Patent ID: 8385544

Claim:
A packet based high bandwidth copy protection method suitable for transmitting video data from a receiver device, the method comprising the operations of: providing a plurality of source data streams each comprising video data having a different data format, said streams comprising at least a first source data stream comprising a first video stream having a first video format and a second source data stream comprising a second video stream having a second video format; packetizing the first source video stream having the first video format into a first packet stream of first data packets each of the first data packets comprising an associated packet ID and attributes enabling reconstruction of the first source video stream at a receiver; packetizing the second source video stream having the second video format into a second packet stream of second data packets each of the second data packets comprising an associated packet ID and attributes enabling reconstruction of the second source video stream at a receiver; performing one of encrypting or not encrypting selected first data packets of said first packet stream of first data packets and one of encrypting or not encrypting selected second data packets of said second packet stream of second data packets; forming a conjoined encrypted data stream comprising a series of output data transmission streams, wherein each output data transmission stream comprises one of a plurality of said encrypted data packets or a plurality of said data packets that are not encrypted, each output data transmission stream comprising, data packets from both the first packet stream and the second packet stream wherein all of the data packets of each output data transmission stream are one of, all encrypted or all not encrypted; and an associated control packet indicating whether all of the data packets of the output data transmission stream are encrypted or not encrypted; and transmitting said series of output data transmission streams to a sink device as the conjoined encrypted data stream enabling the concurrent data transmission of video data from both the first and second source video streams.
