Description

  The present invention relates to a digital broadcast receiving apparatus, a digital broadcast receiving method, and a program.

  In television broadcasting, broadcasting of a program (hereinafter referred to as “video content”) in which video and audio data is digitized using terrestrial broadcasting, satellite broadcasting, and a dedicated line is widespread. In recent years, broadcasting of a plurality of video contents has been performed by a large number of broadcasters (for example, broadcast stations). Note that there may be one video content broadcast by one broadcaster, but there may be a case where one broadcaster broadcasts a plurality of video contents in the same time zone on a plurality of channels. For this reason, television receivers, which are digital broadcast receivers that receive video content, so-called televisions, watch the scheduled broadcast time of video content (programs) broadcast on many broadcasters and channels and the contents of the programs. A function of generating an electronic program guide (EPG) for presentation to a television user who is a user is provided. The user can view a desired program by selecting any broadcaster or channel shown in the electronic program guide.

  However, not all video content (programs) can always be viewed on a television. In Patent Document 1, for example, a program that has become unable to be received due to deterioration in the reception status of satellite broadcast waves due to factors such as rain attenuation can be selected and viewed on the electronic program guide. There has been disclosed a technique of a broadcast receiving apparatus that informs a user of a program that cannot be viewed by removing it from the program options.

The The broadcast receiving unit 11 receives broadcast radio waves transmitted from the transmission device 20. Then, the broadcast receiving unit 11 outputs a broadcast signal obtained by converting the received broadcast radio wave to the demodulation unit 161 provided in the control unit 16.

  For example, the infrared communication unit 12 is a communication unit that performs infrared communication with a remote controller RC that is operated by a viewer who is a user of the reception device 10 to control the reception device 10. The infrared communication unit 12 receives an infrared transmission signal that is transmitted from the remote controller RC and includes information representing a user operation accepted by the remote controller RC.

You may comprise including the memory to memorize | store, what is called a video memory.

  The control unit 16 performs various processes on the broadcast signal output from the broadcast receiving unit 11, and generates an audio signal and an image signal corresponding to the program data i1 included in the broadcast signal. Then, the control unit 16 outputs the generated audio signal to the audio output unit 13 and the image signal to the display unit 14. In addition, the control unit 16 generates an image signal of the electronic program guide i3 based on the program arrangement information i2 included in the broadcast signal output from the broadcast receiving unit 11, and outputs the image signal to the display unit 14.

  The demodulator 161 demodulates the broadcast signal (for example, transport stream) output from the broadcast receiver 11. The demodulator 161 outputs the demodulated broadcast signal to the separator 162. Note that the broadcast signal output from the demodulation unit 161 is a signal in a state where the program data i1 and the program arrangement information i2 are multiplexed.

  The separation unit 162 separates the program data i1 and the program arrangement information i2 included in the broadcast signal output from the demodulation unit 161 (for example, the transport stream demodulated by the demodulation unit 161). Then, the separation unit 162 outputs the program arrangement information i2 separated from the broadcast signal to the program table generation unit 1642 included in the display processing unit 164. The separation unit 162 extracts audio data and video data from the separated program data i1. Then, the separation unit 162 outputs the audio data extracted from the program data i1 to the audio processing unit 163 and the video data to the video processing unit 1641 included in the display processing unit 164. Note that the audio data and video data extracted by the separation unit 162 are data encoded in a predetermined encoding method. When the program data i1 includes only one of audio data and video data, the separation unit 162 converts the separated data to the corresponding audio processing unit 163 or video processing unit 1641. Output to either one of

  The audio processing unit 163 decodes the audio data output from the separation unit 162 using a predetermined decoding method corresponding to an encoding method (for example, MPEG-4 audio) in which the audio data is encoded. A signal (for example, an audio signal in a stream format) is generated. The audio processing unit 163 outputs the generated (decoded) audio signal to the audio output unit 13.

For example, the display processing unit 164 generates an image signal based on the video data of the selected program included in the operation content information output from the infrared communication unit 12 and outputs the image signal to the display unit 14. In addition, the display processing unit 164 generates an image signal of the electronic program guide i3 in response to an instruction to display the electronic program guide included in the operation content information output from the infrared communication unit 12, and outputs the image signal to the display unit 14. .

  The video processing unit 1641 decodes the video data output from the separation unit 162 by a predetermined decoding method (for example, HEVC) in which the video data is encoded (for example, HEVC) (for example, , A stream format image signal). The video processing unit 1641 outputs the generated (decoded) image signal to the display unit 14. Note that the video processing unit 1641 generates an image signal obtained by decoding the video data of the program separated and selected by the separation unit 162 based on the operation content information output from the infrared communication unit 12 and outputs the image signal to the display unit 14.

  The program guide generation unit 1642 generates an image signal of the electronic program guide i3 based on the program arrangement information i2 output from the separation unit 162. The program guide generator 1642 outputs the generated image signal of the electronic program guide i3 to the display unit 14. More specifically, an image signal of the electronic program guide i3 is generated based on MH-EIT included in the program arrangement information i2 output from the separation unit 162, and is output to the display unit 14.

  Here, an outline of processing in which the program guide generation unit 1642 generates the electronic program guide i3 based on MH-EIT will be described. First, the program guide generation unit 1642 acquires program identification information and broadcast date information from the MH-EIT included in the program arrangement information i2 output from the separation unit 162. More specifically, the program guide generating unit 1642 acquires the event identification number described in the event identification (event_id) included in the MH-EIT as the program identification information. Further, the program guide generation unit 1642 uses the start time of the event described in the start time (start_time) included in the MH-EIT and the duration of the event described in the duration (duration) as broadcast date information. get. Subsequently, the program guide generation unit 1642 generates an area to which each program is assigned in the electronic program guide i3, that is, a framework of each program in the electronic program guide i3, based on the acquired broadcast date and time information. Then, the program guide generating unit 1642 arranges the acquired program identification information data in the allocated area (framework). The program guide generation unit 1642 performs the process of generating the electronic program guide i3 on the number of program arrangement information i2 output from the separation unit 162, that is, the broadcast radio waves of the respective channels received by the broadcast reception unit 11. The final electronic program guide i3 is generated repeatedly. Then, the program guide generation unit 1642 outputs the generated image signal of the final electronic program guide i3 to the display unit 14.

  By the way, the program data i1 included in the broadcast radio wave multiplexed and transmitted by the broadcast receiving unit 11 includes video data of various resolutions. The receiving device 10 may not support high-resolution programs. For example, it is conceivable that the display unit 14 included in the receiving device 10 cannot display an image corresponding to high-resolution video data. Further, for example, the video processing unit 1641 provided in the receiving device 10 may not be able to decode the high-resolution video data extracted by the separation unit 162. Further, for example, the broadcast receiving unit 11 provided in the receiving device 10 may not be able to receive broadcast waves including high-resolution video data in the first place. In such a case, the receiving apparatus 10 cannot view the program selected by the user. For this reason, the program guide generation unit 1642 displays the area (framework) assigned to the high-resolution video program that cannot be viewed by the receiving apparatus 10 in a display different from the areas (framework) assigned to other programs. The generated electronic program guide i3 is generated. That is, the program guide generation unit 1642 generates an electronic program guide i3 that can distinguish and identify programs that can be viewed by the receiving apparatus 10 and programs that cannot be viewed. Thereby, the program guide production | generation part 1642 alert | reports to a user the program which cannot be viewed.

  In addition, as a method of changing the display of the framework in the electronic program guide i3 in order to notify the user of a program that cannot be viewed, for example, the program framework that cannot be viewed is grayed out to make it inconspicuous. In other words, there is a way to gray down. In addition, for example, the program identification information data in the program framework that cannot be viewed, for example, the color of the program framework that cannot be viewed is different from the color of the program framework that can be viewed. There is also a method of not arranging (that is, not displaying information such as program name and program description). For example, there is a method of displaying a message indicating that the program cannot be viewed, such as “This program cannot be received” within the framework of the program that cannot be viewed. Such a message may be displayed when, for example, the user operates the remote controller RC and selects a framework representing a program that cannot be viewed.

  When selecting a framework (program) displayed in the electronic program guide i3, the cursor superimposed on the electronic program guide i3 is moved by operating the remote controller RC to indicate the selected program. Can be selected. In this case, a program that cannot be viewed may not be selected by skipping (skipping) the framework of the program that cannot be viewed. In this case, for example, a message indicating that the framework of a program that cannot be viewed has been skipped (for example, “program that cannot be selected” has been skipped) may be displayed superimposed on the electronic program guide i3.

  It should be noted that which of the above-described methods is used to notify the user of a program that cannot be viewed by, for example, operating the remote controller RC at the time of initial setting of the receiving device 10 or the like. You may make it the structure set to the apparatus 10. FIG.

  With such a configuration, the receiving apparatus 10 notifies the user of programs that cannot be viewed depending on the resolution of the received video content.

  Next, the generation process of the electronic program guide i3 by the program guide generation unit 1642 will be described in more detail. FIG. 8 is a flowchart showing a processing procedure of processing for generating the electronic program guide i3 in the digital broadcast receiving device (receiving device 10) of the present embodiment. Note that the generation process of the electronic program guide i3 by the program guide generation unit 1642 is, for example, that the user issues an instruction to display the electronic program guide by operating the remote controller RC, and the infrared communication unit 12 The process is started after receiving the infrared transmission signal from the RC and outputting the operation content information indicating that the instruction to display the electronic program guide has been received to the control unit 16.

  When operation content information indicating that an instruction to display an electronic program guide has been received is input to the control unit 16, the control unit 16 first demodulates the broadcast signal output from the broadcast reception unit 11 by the demodulation unit 161. Then, the program data i1 and the program arrangement information i2 included in the demodulated broadcast signal are separated by the separation unit 162, thereby extracting the program arrangement information i2 from the broadcast signal (step S101).

  Subsequently, the program guide generation unit 1642 acquires program identification information and broadcast date information from the MH-EIT included in the program arrangement information i2 output from the separation unit 162. And the program schedule production | generation part 1642 comprises the framework of the electronic program schedule i3 based on the acquired broadcast date information (step S102). At this time, the program guide generation unit 1642 arranges the acquired program identification information data, that is, information such as the program name and program description to be displayed in the corresponding framework of the electronic program guide i3.

  Subsequently, the program guide generation unit 1642 performs a resolution determination process of video data (hereinafter referred to as “video data determination process”) for each program of the framework configured in the electronic program guide i3 (step S103). In the video data determination process, first, the value of the video signal resolution in the video component descriptor is acquired from the MH-EIT included in the program arrangement information i2 corresponding to the configured framework. Then, it is determined whether the acquired video signal resolution value is a resolution value that can be viewed, that is, displayed on the display unit 14 (step S104). As shown in FIG. 6, the value of the video signal resolution increases as the value increases. Therefore, in determining whether or not the program performed in step S104 can be viewed, the current determination is performed when the value of the video signal resolution is equal to or less than the resolution value that can be displayed on the display unit 14. It is determined that the image of the video data of the frame, that is, the program of this frame can be viewed, and if the value is larger than the resolution value that can be displayed on the display unit 14, the program of this frame is selected. It is determined that viewing is not possible.

  The determination in step S104 as to whether or not the program can be viewed is stored, for example, in the storage unit 15 by the comparison unit provided in the program table generation unit 1642 and the acquired video signal resolution value. Alternatively, it may be configured by comparing with a resolution value that can be displayed on the display unit 14.

  If it is determined by the determination in step S104 that the program of the currently determined framework is a program having a resolution that can be viewed (“YES” in step S104), the program guide generation unit 1642 The video data determination process is repeated for the program of the next framework configured in Table i3.

  On the other hand, if it is determined by the determination in step S104 that the program of the framework currently being processed is not a resolution that can be viewed (“NO” in step S104), the program table generation unit 1642 The display of the frame that is being determined is changed (step S105). And the program schedule production | generation part 1642 repeats video data determination processing about the program of the next framework comprised in the electronic program guide i3.

  Note that the change in the display of the framework in step S105 may be, for example, a configuration in which the program guide update unit provided in the program guide generation unit 1642 updates the display of the framework currently being determined.

  As described above, the program guide generation unit 1642 repeats the video data determination process (step S103), and determines the resolution of the video data for all the programs constituting the framework in the electronic program guide i3. When the determination of the resolution of the video data for all the programs is completed, the program guide generation unit 1642 outputs the generated electronic program guide i3 to the display unit 14 (step S106) and presents it to the user. The generation process of Table i3 is terminated.

  By such a processing procedure, the program guide generation unit 1642, that is, the receiving apparatus 10 displays the framework of the program that can be viewed and the program that cannot be viewed based on the resolution of the received video content. Is generated and presented (notified) to the user. Thereby, the user can visually confirm whether or not the program can be viewed from the display of the electronic program guide i3.

  Here, an example of the electronic program guide i3 generated by the program guide generating unit 1642 and displayed on the display unit 14 will be described. FIG. 9 is a diagram schematically showing an example of the electronic program guide i3 generated in the digital broadcast receiving device (receiving device 10) of the present embodiment. In the following description, it is assumed that the receiving device 10 is a television having a function of allowing viewing of a 4K size resolution program. An example of the electronic program guide i3 shown in FIG. 9 shows a case where one broadcaster (broadcast station) broadcasts each program on three channels.

  As shown in FIG. 9, in the electronic program guide i3, the name of each channel is shown in the first row from the top of the electronic program guide i3 displayed on the receiving device 10, and the broadcast time of the program is shown in the electronic program guide. It is shown in the leftmost column of i3. In the electronic program guide i3, the broadcast date and time of each program is represented by a frame determined by the channel name shown in the first row from the top and the broadcast time shown in the leftmost column. If there are a large number of broadcasters such as broadcast stations, the names of broadcast stations that broadcast programs on each channel may be shown above the channels shown in the first row in FIG.

  When the user issues an instruction to display the electronic program guide to the receiving device 10, the program guide generating unit 1642 included in the receiving device 10 performs the above-described electronic program guide i3 generation processing and configures each of the configured frameworks. An electronic program guide i3 in which program identification information is arranged is generated. The example shown in FIG. 9 shows an example where the broadcast station broadcasts a 4K resolution program on each channel and an 8K resolution program on each channel. More specifically, in the example shown in FIG. 9, between “7” and “9”, a 4K size program P11 (“Good Morning Japan”) is displayed on channel A, and a 4K size program P12 (“good morning Japan”) is displayed on channel B. An example is shown in which “Morning News”) is broadcast on channel C on a 4K-sized program P13 (“Today's Weather”). The example shown in FIG. 9 shows an example in which an 8K-sized program P21 (“Sports”) is broadcast on all channels A to C during “9” to “12”. Yes. Further, in the example shown in FIG. 9, "12" when ~ "13" o'clock, the channel A in the 4K size program P31 ( "Hello Japan"), and an 8K size channel B program P32 ( "Hello Japan" ) Shows an example in the case of broadcasting a 4K size program P33 ("afternoon weather") on channel C.

  Then, the program table generator 1642 acquires the value of the video signal resolution in the video component descriptor from the MH-EIT included in the program arrangement information i2, and the program that cannot be viewed by the receiving device 10 is arranged. Change the display of the framework. In the example illustrated in FIG. 9, the receiving device 10 has a function of viewing a 4K size resolution program, that is, a television that cannot view an 8K size resolution program. Therefore, as shown in FIG. 9, the program guide generation unit 1642 has a framework of 8K size programs P21 and P32 that cannot be viewed, and 4K size programs P11, P12, and programs that can be viewed. An electronic program guide i3 is generated and displayed on the display unit 14 so that the framework of P13, program P31, and program P33 can be distinguished and identified. The example shown in FIG. 9 shows a case where an electronic program guide i3 in which an 8K size program is grayed down is generated and displayed on the display unit 14.

  As shown in the example of FIG. 9, the program guide generation unit 1642 includes a program that cannot be viewed by the user in the electronic program guide i3 by changing the display of the framework of the program that cannot be viewed. It is visually shown (notified). Thus, the user can easily recognize a program that cannot be viewed by checking the electronic program guide i3.

  In the example shown in FIG. 9, the program P31 and the program P32 that are broadcast between “12” and “13” in channel A and channel B are programs having the same content, but the resolution of the video data is the same. Because it is different, the display of the framework is different. However, when the resolutions of the video data of the program P31 and the program P32 are the same resolution (for example, 4K size), the display of the frame can be made the same. In this case, the program P31 and the program P32 may be represented by one frame.

  As described above, in addition to a method of graying down the framework of a program that cannot be viewed, a method of changing the color of the framework, as a method for indicating (notifying) a program that cannot be viewed to the user, There are various methods such as a method of not arranging (displaying) data of program identification information in the framework and a method of displaying a message indicating that the program cannot be viewed. However, these methods can be considered in the same manner as the example shown in FIG. 9 (method of graying down the program framework). Therefore, a description of an example of showing (notifying) to a user a program that cannot be viewed by a method other than the method of graying down the program framework will be omitted.

  As described above, according to the embodiment for implementing the present invention, the resolution is based on the information indicating the resolution of the video data included in the program information accompanying the program data multiplexed on the received broadcast radio wave. The user is notified of programs that cannot be viewed due to the above factors. More specifically, based on the value of the video signal resolution described in the video signal resolution in the video component descriptor included in the MH-event information table regarding the broadcast radio wave, the program and the program that can be viewed An electronic program guide that distinguishes and displays programs that cannot be recorded is generated and displayed on the display unit. Accordingly, the user can easily confirm (recognize) a program that cannot be viewed by confirming the displayed electronic program guide.

  In the embodiment for carrying out the present invention, after the program guide generation unit 1642 configures the framework of the electronic program guide i3, the video data determination processing for determining the resolution of the video data is performed for the programs of each framework. Explained. However, the video data determination process performed in the program guide generation unit 1642 is not limited to the information shown in the embodiment for carrying out the present invention. For example, when the program guide generation unit 1642 configures a framework and performs video data determination processing to place information such as a program name and a program description in the corresponding framework of the electronic program guide i3, the video signal is already A program that can be viewed and a program that cannot be viewed may be distinguished based on the resolution value.

  In the embodiment for carrying out the present invention, the case where the electronic program guide generation process is started when an instruction to display the electronic program guide is issued to the receiving apparatus 10 has been described. However, the timing for generating the electronic program guide, that is, the timing for starting the generation processing of the electronic program guide is not limited to the timing shown in the embodiment for carrying out the present invention. For example, the program guide generation unit 1642 can create (update) an electronic program guide in advance when a predetermined time interval or program information multiplexed on broadcast radio waves is updated. In this case, the image signal of the electronic program guide generated in advance is stored in the storage unit 15, and when an instruction to display the electronic program guide is issued to the receiving device 10, the program guide generation unit 1642 is stored in the storage unit 15. By reading out the stored image signal of the electronic program guide and outputting it to the display unit 14, the electronic program guide can be presented to the user more quickly.

  In addition, when an electronic program guide is created (updated) in advance, for example, a broadcasting station or channel that broadcasts a program that cannot be viewed and included in a predetermined electronic program guide, and a broadcast time of the program The information can be stored in the storage unit 15 separately from the image signal of the electronic program guide. Thus, for example, even when a user tries to directly select a program to be viewed by operating a numeric button on the remote controller RC or a channel selection button (channel button) for switching to an adjacent channel while viewing the program. , It is possible to prevent selection of programs that cannot be viewed. As a method for making it impossible to select a program that cannot be viewed, for example, there is a method of skipping (skip) a program that cannot be viewed and selecting the next program that can be viewed. In this case, for example, a message indicating that the framework of a program that cannot be viewed has been skipped may be displayed. For example, there is a method of not accepting an operation of the remote controller RC for selecting a program that cannot be viewed, that is, not responding to a user operation. For example, when a program that cannot be viewed is selected, a message indicating that the selected program cannot be viewed is displayed, such as “This program cannot be received”, and the currently selected program is displayed. There is also a method of not changing from the program that is being viewed (viewed).
