Patent ID: 8135225

Claim:
A method for encoding an RGB color space signal, comprising steps of: (a) encoding a base plane from the RGB color space signal having a color_plane_id of a first value using an H.264/Advanced Video Coding independent mode profile, wherein the color_plane_id of the first value is configured to indicate base plane encoding; and (b) encoding one or more enhanced planes having a color_plane_id of a second value by referring to the base plane, wherein the color_plane _id of the second value is configured to indicate enhanced plane encoding, and wherein the step (b) further comprises: (b-1) encoding a current macroblock by referring to a reference macroblock in an intra base plane macroblock mode, wherein the reference macroblock is a macroblock of the base plane; (b-2) encoding the current macroblock using an intra prediction mode of the base plane; and (b-3) encoding a difference between residual information generated by encoding the current macroblock and residual information generated by encoding the reference macroblock, wherein the residual information generated by encoding the reference macroblock is information generated by encoding the reference macroblock using the intra prediction mode in the base plane, and the residual information generated by encoding the current macroblock is information generated by encoding the current macroblock using a mode identical to the intra prediction mode of the base plane when the current macroblock is a macroblock included in the one or more enhanced plane.
