ADAPTIVE SYNTAX GROUPING AND COMPRESSION IN VIDEO DATA

摘要

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.

1. A system comprising:
a receiver receiving encoded video data; a video decoder decoding the encoded video data using a plurality of subgroup parameters corresponding to a plurality of subgroups of pixels within a group; and a controller setting the subgroup parameters for at least one of the subgroups of pixels in the video decoder, based upon at least one parameters corresponding to the group, wherein the encoded video data does not include the subgroup parameters for the at least one of the subgroups of pixels but includes the subgroup parameters for at least one other of the subgroups of pixels.
