  According to the present invention, it is possible to provide a video broadcast / audio broadcast receiving apparatus that receives video of a video channel desired by a user and audio of an audio channel by performing simple settings.

The best mode for carrying out the present invention will be described.
FIG. 1 is a block diagram of a video display device which is an embodiment of the video / audio broadcast receiving device of the present invention. In the figure, reference numeral 1 denotes a video broadcast signal reception processing unit, an antenna 3 for receiving a video broadcast signal, a tuner 4 for transmitting a broadcast station signal set by the user among the received signals, and A for digitally processing the received signal. A / D converter 5 and a decoder 6 for decoding the A / D converted signal.

  In the figure, reference numeral 2 denotes an audio broadcast signal reception processing unit, an antenna 9 for receiving an audio broadcast signal, a tuner 10 for transmitting a broadcast station signal set by the user among the received signals, and A for digitally processing the received signal. A / D converter 11 and a decoder 12 that decodes the A / D converted signal.

  A D / A conversion unit 7 and a video output unit 8 for analog-modulating the video signal of the video broadcast decoded by the decoder 6 are provided.

  An operation input unit 16, a CPU 18 a, a main control unit 18 having a memory 18 b, and an output audio setting storage unit 17 for storing rules of output audio when viewing a video broadcast set by the user from the operation input unit 16 are provided.

  An output audio switching control unit that controls which one of the audio signal of the video broadcast decoded by the decoder 6 and the audio signal of the audio broadcast decoded by the decoder 12 is output according to the rule stored in the output audio setting storage unit 17 13, a D / A converter 14 that performs analog modulation, and an audio output unit 15.

  When viewing a video broadcast program, the user sets one audio broadcast channel for one video broadcast channel with respect to the audio output, and the audio broadcast channel set when the corresponding video broadcast channel is selected Applicable by setting for each channel that audio is output as audio, and by setting the audio of one audio broadcast channel program or the audio broadcast channel program for one video broadcast channel program using EPG It is possible to appropriately select and set the audio broadcast channel set at the time of viewing the program of the video broadcast channel or the setting for each program in which the audio of the program of the audio broadcast channel is output as audio.

  In addition, there is an auto setting that can be set so that the sound of the program of the audio broadcast channel whose content is similar to the program being viewed when viewing the video broadcast channel is output by using the similar program search procedure shown in FIG. .

  An example of a similar program search procedure will be described with reference to FIG. First, program keywords are extracted from the EPG (step S1). As a method for extracting a keyword of a program from an EPG, a method proposed as an automatic keyword extraction device and method (Patent Document 3) can be used.

  Next, the video broadcast program is compared with the keywords of the audio broadcast program broadcast during the broadcast of the video broadcast program, and the audio broadcast program having more overlapping keywords is stored (step S2).

  It is determined whether there is a program having the duplicate keyword stored in step S2 (step S3). If it exists, the process proceeds to step S4, and if not, the process proceeds to step S9.

  It is determined whether there are a plurality of programs having the largest number of duplicate keywords (step S4). If it exists, the process proceeds to step S5;

  It is determined whether there are a plurality of programs having the longest broadcast time overlapping with the compared video broadcast program among the audio broadcast programs having the largest number of duplicate keywords (step S5). If it exists, the process proceeds to step S6, and if not, the process proceeds to step S8.

  It is determined whether there are a plurality of programs having the earliest broadcast start time (step S6). If it exists, the process proceeds to step S7, and if not, the process proceeds to step S8.

  The program with the lowest frequency of the broadcasting station is stored as the program with the highest similarity (step S7). Any element that is uniquely determined, such as a channel number, may be used even if it is not a frequency. Alternatively, the corresponding program is stored as the program having the highest similarity (step S8). Alternatively, it is stored as no similar program (step S9). Then, the similar program search procedure ends. In this way, the similar program search method can be performed, the specified similar program can be obtained, or no similar program can be obtained.

  An example of a procedure for determining an output audio program at the time of selecting a video channel will be described with reference to FIG. First, a video channel is selected (step S11).

  Next, it is determined whether or not the setting for each program is set for the program being broadcast (step S12). If set, the process proceeds to step S18, and if not set, the process proceeds to step S13.

  It is determined whether or not each channel is set for the selected broadcast station (step S13). If set, the process proceeds to step S18, and if not set, the process proceeds to step S14.

  It is determined whether or not the auto setting is performed (step S14). If set, the process proceeds to step S16, and if not set, the process proceeds to step S15.

  The audio of the selected video channel is output (normal viewing state) (step S15). Then, the procedure for determining the output audio program ends.

  A similar program search is performed (step S16), and the process proceeds to step S17.

  It is determined whether there is a similar program (step S17). If it exists, the process proceeds to S18, and if not, the process returns to Step S15.

  The audio channel to be output or the audio of the audio channel program is output (step S18). Then, the procedure for determining the output audio program ends. In this way, it is possible to determine an output audio program when selecting a video channel.

Detailed operations when various settings are applied will be described.
In the auto setting, keywords of the video channel / audio channel program are extracted from the EPG, and the program having the highest similarity is searched based on the extracted keyword. When the auto setting is set to ON, the audio of the audio channel program with the highest similarity is automatically output as audio when viewing the video channel program. When the audio channel that has been output before the end of the program on the video channel ends, the search is performed again, and the audio output is switched to the audio of the program of the audio channel with the highest similarity at that time.

  In the individual setting for each channel, one audio channel is set for one video channel. The audio of the audio channel set when the corresponding video channel is selected is output as audio.

  In the individual program setting, one audio channel or audio channel program is set for one video channel program. The audio of the audio channel set when viewing the program of the corresponding video channel or the program of the audio channel is output as audio. After the program ends, the normal viewing state is restored.

  Note that the output video for the audio channel can be set in the same manner as the output audio for the video channel.

It is a figure which shows the outline | summary of the apparatus which has both the video broadcast receiver and audio | voice broadcast receiver to which this invention is applied. It is an example of the flowchart of a similar program search. It is an example of the flowchart for the output audio | voice determination at the time of video broadcast reception.
