Video processing system with layered video coding and methods for use therewith
View Patent ↗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 based on a motion vector data or grayscale and color data.
1. A video processing system comprising:
a video encoder that encodes a video stream into an independent video layer stream and a first dependent video layer stream;
wherein the independent video layer stream includes a plurality of grayscale data, wherein the first dependent video layer stream includes a plurality of color data, and wherein the first dependent video layer stream does not include the plurality of grayscale data.
2. The video processing system of claim 1 , wherein the independent video layer stream does not include the plurality of color data.
3. The video processing system of claim 1 , wherein decoding of the first dependent video layer stream is dependent on data from the independent video layer stream.
4. The video processing system of claim 1 wherein grayscale data includes luma data and the color data includes chroma data.
5. The video processing system of claim 1 further comprising:
a video decoder that, in a first mode of operation is coupled to receive the independent video layer stream and the first dependent video layer stream, to synchronize the independent video layer stream and the first dependent video layer stream to form a synchronized stream and to generate a reconstructed video signal based on the synchronized stream.
6. The video processing system of claim 5 wherein the video decoder, in a second mode of operation, is coupled to receive the independent video layer stream, and to generate a reconstructed video signal based on the independent video layer stream, without the first dependent video layer stream.
7. A method comprising:
encoding a video stream into an independent video layer stream and a first dependent video layer stream;
wherein the independent video layer stream includes a plurality of grayscale data, wherein the first dependent video layer stream includes a plurality of color data, and wherein the first dependent video layer stream does not include the plurality of grayscale data.
8. The method of claim 7 , wherein the independent video layer stream does not include the plurality of color data.
9. The method of claim 7 , wherein decoding of the first dependent video layer stream is dependent on data from the independent video layer stream.
10. The method of claim 7 wherein grayscale data includes luma data and the color data includes chroma data.
11. The method of claim 7 further comprising:
when in a first mode of operation:
receiving the independent video layer stream and the first dependent video layer stream;
synchronizing the independent video layer stream and the first dependent video layer stream to form a synchronized stream; and
generating a reconstructed video signal based on the synchronized stream.
12. The method of claim 11 further comprising:
when in a second mode of operation:
receiving the independent video layer stream; and
generating a reconstructed video signal based on the independent video layer stream, without the first dependent video layer stream.
