Abstract:
1. A system comprising: a processor configured to assign a unique designator to a source device of a packetized data stream, wherein the unique designator identifies the source device and allows a decryptor to determine decryption parameters based on the identification of the source device wherein the processor is further configured to create a unique designator signal that includes the unique designator; a multiplexer configured to multiplex a portion of the packetized data stream with a second packetized data stream to create a multiplexed signal; and a transmitter configured to transmit the unique designator in conjunction with the multiplexed signal wherein the transmitter is further configured to transmit the unique designator signal in conjunction with the multiplexed signal, wherein the unique designator signal provides the unique designator at the start of a byte of the packetized data stream.
