Abstract
PURPOSE: To make it possible to switch arbitrarily a main TV picture and a sub- TV picture by combining and operating keys in a channel selection operation part.
CONSTITUTION: When one of channel selection switches 1 to 9 in channel selection operation part 11 is turned on, code-converted channel selection information is supplied to memories 12 and 13 simultaneously. Then, channel selection information is stored only in main channel storing memory 12, and information stored previously is held in sub-channel storing memory 13. Stored information in memory 12 is supplied to decoder 7 through main channel/sub-channel switching circuit 22, and a specific channel is received in main channel receiving tuner 19. Then, when channel exchange switch 10 of operation part 11 is turned on and off twice, stored channel selection information in memory 12 is supplied to decoder 18 through main channel/sub-channel switching circuit 23, and stored information in memory 13 is supplied to decoder 17 through circuit 22. As a result, receiving channels of tuners 19 and 20 are exchanged mutually
