ABSTRACT:
In a digital signal playback device for playing back data from a recording medium on which intraframe, intrafield, interframe or interfield encoded digital video signals and digital audio signals input in the form of packets have been recorded transparently, and special playback data for special playback generated from said intraframe or intrafield encoded digital video signals has been recorded at predetermined positions, the special playback data is separated from a playback signal during special playback, and stored in a data storage circuit stores the separated special playback data. A still image slice data generator generates slice data with the motion vectors being 0 and prediction errors being 0 for all macroblocks in the slice. A data controller controls the still image slice generator such that the slice data from the still image slice generator is output for a predetermined number of frames after the special playback data of one frame or one field separated from the data storage means has been output. With the above arrangement, memory capacity is reduced, circuit size is reduced, and special playback can be realized without causing the ATV decoder to recognize the special playback mode.
