Patent ID: 8854427

Claim:
A method for encoding video signals, the method comprising acts of: encoding a video data signal, wherein the encoded enhanced signal comprises primary and secondary video signals in which include a primary and secondary plurality of frames respectively, wherein the frames of the primary and secondary video signals are interleaved to form an interleaved video sequence before jointly compressing; using the interleaved video sequence, jointly compressing the primary video signal and the secondary video signal into a jointly compressed video signal, wherein the primary video signal is encoded and compressed in a self-contained manner and compressed without using frames of the secondary signal, and the secondary video signal is encoded and compressed using the frames of the primary plurality of frames; splitting the jointly compressed video signal into separate primary bitstream comprising data for the primary video signal and secondary bitstream comprising data for the secondary video signal; multiplexing the primary and secondary bitstreams into an encoded video signal, wherein the primary and secondary bitstreams are separate bitstreams provided with separate codes; and outputting the primary and secondary video signals with the separate codes.
