Abstract
An analog color video information signal is sampled at times determined by a first clock signal of a predetermined frequency whose phase is reversed on every consecutive horizontal line. The obtained samples are digitized and encoded for recording on a magnetic record medium, with the encoded data timed relative to a second clock signal of the predetermined frequency whose phase is continuous. The reproduced encoded data is processed under the control of two additional clock signals, each of which is of the predetermined frequency and has its phase reversed on every consecutive horizontal line. In the processing, the reproduced data is decoded, reclocked relative to a first of the two additional clock signals, has the chrominance component of the video information selectively inverted and converted back to analog form under the control of the second of the two additional clock signals.
