Abstract:
1. In a system with a plurality of packetized data streams, a method of designating a source of at least one packetized data stream within a multiplexed signal including at least a portion of the at least one packetized data stream, the method comprising the steps of: assigning to the source device of the at least one packetized data stream, a first unique designator; assigning to the source program of the at least one packetized data stream, a program identification number: multiplexing at least the portion of the at least one packetized data stream with at least a portion of a second packetized data stream to create the multiplexed signal; and transmitting the first unique designator in conjunction with the multiplexed signal, wherein the first unique designator indicates the source device of the at least one packetized data stream.
