Description

  The present invention relates to a broadcast wave receiver such as a digital television receiver, and more particularly to a control method for controlling screen display.

  In digital television broadcasting, the main information is program data (video / audio data that viewers normally view when selecting a channel) and emergency information such as caption information accompanying the program and emergency broadcast information not accompanying the program. It is possible to multiplex and transmit character data and program explanation data (program related information) that describes the attributes and contents of the program into one transport stream (TS). The multiplexing structure to TS is defined in ISO / IEC IS 13818-1, International Standard, MPEG-2 Systems.

  The digital television receiver that receives and reproduces the multiplexed TS receives the character data and the received program explanation data by graphic processing according to the instructions of the viewer and the preset settings. Some video data can be multiplexed and displayed on the video.

  Hereinafter, the operation of the conventional digital television receiver 700 will be briefly described with reference to FIG. FIG. 7 is a block diagram showing the configuration of a conventional digital television receiver.

  In FIG. 7, a digital television receiver 700 includes a broadcast receiving unit 701, a channel selecting unit 702, a signal separating unit 703, an audio data processing unit 704, a video data processing unit 705, a character data processing unit 706, an audio signal output unit 707, a video. A signal output unit 708, a graphic processing unit 709, a user operation interface unit (user operation I / F unit) 710, and a program explanation data processing unit 711 are configured.

  The broadcast receiving unit 701 receives an RF signal (broadcast signal), demodulates it into a digital signal, outputs a control signal to the channel selection unit 702, and outputs a demodulated signal to the signal separation unit 703.

  The user operation I / F unit 710 receives an instruction from the user using a remote controller or the like, and outputs instruction information from the user to the channel selection unit 702, the character data processing unit 706, the program explanation data processing unit 711, and the like.

  The channel selection unit 702 is defined in the TS to specify information to be processed using the instruction information from the user input from the user operation I / F unit 710 and the control signal input from the broadcast reception unit 701. Identification information is specified, and the specified identification information is output to the signal separation unit 703.

  The signal separation unit 703 separates an audio signal, a video signal, character data, program description data, and the like to be processed from the demodulated signal output from the broadcast reception unit 701 using the identification information output from the channel selection unit 702. The extracted data are output to the audio data processing unit 704, the video data processing unit 705, the character data processing unit 706, and the program explanation data processing unit 711, respectively.

  The audio data processing unit 704 decodes the audio data input from the signal separation unit 703 into an analog audio signal and outputs the analog audio signal to the audio signal output unit 707. The audio signal output unit 707 is input from the audio data processing unit 704. The analog audio signal is output as audio.

  The video data processing unit 705 decodes the video data input from the signal separation unit 703 into an analog video signal and outputs the analog video signal to the video signal output unit 708.

  In addition, the character data processing unit 706 converts the character data input from the signal separation unit 703 into graphic drawing information according to user instruction information from the user operation I / F unit 710 and outputs the graphic drawing information to the graphic processing unit 709. The program explanation data processing unit 711 converts the program explanation data input from the signal separation unit 703 into graphic drawing information according to user operation information from the user operation I / F unit 710 and outputs the graphic drawing information to the graphic processing unit 709.

  The graphic processing unit 709 processes the graphic drawing information input from the character data processing unit 706 and the program explanation data processing unit 711 to generate a graphic signal, and outputs the graphic signal to the video signal output unit 708.

  The video signal output unit 708 multiplexes the video signal input from the video data processing unit 705 and the graphic signal input from the graphic processing unit 709 in accordance with a user instruction or a predetermined setting. Display as video.

  FIG. 8 is a diagram showing an image display image in the digital television receiver, but in the conventional digital television receiver 700, as shown in FIG. Only the broadcast program video (a) to be displayed is displayed on the full screen (A) without multiplexing other video, or the broadcast program video (a) and the data broadcast as shown in FIG. Whether to multiplex and display other video (b) such as a graphic in the above or a graphic based on an electronic program guide composed of program explanation data is fixedly set or determined by a clear instruction from the viewer Is done. That is, when data broadcasting is received, multiplexed display is always performed, or whether to perform multiplexed display or not depending on whether or not a predetermined remote control button (usually “d” button) is operated is switched. . Also, with regard to the multiplexed display of the electronic program guide, whether to perform the multiplexed display is switched depending on whether or not a predetermined remote control button is operated.

  On the other hand, with the recent development of communication technology, it has become possible to acquire and view video / audio data through communication. Unlike broadcasts that allow viewers to watch and record only programs that have been determined in advance by the broadcast station when viewers watch the programs, they can select and watch as much as they like whenever they want. A video / audio service (program distribution service) that provides an environment capable of recording using communication has been started.

  Video / audio viewing using such a program distribution service will greatly increase the choice and enjoyment for viewers, but the choice of such a program distribution service will greatly expand. In addition, the convenience of the selection method is important.

  For example, when a viewer selects a desired program from among thousands or tens of thousands of programs arranged in alphabetical order, the viewer clearly remembers the program name, and clearly This method is effective only when the user wants to watch the program. When the viewer remembers the program name or when the program that the user wants to watch clearly has not been determined, the selection method is very difficult to use. In such a case, as a relatively suitable selection method, there are a method of selecting from programs arranged according to program genre (classification according to contents) and popularity, and a method of recommending a program selected by a service provider. is there.

  Further, as one method for promoting the use of the program distribution service, a graphic (program selection screen) for selecting a program provided by the program distribution service is displayed by being multiplexed with the broadcast program video, It may be possible to select a program provided by a program distribution service while viewing a broadcast program. Note that switching of multiplexed display of such graphics (program selection screen) is determined by whether or not a predetermined remote control button is operated by the viewer, as in the case of multiplexed display with graphics in the data broadcasting described above. It is common.

  On the other hand, when switching between full screen display of broadcast program video and multiplexed display with other graphics is determined by the operation of the remote control button by the viewer, in many cases the full screen display of broadcast program video After viewing, it is necessary for the viewer to have a motivation to operate the remote control button again to perform multiplexed display. If there is no trigger, the viewer will not have the opportunity to operate the remote control button corresponding to the multiplexed display, and the effect for promoting the use of the program distribution service will be limited.

  As a specific method for encouraging the viewer to use the program distribution service, when the program selection screen of the program distribution service is multiplexed with a broadcast program video, It is conceivable to recommend a program of a program distribution service having contents related to the program video. In this case, since the program of the program distribution service recommended for the viewer is predicted to match the viewer's preference and interest, it can be further expected as an effect for promoting the use of the program distribution service.

  More specifically, each news program produced by composing multiple items of several minutes each contains a wealth of fresh information based on facts, and a program distribution service program related to those news programs. It is considered that there is a high demand from viewers to deepen their knowledge.

  Therefore, it is useful to automatically switch to the graphic multiplex display for selecting the program of the recommended program distribution service when the viewer is watching the news broadcast program. As described above, the following two methods (1) and (2) can be cited as methods for automatically switching the display content in accordance with the content of the broadcast program.

(1) Method of learning the operation history of the viewer and judging based on the learning result (2) Method of judging based on the genre information for the broadcast program being watched A method applying the technology is disclosed. As the method (2), a method using genre information and sub-genre information defined in ARIB (Radio Industry Association) in Non-Patent Document 1 is disclosed.

  Subsequently, the recommended screen transition control unit 112 uses the specific program management table shown in FIG. 4 held by itself to determine which program is being viewed based on the program related information acquired from the program explanation data processing unit 111. It is determined whether or not the program is a specific program management target (S202).

  In the specific program management table shown in FIG. 4, a program “Wide A” broadcast on channel X from 17:00 to 18:00 on Wednesday, and broadcast on channel Y from 16:50 to 17:00 on Friday. The program “Evening News” is registered as a program subject to specific program management.

  In addition, a program to be managed by a specific program includes a program whose multiplexed display setting is a target for non-multiplexed display (for example, a program belonging to the group of the specific program A), such as a program name: “Evening News”. The program name: “Wide A” is classified and registered into two types of groups, such as those for which the multiplexed display setting is the target of multiplexed display (for example, those belonging to the group of the specific program B). Therefore, programs that are not described in the specific program management table are handled as programs that are not managed by the specific program.

  If it is determined in step S202 that the program being viewed is not a specific program management target (No in step S202), the recommended screen transition control unit 112 uses the genre determination table shown in FIG. Then, it is determined whether or not the genre (sub-genre) of the program being viewed is an object of automatic switching to multiplexed display (S203).

  In the genre determination table shown in FIG. 3, “news / report (regular / comprehensive)”, “sports (sports news)”, “sports (baseball)”, “music (songs / enka)” and “information” / Wide show (program introduction / notification) ”is registered as a target for automatic switching to multiplexed display, that is, a genre (sub-genre) to be automatically switched.

  In addition, although the automatic switching setting is not targeted, the genre (sub-genre) other than the above that is intentionally registered in the genre determination table can be viewed by the viewer through the user operation I / F 110 or the like. When setting automatic switching of (sub genre), it was registered assuming that it has a function that enables easy setting change by selecting either “target” or “non-target” Is.

  For a genre (sub-genre) not registered in the genre determination table, the viewer selects a genre (sub-genre) and additionally registers it in the genre determination table, or a genre (sub-genre) other than the above It is unregistered assuming that it has a function that can be set as.

  If it is determined in step S203 that the genre (sub-genre) of the program being viewed is not an automatic switching target (No in step S203), the recommended screen transition control unit 112 recommends the recommended information acquisition / processing unit 113. Is instructed to cancel the multiplexed display (S204).

  On the other hand, if it is determined in step S203 that the genre (sub-genre) of the program being viewed is an automatic switching target (Yes in step S203), the recommended screen transition control unit 112 performs the program explanation data processing. It is determined whether or not the broadcast time of the program being viewed input from the unit 111 is shorter than a predetermined time set in advance (S205).

  This predetermined time can be changed through the user operation I / F unit 110. Further, the predetermined time can be set to a different value depending on the channel, time zone, day of the week, etc., so that it becomes possible to control in more detail.

  If it is determined in step S205 that the broadcast time of the program being viewed is shorter than a predetermined time set in advance (Yes in step S205), the recommended screen transition control unit 112 acquires recommended information. When the unit 113 is instructed to perform multiplexed display (S206) and it is determined that the broadcast time of the program being viewed is not shorter than a predetermined time set in advance (in the case of No in step S205). The recommendation screen transition control unit 112 instructs the recommendation information acquisition / processing unit 113 to cancel the multiplexed display (S207).

  Subsequently, returning to step S202, when it is determined that the program being viewed is a specific program management target (Yes in step S202), the recommended screen transition control unit 112 performs the specific program management shown in FIG. Referring to the table, it is determined whether or not the program being viewed is set to multiplex display (S208).

  If it is determined in step S208 that the program being viewed is set to be multiplexed display (Yes in step S208), the recommendation screen transition control unit 112 sends the recommendation information acquisition / processing unit 113 a request. If it is instructed to perform multiplexed display (S209) and it is determined that the program being viewed is not set for multiplexed display (No in step S208), the recommended screen transition control unit 112 instructs the recommended information acquisition / processing unit 113 to cancel the multiplexed display (S210).

  In the first embodiment of the present invention, the case where the broadcast receiving unit 101 receives a broadcast wave has been described as an example. However, the present invention is not limited to this. For example, an IP (Internet Protocol) communication path is used. It may be one that receives multicast communication. In this case, the broadcast receiving unit 101 needs to have a receiving function in IP communication, but has both a receiving function in IP communication and a broadcast wave receiving function so that a program can be received from either of them. It doesn't matter.

  In the first embodiment of the present invention, the information multiplexing method has been described by taking TS widely used for digital broadcasting as an example. However, the present invention is not limited to this. For example, PS (Program Stream) is used. There may be other multiplexing methods.

  In the first embodiment of the present invention, the digital television receiver 100 is described as an example of the broadcast wave receiver. However, the present invention is not limited to this. For example, an analog television receiver may be used. . It can be easily inferred that analog television receivers can also process information transmitted by multiplexing signals using a similar method.

  In the first embodiment of the present invention, the program recommended by the program distribution service has been described by taking content mainly composed of video / audio as an example. However, the present invention is not limited to this. It may be information, information such as an Internet homepage, or text / image / video / multimedia information for the purpose of selling products.

  In the first embodiment of the present invention, the recommended program information acquired and processed by the recommended information acquisition / processing unit 113 is information related to a program distribution service that distributes video and audio via communication. However, the present invention is not limited to this. For example, program information other than the program being viewed received by the broadcast receiving unit 101 may be used.

  As described above, by performing automatic switching determination of multiplexed display in the digital television receiving device 100, the viewer can perform broadcasting suitable for presenting recommended information simultaneously with viewing of a broadcast program such as a news program. When viewing a program, the recommended information screen is automatically displayed in multiple layers without requiring prior learning, that is, without depending on the learning result and without pressing a dedicated button.

(Embodiment 2)
With reference to FIG. 5, a description will be given of an automatic switching determination procedure for multiplexed display in the recommended screen transition control unit 112 of the digital television receiver 100 according to Embodiment 2 of the present invention. Here, FIG. 5 is a flowchart showing an automatic switching determination procedure for multiplexed display in the recommended screen transition control unit of the digital television receiver according to Embodiment 2 of the present invention.

  The configuration of the digital television receiver according to the second embodiment of the present invention is the same as that of the digital television receiver 100 according to the first embodiment of the present invention shown in FIG. 1, and in the second embodiment of the present invention. Discloses a method different from that of the first embodiment of the present invention regarding the “multiplexed display automatic switching determination procedure” in the recommended screen transition control unit 112. The automatic switching determination procedure in the second embodiment of the present invention will be described below.

  5, step S501 to step S504 are the same as step S201 to step S204 shown in FIG. 2, respectively, and step S508 to step S510 are the same as step S208 to step S210 shown in FIG. 2, respectively. Here, only the part of the determination procedure different from that of Embodiment 1 of the present invention will be described.

  If it is determined in step S503 that the genre (sub-genre) of the program being viewed is an automatic switching target (Yes in step S503), the recommended screen transition control unit 112 displays the program explanation data processing unit 111. It is determined whether or not the currently viewed program has subtitles based on the program related information related to the currently viewed program input from (S505).

  In addition, as a method for determining whether or not the program being viewed has subtitles, in addition to the method using program related information that is information related to the program being viewed, for example, the Japan Radio Industry Association In the case of broadcasting compliant with ARIB STD-B10 and ARIB STD-B24, which are standards relating to digital broadcasting of (ARIB: Association of Radio Industries and Businesses), in the definition information of each stream in PMT (Program Map Table) A method of using the presence / absence of a stream including a stream type value (for example, subtitles for 0x06) can be considered.

  If it is determined in step S505 that the program being viewed has subtitles (Yes in step S505), the recommended screen transition control unit 112 provides the recommended information to the recommended information acquisition / processing unit 113. When the program being viewed is determined not to have subtitles (No in step S505), the recommended screen transition control unit 112 acquires and processes recommended information. The unit 113 is instructed to cancel the multiplexed display of the recommended information (S507).

  In other words, the recommended screen transition control unit 112 indicates to the recommended information acquisition / processing unit 113 that the program being viewed belongs to the genre (sub-genre) that is automatically switched to the multiplexed display in step S503. If it is determined that the program is a program, and it is determined in step S505 that the program is a captioned program, an instruction is given to multiplex display the recommended information as shown in step S506, otherwise Then, as shown in step S504 and step S507, an instruction is given to cancel the multiplexed display of recommendation information.

  Note that the determination based on whether or not the program being viewed in Embodiment 2 of the present invention has captions is combined with the determination based on the length of the broadcast time of the program being viewed in Embodiment 1 of the present invention. It is easy to infer that it is possible.

  As described above, by performing automatic switching determination of multiplexed display, it is relatively easy to convert the content into text information when the program has news with captions, etc. Because it is possible to prepare recommended programs according to the content of news in a relatively short time, only when a more appropriate recommended program is prepared, the broadcast program video and the recommended selection screen are automatically displayed. It becomes possible to switch to the multiplexed display, and the convenience for the viewer is further improved.

(Embodiment 3)
With reference to FIG. 6, the automatic switching determination procedure for multiplexed display in the recommended screen transition control unit 112 of the digital television receiver according to Embodiment 3 of the present invention will be described. Here, FIG. 6 is a flowchart showing an automatic switching determination procedure for multiplexed display in the recommended screen transition control unit of the digital television receiver according to Embodiment 3 of the present invention.

  The configuration of the digital television receiver according to Embodiment 3 of the present invention is the same as that of digital television receiver 100 according to Embodiment 1 of the present invention shown in FIG. 1, and in Embodiment 3 of the present invention. Discloses a method different from the first and second embodiments of the present invention regarding the “multiplexed display automatic switching determination procedure” in the recommended screen transition control unit 112.

  Some programs are divided into a plurality of times (sections) and include a plurality of contents. For example, a news program is composed of a plurality of news items such as politics, economy, incidents, and sports. Furthermore, in the same news program, there may be a mixture of sections that are broadcast as headlines in a relatively short time and sections that are broadcast using a relatively long time as a feature article. In other words, there may be a mixture of a short section in which the multiplexed display of the recommendation selection screen is desirable and a long section in which the multiplexed display is not desirable.

  As a method of dividing the program being viewed into a plurality of times, for example, it is divided at the time of program production, or is divided by script information acquired in advance by the center device of the program distribution service, or the video / audio of the program in the digital television receiving device 100 And a method of analyzing and separating other information.

  The time delimiter information in the program delimited at the time of program production and the time delimiter information in the program delimited by the center device of the program distribution service are given from the center device to the digital television receiver 100 by a method using means such as communication. It is done.

  The automatic switching determination procedure for multiplexed display according to Embodiment 3 of the present invention uses the time separation information in the program obtained by the above-described predetermined method, and displays the broadcast program video and recommendation selection screen for each section. Whether or not to switch to the multiplexed display can be determined, and the automatic switching determination procedure for the multiplexed display will be described below.

  In FIG. 6, the determination of automatic switching of multiplexed display for each section is started (S601). The timing for starting the automatic switching determination is determined after the program being viewed in the first or second embodiment of the present invention is determined to be multiplexed or displayed at a plurality of times. This is a case where it is determined whether or not to switch to the multiplexed display of the broadcast program video and the recommendation selection screen for each divided section.

  When the determination of automatic switching of multiplexed display for each section is started, first, it is determined whether or not the broadcast time of the section being viewed is shorter than a predetermined time (S602).

  If it is determined in step S602 that the broadcast time of the section being viewed is shorter than a predetermined time (Yes in step S602), the recommendation screen transition control unit 112 determines the recommendation information acquisition / processing unit. 113 is instructed to display the recommended information in a multiplexed manner (S603), and when it is determined that the broadcast time of the section being viewed is not shorter than a predetermined time (in the case of No in step S602). In step S604, the recommendation screen transition control unit 112 instructs the recommendation information acquisition / processing unit 113 to cancel the multiplexed display of the recommendation information.

  In step S603 or step S604, after the recommendation information acquisition / processing unit 113 receives an instruction from the recommendation screen transition control unit 112 and takes a corresponding action in each step, the remaining time (section) of the program being viewed is plural. It is determined whether or not it is divided into sections (S605).

  In step S605, when the remaining time (section) of the program being viewed is divided into a plurality of sections (Yes in step S605), the process waits until the end of the remaining section of the program being viewed (S606). Thereafter, the process returns to step S602 to continue the processing. If the remaining time (section) of the program being viewed is not divided into a plurality of sections (No in step S605), the multiplexed display for each section is performed. The automatic switching determination is terminated (S607).

  As described above, by performing automatic switching determination of multiplexed display, in a program composed of a plurality of sections having different contents, a section that is expected to be deeply informed by the viewer is short Thus, it is possible to automatically switch to the multiplexed display of the broadcast program video and the recommendation selection screen, and the convenience of the viewer is further improved.

(Embodiment 4)
When a broadcast program video and a recommendation selection screen (“program information” described in claims) are multiplexed and displayed by the automatic switching determination method for multiplexed display in the first to third embodiments of the present invention, In order to select a recommended program while viewing the broadcast program image, it is desirable that the display area of the broadcast program image is relatively large. The display area of the broadcast program image being viewed is not satisfactory if the length of one side is 2/3, and if it is 5/6 or more, it is considered difficult to display the recommended information on the recommendation selection screen. One of the solutions is to determine the display area of the broadcast program video being viewed corresponding to the genre (sub-genre).

  The configuration of the digital television receiver according to Embodiment 4 of the present invention is the same as that of digital television receiver 100 according to Embodiment 1 of the present invention shown in FIG. Discloses a method of determining the size of the display area of the multiplexed display in the video signal output unit 108.

  Thus, by setting the size of the display area of the broadcast program video for each genre (sub-genre), it becomes possible to perform multiplexed display more appropriately.

  Furthermore, the size of the display area of the broadcast program video is determined according to the length of time of the broadcast program being viewed or the length of the break (section) in the program according to Embodiment 3 of the present invention. By doing so, it becomes possible to perform multiplexed display more appropriately.

  Note that the genre determination table in the fourth embodiment of the present invention in which the size of the display area of the broadcast program video is set as well as the target / non-target of the automatic switching for each genre (sub-genre) is the implementation of the present invention. As in the genre determination tables in Embodiments 1 to 3, the viewer (user) can make changes using the setting screen prepared in advance via the user operation I / F unit 110 shown in FIG. It is desirable to do so.

  In addition, the present invention can provide not only the apparatus according to Embodiments 1 to 4 of the present invention as a broadcast wave receiving apparatus including each means (each unit) but also each means included in the broadcast wave receiving apparatus as each step.
