Abstract
A demultiplexing and decoding apparatus for coded audio and video data realized with a simple circuit construction and reduced processing load, which processes a packet with higher priority over other packets, prior to the other packets. A plurality of TS packet buffers and , for storing input TS packets until they are interpreted, are set in a RAM , and processing priority orders are respectively set in the buffers. A PID filter demultiplexes a TS packet, with a PID designated in PID table , from a supplied transport stream. A TS packet with higher priority is stored into the TS packet buffer , while a TS packet with lower priority is stored into the TS packet buffer . Regardless of the input order, the TS packet stored in the TS packet buffer is processed by the CPU prior to the TS packet stored in the TS packet buffer
