Abstract:
1. A video processing system comprising: a video encoding device that encodes a video stream into an independent video layer stream and a first dependent video layer stream that requires the independent video layer stream for decoding wherein the independent video layer stream includes a first plurality of motion vector data corresponding to a plurality of motion vectors, the first plurality of motion vector data representing a plurality of most significant bits of the plurality of motion vectors, wherein the first dependent video layer stream includes a second plurality of motion vector data corresponding to the plurality of motion vectors, the second plurality of motion vector data representing a plurality of least significant bits of each of the plurality of motion vectors, and wherein the second video layer stream does not include the first plurality of motion vector data; and a scrambling module, coupled to the video encoding device, that scrambles the independent video layer stream to produce a scrambled independent video layer stream and leaves the first dependent video layer stream unscrambled.
