Abstract
A video signal frame memory is refreshed without requiring either a separate transmission line or the transmission of bursts of data. This is done by dividing the frame signals into blocks of data, which are further divided into lines and sub-blocks. During each frame, refreshing signals are sent on a sub-block basis, thereby distributing the refreshing control signals and preventing many signals from being sent in bursts.
