Next, the operation of the television with the audiovisual data processing function according to the present invention configured as described above will be described in detail with reference to the flowchart shown in FIG. 3 and the screen example of FIG.

First, when the microcomputer 11 receives a control signal from the key input unit 10 (ST10), whether the control signal is a setting signal of an audiovisual mode by the audiovisual mode key 10a of the key input unit 10. If it is determined that the control signal is not a control signal for setting the audiovisual mode, the normal broadcast signal is reproduced in ST12.

That is, in the normal broadcast signal reproduction mode, the microcomputer 11 displays the OSD data by the OSD generator 21 as the OSD data with respect to the control signal input to the key input unit 10, and the key input unit 10. When the control signal for channel selection is input from the channel up / down key 10b or the 10-key 10c, the channel selection data storage unit 12 reads out the channel selection data for the corresponding channel. It applies to the tuner part 13a.

Then, the first tuner 13a performs channel selection based on the channel selection data, and the audio and video signals of the channel are transmitted to the audio IF processor 14 and the first video IF processor 17a. Will be authorized. The voice IF processor 14 performs detection and intermediate frequency (IF) processing on the voice signal and applies the IF processed voice signal to the voice processor 15. Accordingly, the voice processor 15 For example, volume control is performed on the voice signal to be amplified by the voice amplifier 16 and then output to the speaker.

At the same time, the first image IF processor 17a performs the detection and the intermediate frequency (IF) processing on the image signal and applies the IF processed image signal to the image multiple processor 18. The image multiple processing unit 18 performs luminance / contrast adjustment on the image signal, for example, to be amplified by the image amplifier 19 and then output to the CRT apparatus.

If the PIP function is set in the key input unit 10 and another channel is designated during processing of the normal broadcast signal, the microcomputer 11 corresponds to the channel to process the currently tuned channel as a sub picture. The selected channel data is read from the selected channel data storage unit 12 and applied to the second tuner unit 12b so that the video signal of the channel tuned by the second tuner unit 12b is converted into the second image IF processor. Detected at 17b and IF processed, it is applied to the image multiplexer 18.
