Patent ID: 8908772

Claim:
A video processing system comprising: a descrambling device; a video decoding device, coupled to the descrambling device, the video decoding device configurable to receive a video stream encoded into an unscrambled independent video layer stream and a scrambled first dependent video layer stream that requires the unscrambled independent video layer stream for decoding, wherein the video decoding device is further configurable to decode the video stream into a decoded video signal based on one of: a first mode of operation, and a second mode or operation; wherein, in the first mode of operation, the descrambling device, descrambles the scrambled first dependent video layer stream to produce a descrambled first dependent video layer stream, and the video decoding device produces the decoded video signal by combining the descrambled first dependent layer stream and the unscrambled independent video layer stream; and wherein, in the second mode of operation, the video decoding device produces the decoded video signal from the unscrambled independent video layer stream without the scrambled first dependent video layer stream.
