When the TV is turned on using the key button of the key input unit 180 and the channel to be watched is selected, the tuner 120 selects a broadcast signal received through the antenna 110 or the cable input. Only the broadcast signal of the set channel is tuned and output. Then, the signal processor 130 performs demodulation signal processing in a manner suitable for the broadcast system to be received.

That is, when the digital broadcast signal is received, the signal processor 130 restores the digital signal detected from the broadcast signal of the tuned channel in packet units, and audio data, video data, and broadcast information from the restored packet unit data. Separate the data into individual bit streams. Then, the separated audio data and the video data are decoded, respectively, and then converted into analog signals and then output through the speaker and the display means.

In the case of an analog broadcast signal, the signal processor 130 separates and restores the video signal, the video signal, and the additional information signal, respectively, and outputs the same through the speaker and the display means.

Of course, the video signal processed by the signal processor 130 is synthesized by the graphic signal output from the graphic processor 160 and the synthesizer 140 and output to the display means.
