Abstract

PURPOSE:To greatly reduce the scale of a circuit, by realizing the use of a large-capacity frame memory by means of a buffer memory which stores the coded memories of a horizontal video period. CONSTITUTION:Both the horizontal and vertical periods of a color TV picture signal of a single system are divided for example into 4 parts respectively to display a picture. An A/D converter 35, etc. encodes the TV input signal into a digital signal, and buffer memories 84-87 are divided into 4 parts in terms of the time axis for the 1H period of the coded signal to be stored. The contents of these 4 memories are written in paralled into 4X4 frame memories 69-76 and then read out in parallel from these frame memories. The read-out coded signals of 4X4 systems is subjected to D/A conversions 45-47, and the analog signals are applied to a TV picture receiver.
