Abstract
Abstract M/N-fold high-speed reproduction is achieved by displaying continued N frames at intervals of M frames. The order of the reproduced frames becomes 0, 1, 2, . . . , N-1, M, M+1, M+2, . . . , M+N-1, 2M, 2M+1, 2M+2, . . . , 2M+N-1, 3M, 3M+1, 3M+2, 3M+N-1, . . . . Thereby, good continuity of picture images between frames, when high-speed reproduction is performed in a video signal reproducing apparatus, can be provided.
