Patent ID: 8000585

Claim:
A non-transitory information recording medium having stored thereon a data structure for storing video information and audio information which are encoded into a system stream, together with associated management information, wherein, in the data structure: the system stream is allowed to have a first format (TS), the first format (TS) having a packet structure for storing data segmented in packets; the first format (TS) is allowed to have a constrained format used for converting the system stream from the first format (TS) to a second format (PS), the second format (PS) having a pack structure for storing data segmented in packs; with the constrained format, a predetermined number of packets are grouped and managed as a multiplexing unit, which corresponds to the pack of the second format (PS), and the system stream is managed in a data management unit (Capsule), which includes a plurality of multiplexing units; the management information contains playback sequence information (PGC) indicating a playback sequence of the system stream; the playback sequence information (PGC) is described by a combination of playback portions (Cells) corresponding to one or a plurality of continuous system streams; the management information contains connection information (connection_code) for each playback portion, the connection information (connection_code) indicating whether each playback portion is played back seamlessly from the playback portion in a previous playback sequence; and according to the constrained format, the system stream immediately before a seamless connection point is recorded to end with a complete data management unit (Capsule), when the connection information (connection_code) of the playback portion indicates a seamless playback.
