Abstract
An MPEG transport demultiplexer (demux) has been implemented by the use of a RISC-based microcontroller as the core of the system in order to provide flexible data processing and a possibly cost-effective solution for an IRD (integrated receiver decoder) application. The hardware part filters out the packets necessary for one program and the microcontroller receives the packet, parses the headers and contents, and transfers the elementary stream data to the MPEG video/audio decoders. The implemented system shows that it still has approximately 60% of the CPU cycles, 16 Mcycles/sec, left with a video input of 15 Mbps.
