Description

ABSTRACT:
A video signal processing system which employs a frame memory having a single output is operated to provide both field and frame delayed signals. The frame memory is operated in a serial mode at twice the video signal sample rate. Video samples are input to the memory on alternate stages and alternate samples output from the memory are routed back into the vacant memory stages. Alternate samples output from the frame memory correspond to field and frame delayed samples.
