Abstract:
An apparatus for reproducing picture data representing a plurality of video frames or pictures, said apparatus comprising:readout means for reading out picture data encoded from picture signals by a predictive encoding system and recorded on a recording medium;storage means for storing the picture data read out by said readout means;detection means for detecting a picture header corresponding to one of said video frames or pictures from the picture data stored in said storage means; anddelaying means for delaying an output of the picture data stored in said storage means in response to detection results obtained by said detection means, said delaying means outputting ""0""s for a predetermined time period if the picture header is detected by said detection means during varying speed reproduction and inserting outputted ""0""s only prior to a detected picture header of a video frame or picture;wherein the video frames or pictures are a sequence of intra-coded (I), inter-frame predictively coded (P) and bi-directionally predictive coded (B) frames or pictures and wherein the delaying means inserts ""0""s only prior to detected picture headers of I and B video frames or pictures.
