Abstract

PURPOSE:To realize states of one screen, two screens, and four screens including the channel feeding operation, by providing one set of the channel switch and three switches. CONSTITUTION:When channel selection keys for 1-12ch of channel selection switch 11 are closed, channel selecting circuit 1 selects the same positions as channel selection keys and channel selecting circuits 2-4 select large positions respectively. Meanwhile, when A of switch 11 is depressed, change-over switch 13 is switched, and outputs of receiving circuits 5-8 are input to memory 14, and four pictures of channels selected by circuits 1-4 are obtained on the screen of cathode-ray tube 15. Next, when switch A is depressed again, pictures of channels obtained by adding 4 to all circuits 1-4 are displayed. Next, when switch B is depressed, outputs of circuits 1 and 2 are applied to cathode-ray tube 15 through circuit 20 and memory 16 directly, and two pictures are obtained. Next, when switch B is depressed again, the channel of the picture of circuit 6 is increased by +1. Next, when switch D is depressed, only one picture is displayed on cathode-ray tube 15.
