  ADVANTAGE OF THE INVENTION According to this invention, the broadcast receiver which can confirm the broadcast content of another channel during an accompanying broadcast can be provided at low cost.

It is a schematic block diagram of the broadcast receiver which concerns on this invention. It is a flowchart explaining the operation | movement of the broadcast receiving apparatus which concerns on this invention, the broadcast receiving method, and a broadcast receiving program.

  A broadcast receiving apparatus, a broadcast receiving method, and a broadcast receiving program according to the present invention will be described with reference to the drawings. Note that descriptions and explanations of configurations and operations not directly related to the present application are omitted. Note that a broadcast receiving apparatus that receives a television broadcast will be described as an example, but the present invention can also be applied to a broadcast receiving apparatus that receives a radio broadcast. Further, a broadcast receiving apparatus that receives a broadcast via the antenna 10 will be described as an example, but the present invention can also be applied to a broadcast reception apparatus that receives a broadcast via an Internet line or the like. In addition, outputting the broadcast content means displaying a video related to the broadcast content or reproducing an audio related to the broadcast content.

  The broadcast receiving apparatus 50 according to the present invention shown in FIG. 1 includes a tuner unit (reception unit) 30 that receives a television broadcast via an antenna 10, and decodes a television broadcast video signal received by the tuner unit 30. Video signal processing unit 14 that performs predetermined processing, converts it into a video output signal and outputs it to video output means (output means) 12 such as a liquid crystal monitor, and decodes the TV broadcast audio signal received by tuner unit 30 The audio signal processing unit 18 that performs predetermined processing such as performing and converting it into an audio output signal and outputs the audio output signal to audio output means (output means) 16 such as a speaker, and the audio of the audio output signal converted by the audio signal processing unit 18 A discriminator 32 that discriminates the broadcast content of the channel being received based on the output mode, and the tuner 30, the video signal processor 14, and the audio signal processor according to the discrimination result of the discriminator 32. A reception control unit 34 for controlling the unit (18) or the like, a has. Note that the tuner unit 30 of the present embodiment is a receiving unit that can receive a single channel broadcast.

  Next, operations of the broadcast receiving apparatus 50, the broadcast receiving method, and the broadcast receiving program according to the present invention will be described with reference to the flowchart of FIG. First, the user activates a broadcast receiving device such as a television provided with the broadcast receiving device 50. Thereby, the broadcast receiving apparatus 50 starts (step S100). Here, examples of the broadcast receiving device include a TV, a TV broadcast recording device, a TV tuner, a car stereo equipped with a TV tuner, a car navigation system, a mobile phone, a mobile mobile device, a personal computer, and the like.

  Next, the user selects a channel that broadcasts the desired main broadcast. Thereby, the tuner unit 30 receives the television broadcast of the reception channel selected by the user (step S102). Here, the channel selected by the user is described as a selected channel. Here, it is assumed that the channel of channel number (X) is selected. The video signal processing unit 14 converts the video signal of the selected channel received by the tuner unit 30 into a video output signal and outputs it to the video output unit 12. In synchronization with this, the audio signal processing unit 18 converts the audio signal of the selected channel received by the tuner unit 30 into an audio output signal and outputs it to the audio output means 16. Thereby, the broadcast content of the selected channel is broadcast from the video output means 12 and the audio output means 16.

  In general television broadcasts, accompanying broadcasts such as commercials are broadcast during the main broadcast. Many of the main broadcast audio output modes are monaural mode or audio multiplex mode, whereas many of the accompanying broadcast audio output modes are stereo modes. The discriminating unit 32 monitors the audio output mode of the audio output signal converted by the audio signal processing unit 18, and when the audio output mode of the selected channel is the monaural mode or the audio multiplexing mode, the broadcast content of the selected channel is set as the main broadcast. Judgment is made (first discrimination step S104: Yes). In this case, the reception control unit 34 does not perform any special control, so that the video output unit 12 and the audio output unit 16 broadcast the main broadcast of the selected channel as usual.

  When the audio output mode of the selected channel is the stereo mode, the determination unit 32 determines that the broadcast content of the selected channel is an accompanying broadcast (first determination step S104: No). In this case, for example, the reception control unit 34 sets the channel (X + 1), which is one number higher than the selected channel, as another channel (Y) (step S106). Then, the reception channel of the tuner unit 30 is switched from the selected channel (X) to the other channel (Y) (switching step S108). Thereby, the tuner part 30 receives the television broadcast of another channel (Y) (step S110). Then, the video signal processing unit 14 converts the video signal of the other channel into a video output signal and outputs it to the video output means 12. The audio signal processing unit 18 converts the audio signal of the other channel into an audio output signal and outputs it to the audio output means 16. Thereby, the broadcast content of the other channel (Y) is broadcast from the video output means 12 and the audio output means 16. Various known methods such as the above-mentioned [Patent Document 1] can be used as a method for determining whether the broadcast content is a main broadcast or an accompanying broadcast.

  The reception control unit 34 starts counting the timer when the reception channel is switched. Then, the broadcast content of the other channel (Y) is continuously broadcast until the predetermined time set in advance by the timer count (Step S112: No). When the count of the timer elapses a predetermined time (step S112: Yes), the reception control unit 34 switches the reception channel of the tuner unit 30 from another channel to the selected channel (step S114). At this time, the reception control unit 34 controls the video output unit 12 not to display a new video output signal from the selected channel. As a result, the last video of the other channel before switching is continuously displayed as a still image on the video output means 12. It should be noted that as a technique for preventing the display of the video output signal, it is preferable not to perform the video signal conversion process (decoding process) itself by the video signal processing unit 14. According to this configuration, the processing time of the second determination step described later can be shortened by the amount that the video signal conversion process is not performed.

  When the reception channel of the tuner unit 30 is switched to the selected channel, the audio signal processing unit 18 converts the audio signal of the selected channel into an audio output signal. At this time, the reception control unit 34 performs control so that the converted audio output signal is not output from the audio output unit 16. The discriminating unit 32 confirms the audio output mode of the audio output signal converted by the audio signal processing unit 18, and when the audio output mode is the monaural mode or the audio multiplexing mode, the discriminating unit 32 determines that the broadcast content of the selected channel is the main broadcast. (Second determination step S118: Yes). Then, the process proceeds to step S102, and the television broadcast of the selected channel is received. Then, the video signal processing unit 14 converts the video signal of the selected channel into a video output signal and outputs it to the video output means 12. The audio signal processing unit 18 converts the audio signal of the selected channel into an audio output signal and outputs it to the audio output means 16. As a result, the main broadcast of the selected channel is broadcast as usual from the video output means 12 and the audio output means 16.

  When the audio output mode of the selected channel is the stereo mode, the determination unit 32 determines that the broadcast content of the selected channel is an accompanying broadcast (second determination step S118: No). In this case, the reception control unit 34 performs an increment operation for incrementing the channel number (Y) of the other channel received previously by one (step S120). When the incremented channel number (Y) exceeds the upper limit channel number of the device, the channel number (Y) is set to the minimum value, for example, the channel number “1”. Then, the process proceeds to step S108.

  In step S108, the reception control unit 34 switches the reception channel of the tuner unit 30 to another channel of the new channel number (Y) set in step S120. Then, the broadcast contents of the new other channel are broadcast from the video output means 12 and the audio output means 16 for a predetermined time.

  These operations are repeated until it is determined in the second determination step S118 that the broadcast content of the selected channel is a main broadcast. Therefore, during the accompanying broadcast of the selected channel, the selected channel and the other channel are alternately switched, and the broadcast content of the other channel is broadcast while receiving the other channel. When a predetermined time elapses, the reception control unit 34 switches the reception channel from another channel to the selected channel. The discriminator 32 discriminates the broadcast content of the selected channel in the same manner as described above. During this time, the audio output from the audio output unit 16 is stopped and the last video of the other channel immediately before is displayed on the video output unit 12 as a still image. When the determination unit 32 determines that the broadcast content of the selected channel is an accompanying broadcast, the broadcast content of the new other channel is broadcast for a predetermined time. Therefore, every time the selected channel and another channel are switched, the other channel to be received is changed in order. The switching step S108 to the second determination step S118 mainly constitute the reception control step.

  Note that the channels may be alternately switched between the selected channel and only one other channel without changing the other channels in order. In addition, when the video signal 14 and the audio signal processing unit 18 are performing the above operation and the other channel is received, the video signal 14 and the audio signal processing unit 18 decode both the video signal and the audio signal, and the selected channel is received. In such a case, it is preferable to decode only the audio signal. In this way, the time required for the process of switching channels can be shortened.

  Note that the method for selecting the other channel is an example, and the user may specify another channel to be switched during the accompanying broadcast, for example. According to this configuration, the user can view and confirm the broadcast content of the back program that is anxious during the accompanying broadcast of the selected channel.

  As described above, according to the broadcast receiving device 50, the broadcast receiving method, and the broadcast receiving program according to the present invention, whether the broadcast content of the selected channel is the main broadcast or the accompanying broadcast based on the audio output mode of the selected channel. Is determined. During the accompanying broadcast, the broadcast contents of other channels are broadcast in order. Thereby, the user can confirm the broadcast content of the other channel during the accompanying broadcast of the selected channel. Also, the selected channel and other channels are alternately switched to confirm the broadcast content of the selected channel. Therefore, only one tuner unit 30 is required, and a broadcast receiving device having the above functions can be provided at a low cost. Further, while the broadcast content of the selected channel is being confirmed, the last video of the other channel that was aired immediately before is displayed as a still image without outputting the broadcast content of the selected channel. For this reason, the user's uncomfortable feeling during the broadcast content confirmation can be reduced.

  The broadcast receiving apparatus 50 performs the above-described operation with a single tuner unit 30. However, for example, a plurality of recording tuners may be mounted on the broadcast receiving apparatus main body. In addition, the operation, configuration, and other channel selection method of each part of the broadcast receiving device 50 described above are merely examples, and the present invention is not particularly limited thereto. The present invention can be modified without departing from the scope of the present invention. Can be implemented. Further, the present invention includes a program for causing a computer to realize the above operation. These programs may be read from a recording medium and taken into a computer, or may be taken into a computer by transmission via a communication network or the like.
