Claim:
A recording apparatus for compression-coding video data and recording the compression-coded video data, comprising: an encoder compression-coding video data using interframe compression based on predictive coding for each of groups each including a plurality of pictures, a plurality of pictures including at least one independently-decodable picture; and a mark information generator generating mark information indicating an access position to the groups of the video data, wherein, when the access position is designated to one of the groups decodable without use of information on a closest past group in reproduction order, the mark information generator generates the mark information indicating a position which return from the access position to a top of the decodable group, the mark information indicating a position within a playlist layer that is a layer above a clip layer in which the compression-coded video data is arranged, the mark information being assigned to a group boundary when the group corresponding to the position of the mark information is closed, and the mark information being assigned to a presentation time stamp entry designated in the clip layer when the group corresponding to the position of the mark information is open.
