ABSTRACT:
Intraframe coding and interframe coding are selectively employed for generating a compressed digital video frame in order to record a motion video signal on a small capacity recording medium such as a CD ROM. Motion compensation is also employed for effective compression, and motion compensation in only one direction is applied to an area of the frame in which interframe coding is applied that corresponds to an area of a previous frame in which the intraframe coding was applied.
