Description

Digital playback device and method for continuing to play interrupted TV programs

technical field

The invention relates to an audio and video playing device and method in the field of broadcasting and television and a television set including the device, in particular to a digital playing device and method capable of continuously playing interrupted TV programs.

technical background

With the continuous development of audio and video technology and broadcast communication technology, people can obtain more and more audio and video programs. Numerous audio and video programs are broadcasted by operators in various ways. In the field of television, as the number of channels that TV sets can receive increases, many popular TV programs will be broadcast on multiple TV channels during the same period, that is, the program content is the same, but the broadcast time is either the same or There is a certain time difference. In this way, the user can watch the same TV program or related TV programs through the same or different channels in multiple time periods, which greatly facilitates the viewing of the user.

When watching a program, the user may often have to interrupt the program in the channel currently being watched for various reasons, and perform other operations (such as pausing, changing channels, shutting down and sleeping). Since TV shows are on the air, when you next watch the channel, the previously interrupted shows will have been missed. For a movie, the entire movie may be missed, and for a TV series, the entire plot may be incomplete due to missing a highlight, thereby affecting the viewing of the user. This is highly undesirable for the user. Therefore hope that there is a kind of TV set that can provide a kind of exciting TV program that can be played continuously because of interruption before when starting up next time.

Methods already exist to help a user continue watching a television program where it was interrupted.

Patent Document 1 discloses a digital broadcast receiver capable of continuing to play interrupted programs. The following technical solution is disclosed in this patent document: supported by the TV operator, the TV content is played in a specific way known in advance by the digital broadcast receiver. For example, play the same content on multiple channels with a certain delay, such as 15 minutes after the first channel broadcasts, the second channel starts broadcasting the same program content, or multiple channels Play the same content with mutual delay. When the user interrupts the program he watched for some reason and comes back to watch TV after a period of time, the same program content delayed in other channels may be just right, or slightly different. In a short time, it can be connected with the content of the watched program at the time of interruption. At this time, the system will judge and detect the most suitable channel, that is, the channel whose delay time is greater than the interruption time and the difference between the delay time and the interruption time is the smallest. Moreover, when the user ends the interruption and re-watches the TV, it can automatically switch to the detected best program channel. The complete program content of the interrupted program is provided to the user, which is convenient for the user to watch.

Patent Document 1: Japanese Patent Laid-Open No. 9-261548, "Digital Broadcasting Receiver", the applicant is Sanyo Electric Co., Ltd.

The method and playback receiving device disclosed in Patent Document 1 can help the user continue to watch the previously interrupted TV program under certain specific conditions without storing the program content locally. However, the use of this method requires certain restrictions: 1) It needs to be supported by the TV operator from the broadcast of the TV signal, that is, the same program is broadcast on multiple channels according to a certain time difference. For the television terminal, these multiple channels and the broadcast time difference between the multiple channels need to be known in advance. If the operator's support is not obtained, or the schedule of broadcasting the program changes temporarily, the TV terminal cannot allow the user to continue watching the previously interrupted TV program. 2) The continuation of the interrupted program realized by this method has requirements for the interrupted time, that is, in the above-mentioned multiple related channels that play the same content, the interrupted time must be less than the maximum time difference between the two channels, and the interrupted program will be It is possible to find the corresponding channel among multiple channels, and then continue playing the interrupted program. If the interruption time is too long and is greater than the maximum time difference of playing the same content in multiple channels predicted by the TV terminal, then no target channel can be found in these channels that can continue to play the interrupted program, so that the continuation of the interrupted program cannot be realized. .

Therefore, there is a need for a flexible and convenient method and device for continuing to play interrupted TV programs without the support of operators.

Detailed ways

The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

It should be noted that in the present invention, for the convenience of explanation, we choose digital TV as the platform and take the interruption of digital TV programs as an example to introduce the specific implementation process of the present invention. However, those skilled in the art should understand that the present invention is not limited to the field of television broadcasting, and the implementation occasions are not limited to continuing playing after program content is interrupted.

In the present invention, when the current TV program is interrupted, the information related to the interrupted current TV program is recorded, such as the program viewing information of the interrupted program, and the state information when the program is interrupted; Information related to TV programs, search for interrupted TV programs at designated locations, such as searching electronic program guides (EPG), the Internet and content servers, etc., to obtain the broadcast time and channel of programs that are the same as or related to interrupted programs in the near future information; the search results (program viewing information and downloaded target program content) are stored; when the user starts watching TV again, the digital playback device can be automatically switched to the corresponding channel according to the search results, and the previously interrupted program can be continued. Prompt the stored search results to the user, that is, to prompt the user with the broadcast program rating information of the follow-up content at the interruption point of the interrupted program, or the local download information; when the user chooses to continue playing the interrupted TV program, continue to play the interrupted TV program programme. The program viewing information in the present invention includes all related information used to describe program attribute information and location information.

FIG. 1 is a schematic structural diagram of the digital playback device of the present invention. The device can be a cable digital TV set, or an audio and video playback device with audio and video content playback function, such as a set-top box, a multimedia computer, an Internet radio, and the like. The digital playback device in the figure includes a user interface unit 1, which can respond to the user's control through the remote controller, and receive and recognize user input commands; a tuner (Tuner) unit 2 is responsible for receiving digital TV signals and decoding the received signals. Tone, convert the RF signal into a Transport Stream (TS). The tuner unit may be a digital TV tuner, or a TV receiver, network device, audio and video receiver, etc., which can be used to receive program information and select program content. The transport code stream output from the tuner unit is decoded by the decoder, and then the code stream signal is demultiplexed by the demultiplexing unit. The digital playback device also includes a recording unit 3 for digital TV, which can be used for information storage, program content storage, and operations such as adding, modifying, and deleting stored content. Its form can be a memory chip on the main board, or a built-in or external storage unit connected to the TV, such as a hard disk, SD card, SDRAM, etc. The control unit 4 may be the control hardware or corresponding control software of the main board in the digital playback device and the peripheral components connected to it. According to the instructions received by the user interface unit, the control unit 4 controls the tuner unit to work in a specified manner, controls the data exchange with the recording unit, and controls the correct playback of multimedia information such as audio, video and text in the program playback unit. After receiving the user's instruction to interrupt the program, the control unit 4 can search for the interrupted TV program at a designated location according to the program viewing information related to the interrupted current TV program recorded by the recording unit 3, and store the search results In recording unit 3. When the interruption ends, the control unit 4 can control the information prompting unit to prompt the user with the search results stored in the recording unit. The digital broadcasting device also includes a program playing unit 5 for playing the TV program received by the tuner unit, and continuing to play the interrupted TV program when the user chooses to continue playing the interrupted TV program. The program playing unit 5 includes a video unit, which is responsible for displaying digital TV program pictures and text information; an audio unit is responsible for sound synthesis and output; a program information unit is responsible for presenting relevant information in the TS code stream to users. As shown in Figure 1, the digital playback device in this embodiment may also include other related components for communication, storage, control, playback, etc., such as network interface, SD card reader, USB interface, etc., these components also All are controlled by the control unit 4 and work together normally in the digital playback device.

When the user interrupts the program channel currently being watched for some reason, and then continues to watch the channel again, the user hopes that the interrupted program can continue from the last interruption point after a period of interruption. The continuation of the missed program content connection. The above-mentioned digital playback device of the present invention records program interruption points, searches all channels or searches the Internet and content servers, provides users with desired content in the most convenient and quickest way, and realizes continuous playback of interrupted programs.

Fig. 2 describes the processing procedure of the digital playback device of the present invention when the program is interrupted by the user. When the user has performed relevant operations on the program being watched (such as the user turning off the machine), so that the current program is forced to be interrupted (S201), the control unit 4 obtains the program viewing information (S202) of the interrupted program, such as the interrupted time, the name of the interrupted program , how long the program has not finished broadcasting when it is interrupted, etc. Afterwards, the control unit 4 obtains from the recording unit 3 the user's prior arrangement of various processing options for the interrupted program (S203). The configuration options are shown in Figure 5. Judging whether to automatically save the program viewing information (S204), if in the configuration options as shown in Figure 5, the configuration of this option is "yes", then it is determined that the interrupted program viewing information is automatically saved by the recording unit by the control unit 4 ( S206); if the option is "No", then do not save; if the configuration of the option is "prompt", then the user is prompted, and the user decides whether to save the program viewing information of the currently interrupted program (S205). If the user determines that it is necessary to save, the control unit 4 controls the recording unit 3 to save the viewing information of the interrupted program in the recording unit 3 (S206). The purpose of recording the viewing information of the interrupted program is to provide the user with the most convenient and quick continuation of the same program content or related content when viewing next time by searching or downloading. Therefore, after the interrupted program viewing information is stored, a search for the same program viewing information or download information is carried out according to the recorded program viewing information (S207), and a search for related program viewing information or download information is carried out according to the recorded program viewing information (S208) . Then the search result is recorded by the recording unit (S209). Next, the download option is judged (S210), if it needs to be downloaded (that is, in the configuration options shown in Figure 5, the configuration of this option is "Yes"), then continue to judge whether to download the entire program (that is, including the program before the interruption) Have viewed and missed program content after interruption), or only download the viewing content (S211) missed due to interruption (for example, in the configuration options shown in Figure 5, the configuration of this option is "partial program"). The above steps of selecting and downloading some programs can reduce network traffic, storage space and downloading time, so that users do not need to pay a relatively high network fee due to excessive traffic, thereby obtaining speed and economic benefits. From the downloaded address obtained by searching, the program content of the specified part of the specified program is downloaded and recorded by the recording unit 3 (S212). Then record information such as the downloaded state information, the location of the local storage, etc. as the download information in the recording unit (S213). If the user does not record the viewing information of the interrupted program or download it, the processing flow is directly ended (S214).

Fig. 3 is a flow chart of the method when the digital playback device of the present invention plays again. When the digital playback device starts playing again (S301), at first the control unit 4 reads the user's configuration options (S302) from the recording unit 3, such as configuration options such as reminder mode and update mode (configured as shown in Figure 5 In the options, the configuration of the reminder method option is "Yes", and the configuration of the update method option is "Yes"). According to the time of the last search and the restarted playback time obtained from the search, the search results are updated (S303) to delete invalid or invalid search records. Read the program viewing information records of many programs that have been updated, including reading the program viewing information records of interrupted programs and the results of the search (S304). If the user configures automatic switching and prompt switching to prompt the user to choose (S305), then when the interrupted program can be played continuously, the user can choose whether to switch (S306) through screen prompts. If the configuration option is automatic switching, then when the interrupted program can be played continuously, it will automatically switch to the target channel to continue playing the previously interrupted program (S307).

In the recording unit 3, a plurality of records of viewing information of the interrupted program are also recorded, mainly including: content information of the interrupted program, such as program name, etc.; location information of the interrupted program, such as episode information, channel to which it belongs, start time, End time, etc.; interruption information, such as interruption time, etc.; sorting information in multiple interruption records, such as time sequence information, etc.; reminder information at the end of interruption, such as power-on reminder, association reminder, etc.; search for related programs of interrupted programs Information, such as search location information, etc.; and download and save information on search results, such as automatic download, download location, etc.

FIG. 4 is an example of program viewing information recorded by a recording unit according to an embodiment of the present invention. In Figure 4 only 3 records are listed for illustration. For each record, the viewing information of the interrupted program includes the interrupted time of the program, the channel when interrupted, the title of the program, the broadcast time length of the program, the interrupted position (the time when the interrupted program starts to play, that is, the program segment has been seen length of time period). For types such as series or series, the content of the program is also positioned by the location of the episode. In addition, the recording unit also records some configuration options for the recording of this interrupted program, such as whether to prompt on the screen when the continuation playback can start, that is, the point prompt option in Figure 4 . Also records the search location, including whether to search EPG, whether to search the Internet; information about downloading, including whether to download the entire program file, or only download the program segment specified by the user, usually the content of the missed program segment; and save locally after downloading location etc. For example, for the first record, the 20th episode of the "Dream of Red Mansions" TV series was interrupted by the user when it was played on Channel-1 at 19:10:00 on September 1, 2007. At this time, the program was 60 minutes long. Only watched it for 10 minutes. The control unit needs to search the EPG and the Internet according to these information, then download the entire 60-minute program, save it in the local C:\hlm20.avi file, and give the user relevant prompts when the program can be played.

Figure 5 shows various options configured by the user, which can be the default configuration here, or can be configured individually for each record. The configuration options are: when the associated program can be played, whether to prompt the associated program; download the whole program or a program segment; whether the search process should be performed when the device is turned on or turned off, and in the background when the digital playback device is running search etc. Other options mainly include a reminder method, a switching method, a search location, etc., as shown in FIG. 5 , and will not be described here one by one.

The device and method for supporting multiple conditional access modules of the present invention are described above with examples. However, those skilled in the art should understand that the above-mentioned embodiments are only for illustration and not for limiting the present invention. For example, there are many ways to interrupt the above programs. In addition to the shutdown interruption shown in this embodiment, the interruption methods can also be pause, sleep, channel switching, user-controlled interruption, and so on. Similarly, there can be many ways to restart the interrupt or continue the interrupted program corresponding to the interrupted mode. In addition to restarting the program shown in FIG. Play interrupted programs, etc.

Fig. 6 shows an example of a screen prompt. For example, when the user watches TV again, according to the search results, the 20th episode of the program "Dream of Red Mansions" that the user watched on Channel-1 before being interrupted will be played on Channel-2 to the point where the previous viewing was interrupted. There are 30 seconds left before the last interruption point, and the program can be completely connected with the last interrupted program. Then, the screen reminds the user whether to jump to the Channel-2 channel to continue watching the program that was interrupted last time. If the user chooses to jump now, the control unit 4 controls the tuner 1 to switch the channel to Channel-2, and the program content of Channel-2 is decoded and demultiplexed by the decoder and demultiplexing unit, and the control unit 4 controls Next, the content of the target program is played to the user through the program playing unit, so as to realize the continuation of the interrupted program.

FIG. 6 is just an example showing that the continuation of the interrupted program is realized through the prompt on the screen. In practical applications, there may be many situations: for example, after the interruption is over, the most matching program source in the search results is automatically called, and the target program source is automatically switched to realize the automatic continuation of the interrupted program. It is also possible to automatically switch to the target program source for playback when the playback position of the target program source just matches the interrupt position of the interrupted program source. It is also possible to automatically pass the search results through the information prompt unit when the interruption is over, such as when starting up, to remind the user that there is a program source that can continue to play the previous interrupted program, and the user can choose whether to jump to the target program source to continue playing the interrupted program , or according to the user's choice, the playback of the interrupted program can be abandoned. For the contents whose boot prompt option is "No", the system will not actively prompt the user, but the user will actively query the search results of the interrupted program rating information through the user interaction unit to decide whether to enable the interrupted program to continue the playback process . Due to the broadcasting method of digital TV, when starting up or interrupting and restarting, the playback time of the target program source searched cannot completely match the current time, and there may be a certain time difference. At this time, if jumping to the target program source, there will be problems such as waiting for a long time, which will interfere with the viewing of the user. Therefore, the reminding method can also remind the user that the previous interrupted program can now continue to be played on other channels through the information prompt unit at the moment when the target program source and the interruption point of the interrupted program are about to or just match. Whether to continue playing the interrupted program is judged by prompting and user selection. Similarly, for the associated reminding option, the reminding methods can also be the above multiple.

Fig. 7 shows an example of the specific processing procedure of the search. If the search time option configured in FIG. 5 is power-off search, then when the user turns off the TV (display sleep) (S701), the control unit 4 reads the user configuration file from the recording unit to obtain the user configuration. Then search the records of the interrupted program viewing information shown in FIG. 4 one by one (S703). Read the search location information in the configuration option of each record as shown in FIG. 4 , and if the search location information is Internet search (S704), perform Internet search (S705). The search method may be based on keyword matching such as program name, episode location information, and the like. Meanwhile, if the search location information also includes the need to search for the EPG (S706), then perform the search for the EPG (S707). The results of searching for a plurality of databases are then recorded in the recording unit (S708). If the search result is obtained by Internet search, and it is judged that there is an address of an effective target program file that can be downloaded in the search result and the configuration option requires downloading of the program content (S709), then from the effective target address according to the configuration of the download option The program content of the target file is downloaded, and the downloaded program content is stored in the recording unit. After it is judged that the above operations are performed for each record of the interrupted program in the stored multiple records (S711), the entire search process is completed (S712).

Fig. 7 only illustrates the specific processing procedure of the search. However, in practical applications, there may be multiple ways to search for programs. For example, the search time may be search when power off, search when power on, sleep search, and search during program viewing. The search location can be an EPG, the Internet, and a content server, among others. The search method may be the matching of the name of the interrupted program, the matching of the episode corresponding to the program, and the like. Matching items need to ensure the correspondence in broadcast time, that is, the broadcast time of the target program source needs to be after the search time, because the past program rating information is no longer valid.

Fig. 8 is a flow chart of processing after the digital playback device of the present invention is turned on. According to user configuration, the digital playback device searches and downloads the interrupted program when it is turned off as shown in Figure 7, obtains available target information or downloaded files, and stores them in the recording unit. After the user turns on the device next time, some recorded program broadcast information may be invalid, for example, the program has already been broadcast before the user turns on the device. Therefore, it is necessary to update the previously recorded information. After starting up (S801), at first read configuration file, obtain user's configuration (S802), if user's configuration requires starting up and carry out automatic update (S803), then need to read the information (S804 ), and possibly multiple target broadcast times or target program files corresponding to each interrupted program. Compare the current time with each target broadcast time (S805), if the current target broadcast time has expired (S806), delete the expired record, or mark it as invalid (S807). If there is no valid target broadcast time corresponding to an interrupted program in the search record (S808), search the search location (such as EPG, Internet, etc.) again, and save the search result (S809). If the configuration option indicates that the user needs to be prompted when starting up (S810), then a screen prompt similar to that shown in FIG. 6 is performed (S811). Finally, the user decides the next operation according to the prompt on the screen, and ends the process (S812).

Fig. 9 is a schematic diagram of the same program search results as "Dream of Red Mansions Episode 20" according to the embodiment of the present invention. Corresponding to the first recorded information in Figure 4, there are 3 search results for the 20th episode of "A Dream of Red Mansions" in Figure 9. The search location is EPG and the Internet, and the search result of EPG indicates the start time and start channel of the same program that can be received by broadcasting. Then when the user's viewing time reaches the start time of the searched record next time, and broadcasts the content at the position watched when the last time was interrupted, for example, at 10 minutes from the last time, you can follow the reminder method to appear The hint shown in Figure 6: there is a program starting from the 10th minute of the 20th episode of the interrupted program "Dream of Red Mansions" on Channel-2. Then the user chooses whether to jump or not.

Fig. 10 is a schematic diagram of search results of programs related to "Dream of Red Mansions Episode 20" according to an embodiment of the present invention. For example, the last interrupted program is episode 20 of "Dream of Red Mansions", according to the associated search configuration, you can search for related episodes before and after episodes 21, 22, and 23. As shown in Figure 10, for example, for the content of the 23rd episode, the content of this episode is downloaded according to the download option configured by the user, and the saving path is the C:\hlm23.avi file. When the user turns on the computer next time or wants to watch the 23 episodes, the file can be played locally directly.

It can be seen from the above description that the present invention obtains the target broadcast time and location by searching the interrupted program, and can download the target file to the local through the Internet, thereby expanding the ability to continue playing the interrupted program, which greatly facilitates users viewing.

Fig. 11 is a flow chart of program file download processing according to an embodiment of the present invention. As shown in FIG. 11 , it is first necessary to acquire the user's configuration of download options (S1102), and then read the search results (S1103). If the user configuration requires the program to be downloaded (S1104), check whether there is an effective download address in the searched record (S1105). Because some download addresses may require special users, although ordinary users can see the address, they cannot download without permission, so it is necessary to check the validity of the address. If all addresses are invalid, a download error is displayed (S1106). If it is possible to download, perform all downloads or only download segments according to user configuration (S1107). Fragment downloading can not only save space but also reduce traffic and user traffic charges. Then, store the downloaded result (S1109), and update the search result (S1110), indicating that the program has been downloaded locally. Then, the local program source can be flexibly used for playback during continuation playback.

The digital playback device and method for continuously playing interrupted TV programs of the present invention can not only be applied in the field of TV, but also can be widely used in IPTV (Internet TV) or broadcasting. For example, many radio stations currently provide timely traffic information. If the user only selects a TV station, the time of the traffic information broadcast regularly or randomly may be relatively short, and the road sections reported are limited, which cannot satisfy the real-time traffic information of the road sections that the user wants to know in many cases. In fact, there may be a plurality of radio stations continuously broadcasting traffic information of a plurality of road sections at different times. Then, if multiple radio stations can be fully utilized, rich real-time traffic information can be provided, and the time and area coverage is large. Therefore, the method of the present invention can be utilized to obtain the broadcasting time of road condition information of multiple radio stations in different times by searching and recording, and then prompt or automatically select a channel to perform rich programs of the same type combined by multiple radio stations. Play to meet user needs.

The description of the disclosed embodiments provided above is provided to enable any person skilled in the art to make and use the invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit and scope of the invention. Thus, the present invention is not limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
