Patent ID: 7702016

Claim:
A computer-implemented process for compressing video data comprising sequential sets of contemporaneous video frames wherein the video frames in a set depict substantially the same scene from different viewpoints arranged in a grid of viewpoints, and each frame of which is represented by at least a main layer and a boundary layer, said process comprising: using a computer to perform the following process actions: designating one or more keyframes for each set of contemporaneous frames such that each designated keyframe in any one set of contemporaneous frames has a viewpoint among the different viewpoints arranged in a grid of viewpoints that is the same as a designated keyframe in all the other sets of contemporaneous frames; and for each set of contemporaneous video frames in time sequence order, compressing the main layer of each keyframe using an inter-frame compression technique; compressing the main layer of each non-keyframe using a spatial prediction compression technique; and compressing the boundary layer of each frame using an intra-frame compression technique.
