Abstract
A digital video tape recorder. A clock is extracted from the horizontal sync signal within the luminance signal, and used in processing the luminance portion of the video signal. A clock is also extracted from a color burst within the chrominance signal and is used for processing the chrominance portion. The chrominance portion of the video signal to be recorded is converted to a low frequency band before recording. During playback, the reverse of this operation is performed, thereby producing a signal with the original color frequency.
