<p>Apparatus for recording coded picture data on a recording medium receive the picture data (e.g., a video data), codes (101) the picture data using intra-frame coding and predictive coding to provide a group of pictures (GOP) which includes one I-picture and two succeeding P-pictures, generates (155) positional information (PSM) representing the positions of the two P-pictures relative to the I-picture, and records (154) the GOP including the I-picture, the two P-pictures, and the positional information (PSM) on the recording medium (160). The coded picture data maybe reproduced from the recording medium in a special reproduction mode in which data relates to the I-picture and 2 P-pictures is selectively read using the positional information (40, PSM). <IMAGE> <IMAGE> <IMAGE></p> |
