METHOD AND SYSTEM FOR MULTIPLE RESOLUTION VIDEO DELIVERY

1 . A method for video coding, the method comprising:

performing using one or more processors and/or circuits in a video processing system:

cropping received video content to form multiple resolution video layers comprising a base video layer and one or more enhancement video layers in different resolutions;

encoding said base video layer and said one or more enhancement video layers; and

generating composite video comprising said coded base video layer and said coded one or more enhancement video layers.

2 . The method according to claim 1 , comprising encoding said one or more enhancement video layer based on coding information associated with said base video layer.

3 . The method according to claim 2 , wherein said coding information associated with said base video layer comprises block motion vectors, block coding modes, quantization levels, and/or quantized residual data.

4 . The method according to claim 1 , wherein one or more video reception units decode said coded base video layer and decode said coded one or more enhancement video layer based on one or more of a corresponding device type utilized for video rendering, user requirement, and/or quality of said decoded base video layer.

5 . The method according to claim 4 , wherein said one or more video reception units scale said decoded base video layer to reduce a difference in resolution between said decoded base video layer and said decoded one or more enhancement video layer.

6 . The method according to claim 4 , wherein:

said one or more video reception units scale said decoded base video layer to a resolution; and

said resolution is determined based on said decoded one or more enhancement video layer.

7 . The method according to claim 4 , wherein said one or more video reception units detect a transition point for decoding said coded one or more enhancement video layer.

8 . The method according to claim 7 , wherein said one or more video reception units gradually change resolution of said decoded base video layer before and/or after said detected transition point to reduce said difference in resolution between said decoded base video layer and said decoded one or more enhancement video layer.

9 . The method according to claim 1 , wherein said received video content comprises a logo outside a cropping window utilized for said cropping.

10 . The method according to claim 9 , comprising:

determining a position within said cropping window for said logo;

extracting received video content at said determined position from corresponding video layer;

removing said received video content at said determined position from said corresponding video layer; and

inserting said logo into said corresponding video layer at said determined position.

11 . A system for video coding, the system comprising:

one or more processors and/or circuits for use a video processing system, wherein said one or more processors and/or circuits are operable to:

crop received video content to form multiple resolution video layers comprising a base video layer and one or more enhancement video layers in different resolutions;

encode said base video layer and said one or more enhancement video layers; and

generate composite video comprising said coded base video layer and said coded one or more enhancement video layers.

12 . The system according to claim 11 , wherein said one or more processors and/or circuits are operable to encode said one or more enhancement video layer based on coding information associated with said base video layer.

13 . The system according to claim 12 , wherein said coding information associated with said base video layer comprises block motion vectors, block coding modes, quantization levels, and/or quantized residual data.

14 . The system according to claim 11 , wherein one or more video reception units decode said coded base video layer and decode said coded one or more enhancement video layer based on one or more of a corresponding device type utilized for video rendering, user requirement, and/or quality of said decoded base video layer.

15 . The system according to claim 14 , wherein said one or more video reception units scale said decoded base video layer to reduce a difference in resolution between said decoded base video layer and said decoded one or more enhancement video layer.

16 . The system according to claim 14 , wherein:

said one or more video reception units scale said decoded base video layer to a resolution; and

said resolution is determined based on said decoded one or more enhancement video layer.

17 . The system according to claim 14 , wherein said one or more video reception units detect a transition point for decoding said coded one or more enhancement video layer.

18 . The system according to claim 17 , wherein said one or more video reception units gradually change resolution of said decoded base video layer before and/or after said detected transition point to reduce said difference in resolution between said decoded base video layer and said decoded one or more enhancement video layer.

19 . The system according to claim 11 , wherein said received video content comprises a logo outside a cropping window utilized for said cropping.

20 . The system according to claim 19 , wherein said one or more processors and/or circuits are operable to:

determine a position within said cropping window for said logo;

extract received video content at said determined position from corresponding video layer;

remove said received video content at said determined position from said corresponding video layer; and

insert said logo into said corresponding video layer at said determined position.
