When the user turns on the television, the microprocessor 30 tunes and controls the first tuner 2 to tune the broadcast channel, and the broadcast signal is processed by the image processor 16 to be reproduced and output to the CRT. (ST301).

Thereafter, the microprocessor 30 searches for a signal applied from the time determiner 24 (step ST302), and time data input from the reserved time store 22 from the time determiner 24. When a predetermined result signal corresponding to the time data input from the timer 23 coincides, the current channel data from the current channel data storage 32 and the reserved channel data from the reserved channel data storage 25 Are respectively read and output to the channel data comparison unit 33.

Subsequently, when a predetermined result signal is input from the channel data storage unit 33 as the two channel data do not coincide (step ST303), the microprocessor 30 receives the mode storage unit 31. A predetermined flag is set to execute the sub-screen simultaneous output function (step ST304), and current channel data is read from the current channel data storage unit 32, and the first tuner 7 is tuned based on this data. Control is made (ST305).

In addition, the microprocessor 30 reads the reserved channel data set by the viewer from the reserved channel data storage unit 25 and tunes and controls the second tuner 2 based on the data (step ST306).

As a result, the image signal of the channel input through the second tuner 7 is controlled to be output to the sub-image input terminal SUB.

Thereafter, the image processor 16 performs an image processing operation based on a simultaneous main / sub picture signal output function (ST307).

In addition, the audio signals of the two broadcast signals that are tuned and input through the tuners 2 and 7 are controlled to be switched through the switching unit 12 so that the audio signals of the channels input through the first tuner 2 are first. The voice signal of the channel input through the second tuner 7 to the voice processor 13 is output controlled to the second voice processor 15 so that each voice processor 13 or 15 performs the corresponding voice process. (ST308 step).

On the other hand, if the current channel data and the reserved channel data match in step ST303, the normal reserved channel operation is performed (step ST309).

That is, the reserved channel data is read from the reserved channel data storage unit 25, and the first tuner 2 is tuned and controlled based on this data to perform a playback operation on the broadcast signal according to the reserved channel.

Therefore, according to the above embodiment, when a reserved time for a reserved channel is reached while watching television, the broadcast program that was watched is output to the main screen, and the reserved channel program is output to the sub-screen. It will satisfy both the general will and the will of the past.
