Abstract:
A video processing system includes a video encoder that encodes a video signal into a contiguous video stream having an independent portion and a dependent portion that requires the independent portion for decoding. A scrambling module scrambles the contiguous video stream to produce a scrambled video stream by scrambling the independent video portion and leaving the dependent portion unscrambled.
