Patent ID: 8428129

Claim:
A method for encoding video data having a base layer and an enhancement layer, wherein the base layer has lower color resolution and lower spatial resolution than the enhancement layer, the method comprising the steps of: upsampling base layer information, wherein a predicted version of enhancement layer information is obtained that has higher value bit depth resolution and higher spatial resolution than the base layer, wherein, in a case of Inter coded base layer information, base layer residual data are upsampled by residual upsampling to obtain residual upsampled data and by subsequent color bit depth upsampling of the residual upsampled data and base layer motion information data are upsampled by motion upsampling, and wherein in a case of Intra coded base layer information texture of reconstructed base layer image data is upsampled by texture upsampling to obtain texture upsampled data and by subsequent color bit depth upsampling of said texture upsampled data; generating an enhancement layer residual being the difference between the enhancement layer information and said predicted version of enhancement layer information; and encoding the base layer information and the enhancement layer residual.
