Description

  The present invention relates to a television receiver to which a video display device and at least an audio output device are connected.

  Conventionally, when viewing an audio multiplex broadcast including main audio and sub audio using a television receiver, the user has switched the desired audio and viewed the program. For example, in the case of a program that broadcasts the main audio in Japanese and the sub audio in English (foreign language), it is possible to switch between outputting only the Japanese main audio or outputting only the English sub audio. It is. Therefore, each time the user views, the user can select which sound to view.

Moreover, it was also possible to output the main voice and the sub voice at the same time (for example, see Patent Document 1). In this case, the main sound and the sub sound are mixedly output from the same speaker from the speaker or the like, for example, the main sound and the sub sound are distributed and output to the right and left speakers. Met.

[Constitution]
FIG. 1 is a diagram for explaining a configuration of a digital television 1 as an example to which a television receiver of the present invention is applied. As shown in FIG. 1, the digital television 1 includes a tuner unit 10, a decoder unit 20, a control unit 30, an EPG processing unit 40, a storage unit 50, a video processing signal processing unit 60, and a display device 62. An audio signal processing unit 70, a speaker 72, headphones 74, and an input unit 80, and an antenna ANT is connected thereto.

  The tuner unit 10 selects (extracts) a reception signal having a frequency corresponding to a channel set in each tuner from the reception signal received from the antenna ANT, and transports a signal (TS) in which each signal is multiplexed (TS). : Transport Stream) signal is extracted. Specifically, the received signal is demodulated by an OFDM (Orthogonal Frequency Division Multiplexing) method, and error correction is performed using Viterbi decoding or the like to extract a TS signal. Then, the extracted TS signal is output to the decoder unit 20.

  The decoder unit 20 separates the TS signal input from the tuner unit 10 into an ES (Elementary Stream) such as video or audio and outputs it. Here, the separated video ES is output to the video signal processing unit 60, and the audio ES is output to the audio signal processing unit 70. The decoder unit 20 also extracts a data broadcast stream included in the TS signal and outputs the data broadcast stream to the control unit 30.

  The control unit 30 is a processing device that controls each operation unit of the digital television 1. Each process is executed by reading and executing various programs stored in the digital television 1. Further, data related to each program is extracted from the data broadcast stream input from the decoder unit 20 and stored in the storage unit 50 as program data 502.

  The EPG processing unit 40 is a processing unit that executes processing for generating an electronic program guide (EPG) based on the program data 502 stored in the storage unit 50. An electronic program guide is generated from each received program data, and is output to the display device 62 via the video signal processing unit 60.

  The storage unit 50 is a functional unit that stores various setting data and the like, and includes, for example, a DRAM, a flash memory, a hard disk, and the like. Here, the storage unit 50 stores program data 502, common setting data 504, and individual setting data 506.

  The program data 502 is information (program information) related to a program received by the digital television 1. For example, as shown in FIG. 2, program information (for example, “1ch 19: 00 to 20:00 news”), the language of the main audio (for example, “Japanese”) as the audio information of the program, and sub audio Language (for example, “foreign language”) and a category (for example, “news”) are stored in association with each other.

  The common setting data 504 is information on setting of an output destination when outputting sound. For example, as shown in FIG. 3, a category (for example, “sports”), an audio type (for example, “main audio”), and an audio output destination (for example, “speaker (L + R)”) are associated with each other. It is remembered. Here, as the audio output destination, “speaker (L + R)” that outputs audio from both the left and right speakers, “speaker (L)” that outputs audio from only the left speaker, and the right speaker “Speaker (R)” that outputs sound only from the headphone, “headphone” that outputs sound from the headphones, “silence” that does not output sound, and the like can be selected.

  Moreover, the category of the program is set for each category. When the program information includes a category, an output destination corresponding to the category is read out. If no category is set in the program information, the category “none” is read out.

  As the voice type, in addition to “main voice”, “sub voice (foreign language)” when the sub voice is a foreign language, and “sub voice (Japanese)” when the sub voice is Japanese. ", The output destination of the voice can be stored.

  The individual setting data 506 is information that stores the setting of the audio output destination for each program. For example, as shown in FIG. 4, audio output destinations are stored in association with program information (for example, “1ch 19: 00 to 20:00 news”). The audio output destination stores an audio output destination of the main audio (for example, “speaker (L + R)”) and an audio output destination of the sub audio (for example, “speaker (L + R)”). By using the individual setting data 506, the user can set an audio output destination for each program.

  The video signal processing unit 60 is a processing unit that decodes and outputs a video signal from the video ES input from the decoder unit 20. The output video signal is output to the connected display device 62. Here, an example of the display device 62 includes a liquid crystal display device, a CRT, or the like.

  The audio signal processing unit 70 is a processing unit that decodes and outputs an audio signal from the audio ES input from the decoder unit 20. The output audio signal is output to the connected audio output device. In the present embodiment, the signal is output to the speaker 72 and the headphone 74.

  The input unit 80 is a functional unit for controlling the digital television 1 by outputting a signal input from the outside to the control unit 30. As an example of the input unit 80, for example, any method such as an operation button provided in the main body, a remote control using infrared rays, or a touch panel may be used.

[Flow of operation processing]
Next, the operation of the digital television 1 will be described with reference to FIG. The operation shown in FIG. 5 shows an operation when a program is selected on the digital television 1 and the program is specifically viewed.

  First, the control unit 30 determines whether or not there is a secondary sound in the currently selected program (step S10). Specifically, for example, the program information of the program may be referred to, or may be determined from the extracted voice. Here, when it is determined that the program has sub-audio (step S10; Yes), it is determined whether audio information can be acquired from the program data 502 corresponding to the selected program (step S12). .

  Here, when the voice information can be acquired (step S12; Yes), the control unit 30 determines the language of the sub voice from the acquired voice information. On the other hand, when the audio information of the selected program cannot be acquired (step S12; No), the “category” information of the program is read from the program data 502 (step S16). Here, the digital television 1 stores in advance language information corresponding to each category. For example, if the category is “News”, the main voice is “Japanese” and the sub voice is “English”. If the category is “Sports”, both the main voice and the sub voice are “Japanese”. Just remember. Such category information may be set by the user. In this case, language information corresponding to the category may be stored in the storage unit 50, and the corresponding language type may be read according to the program information.

  Subsequently, the control unit 30 reads from the storage unit 50 whether or not the individual setting data 506 corresponding to the currently selected program is stored (step S20). If the individual setting data 506 corresponding to the currently selected program is stored in the storage unit 50 (step S20; Yes), the individual setting data 506 is read (step S22). On the other hand, if the individual setting data 506 corresponding to the program is not stored in the storage unit 50, the common setting data 504 is read from the storage unit 50.

  For example, when the category of the program is read, the common setting data may be determined based on the audio type corresponding to the category. If the category is not read out, the output destination may be determined from the voice type of the category “none”.

  Then, the control unit 30 outputs the main sound and the sub sound according to the read main sound / sub sound output setting (step S26). Specifically, it is determined whether the sound is output from the speaker 72, the headphone 74, or both from the left and right at the same time, or is output from only one of the left and right, and the sound signal processing unit 70 is used. Output.

  As described above, according to the above-described operation flow, in the audio multiplex broadcasting, the main audio and the sub audio can be appropriately output by a method desired by the user.

  The above-described operation is an operation performed when viewing a program. Here, the operation at the time of viewing the program may be performed, for example, when the user selects a desired program and views a new program, or viewing reservation is made in advance, and the program is displayed at the reserved time. The same operation is also included when receiving / displaying.

[Example of operation]
Subsequently, the operation of the digital television 1 will be described with reference to the drawings. First, FIG. 6 shows a display screen W100 that is displayed when the user sets the audio output, that is, when the common setting data 504 is set. The user sets the audio output destinations of the main audio and sub audio. Specifically, the audio output destination of the main audio is selected from the selection menu P102, the audio output destination when the sub audio is in a foreign language is selected from the selection menu P104, and the audio output destination when the sub audio is Japanese is selected. Each is selected at P106. Here, the selected (set) content is stored in the storage unit 50 as common setting data 504.

  Next, FIG. 7 is a diagram illustrating an example when the electronic program guide W110 generated by the EPG processing unit 40 is displayed on the display device 62. Here, each program in each time zone is displayed for each channel. Information about the program surrounded by the thick frame P112 is displayed in the area P110.

  Here, an icon is displayed in the program information displayed in the area P110. For example, the icon M100 indicates that the category of the program is “news”. An icon M102 indicates that the program is broadcast in bilingual broadcasting. Thereby, the user can visually recognize the category of the program and the state of the audio multiplex broadcasting. Further, when making a viewing reservation from the screen, the user can set the output destination of the main sound and the sub sound. Here, by setting the audio output destination, when viewing the program, audio is output from the set audio output destination.

[Modification]
In the above-described embodiment, the digital television has been described as an example of the television receiver. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to, for example, a mobile phone or a car navigation system.

  In the embodiment described above, for example, the EPG processing unit 40 may display the type of language to be output on the mark. For example, as shown in FIG. 8, the mark M104 indicates that the main audio of the received program is “Japanese” and the sub audio is “foreign language”. Based on the mark M104, the user can appropriately set the output destination of the main audio / sub audio for each program.

  In the above-described embodiment, the sub audio language is determined by referring to the program data 502, but the program information may not be used. Specifically, it is determined in what language the output voice is output as the sub-voice using the voice recognition means. Then, based on the determined language, the audio output destination may be determined from the common setting data 504 and output. In this case, the recognized language type and the output destination of the sub audio may be displayed.

  For example, FIG. 9 is a diagram illustrating an example of a display screen when the sub audio of the currently received program is recognized as “English”. On the display screen, “sub audio is broadcast in“ English ”in order to notify the language of the recognized sub audio in window D100. ”Is displayed and“ Sub audio is output from “Headphone” to notify the output destination of the sub audio. Is displayed.

  In this case, even when there is no program data 502 corresponding to the received program, it is possible to appropriately output the main audio / sub audio. Therefore, the present invention can be applied to conventional television broadcasting without program information.
