The present invention is directed to a system and method for demultiplexing video signals that have been combined using a time division multiplexing approach. The system includes synchronizers, parsers, demultiplexers, and an input buffer. Each demultiplexer within the system includes a header detect module, a slot map module, a frame sync module and a packet accept module. The method includes the steps of receiving an input stream that contains data packets for more than one program channel that have been combined in which packet identification (PID) information is used and a time division multiplexing scheme, such as transport stream multiplexing format (TSMF) is used. The PID and slot location for each packet is analyzed. Based on the PID and slot location a packet is either accepted or rejected.
