JP4470609B2 - Broadcast wave selection receiving system and method - Google Patents

Description

  The present invention relates to a broadcast wave selection receiving system and method for selecting and receiving a desired channel from a plurality of channels being broadcast at the same time, and more particularly to a method for automatically selecting a desired channel. It is.

  Conventionally, for example, as shown in Patent Document 1 below, a technique is disclosed in which the importance of a back program is determined to switch to the viewing side when it is determined to be important. Specifically, a receiving device that receives a program composed of a video signal and an audio signal includes a reception processing unit that receives a plurality of programs at the same time and a determination processing unit that performs a program importance level determination process through audio analysis. Yes. The determination processing unit includes an audio decoding unit and an audio processing unit. An audio data packet is input to the audio decoding unit, and after the audio data is decoded, the audio processing unit determines the importance of the program. The criteria for this are, for example, that the voice of an announcer or spectator is raised when a game is excited during sports broadcasts. This state is determined based on results such as volume detection, audio frequency analysis, and the presence or absence of the appearance of a specific pattern. When it is determined that the program is an important program, the program is automatically switched to viewable so that the important program can be viewed without missing it.

Further, as a conventional technique, a technique disclosed in Patent Document 2 below has been proposed. This relates to a technique for outputting a speech word input as a recognition result by comparing and comparing the input speech and the recognition target vocabulary. The recognition target vocabulary can be changed and narrowed down based on user preference information. For example, even if there are millions of distributable menus for the on-des-mande movie / karaoke distribution service, using a speech recognition device that narrows the speech recognition target vocabulary according to the user's preference, the reception request The program to be played can be selected by voice.

  However, in the prior art, it has not yet been possible to select and select a program by directly recognizing and judging the content of the program intended by the viewer. For this reason, conventionally, it is impossible to select a program with high accuracy, and there is a problem that a program selected by mistake may be viewed, which is troublesome for the viewer.

  Therefore, the present invention accurately recognizes the contents of a program, determines whether or not the program is the target program of the viewer, and selects and receives the target broadcast wave accurately and a receiving system for selecting the broadcast wave. It aims to provide a method.

In order to solve the above problems, the receiving system broadcast wave selection according to the present invention includes a voice data registration means for registering the audio data of the desired person appearing in the program, receiving means for receiving a plurality of broadcast programs simultaneously (For example, tuner 1), selection means for selecting a single channel from a plurality of broadcast programs received by the reception means, and reproduction means for reproducing the broadcast program of the channel selected by the selection means (for example, A monitor 3) and a discrimination means for comparing the audio data registered in the audio data registration means with the audio data of channels other than the channel selected by the selection means and reproduced by the reproduction means; The voice data of the desired person is compared by comparing the level with the voice data of another person in a state where the discrimination result is obtained by the discrimination means. A detection means for generating a first detection signal when it is large, and a second detection signal when it is small; and when the first detection signal is obtained by the detection means, the reproduction means generates the desired person. And a control means for controlling the selection means to supply audio data of other channels to the discrimination means when the second detection signal is obtained. It is characterized by.

  The best mode for carrying out the present invention is the embodiment described below.

  An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing a broadcast wave selection receiving system in an embodiment of the present invention, FIG. 2 is a flowchart showing an operation of audio data registration in the broadcast wave selection receiving system in an embodiment of the present invention, and FIG. It is a flowchart which shows the operation | movement of the back program search of the receiving system for broadcast wave selection in the Example of invention.

  In FIG. 1, 1 is a tuner that simultaneously receives a plurality of broadcast programs including video signals and audio signals, 2 is a selection unit that selects a plurality of broadcast waves received by the tuner 1 in accordance with the respective purposes, and 3 is a selection. A monitor composed of a liquid crystal display, a cathode ray tube or the like that reproduces the broadcast signal selected by the unit 2, 4 is a control unit that controls the selection unit 3, and 5 is an operation unit. The operation unit 5 is operated by a viewer, and the output of the operation unit 5 controls the selection unit 2 by the control unit 4 to select a channel to be reproduced. Reference numeral 6 denotes a recording unit such as a video tape recorder or an HDD device, which records a program being reproduced on the monitor 3 by the operation of the operation unit 5 by the viewer. Reference numeral 7 denotes an audio data registration unit which takes in and registers the audio data of a person with the audio of the program recorded in the recording unit 6 by the operation of the operation unit 5 by the viewer. Reference numeral 8 denotes a determination unit that compares the audio data registered in the audio data registration unit 7 with the audio data of the channel received by the tuner 1 and not reproduced by the monitor 3 to determine the identity. Reference numeral 9 denotes a detection unit which determines whether the identity determined by the determination unit 8 is determined by weighting to determine whether or not a certain condition is satisfied. This condition is the level of the voice data of another person in the same program, and the first detection signal is generated when the voice data determined to be identical is greater than the level of the voice data of another person If it is smaller, the second detection signal is generated. The first detection signal is transmitted to the control unit 4 with channel data specifying a channel having the same identity. The control unit 4 controls the character information generation unit 10 based on the first detection signal, and displays the number of display channels indicating that a person registered in the channel appears on the monitor 3. On the other hand, when the second detection signal is obtained, the control unit 4 controls the selection unit 2 to supply audio data of another channel to the determination unit 8, and the registered audio as described above. The identity with the data is determined.

  Next, the operation of registering audio data according to the configuration of the above-described embodiment of the present invention will be described with reference to the flowchart of FIG. This registration starts from recording a program in which a desired person appears in the recording unit 6. As shown in step S <b> 1 of FIG. 2, the viewer performs a registration operation on the recording unit 6 through the operation unit 5 in a scene where the program is played on the monitor 3 and the intended person is speaking. As a result of this registration operation, the audio data is once taken into the audio data registration unit 7 in a period of about several tens of seconds as shown in the next step S2. This capture is only possible as a human voice by frequency analysis as shown in step S3. Once captured, the audio data is replayed and confirmed by the viewer. First, the presence / absence of voice data of a person is confirmed as shown in step S4. If there is voice data of a person, it is determined whether or not the voice data of the target person is present in the next step S5. If the result of this determination is that there is audio data of the desired person, it is confirmed whether or not it is the audio data of the intended person as shown in step S6. If there is no problem as a result of this confirmation, the viewer operates the operation unit 5 to register the target audio data as shown in the next step 7. The control of this registration is to store the voice data in the memory of the voice data registration unit 7 and register it as the reference voice data at the time of comparison.

  In this way, the voice data is registered. However, if it is determined in step S4 that there is no voice, the process is ended as it is. If the target person's voice data cannot be confirmed in step S6, the presence / absence of voice data of another person is determined in step S7. And when it is judged that there exists audio | voice data, the content is confirmed again in step S5. In the program, not only the desired person but also the voices of other persons are often mixed. In this case, the voice data of the desired person is extracted and registered. When a plurality of voices overlap, it is necessary to take a means for extracting only voice data of a desired person by frequency analysis.

  After registering audio data of a desired person, a so-called back program in which the person appears is searched and the channel is selected. This operation will be described with reference to the flowchart of FIG. As shown in step S9, the viewer operates the operation unit 5 to read out the audio data registered from the audio data registration unit 7 by the control unit 4 and supplies the audio data to the determination unit 8. Is selected and supplied to the discriminator 8. In the determination unit 8, as shown in step S10, the back program audio is acquired as audio data for a certain period of several tens of seconds. The acquired back program audio data is analyzed for the presence or absence of human audio data in step S11, and in the next step S12, the presence or absence of human audio data is detected. In step S12, when it is detected that there is voice data of a person, in the next step S13, identity is determined by comparison with the voice data registered in advance by the determination unit 8. If coincidence is obtained by this discrimination, it is detected whether or not the audio data satisfies the condition in the detection unit 9 as shown in step 14. This condition is the level of the sound level compared to the sound data of other persons in the same program. A first detection signal is generated when the audio data determined to be identical is greater than the level of the audio data of another person, and the first detection signal identifies a channel with the same identity. Channel data is attached and transmitted to the control unit 4. Based on the first detection signal, the control unit 4 controls the character information generation unit 10 as shown in step S15, and an indication that the person registered in the channel appears on the monitor 3 is the number of channels. Made with the display. The viewer looks at the character information on the monitor 3 and determines whether or not to select the channel as shown in step S16. When the channel is selected, a back program in which a desired desired person appears is reproduced on the monitor 3 as shown in step S17.

  In step S12, if there is no human voice data as a result of the voice analysis by the discriminating unit 8, the process returns to step S10 and the voice is captured again for a certain period. In step 13, when the determination unit 8 cannot obtain a match, the detection unit 9 sends a second detection signal to the control unit 4. Then, as shown in step S18, the control unit 4 controls the selection unit 2 to select another back program channel, and returns to step S10. In this manner, the audio data of the back program is supplied to the determination unit 8 and the identity with the registered audio data is determined as described above. In step S14, even if a match is obtained by the determination unit 8, if the condition is not satisfied and the second detection signal is sent to the control unit 4, the control unit 4 controls the selection unit 2 as shown in step S18. Then, another back program channel is selected and the operation returns to step S10. Here, since a plurality of sounds may be overlapped in the back program, it is necessary to extract each person's sound by frequency analysis.

  According to the above-described embodiment, desired person audio data for channel selection is registered in advance in the audio data registration unit 7, and the desired desired person audio data and received broadcast wave audio are registered. In addition to determining the identity of the data by the determination unit 8, the first detection signal is generated when the detection unit 9 compares the voice data of another person with the level of the voice data of the other person. At the same time, the controller 4 is made to send the first detection signal with the channel data specifying the identical channel. Then, the control unit 4 controls the character information generation unit 10 based on the first detection signal to display that the person registered in the channel appears on the monitor 3 as shown in step S15. Can do.

  Therefore, the viewer looks at the character information on the monitor 3 and determines whether or not to select the channel as shown in step S16. When the channel is selected, a back program in which a desired desired person appears on the monitor 3 can be reproduced as shown in step S17. The reproduced programs are only those programs in which the desired desired person appears as an important role and deserves viewing.

  In the above-described embodiment of the present invention, not only audio data is registered for a desired desired person, but also the person's name is registered together with the audio data, and the received EPG (electronic program guide) is received. ) May be used to accurately search for a target program.

  Further, in the above-described embodiment of the present invention, the desired desired person is registered only for the voice data of the person, but at the same time, the other voice data is registered together and these voice data are compared. It may be used as a standard. The other audio data includes title calls, songs, music, etc. that occur inseparably from the intended person. In this way, it is possible to more accurately identify a program in which a person appears.

  In the present invention described above, the fact that a desired person appears in the back program is displayed together with the channel display, but the program of this channel is automatically displayed on the monitor 3 on the small screen. It is possible to take various forms, such as reproduction with

  In the above-described embodiment of the present invention, for example, the audio data registration unit 7, the determination unit 8, the detection unit 9, and the like are separated, but these may be integrated by an integrated circuit.
