    摘要: Provided are a multiplexing and demultiplexing apparatus and method for delivering an MPEG-2 TS packet error signal through a CableCARD interface. In the multiplexing apparatus, a TS packet reception unit receives TS packets, and a pre-header generation unit generates pre-headers corresponding to the received TS packets. A pre-header insertion unit inserts the pre-headers in front of the received TS packets to generate cable MPEG packets (CMPs), and an output FIFO unit stores the CMPs. A FIFO control unit transfers the CMPs without collision with CMPS of different channels, and an output signal generation unit generates output signals from the CMPs of the different channels.
