Abstract
PURPOSE: To make a sub-channel picture static temporarily by preventing contents of a memory, where sub-channel picture signals are stored, from being rewritten in the television receiver which can project a main channel picture and a sub- channel pictur on the screen simultaneously.
CONSTITUTION: When it is desired to make a sub-channel picture static, selector switches 39 and 40 are switched to supply pulses of read clock pulse oscilator 34 to read/write selection circuit 29, and compressed sub-channel signals which are obtained from video amplifier circuit 38 are supplied to memories 35 and 36. Then, sub-channel signals read out alternately from one of memories 35 and 36 written to the other of memories 35 and 36 respectively in the same high speed as the read time, and as a result, the sub-channel picture on the screen becomes a static picture.
