Patent ID: 8199781

Claim:
An apparatus for demultiplexing in a digital broadcasting receiver for processing packet data constructed by a packet header and a payload, comprising: a buffer for buffering input packet data; and a plurality of processors parallel connected to the buffer, the plurality of processors comprising: a packet header processor for checking a packet header of the buffered input packet data, determining if adaptation information is included, and generating a control signal when adaptation information is determined to be present; an adaptation information processor, which is controlled by the packet header processor, for processing the adaptation information of the buffered input payload data; a Packetized Elementary Stream (PES) header processor, which is controlled by the packet header processor, for processing a PES header of the buffered input payload data; and a data processor, which is controlled by the PES header processor, for generating an audio or video Elementary Stream (ES) from audio or video data of the buffered input payload data, and outputting the generated audio or video ES to an associated decoder.
