摘要： 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.

摘要： In a packet data processing determination apparatus (DBA1) for respectively and sequentially determining a plurality of packet data (P) composing an inputted transport stream (TS), a packet data storage section (270) stores the packet data (P) for a predetermined time period in the order in which they came. A stored packet data identifying section (270, 260) reads identification information (PIDe) from the stored packet data (P). A target packet data determining section (400) compares the read identification information (PIDe) with predetermined process information (PIDd) to determine whether the packet data (P) is to be processed.

摘要： A stream conversion apparatus 10 receives an MPEG2 transport stream as an input stream 21. To each packet contained in this stream, a time stamp assignment section 11 assigns the input time of that packet as a time stamp. A packet reduction section 12 deletes NULL packets which appear in the stream with a predetermined repetition pattern. Based on a proportions of the NULL packet in the stream, a time stamp replacement section 13 replaces the time stamp assigned to the packets which have not been deleted by the packet reduction section 12. The packets which have under gone the selective time stamp replacement are temporarily stored in the buffer 14, and outputted by the packet reading section 15 and the output section 16, such that each packet is outputted at a time indicated by the time stamp assigned to that packet.

摘要： A coding method comprises a hierarchical coding step of performing hierarchical coding for data to be coded to generate first and second code sequences, each comprising a plurality of code layers; a storage control step of storing the first and second code sequences in a storage region of a code storage means having successive addresses, respectively from opposed ends of the storage region, according to priority given to the code layers; and a priority judge step of storing a code layer in either of the first and second code sequences, which code layer has the highest priority at present, prior to the other code sequence, when an overlap occurs in the storage control step. Therefore, the code layers are stored in the storage element having limited capacity with high efficiency, whereby the utilization efficiency of the storage capacity is improved.
