Abstract

PURPOSE:One memory circuit of two memory circuits-which store standard TV broadcasting signals during 1H-is caused to write when the other memory circuit reads, so that it is possible to receive standard TV broadcasting by using a picture receiver for high definition broadcasting of the large number of scanning lines and a wide band width.
