  • Multi-format transport stream decoder
    Patent number: 7280566
    Abstract: In a multi-format transport stream decoder that performs a desired process on first transport streams of different formats to generate a second transport stream, a process request information input unit (APR) is supplied with process target packet data (Pi) and process request information (ScW) indicative of process details. A stream identification information providing unit (TSRi) provides stream identification information (TSID). A packet data retaining and identifying unit (DBA) retains each pieces of first packet data (Pi), and compares the stream identification information (TSIDe) and packet data identification information (PIDe) of the first packet data (Pi) with the process request information (ScW) to determine whether the information is to be processed.
