ABSTRACT:
A digital video signal transmitting apparatus comprises a picture element data forming circuit for obtaining picture element data by subjecting an analog video signal to a digital pulse modulation, a transmitting picture element data producing circuit for successively producing for every one field, picture element data which are located at different picture element positions in a picture for each duration of one field and amount to 1/4 the number of picture element data corresponding to one field, among the picture element data which are successively obtained from the picture element data forming circuit in each duration of one field among first, second, third, and fourth durations of one field, and a transmitting circuit for transmitting through a transmission path a digital video signal in which the transmitting picture element data from the transmitting picture element data producing circuit are time-sequentially multiplexed.
