Abstract
A plurality of original video signals of channels are processed with a frame unit at intervals of a predetermined cycle in time sequence through the use of time-division multiplexing operation so as to produce a single time-division multiplexed video signal, two interlaced fields constituting one frame of the multiplexed video signal are composed of two fields of the original video signal spaced in time sequence apart from each other at intervals of a predetermined number of fields in the original video signal. In reproduction, in response to the motion of the picture, the field repetition reproducing operation and the frame repetition reproducing operation are selectively conducted so as to improve the vertical picture resolution even when the original video signal represents a picture containing a motion.
