Abstract

PURPOSE: To secure a high-quality picture image for the TV picture receiver which displays the pictures of different 1st and 2nd TV signals on one CRT by providing the detection circuit for the field intensity and thus removing the selection channel to the different place in the case of the weak field intensity.
CONSTITUTION: The broadcast signal of channel A is applied from antenna 1 via tuner, intermediate amplifying, detection and video amplifying circuits 2∼5. At the same time, video signal P (a) is applied to signal selection circuit 13, and the signal of channel B selected through tuner 6 is applied to control circuit 20 via circuits 7∼9. At circuit 20 signal (b) is sampled to memorize each sampling, and the memorized signal is read out in the double speed to obtain video signal (c) the time axis of which is compressed to 1/2. Circuit 13 switches selectively the emerging of signal (c) with every field, and the video signals of channels A and B are delivered in the form of combination signal (d). Field intensity detection circuits 24 and 25 are provided to channels A and B each. And in case the field intensity is weak, the channel is moved to the different place by the output of circuits 24 and 25 and via selection circuits 26 and 27 to obtain a high-quality picture.
