ABSTRACT:
The present invention provides a data stream processing apparatus which records a data stream supplied via a network. An MPEG2 partial TS and channel bandwidth information are read from a recording medium, and a bandwidth of an IEEE 1394 serial data bus is secured on the basis of the read channel bandwidth information. MPEG2-TS packets read out are buffered and time stamps are generated based on PCR decoded for a period of the buffering. Subsequently, a head having stored therein a time stamp is appended to each of the MPEG2-TS packets to generate a source packet and the source packet is sent to the other electronic device by the use of the secured channel bandwidth of the IEEE 1394 serial data bus.
