Abstract:
A video processing system includes a video encoder that encodes a video stream into an independent video layer stream and a first dependent video layer stream that requires the independent video layer for decoding. A scrambling module scrambles the independent video layer stream to produce a scrambled independent video layer stream and leaves the first dependent video layer stream unscrambled.
