Abstract

PURPOSE: To display pictures for two channels at the same time on the video screen of one TV receiver varying the area of the video screen occupied by one channel, by varying a lateralaxis time period by varying a read frequency.
CONSTITUTION: This unit is provided with circuits from tuners 8 and 12 receiving picture signals of different channels A and B at the same time to video detection curcuits 10 and 14, and also equipped with memory circuit 20 stored with all of or some of video information of the picture signal of channel B, and control circuit 18 which can control the read sequence, read frequency and read timing of picture signals from this circuit 20. Further, this unit is provided with clock pulse generating circuit 19 connected to circuit 18 and removal circuit 21 which is controlling the read sequence of picture signals by stopping the transmission of signals read excessively in one horizontal period in order to vary the occupied area of the video screen of channel B by receiving the output of circuit 21 and the signal of channel A, thereby displaying video signals of channels A and B both on the CRT through composing selector circuit 22 at the same time.
