Abstract

PURPOSE: To improve the picture quality by detecting the receiving strength of the second TV signal and erasing it if the strength is weak in one TV receiver where pictures of two channels are projected onto the screen.
CONSTITUTION: Signals of channel A which are selectively received by tuner 2 are applied to signal selection circuit 13 through circuits 3, 4 and 5. Signals B selected by tuner 6 have the time base compressed and are converted to signals q, r and s for every field, and video signals obtained by combining signals of both channels are obtained at terminal 23 through signal selection circuit 13. Detector circuits 24 and 25 open gate 26 for signal C to transmit the output only when the level of both signals is strong, and two pictures are projected onto one screen only at this time. As a result, the disparity caused by disturbance of video in case of a weak video signal (specially, the second signal) is eliminated.
