The designating means designates a desired program from a plurality of programs in the program guide data. The extraction means extracts one or a plurality of broadcast data portions included in the broadcast time of the designated program from a plurality of broadcast files based on the program guide data. When a plurality of broadcast data portions are extracted, the reproduction means continuously reproduces the broadcast data portions in order of the broadcast time.

  The air check device according to the present invention stores broadcast data by dividing it into a plurality of broadcast files in association with broadcast times. For this reason, one program may be stored in two broadcast files. However, since the broadcast file is stored in association with the broadcast time, a plurality of broadcast data portions within the broadcast time of the program for which the corresponding broadcast time is designated can be extracted from the plurality of broadcast files. . Therefore, if the plurality of extracted broadcast partial data are reproduced in order of the broadcast time, the broadcast data of the designated program can be reproduced smoothly.

  Preferably, the air check device further includes display means. The display means displays the broadcast time of the designated program and the broadcast time of the extracted broadcast data portion.

  In this case, the user of the air check device can grasp the time zone in which broadcast data exists and the time zone in which broadcast data does not exist among the broadcast times of the designated program.

  Preferably, the display unit displays the broadcast time of the designated program and the broadcast time corresponding to the extracted broadcast data portion in a graph.

  In this case, since the user can visually understand the broadcast time of the designated program and the broadcast time of the broadcast data portion, the time zone where the broadcast data exists and the broadcast data out of the broadcast time of the designated program. You can see at a glance when there is no time zone.

  The air check device according to the present invention can be connected to a server. The air check device includes a program guide acquisition unit, a reception unit, a storage unit, a designation unit, an extraction unit, and a display unit. The program guide acquisition means acquires program guide data including specific information of a plurality of programs broadcast from a broadcasting station and broadcast times of the programs from the server. The receiving means receives broadcast data including a plurality of programs broadcast from a broadcasting station. The storage means stores the received broadcast data in a plurality of broadcast files in association with the broadcast time. The designating means designates a desired program from a plurality of programs in the program guide data. The extraction means extracts one or a plurality of broadcast data portions included in the broadcast time of the program for which the broadcast time is designated from the plurality of broadcast files based on the program guide data. The display means displays the broadcast time of the designated program and the broadcast time of the extracted broadcast data portion.

  The air check device according to the present invention extracts the broadcast data portion within the broadcast time of the designated program by the extraction means, and the broadcast time of the designated program and the extracted broadcast data portion. Broadcast time is displayed. Therefore, when some broadcast data of a program is missing, if the user looks at the displayed broadcast time, the broadcast data of which time zone exists in the broadcast time of the program, and the broadcast of which time zone You can see if there is no data.

  The air check program according to the present invention realizes the above-described means in a computer mounted on an air check device.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

[overall structure]
Referring to FIG. 1, an air check system 10 according to an embodiment of the present invention is for automatically acquiring a desired program from a radio frequency modulation (FM) broadcast. The air check system includes a program guide supply server 12 connected to the Internet 11, a personal computer (PC) 13 connected to the Internet 11, and an FM tuner 14 connected to the PC 13. A plurality of broadcast station servers 16 are also connected to the Internet 11. The program guide supply server 12 is managed by a provider who provides this service, and the broadcast station server 16 is mainly managed by a broadcast station that broadcasts radio programs such as music programs, talk programs, and news programs. The PC 13 and the FM tuner 14 are the property of the user who is the viewer.

  The program guide supply server 12 acquires program guide data (hereinafter simply referred to as a program guide) from each broadcast station server 16 and provides it to the PC 13 of each user. The program guide includes a schedule of programs broadcast by each broadcasting station. The PC 13 functions as a client that can access the program guide supply server 12. The PC 13 and the FM tuner 14 constitute an air check device 80.

  As shown in FIG. 2, the PC 13 is a general-purpose device. As shown in FIG. 2, the hardware configuration includes a CPU (Central Processing Unit) 131, a ROM (Read Only Memory) and a RAM (Random Access Memory) 132, a hard disk drive (HDD). 133, a display 134, an input device 135 such as a keyboard and a mouse, and the like. An air check program described later is installed in the PC 13. The FM tuner 14 receives FM broadcasts from each broadcasting station and supplies the received broadcast data to the PC 13.

[Configuration of program guide supply server]
With reference to FIG. 3, the program guide supply server 12 includes an acquisition unit 20, a format conversion unit 21, and a web server 23. The acquisition unit 20 accesses each broadcast station server 16 and acquires the program table 24 uploaded thereto.

  In the program table 24 provided from each broadcasting station, a schedule of programs scheduled to be broadcast by the broadcasting station is recorded. Specifically, a plurality of program information PI [n] (n is a natural number), which is information related to the program, is recorded in the order of broadcasting. The program information PI [n] includes the broadcast time of the program and meta information for specifying the program such as the program name, the performer, and the explanation of the program.

  The program information PI [n] is described in HTML (Hyper Text Markup Language). However, the format of information described, the type of tags used, the order of description, and the like differ from broadcast station to broadcast station. The format conversion unit 21 converts the format of the acquired program guide 24 into a predetermined common format. The format conversion unit 21 has a plurality of conversion filters 25 corresponding to a plurality of types of formats. Each conversion filter 25 converts a corresponding format into a common format.

  The program table 26 thus obtained has a common format. Specifically, as shown in FIG. 4, the program table 26 includes a field 261 that describes a station ID (identifier) assigned to each broadcasting station, and a plurality of programs corresponding to programs scheduled to be broadcast from the broadcasting station. And a record 262.

  In each record 262, program information PI [n] of the corresponding program is registered. Specifically, program broadcast time and meta information are described. In this example, the broadcast start time begin [n] and the broadcast end time end [n] of the program are registered as the broadcast time. FIG. 5 shows an example of the program table 26.

  Referring to FIG. 3 again, a program guide database 28 is constructed in the web server 23. The program guide 26 converted into the common format is stored in the program guide database 28. The web server 23 reads the program guide 26 in response to a request from the PC 13 and transmits it to the PC 13.

  Next, the operation of the program guide supply server 12 will be described with reference to FIG.

  The acquisition unit 20 requests each broadcast station server 16 to transmit the program guide 24 (S101). Each broadcasting station server 16 accepts this request (S201), and transmits the program guide 24 to the program guide supply server 12 (S202). The acquisition unit 20 receives the program guide 24 (S102) and supplies it to the format conversion unit 21. The format conversion unit 21 converts the format of the program guide 24 into a common format, and creates the program guide 26 shown in FIGS. 4 and 5 (S103). Then, the created program guide 26 is stored in the program guide database 28 (S104). The program guide supply server performs the above-described operation every predetermined period (for example, every day), acquires the latest program guide 24, and creates the program guide 26.

[Configuration of air check device]
FIG. 7 shows a functional block diagram of the air check device. Referring to FIG. 7, air check device 80 includes a PC 13 and an FM tuner 14. The FM tuner 14 receives an FM broadcast. The PC 13 includes an ADC (Analog to Digital Converter) 31 that converts an analog signal output from the FM tuner 14 into a digital signal. The ADC 31 indicates, for example, a sound card. However, when the FM tuner 14 is a digital tuner that can output a digital signal, the PC 13 may not include the ADC 31. The PC 13 is also installed with a general-purpose MP3 (MPEG Audio Layer-3) encoder 32 and a general-purpose MP3 player 17 as well as an air check program, which will be described in detail later. A program guide database 37 is constructed. The air check program includes an index generation module 38, a web interface 39, an acquisition module 40, and a web browser 33. These details will be clarified in the following operation description.

  Next, the operation of the air check device 80 will be described.

  The FM tuner 14 and the PC 13 are always operating. Therefore, the FM tuner 14 always receives FM broadcasts, and the PC 13 records all received broadcast data in a storage medium (HDD 133).

  Referring to FIG. 8, the MP3 encoder 32 in the PC 13 is always operating, and encodes the digital broadcast data output from the FM tuner 14 and A / D converted into MP3 data (S401). In parallel with this, the web interface 39 also operates, and the MP3 data obtained by the MP3 encoder 32 is saved (recorded) in the MP3 database 34 as one MP3 file 42 every predetermined time (6 hours in this example) (S402). ). That is, the received broadcast data is divided into MP3 files and stored every predetermined time (6 hours).

  The web interface 39 also generates a recording situation management table 43 shown in FIG. 9 (S411) and stores it in the recording situation management database 35 (S412). Referring to FIG. 9, the recording status management table 43 includes a field 431 describing station IDs and a plurality of records 432 corresponding to a plurality of MP3 files 42. Each record 432 describes the recording start time, recording end time, and file name of the corresponding MP3 file 42. FIG. 10 shows an example of the recording status management table 43.

  The file name of the MP3 file 42 is set to, for example, “OOSAKA_20050522180000.MP3” (MP3 is an extension indicating the MP3 file 42) by combining the station ID and the recording start time. The recording start time corresponds to the broadcast start time of the MP3 file (broadcast data), and the recording end time corresponds to the broadcast end time of the MP3 file. In short, the recording time coincides with the broadcast time.

  In principle, FM broadcasts are recorded for 24 hours every day. However, because there is a case where a power failure occurs or the user turns off the power of the PC 13, all broadcast data is not necessarily saved as the MP3 file 42. For example, in FIG. 10, portions other than the hatched lines are not recorded.

  On the other hand, the index generation module 38 reads the MP3 file 42 from the MP3 database 34, generates an index file 44 based on the MP3 file 42 (S421), and stores it in the index database 36 (S422). In short, the index generation module 38 generates an index file 44 for each MP3 file.

  Specifically, as shown in FIG. 11, the index generation module 38 divides the MP3 file 42 into a plurality of sections 45 every predetermined time. In this example, since the MP3 file 42 for 6 hours is divided every second, 21600 (= 6 hours × 60 minutes × 60 seconds) sections 45 are obtained. Then, the index generation module 38 writes the start address of each section 45 in the index file 44 in order.

  FIG. 12 shows an example of the index file 44. The index file 44 has a field 441 describing station IDs and a plurality of records 442 corresponding to a plurality of sections 45. Each record 442 describes the start address of the corresponding section 45. In this example, the offset (relative address) from the head address of the MP3 file 42 is written as the start address. In FIG. 12, the elapsed time (seconds) from the beginning of the MP3 file 42 is shown, but this notation may be present, but not actually. This is because the elapsed time of each offset (record 442) can be calculated from the number of offsets before that offset.

  The file name of the index file 44 is also set to, for example, “OOSAKA_20050522180000.IDX” (IDX is an extension indicating the index file 44) by combining the same station ID and recording start time as the corresponding MP3 file 42.

[Broadcast data identification processing, playback processing and display processing]
Next, the broadcast data specifying process of the PC 13 will be described. In principle, the air check device 80 records all programs broadcast from the broadcasting station. Then, the broadcast data of the program selected by the user from the program guide is extracted from the MP3 file 42 and reproduced. However, as described above, not all broadcast data is recorded because of a power failure or the user turns off the PC 13, and some broadcast data of the program may not be recorded.

  When some broadcast data of a program is not recorded, the program is divided into a plurality of MP3 files and recorded. In the example shown in FIG. 13, the broadcast time zone of the program P10 is the time t10 to t11 (that is, the broadcast start time is t10 and the broadcast end time is t11), and the broadcast at the time t12 to t13 is caused for some reason. Data is not recorded. In this case, among the broadcast data of the program P10, the broadcast data from time t10 to time t12 is included in the MP3 file F10, and the broadcast data from time t13 to time t11 is included in another MP3 file F11 different from the MP3 file F10. It is. That is, the broadcast data of the program P10 spans two MP3 files F10 and F11.

  The air check device 80 according to the present embodiment extracts all the broadcast data of the program even if the broadcast data of the same program is divided into a plurality of files as in this example (broadcast data specifying process), The extracted broadcast data is continuously reproduced in the order of the broadcast time (recording time) (reproduction processing). Therefore, it is not necessary for the user to operate the reproduction instruction for each divided broadcast data. Further, the air check device 80 visually displays which time zone of the broadcast time of the program exists and which time zone of the broadcast data does not exist (display processing), and the user sees at a glance. To be able to grasp. Hereinafter, operations (broadcast data identification processing, reproduction processing, and display processing) of these air check devices 80 will be described.

[Broadcast data identification processing]
Referring to FIG. 14, the acquisition module 40 in the PC 13 acquires the program guide 26 of each broadcasting station from the program guide supply server 12 and stores it in the program guide database 37 (S500). The web browser 33 in the PC 13 displays the acquired program guide 26 on the display 134. For example, the program name is read from the meta information in each program information PI [n] in the program guide 26 and displayed on the display 134 together with the broadcast time. The web browser 33 receives designation of a program desired by the user from among a plurality of programs in the displayed program guide 26 (S501). The user designates a desired program name from the displayed program guide 26 using the input device 135 such as a mouse. At this time, the web browser 33 specifies a designated program (hereinafter referred to as a designated program) based on the program information PI [n] including the selected program name and the station ID in the program table 26 (S501). YES), a query is issued to the web interface 39 to read the broadcast data of the designated program.

  The web interface 39 receives the query, and from the program guide 26 stored in the program guide database 37, the program information PI [n] of the designated program and the station ID of the program guide 26 including the program information PI [n] Is read (S502). Subsequently, the web interface 39 refers to the recording situation management database 35 and reads the recording situation management table 43 having the same station ID as the station ID read in step S502 (S503).

  The web interface 39 identifies broadcast data of the designated program from among the plurality of MP3 files recorded in the read recording status management table 43 (S504 to S510). First, the web interface 39 sets the counter i = 1 (S504), and the MP3 file (hereinafter referred to as F [i]) recorded in the i-th = first (first) of the read recording status management table 43. = F1) The recording time (recording start time to recording end time) is read (S505). In the example of FIG. 10, the web interface 39 reads the recording time (recording start time to recording end time) of the MP3 file with the file name “OOSAKA_20050521000000” recorded at the top of the recording status management table 43. Then, it is determined whether or not the read recording time overlaps with the broadcast time in the program information PI [n] of the designated program (S506). If there is no overlap (NO in S506), the MP3 file F1 does not contain broadcast data of the designated program, so the counter i is incremented to i = 2 (S509), and the process returns to step S505.

  On the other hand, when the recording time of the MP3 file F1 overlaps with the broadcast time of the designated program (YES in S506), the broadcast having the broadcast time included in the broadcast time of the designated program among the broadcast data in the MP3 file F1. A data part is specified (S507). Specifically, the web interface 39 reads the index file 44 corresponding to the MP3 file F1. In this example, the corresponding index file 44 is specified by the file name. This is because, as described above, the file name of the MP3 file 42 and the file name of the corresponding index file 44 are the same except for the extension. The web interface 39 specifies the broadcast data portion within the broadcast time of the designated program based on the recording start time of the MP3 file F1 and the offset of the index file 44. Then, the web interface 39 registers information relating to the specified broadcast data part (hereinafter referred to as broadcast data specifying information) in the playlist shown in FIG. 15 (S508). Referring to FIG. 15, the broadcast data specifying information registered in the playlist includes the file name of the MP3 file including the specified broadcast data part, and the start offset and end offset of the specified broadcast data. The playlist is stored in the memory 132.

  The web interface 39 sequentially performs the operations of steps S505 to 509 on the plurality of MP3 files recorded in the recording status management table 43. Then, when the recording start time of the MP3 file Fi becomes later than the broadcast end time of the broadcast time of the designated program (YES in S510), the broadcast data specifying process is ended.

  By executing the above-described flow, when the broadcast data specifying information is registered in the playlist in step S508, the recording time (that is, corresponding to the broadcast time of the broadcast data portion) is registered in the playlist in order from the earliest. . An example of the playlist when the broadcast data identification process is completed is shown in FIG. As can be seen from the file name, broadcast data specifying information is registered in the playlist in order of the recording time of the broadcast data.

[Playback processing]
After completing the broadcast data specifying process, the air check device 80 executes a reproduction process. At this time, the air check device 80 extracts and reproduces the broadcast data portion specified by the broadcast data specifying information registered in the playlist. At this time, the broadcast data portion specified by the broadcast data specifying information in the playlist is continuously reproduced in the order from the earliest broadcast time.

  Referring to FIG. 17, first, the web interface 39 extracts a broadcast data portion based on broadcast data specifying information registered in the playlist (S601 and S602). Specifically, the count k is set to 1 (S601), and the broadcast data portion specified by the broadcast data specifying information recorded in the kth = first (top) of the playlist is extracted (S602). In the example of FIG. 16, the broadcast data portion corresponding to the end offset is extracted from the start offset of the MP3 file with the file name “OOSAKA_20050521000000”. Then, the extracted broadcast data part is transferred to the web browser 33. The web browser 33 activates the MP3 player and starts playing the broadcast data portion received from the web interface 39 (S603). When the reproduction is completed (YES in S604), the web browser 33 issues a query to the web interface 39 to pass the next broadcast data portion. The web interface 39 that has received the query increments the counter k to k = 2 (S605), and determines whether or not the kth = second broadcast data specifying information is registered in the playlist (step S605). S606). When the broadcast data specifying information is registered (YES in S606), the broadcast data portion specified by the registered broadcast data specifying information is extracted (S602) and passed to the web browser 33. In short, when a plurality of pieces of broadcast data specifying information are registered in the play list, the web interface 39 sequentially extracts the broadcast data in the order of the earliest recording time (broadcast time) and passes the information to the web browser 33. Thereby, even if the broadcast data of the designated program extends over a plurality of files, it can be reproduced continuously. If the result of determination in step S606 is that there is no kth recorded information (NO in S606), all broadcast data recorded in the playlist has been reproduced, and the reproduction process is terminated. When there is one piece of broadcast data specifying information registered in the playlist, that is, when broadcast data corresponding to the designated program is included in one MP3 file, the web browser 33 only has one piece of broadcast data. Play.

[Display processing]
The air check device 80 further allows the user to grasp at a glance which time zone of broadcast data in the designated program exists and which time zone of broadcast data does not exist. And the broadcast time of the specified broadcast data portion are displayed on the display 134 by a graph or the like.

  With reference to FIG. 18, the web interface 39 reads a playlist (S701), and specifies the broadcast time of each broadcast data portion specified by the broadcast data specifying information (S701 to S705). The web interface 39 sets the counter j = 1 (S702), and based on the file name of the MP3 file in the broadcast data specifying information recorded in the jth = first (first) of the playlist, The recording start time is specified (S703). In FIG. 15, the recording start time is specified as 0:00:00 from the last six digits of the file name “000000”. Next, the broadcast time of the broadcast data specified by the broadcast data specification information is specified based on the specified recording start time, start offset, and end offset. Specifically, the start time and end time of the broadcast data part are specified. The specified start time and end time are stored in the memory 132. After storing, the counter j is incremented to j = 2 (S704), and the broadcast time (start time and end time) of the broadcast data portion is specified based on the broadcast data specifying information recorded second in the playlist. To do. The web interface 39 performs the process of step S703 on all broadcast data specifying information recorded in the playlist (S705). After executing the process of step S703 for all broadcast data specifying information (NO in S705), the web interface 39 is based on the broadcast time (start time and end time) of each broadcast data stored in the memory 132. A graph image is created (S706). FIG. 19 shows an example of the created graph image. In this example, a progress bar 800 is employed as the graph image. Specifically, the length direction of the progress bar 800 is taken as a time axis, and the broadcast time (program scale) of the designated program, the time zone in which broadcast data exists, and the time zone in which broadcast data does not exist on the same time axis Is illustrated. The length L of the progress bar 800 indicates the length of the designated program broadcast time (10:30 to 12:00 in this example). Then, in the progress bar 800, the broadcast time part (T2 and T4) of each broadcast data part specified in step S703 is specified, and the part of the time zone (T1 and T3) other than T2 and T4 is visually The images can be distinguished from each other. In this example, in the progress bar 800, the time zones T2 and T4 in which broadcast data exists are drawn in a predetermined color, and the time zones T1 and T3 in which no broadcast data exist are drawn in a color different from t2 and T4. . Note that a graph image may be created by a method other than this example so that the time zones T2 and T4 in which broadcast data exists can be known. For example, as shown in FIG. 20, using the same time axis, a bar 900 indicating the broadcast time of the designated program and bars 901 and 902 indicating the broadcast time of the specified broadcast data portion are displayed on the display 134. As described above, image data may be created. Further, as shown in FIG. 21, data may be created so that the broadcast time of the designated program and the broadcast time of the specified broadcast data portion are displayed as character image data. In the following description, it is assumed that the PC 13 has created the image data shown in FIG.

  The web interface 39 passes the created image data of the progress bar 800 to the web browser 33. The web browser 33 receives the image data and displays it on the display 134 as a graph. That is, the progress bar 800 shown in FIG. 19 is displayed (S707). When the web browser 33 reproduces the broadcast data while displaying the progress bar 800 on the display 134, the pointer 950 indicating the reproduction position of the broadcast data is displayed on the progress bar 800 as shown in FIG. Thus, the user can visually confirm at a glance which time zone broadcast data exists and which time zone broadcast data does not exist in the entire broadcast time of the designated program.

  In the above description, the progress bar image 800 is used to visually display the time zone in which the broadcast data exists in the designated program in distinction from the time zone in which the broadcast data does not exist. You may display visually using the graph image.

  In the above-described embodiment, the broadcast time of the program guide 26 includes the broadcast start time and the broadcast end time. However, only the broadcast start time may be included as the broadcast time. In this case, the broadcast time of the program P [n] is from the broadcast start time of the program P [n] to the broadcast start time of the program P [n + 1].

  In the above-described embodiment, the air check device 80 acquires the program guide from the program guide supply server 12, but may acquire the program guide directly from the broadcast station server 16.

  While the embodiments of the present invention have been described above, the above-described embodiments are merely examples for carrying out the present invention. Therefore, the present invention is not limited to the above-described embodiment, and can be implemented by appropriately modifying the above-described embodiment without departing from the spirit thereof.
