A system processes data units in a network. The system receives a data unit that includes a group of headers and suppresses one or more of the headers to form a reduced data unit. The system suppresses one or more other headers of the reduced data unit to form a further reduced data unit and transmits the further reduced data unit to one or more destination devices using the program identifier (PID) field in the MPEG header as an index to suppressed headers. |
