ADAPTIVE SYNTAX GROUPING AND COMPRESSION IN VIDEO DATA

An encoding system may include a video source that captures video image, a video coder, and a controller to manage operation of the system. The video coder may encode the video image into encoded video data using a plurality of subgroup parameters corresponding to a plurality of subgroups of pixels within a group. The controller may set the subgroup parameters for at least one of the subgroups of pixels in the video coder, based upon at least one parameters corresponding to the group. A decoding system may decode the video data based upon the motion prediction parameters.
