ABSTRACT:
An electronic device comprising: a transport stream analyzer, the transport stream analyzer adapted to receive an encrypted MPEG transport stream and to output a program stream map stream, a conditional access table stream, a program stream directory stream, an encrypted video signal stream, one or more encrypted audio streams, an entitlement control message stream and an entitlement management message stream, all as MPEG packetized elementary stream data structures; and a packet multiplexer adapted to receive the output of the transport stream analyzer and to assemble the output of the transport stream analyzer into an encrypted MPEG compliant modified program stream comprised of packs of MPEG packetized elementary stream data structures and to output the encrypted MPEG compliant modified program stream.
