text information of the program is separated into information such as title, content, performer, etc., and sentence processing such as morpheme analysis is performed on each information, and the degree of consistency between words or the relationship between words is calculated. consistency between. Here, the program text information 801 shown in FIG. 13 is an example in which the content is specifically described, and the program text information 802 and 803 are examples in which the content is omitted. For example, there are programs such as program text information 802 in which only a part of the information of performers is described, and there are programs such as program text information 803 in which only the keyword "news" is expressed using "N". In this way, a program in which only a part of the information of the performer is described, and a case where it matches the text information of the program in which it is specifically described, and a case where the title partially matches is calculated as information with a high degree of matching.

The judging unit 1046 judges whether the degree of coincidence between the programs calculated by the degree of coincidence calculating unit 1045 is equal to or greater than a predetermined threshold, and judges that the programs are the same program if it is equal to or greater than the predetermined threshold.

Next, the operation of the identical program judging unit configured in this way will be described. Fig. 14 is a flowchart showing the flow of operations of the identical program judging unit.

The showing time extraction unit 1041 extracts the start time, end time and show time of the show of the target program from the browsable program list (step S601). Then, the search unit 1042 judges whether or not there is a program with the same start time, end time, and broadcast time as the target program in the list of recordable programs (step S602). Here, if there is a program with the same start time, end time and show time (Yes in step S602), then extract the text information representing the title, performer, subtitle, program content, etc. of the program, and store it in the program information storage unit In 1044 (step S603). Next, the text information extraction unit 1043 extracts text information indicating the title, performer, subtitle, program content, etc. of the target program from the browsable program list (step S604).

On the other hand, if the result of the above judgment (step S602) by the search unit 1042 is that there is no program with the same start time, end time and show time (No in step S602), the search unit 1042 uses the show time of the target program to search for a recordable program. program table, and judge whether there are programs with the same showing time (step S609). Here, if there is a program with the same showing time (Yes in step S609), the text information representing the title, performer, subtitle, program content, etc. of the program is extracted and stored in the program information storage unit 1044 (step S610) .

Then, the coincidence degree calculation unit 1045 compares the text information of the target program extracted by the text information extraction unit 1043 with the text information of the program stored in the program information storage unit 1044, and calculates the degree of coincidence between the programs (step S605 ). Then, the judgment unit 1046 judges whether or not the degree of coincidence between the programs calculated by the degree of coincidence calculation unit 1045 is equal to or greater than a predetermined threshold (step S606). As a result, if the degree of coincidence is equal to or greater than the predetermined threshold (YES in step S606), the judging unit 1046 judges that the target program is also shown at the place where the recording device is installed (step S607).

And, as a result of the above judgment (step S608) of the retrieval unit 1042, if there is no program with the same show time (No in step S608), the judging unit 1046 judges that the target program is not shown at the place where the recording device is installed (step S611).

In addition, in Embodiment 2, the identical program determination unit repeats the above-mentioned operation for each program in the browsable program table.

After performing the above operations, it is possible to judge whether it is the same program by using the information of the show time of the program and the text information such as the title, subtitle, and performer of the program recorded in the program table.

In addition, there are cases where the content of the program is different due to the difference in the number of times of broadcasting, even though the title of the TV series is the same. In this case, it is necessary to judge whether or not it is the same program by referring to the past program table and judging how many times it is played. And, conversely, when a future program table is released, it may be determined whether or not it is the same program using the number of broadcast times of the program up to the last time.

That is, detect the playing interval of the target program, estimate the time of the previous broadcast according to the interval, continue to detect whether it has been played before this time if it has been played at this time, and judge that this time is the first time if it is not detected On the broadcast date, it is judged whether or not it is the same program by a broadcast count calculation unit that counts the broadcast count of the target program. A method for calculating the number of times a certain program is played will be described in detail. For example, a case of counting the number of broadcasts of "Program A" will be described. "Program A" was played and ended when "Program A" was searched for in the released past program list, and the number of times of play until "Program A" was played was also counted. Thus, all the times that "program A" was played in the past are counted, and the number of times "program A" in the current segment will not be counted. Therefore, first, the broadcast interval of "program A" is calculated, whether the target "program A" is a weekly program or a daily program. Then, assuming that the playback is played at the playback interval, if it is played every day, it is checked whether it is played in the time period of the previous playback. Generally, there are programs that are broadcast every day only on weekdays and programs that are broadcast every day including holidays. Therefore, with regard to the program that is aired every day, after distinguishing whether it is a program that is aired only on weekdays or a program that is aired every day including holidays, the time slot estimated to be aired last time is retrieved. When it is played in the time period estimated to be played last time, it is also continued to search whether it has been played in the time period estimated to be played last time. Through this repeated operation, if it has not been played in the time period estimated to be the previous play, it is judged that this is the first play, and the play count of "Program A" is calculated using the play count from this time to the present.

In addition, in the case of frequently appearing programs such as news and weather forecasts, the content of the programs may be provided using icons or the like. Therefore, by providing an icon content storage unit that stores the correspondence between icons and their contents in text information, it is possible to determine the correspondence between programs even when the contents of one program table are represented by icons.

(Embodiment 4)

In Embodiments 1 and 2 above, when a browsable program table is acquired, the program table of the recording device installation place where the recording device is installed is obtained, and the coincidence degree of each program is calculated to determine whether they are the same program. However, even if a user with a mobile phone does not obtain the program list at the place where the video recording device is installed when viewing programs at a travel destination, the user usually lives in a home where the video recording device is installed and obtains the program list at the place. In addition, the program table multiplexes not only the currently broadcast program but also the program information to be broadcast in the future into the program content and distributes it.

Therefore, in this embodiment, the program list received at one's own home (installation place of the video recording device) is stored in the portable terminal in advance, for example, when the program list is received at the travel destination and compared with the program list that can be recorded. The case of the already stored program table will be described.

FIG. 15 is a block diagram showing the configuration of an audiovisual support device according to Embodiment 4 of the present invention. In addition, the same code|symbol is attached|subjected to the same part as Embodiment 1, and detailed description is abbreviate|omitted.

The audio-visual support device 110 is a device that supports the user's viewing and listening of programs. As shown in FIG. , the corresponding program list acquisition unit 115 , the same program determination unit 104 and the display unit 105 .

The recordable program list storage unit 111 stores a recordable program list. The browsable program list storage unit 112 stores a browsable program list.

The recordable program list update unit 113 stores the acquired program list in the recordable program list storage unit 111 when acquiring a new program list at the installation location of the recording device. In particular, schedules for future showings are acquired and stored. When broadcast content is acquired and browsed by a mobile phone or the like, information related to a program table that is simultaneously multiplexed and broadcast is acquired and stored regardless of whether the user has browsed or not. Furthermore, when the recordable program list updating unit 113 acquires a program list other than the place where the video recording device is installed, it stores it in the browsable program list storage unit 112 .

When the corresponding program list determination unit 114 acquires a program list other than the installation location of the video recording device through the recordable program list update unit 113, it judges the program stored in the browsable program list storage unit 112 corresponding to the video recording device installation location. Whether or not a table (for example, a program table including the date and time zone of the program for identity determination: hereinafter referred to as a corresponding program table) is already stored in the recordable program table storage unit 111 .

The corresponding program list acquisition unit 115 acquires a program list shown at the place where the video recording device is installed, through a network or the like when it determines that the corresponding program list is not stored in the corresponding program list determination unit 114 . In addition, when it is judged that a corresponding program table is stored in the corresponding program table determination unit 114 , the corresponding program table acquisition unit 115 does not newly acquire the program table.

When the corresponding program list is stored, the identical program determination unit 104 uses the program list stored in the browsable program list storage unit 112 and the recordable program list stored in the recordable program list storage unit 111 to determine the same program as in the above-mentioned embodiment. Whether it is the same program. On the other hand, when the corresponding program list is not stored, the same program determination unit 104 uses the program list stored in the browsable program list storage unit 112 and the recordable program list acquired by the corresponding program list acquisition unit 115, which is the same as the above-mentioned embodiment. The method is the same to judge whether it is the same program.

Next, the operation of judging the same program by the viewing support device 110 configured as described above will be described. FIG. 16 is a flowchart showing the operation flow of the identical program determination by the viewing support device 110 .

First, the recordable program table update unit 113 acquires the program table at the current location through the received broadcast wave (step S701). Then, the recordable program list update unit 113 deletes the information of the programs that have already been broadcast from the program list stored in the recordable program list storage unit 111 (step S702). Then, the recordable program list update unit 113 judges whether the acquired program list is a program list other than the place where the recording device is installed (step S703 ). As a result, when the acquired program table is not a program table outside the installation place of the recording device (No in step S703), the recordable program table updating unit 113 stores the acquired program table in the recordable program table storage unit 111, And repeat the above actions (step S703→step S701). In addition, here, the installation location of the recording device is set in advance.

On the other hand, when the acquired program list is not located in the place where the recording device is installed (Yes in step S703 ), the recordable program list update unit 113 stores the acquired program list in the browsable program list storage unit 112 . Then, the corresponding program table judgment unit 114 judges whether or not the program table corresponding to the acquired program table at the place where the video recording device is installed is already stored in the recordable program table storage unit 111 (step S704). Here, when the corresponding program table has already been stored (YES in step S704), the same program determination unit 104 uses the program table stored in the browsable program table storage unit 112 and the program table stored in the recordable program table storage unit 111, The same program is judged (step S705). On the other hand, when the corresponding program table is not stored (No in step S704), the corresponding program table acquisition unit 115 obtains a program table shown at the place where the recording device is installed through the network or the like (step S706). Then, the same program determination unit 104 determines the same program using the program table stored in the browsable program table storage unit 112 and the program table acquired by the corresponding program table acquisition unit 115 (step S705).

As described above, when the program table of the location where the video recording device is installed has already been stored, it is possible to determine whether remote recording is possible without reacquiring the program table. In addition, if the program table of the location where the video recording device is installed is not stored, it is also possible to determine whether remote recording is possible by reacquiring the program table of the location where the video recording device is installed via the network.

(Embodiment 5)

The information of the program list may be distributed by a plurality of operators and may differ from region to region. In this case, even the same program is often provided with a program table using a different expression method. Therefore, in this embodiment, when the source of the program table at the installation place of the video recording device is different from the source of the program table that can be browsed (at the current position), the program table with the same source is acquired and used for judging the same program The situation is explained.

FIG. 17 is a block diagram showing the configuration of an audiovisual support device according to Embodiment 5 of the present invention. In addition, the same code|symbol is attached|subjected to the same part as Embodiment 1, and detailed description is abbreviate|omitted. In addition, the hardware configuration used by the viewing support device is also the same as that of the first embodiment shown in FIG. 2 .

The audio-visual support device 120 is a device that supports user's viewing and listening of programs. As shown in FIG. The judging unit 104 and the display unit 105.

The source detection unit 121 detects the sources of the browsable program list acquired by the browsable program list acquisition unit 103 and the recordable program list acquired by the recordable program list acquisition unit 102 , and determines whether the respective sources are the same.

The program list acquisition unit 122 acquires program lists from sources that provide program lists at both the installation location and the current location of the recording device, when the source of the program list that can be browsed and the program list that can be recorded are different.

Next, the operation of judging the same program by the viewing support device 120 configured as described above will be described. FIG. 18 is a flowchart showing the operation flow of the identical program determination by the viewing support device 120 .

First, the browsable program list acquisition unit 103 acquires a browsable program list as a program list at the current position from the received broadcast wave (step S801 ). Then, the recordable program table acquisition unit 102 accesses the electronic program table server 1204 via the network, for example, to obtain a recordable program table of a recording device installation location (step S802 ). In addition, here, the installation location of the recording device is set in advance.

The providing source detecting unit 121 detects the providing sources of the browsable program list and the recordable program list, and judges whether the respective providing sources are the same (step S803). As a result, when the source of the browsable program table and the recordable program table are the same (Yes in step S803), the identical program judging unit 104 uses the browsable program table and the recordable program table to judge the same program (step S804) . On the other hand, when the source of the program table that can be browsed and the program table that can be recorded are different (No in step S803), the program table acquisition unit 122 accesses the electronic program table server 1204 through the network, for example, and retrieves the location where the recording device is installed and the current location. Both parties provide the source of the program table, and acquire the program table of the source at the installation place and current position of the video recording device (step S805). Then, the same program judgment unit 104 judges the same program by using the browsable program table and the recordable program table obtained by the program table acquisition unit 122 with the same source (step S804 ).

As described above, when the source of the program table that can be browsed and the program table that can be recorded are different, the program table that provides the same source is obtained and used for judging the same program, so it is possible to prevent the same program from being distributed due to different distribution operators. In the case where the presentation modes of the programs are different, it is possible to judge the same program with higher accuracy.

In addition, in each of the above-mentioned embodiments, icons such as "recording possible" and marks indicating that recording is possible are displayed, but the present invention is not limited thereto. For example, as shown in Figure 19 (a), for the same program, when the languages issued at the place where the recording device is installed and at the current location are different, the language for issuing the program can also be extracted from the list of recordable programs, and shown in Figure 19 ( As shown in b), the language of the installation location of the recording device is displayed. This enables the user to select whether or not to perform recording in accordance with the published language.

(Embodiment 6)

In recent years, it has become easier to store viewing histories of televisions and the like due to the reduction in price of hard disks and the like. Therefore, the user's preference can be extracted from the viewing history in the user's daily life, and a program that can be watched can be recommended based on the program information. Furthermore, due to the miniaturization of the hardware of the communication equipment, an environment where content can be viewed and played anywhere is gradually being improved. Therefore, even if the user's preferences obtained from the usual viewing history are used for program recommendation at travel destinations, programs are selected based on the same preferences as usual, so programs that can only be viewed at travel destinations cannot be recommended.

Therefore, in this embodiment, an apparatus is provided for preferentially recommending programs that can only be viewed at the travel destination when viewing a program in a place away from the residential area such as travel.

FIG. 20 is a block diagram showing the configuration of an audiovisual support device according to Embodiment 6 of the present invention.

Viewing and listening support device 300 is a device that supports users to view and listen to programs. Section 306.

The viewing history storage unit 301 acquires and stores viewing histories of programs. The program list acquisition unit 302 receives and acquires a program list of broadcast content and program information related to the program. The preference information extracting unit 303 extracts the user's preference information from the viewing history stored in the viewing history storage unit 301 and the program information of the program watched. The residential area program list storage unit 304 stores the program list acquired by the program list acquisition unit 302 and broadcast in the residential area where the user usually lives (hereinafter referred to as the residential area program list). The browsable program list storage unit 305 stores the program list acquired by the program list acquisition unit 302 that can be viewed in the current area (hereinafter referred to as a browsable program list). The program recommendation unit 306 preferentially selects programs not included in the program list in the residential area based on the preference information of the user among the programs in the browsable program list.

21 is a configuration diagram showing an example of a hardware configuration used in an audiovisual support device according to Embodiment 6 of the present invention. The system has: a digital TV 2201, which receives digital broadcasts; a hard disk video recorder 2202, which can store digital broadcasts on a hard disk; a home gateway 2203, which connects network devices at home to the network outside the home; and a portable phone 2204, which can receive and watch Digital broadcast and has audio-visual support device 300 .

Next, the operation when the user watches a program using the mobile phone 2204 having the viewing support device 300 configured as described above will be described. FIG. 22 is a flowchart showing the flow of operations when the user watches a program on the mobile phone 2204 .

The viewing history storage unit 301 stores information related to the start and end date and time of viewing, information related to the channel viewed and listened to, and the title information in the program information acquired by the program list obtaining unit 302 as viewing history (step S301 ). In addition, it is assumed here that the program information released by the service operator that distributes the program includes the title of each program preset by the service operator.

The preference information extraction unit 303 judges whether or not a preset viewing time (for example, 40 hours) is stored in the viewing history (step S302 ). Here, when the set viewing time has not elapsed (step S302: No), viewing of the program by the user and storage of the viewing history by the viewing history storage unit 301 are repeated.

On the other hand, when exceeding the set viewing time (Yes in step S302), the preference information extracting unit 303 judges that the user's preference can be extracted from the viewing history, and extracts the user's preference from the statistical information of the viewing history ( Step S303). That is, the preference information extraction unit 303 calculates the total viewing time for each title as shown in FIG. 23 , for example, based on the viewing history stored in the viewing history storage unit 301 . In the example shown in FIG. 23 , it is known from the viewing history that the user likes watching sports programs. In addition, in this embodiment, it is assumed that the broadcast program is pre-applied with information related to the title, but it is also possible to use a natural language processing method or the like to extract characteristic keywords from the text information of the program content.

The program table acquisition unit 302 obtains the residential area program table and stores it in the residential area program table storage unit 304 (step S304). Here, it is assumed that the program table of the residential area up to, for example, one month later is acquired and stored. In addition, it is assumed that the acquisition and storage of the residential area program table is performed when the user is in the residential area.

The program list acquisition unit 302 acquires the browsable program list at the current location and stores it in the browsable program list storage unit 305 (step S305).

The program recommendation unit 306 compares the residential area program table and the browsable program table to determine whether they are the same (step S306). The result of this judgment is that when the residential area program list and the browseable program list are different (step S306 is No), the program recommendation unit 306 selects programs that are not included in the residential area program list from the programs in the browsable program list, and selects these programs Among them, programs matching the user's preference information extracted by the preference information extraction unit 303 are recommended as recommended programs, and are displayed and recommended, for example, as shown in FIG. 24 (step S307). For example, when the user's current location is far away from the residential area, the program list of the residential area is different from the list of programs that can be browsed. That is, programs that are broadcast in the area where the user is currently located but not broadcast in the user's residential area are preferentially recommended.

On the other hand, when the result of the judgment is that the program table in the residential area is the same as the program table that can be browsed (YES in step S306), the program recommendation unit 306 selects a program that matches the user's preference information from the programs in the program table that can be browsed as a recommended program. The program is recommended (step S308).

As described above, programs that are broadcast only in places other than the user's living area, such as travel destinations or business trip destinations, can be strongly recommended, so that programs that can only be viewed at moving destinations can be prevented from being missed.

(Embodiment 7)

When recording a program watched by a mobile phone, it is difficult to record a clear program because the mobile phone cannot receive radio waves in a stable state because the mobile phone is carried and moved. In addition, when it is intended to record the playback viewed by the mobile phone using the video recording device at home through remote operation, the video cannot be recorded immediately. Therefore, in this embodiment, a system for cooperatively recording a program using a mobile phone and a recording device at home will be described.

Fig. 25 is a block diagram showing the configuration of a program recording system according to Embodiment 7 of the present invention.

The program recording system is a system in which two recording devices cooperate to record a program, and includes a first recording device 400 and a second recording device 500 connected to the first recording device 400 via a network.

The first recording device 400 is, for example, a mobile phone or the like, and includes a first program receiving unit 401 , a first program recording unit 402 , a recording instruction sending unit 403 , and a recording information receiving unit 404 . On the other hand, the second recording device 500 is, for example, a recording device installed at home, and includes a second program receiving unit 501 , a second program recording unit 502 , a recording instruction receiving unit 503 , and a recording information sending unit 504 .

The first program receiving unit 401 receives a program that is being broadcast. The first program recording unit 402 records the program received by the first program receiving unit 401 . The recording instruction sending unit 403 sends to the second recording device 500 a recording instruction for the program being recorded by the first program recording unit 402 . The recording information receiving unit 404 receives recording information including the recording start time and recording ID transmitted from the second recording device 500 .

The recording instruction receiving unit 503 receives the program recording instruction sent from the first recording device 400 .

The recording information sending unit 504 sends recording information including the time when the second program recording unit 502 started recording and the generated recording ID to the first recording device 400 .

26 is a configuration diagram showing an example of a hardware configuration used in a program recording system according to Embodiment 7 of the present invention. This system has: digital television 2701, receives digital broadcast; Hard disk video recorder 2702, as the 2nd video recording device 500 that can store digital broadcast on hard disk; Home gateway 2703, connects the network equipment in the home with the network outside the home; Portable phone 2704, the first video recording device 400 capable of receiving and viewing digital broadcasts; and the program storage semiconductor medium 2705, which can store contents such as broadcasts.

Next, an operation when recording a program viewed by mobile phone 2704 in first recording device 400 of the program recording system configured as described above will be described. Fig. 27 is a flowchart showing the flow of operations when a program is recorded by the program recording system.

It is assumed here that, for example, when a user watches a sports program on mobile phone 2704 as shown in FIG.

In the first recording device 400 (mobile phone 2704), when the user requests recording of a program being viewed (step S401), the first program recording unit 402 starts recording the requested program (step S402). It is assumed here that the first program recording unit 402 stores the program in the program storage semiconductor medium 2705 installed in the mobile phone 2704 . And, the 1st program recording unit 402 simultaneously stores, for example, the file name shown in FIG. 29 (for example, "001. Rebroadcast", etc.) and other information.

At the same time, the recording instruction sending unit 403 sends a recording instruction of the program requested to be recorded to the second recording device 500 through the network and the home gateway (step S403). At this time, the recording instruction sending unit 403 sends the recording instruction including the channel information of the program for which recording is requested.

The recording instruction receiving unit 503 of the second recording device 500 (hard disk recorder 2702) receives the recording instruction transmitted from the first recording device 400 (step S404). Then, the recording instruction receiving unit 503 notifies the second program receiving unit 501 of the channel information, and notifies the second recorded program recording unit 502 of the recording instruction.

The second program receiving unit 501 receives broadcasting of the notified channel. The second program recording unit 502 generates a recording ID for specifying a program instructed to record (step S405). Then, the second program recording unit 502 starts recording the program received by the second program receiving unit 501 corresponding to the recording ID (step S405). FIG. 30 is a diagram showing an example of recording information of a program recorded on the second recording device 500 . In the example shown in FIG. 30 , information such as a recording ID, a recording date, a recording start time, a title, and a recording setting source are stored as recording information. In addition, information such as a direct recording request, a recording reservation, and a recording setting by a mobile phone is stored in the recording setting source.

Then, the recording information transmitting unit 504 transmits the recording ID and recording start time as recording information to the first recording device 400 (step S407). Thereby, the first video recording device 400 is notified that the video recording on the second video recording device 500 has started.

The recording information receiving unit 404 of the first recording device 400 receives the recording information including the recording start time and recording ID transmitted from the second recording device 500, and notifies the first program recording unit 402 (step S408). Here, if the program instructed to record is "sports broadcast" shown in FIG. 30, "12" is received as the recording ID.

When notified of the recording ID, the first program recording unit 402 displays, for example, a message as shown in FIG. 32 and ends the recording of the program being recorded (step S409). At this time, the first program recording unit 402 stores the recording ID in association with the program whose recording has been completed. Thus, in the program storage semiconductor medium 2705, for example, as shown in FIG. 29, in addition to information such as the file name, recording start time, title, etc., the recording ID (such as "12" etc.), recording end time (such as "9 o'clock") is also stored. 10 minutes 13 seconds", etc.) information.

As mentioned above, at the stage when the first video recording device 400 (mobile phone 2704) has made a recording request of a program, the recording on the first video recording device 400 is started, and before the recording on the second video recording device 500 (hard disk video recorder 2702) is started , the video recording at the first video recording device 400 has been continued. Then, when the recording by the second recording device 500 starts, the recording by the first recording device 400 ends. Thus, the first video recording device 400 can start recording the program that the user is watching with the first video recording device 400, and instruct the second video recording device 500 to record, and the user can easily record the program using the second video recording device 500 that can receive stably. The desired program is recorded.

Furthermore, it is also effective not only when the radio wave state is unstable, but also when, for example, the remaining battery power decreases or the capacity of the memory decreases.

And, the 2nd video recording device 500 can obtain the program recorded on the 1st video recording device 400 by inserting the semiconductor memory recorded by the 1st video recording device 400 into the interface, and make this program and the program recorded in the 2nd program recording unit 502 program combined. In this case, it is possible to determine which program the subsequent part of the program recorded by the first recording device 400 is recorded by the second program recording unit 502 based on the recording ID, and combine them. Accordingly, the programs partially recorded by the first recording device 400 and the second program recording unit 502 can be recognized as one program, for example, as shown in FIG. 31 .

And, in this embodiment, by inserting the semiconductor memory recorded by the first video recording device 400 into the interface of the second video recording device 500, the program recorded in the first video recording device 400 and the program recorded in the second video recording device 500 The programs are combined and achieve continuous audio-visual. However, if a sufficient frequency band can be ensured between the first video recording device 400 and the second video recording device 500, by sending the completed program recorded on the second video recording device 500 to the first video recording device 400, the first video recording device 400 can Combine the programs and play them. Thus, the user only needs to operate the first video recording device 400, and the program can be recorded by the first video recording device 400, and since the program is recorded on the second video recording device 500, the battery of the first video recording device 400 will not be consumed, and the program can be recorded through a fixed The antenna receives programs and can record clear images.

And, in this embodiment, carry out the communication with the 2nd video recording device 500 after having the video recording instruction of the 1st video recording device 400, but also can carry out with the 2nd video recording when the program browsing operation of the 1st video recording device 400 starts. Communication of device 500 . Thereby, recording can be started immediately when there is a recording instruction from the first recording device 400 . Furthermore, the recording of the program may be started on the second recording device 500 when the program browsing on the first recording device 400 is started. Thus, when there is a recording instruction from the first recording device 400, it is possible to continuously record a program that has already started broadcasting.

(Embodiment 8)

In Embodiment 7, the case where a mobile phone and a video recording device at home are used to cooperatively record a program is described, but in this embodiment, it is also described that a mobile phone is used to determine whether or not a program instructed to be recorded is shown at the installation location of the video recording device at home. , when performing a recording instruction.

Fig. 33 is a block diagram showing the configuration of a program recording system according to Embodiment 8 of the present invention. In addition, the same code|symbol is attached|subjected to the same part as Embodiment 1 and Embodiment 7, and detailed description is abbreviate|omitted.

In the program recording system of this embodiment, the first recording device 410 has a recordable program list acquisition unit 102 as shown in FIG. part 103, and the same program judging part 411.

The identical program determination unit 411 compares the list of programs that can be browsed and the list of programs that can be recorded, and determines whether the same program as the program being recorded by the first program recording unit 402 is shown at the installation location of the second recording device 500 . When it is judged that the same program is broadcast at the installation location of the second recording device 500 , the recording instruction sending unit 412 sends a recording instruction of the program being recorded by the first program recording unit 402 to the second recording device 500 . On the other hand, when it is judged that the same program is not shown at the installation location of the second video recording device 500, the same program determination unit 411 displays, for example, a message "This program is not shown at the installation location of the second video recording device 500".

As described above, it is possible to prevent recording of a different program on the second recording device 500 by instructing recording after judging whether the program for which the first recording device 410 has requested recording is shown at the location where the second recording device 500 is installed. .

(Embodiment 9)

For example, in the program recording system as in Embodiment 7 above, the program recorded by the first recording device and the program recorded by the second recording device may have different levels of volume or the like depending on the recording device. When recording content is combined at different volumes, it may be necessary to adjust the volume during playback before and after the combined part of the content. Therefore, in this embodiment, a case where the volume levels of the contents recorded by the respective recording devices are corrected and then combined will be described.

Fig. 34 is a block diagram showing the configuration of a second recording device of the program recording system according to Embodiment 9 of the present invention. In addition, since the configuration of the first recording device is the same as that of Embodiment 7, description thereof will be omitted.

The second video recording device 510 is, for example, a video recording device installed at home. As shown in FIG. Calculation unit 515 and recorded program combination unit 516 .

The recorded program acquisition unit 511 acquires the program recorded by the first recording device 400 (hereinafter referred to as first recorded content) from, for example, a semiconductor memory in which the first recording device 400 recorded the program. The recorded program storage unit 512 stores a program recorded in accordance with a recording instruction from the first recording device 400 (hereinafter referred to as second recorded content). The sampled video extracting unit 513 extracts content data (hereinafter referred to as sampled video) at a common time between the first recorded content acquired by the recorded program acquiring unit 511 and the second recorded content stored in the recorded program storage unit 512 . In addition, content data for a predetermined amount of time is recorded in both the first recorded content and the second recorded content.

The volume power measurement unit 514 measures the volume power of the sample video extracted by the sample video extraction unit 513 . 35 is a diagram showing an example of the volume power of sample video measured by the volume power measuring unit, (a) is an exemplary diagram showing the first recorded content, and (b) is an exemplary diagram showing the second recorded content. As shown in FIGS. 35( a ) and ( b ), the waveforms are the same but the amplitudes are different in the first recorded content and the second recorded content.

The volume power correction amount calculation unit 515 calculates the average volume power of the volume power in the sample video of the first recorded content and the second recorded content, and calculates the correction amount of the volume power so that the volume power in the sample video of the first recorded content The average volume power of is consistent with the average volume power of the volume power in the sample animation of the second recorded content. In addition, here, the volume power correction amount is calculated so that the average volume power of the first recorded content matches the average volume power of the second recorded content, but the present invention is not limited thereto. For example, it is also possible to reversely calculate the correction amount of the volume power so that the average volume power of the second recording content matches the average volume power of the first recording content, and also calculate the correction amount of the volume power so that the average volume power of the first recording content The volume power and the average volume power of the second recorded content match the middle volume power.

The recorded program combination unit 516 corrects the volume power of the first recorded content according to the volume power correction amount calculated by the volume power correction amount calculation unit 515 and combines the first recorded content and the second recorded content.

Next, the operation when the first recorded content and the second recorded content are combined by the second recording device 510 configured as described above will be described. FIG. 36 is a flowchart showing an operation flow when the second recording device 510 combines the first recording content and the second recording content.

The sample video extracting unit 513 extracts sample video from the first recorded content acquired by the recorded program acquiring unit 511 and the second recorded content stored in the recorded program storage unit 512 (step S901 ). Then, the volume power measurement unit 514 measures the volume power of each sample video extracted by the sample video extraction unit 513 (step S902 ). Then, the volume power correction amount calculation unit 515 calculates the volume power correction amount so that the average volume power of the volume power in the sample video of the first recorded content is equal to the average volume power of the volume power in the sample video of the second recorded content. Matching (step S903). Then, the recorded program combining unit 516 corrects the volume power of the first recorded content according to the correction amount of the volume power, and combines the first recorded content and the second recorded content (step S904 ).

As described above, since the volume power of each recorded content is corrected and combined by using the recorded portion shown at the same time, there is no need to adjust the volume again during playback.

(Embodiment 10)

For example, in the program recording system as in Embodiment 7 above, if the program recorded by the first recording device is simply combined with the program recorded by the second recording device, there is a high possibility of image distortion and the like occurring in the switching portion. . Therefore, in this embodiment, a case where recording contents are combined using program clips will be described.

37 is a block diagram showing the configuration of a second recording device in the program recording system according to Embodiment 10 of the present invention. In addition, the same part as Embodiment 9 is assigned the same code|symbol, and detailed description is abbreviate|omitted.

The program scene change detection unit 522 detects a scene change based on the tag information extracted by the program content tag extraction unit 521 . FIG. 39 is a diagram showing an example of a scene structure of a program.

The recorded program combining unit 523 detects the scene switching portion of the program detected by the program scene switching portion detection unit 522 in the common time portion between the first recorded content acquired by the recorded program acquiring unit 511 and the second recorded content stored in the recorded program storage unit 512. The scene switching part 810 shown in FIG. 38 combines the first recorded content and the second recorded content.

As described above, since the clip joints of the programs are detected using the tag information of the recorded programs and the recorded content is combined using the program clip joints, it is possible to realize the combination of the recorded programs with good viewing effect.

(Embodiment 11)

In the case of recorded content such as digital broadcasting, copying of the recorded content to other media is often restricted from the viewpoint of copyright protection. Therefore, for example, in the program recording system like the seventh embodiment described above, there may be cases where the content recorded by the mobile phone cannot be combined with the content recorded at home where the recording device is installed. Therefore, in this embodiment, a program recording system that can integrate content even when copying to another medium is restricted will be described.

Fig. 40 is a block diagram showing the configuration of a second recording device in the program recording system according to Embodiment 11 of the present invention. In addition, the same part as Embodiment 9 is assigned the same code|symbol, and detailed description is abbreviate|omitted.

The second recording device 530 is, for example, a recording device located at home, and has a recording program acquisition part 511, a recording program storage part 512, a program combining key judgment part 531, a recording program combining part 533, and a recording program Delete part 533 .

The program combination key determination unit 531 extracts a combination key from the first recorded content acquired by the recorded program acquisition unit 511 , and determines whether the extracted combination key is stored in the second recorded content in the recorded program storage unit 512 . The recorded program combining unit 532 combines the first recorded content and the second recorded content only when the combined key extracted from the first recorded content exists in the second recorded content.

After the recorded program deleting unit 533 combines the first recorded content and the second recorded content by the recorded program combining unit 532, the recorded program acquired by the recorded program obtaining unit 511, for example, the program recorded by the first recording device 400, obtains the first recorded content. Delete the first recording content in the semiconductor memory of the device.

Next, the operation when the first recording content and the second recording content are combined by the second recording device 530 configured as described above will be described. FIG. 41 is a flowchart showing an operation flow when the second recording device 530 combines the first recording content and the second recording content.

The program combination key determination unit 531 extracts a combination key from the first recorded content acquired by the recorded program acquisition unit 511 (step S1001). Then, the program combination key determination unit 531 determines whether the extracted combination key is stored in the second recorded content in the recorded program storage unit 512 (step S1002). When the result is that the extracted combination key exists in the second recorded content (YES in step S1002), the recorded program combining unit 532 combines the first recorded content and the second recorded content (step S1003). Then, the recorded program deletion unit 533 deletes the first recorded content from the semiconductor memory in which the first recorded content was acquired by the recorded program acquisition unit 511, for example, the program recorded by the first recording device 400 (step S1004).

On the other hand, when the extracted combination key does not exist in the second recorded content (No in step S1002), the user is notified that the first recorded content and the second recorded content cannot be combined (step S1005).

As described above, by allowing the copying of the content recorded by the first recording device 400 to the recorded content having the combination key, program combination can be performed only for recorded programs acquired in this embodiment. In addition, by prohibiting copying to a medium that does not have a binding key, it is also possible to prevent unauthorized copying of recorded content.

(Embodiment 12)

In Embodiment 7, a case was described in which a video recording device at home is in a video recording capable state when a video recording request is received from a mobile phone. However, generally, the video recording device at home is operated by a user who uses it at home, so it may not always be available when a video recording request is sent from a mobile phone. Therefore, in this embodiment, a case will be described in which, when a recording request is issued from a mobile phone, and the video recording device at home is in a state where recording cannot be performed, the mobile phone is notified of this fact and the mobile phone is made to record; When the video recording device of the mobile phone is in a state capable of recording, the program designated by the mobile phone is recorded by the video recording device at home and the recording of the mobile phone is stopped.

Fig. 42 is a block diagram showing the configuration of a program recording system according to Embodiment 12 of the present invention. In addition, the same part as Embodiment 7 is assigned the same code|symbol, and detailed description is abbreviate|omitted. In addition, since the hardware configuration used in the program recording system of this embodiment is the same as that of Embodiment 7 shown in FIG. 26, description thereof will be omitted.

The second video recording device 700 further includes a video recording permission judging unit 701 in addition to the configuration of the seventh embodiment. Furthermore, the operations of the recording information receiving unit 601 and the first program recording unit 602 of the first recording device 600 and the recording information transmitting unit 702 of the second recording device 700 are different from those of the seventh embodiment. The recording possibility determination unit 701 determines whether or not the program instructed to be recorded by the first recording device 600 can be recorded by the second program recording unit 502 .

Next, an operation when recording a program viewed by mobile phone 2704 in first recording device 600 of the program recording system configured as described above will be described. Fig. 43 is a flowchart showing the flow of operations when a program is recorded by the program recording system. In addition, the same part as Embodiment 7 is assigned the same code|symbol, and detailed description is abbreviate|omitted.

First, the process from the user's request to record the program to be viewed (step S401) to the recording instruction receiving unit 503 of the second recording device 700 receiving the recording instruction (step S404) is the same as in the seventh embodiment.

Then, the recording permission judging unit 701 judges whether or not the program instructed to be recorded by the first recording device 600 has been recorded in the second program recording unit 502 (step S501). Here, when the recording has already been recorded (YES in step S501), the recording information transmitting unit 702 notifies the first recording device 600 that the program for which recording was instructed has been recorded (step S502). The recording information receiving unit 601 of the first recording device 600 receives the notification that the program instructed to be recorded has been recorded, and notifies the first program recording unit 602 (step S503). When the first program recording unit 602 is notified that the program instructed to be recorded has been recorded, it displays, for example, a message as shown in FIG. 45 and ends the recording of the program being recorded (step S504). In addition, since the program has already been recorded by the second recording device 700, the program recorded by the first recording device 600 before that can also be deleted.

On the other hand, when the program instructed to be recorded by the first recording device 600 is not recorded (No in step S501), the recording possibility determination part 701 uses the program list to confirm the end time of the program instructed to be recorded, and determines whether the recording is possible before the end time Video recording (step S505). Here, when the recording cannot be performed (No in step S505), the recording information transmitting unit 702 notifies the first recording device 600 that the recording cannot be performed (step S506). In addition, the recording permission determination unit 701 repeats the determination process when recording is possible before the end time of the program instructed to be recorded.

The recording information receiving unit 601 of the first recording device 600 that has received the notification that recording cannot be performed notifies the first program recording unit 602 (step S507). When the first program recording unit 602 is notified that the recording cannot be performed, for example, a message as shown in FIG. 44 is displayed and the recording of the program being recorded is continued (step S508).

For example, it is assumed that the start time of the program recorded by the first video recording device 600 is 14:00, the end time is 16:00, and the current time is 14:15. In order to record this program by the second program recording unit 502 of the second recording device 700 before the end time, other programs cannot be recorded before 16:00. Here, under the situation of recording other programs from 15:00 to 15:30 in the previous reservation setting, in order to record the program scheduled for recording in advance, so utilize the first recording device 600 to store the program before 15:30, Utilize the 2nd video recording device 700 video recording from 15:30 to 16:00.

On the other hand, when video recording is possible (YES in step S505), the process from the process of generating the recording ID by the second program recording unit 502 (step S405) to the program being recorded by the first program recording unit 402 is performed in the same manner as in Embodiment 7. The recording end processing (step S409). Furthermore, the same applies to the case where the last second program recording unit 502 is in a recordable state. In the above example, it is judged that video recording is possible at 15:30. Until then, video recording by the first video recording device 600 is continued.

As described above, when a video recording instruction is given from the first video recording device to the second video recording device, the first video recording device continues video recording, etc. according to the use of the second video recording device, etc., so it is possible to easily perform video recording according to the situation. .

As mentioned above, the audio-visual support device related to the present invention can support the audio-visual and video recording of programs according to the user's residential area and current location. Audiovisual and video programs are useful.
