RECORDING MEDIUM, REPRODUCTION DEVICE, PROGRAM

摘要

A video stream and an entry map are recorded on a BD-ROM. The entry map indicates a plurality of entry positions (SPN_EP_start) in the video stream while correlating them with the entry time (PTS_EP_start) and a flag (is_angle_change_point). The flag (is_angle_change_point) indicates whether the picture existing at the entry position (SPN_EP_start) is an IDR picture intending refresh operation of decoding or a Non-IDR picture requiring reference of the preceding picture. ® KIPO & WIPO 2007
