Abstract

PURPOSE:To make the selection of a program easy, by displaying images of multichannel TV broadcast simultaneously on one TV reception screen. CONSTITUTION:The output of tuners 2a-2c connected to an antenna input circuit 1 is connected to a display memory 5 via video intermediate frequency circuit 3a- 3c and A/D conversion circuits 4a-4c. The output of a tuner 2a is digital signal via circuits 3a, 4a and written in the specific area of the display memory 5. It is also written in the memory 5 similarly for tuner 2b on and after. When all the reception channels are written in, the data in the memory 5 is read out with the output of the address generating circuit 13, and it is input to CRT8 for display of reception.
