Transport stream multiplexing method, transport stream multiplexing apparatus, and storage and reproduction system

摘要

When forming an MPEG-TS (transport stream) containing access units which are units of access of MPEG data, transfer timing is controlled in a transfer timing control section(102) under control of a transfer control section(101). Access units are thus sent as TS packets from an access unit transfer processing section(103). A new PTS(Presentation Time Stamp) is embedded in a PES header supplied from a PES header transfer control section(104), by a PTS embedding section(105). A TS packet sequence containing both of them is formed by a reproduction buffer(106). On the other hand, a PCR(Program Clock Reference) serving as a time reference is embedded in a TS packet supplied from a PCR transfer control section(109) and a resultant TS packet is sent to a PCR buffer(111), by a PCR embedding section(110) on the basis of a STC(System Time Clock) supplied from an STC section(108). The TS packets are multiplexed as a TS packet sequence to form an MPEG-TS, by a TS multiplexing section(112).
