ABSTRACT:
A recording medium stores video information representing frames including intra-coded frames which are spaced by intervals. A first device is operative for sequentially accessing different places on the recording medium and sequentially reproducing different segments of the video information therefrom. During a search, a second device is operative for detecting whether or not a first segment of the video information which is currently reproduced by the first device represents first one of the intra-coded frames. During the search and after the second device detects that the first segment of the video information represents the first one of the intra-coded frames, a third device is operative for jumping a place accessed by the first device to a given place on the recording medium and enabling the first device to reproduce a second segment of the video signal therefrom. The second segment represents second one of the intra-coded frames which differs from the first one of the intra-coded frames.
