<p>PROBLEM TO BE SOLVED: To deal with plural kinds of various type data by using a sub-video pack consisting of a pack header and a data packet and adding a packet header and its following sub-stream ID area and packet data area to the data pack of the sub-video pack. SOLUTION: A sub-video pack 90 includes a pack header 120 of 14 bytes, a packet header 121 of 14 bytes, a sub-stream ID 141 of 1 byte and a data area 142 which can store the sub-video data of 2019 bytes or less as a sub-video packet. Then if the header 121 includes no PTS, the header 121 has a constitution of 9 bytes and the area 142 is extended to 2024 bytes. The PTS is described to only the sub-video packet that includes the head data on every sub-video unit. Thus, it's possible to deal with plural kinds of various type data.</p> |
