摘要

A BD-ROM has a video stream and an entry map recorded thereon. The entry map indicates a plurality of entry points (SPN_EP_start) in the video stream, in one-to-one correspondence with a plurality of entry times (PTS_EP_start) and flags (is_angle_change_point). Each flag (is_angle_change_point) indicates whether a 1picture located at a corresponding entry point is an IDR picture for causing decoder refresh or Non-IDR I picture having a reference to a preceding picture.
