Abstract: Delay-line-refreshed video display system. The display, a television receiver, is locked to a stable clock frequency source, however, the information from which the video signals are derived arrive from the delay line memory at times which are not necessarily synchronous with this frequency. Means, including logic circuits and temporary storage circuits, derive from this asynchronous data the synchronous information required by the television display.
