Abstract (en)
[origin: WO2009073825A1] A system and method are described below for encoding interactive low-latency video using interframe coding. For example, one embodiment of a computer-implemented method for performing video compression comprises: detecting motion or high scene complexity within a sequence of images occurring at different regions within the sequence of images; logically subdividing each of the sequence of images into a plurality of tiles, each tile having a size selected based on the amount of motion detected in a region in which the tile is positioned; and encoding one or more of the tiles within each image of the sequence of images using a first compression format and encoding the remainder of the tiles within each image of the sequence of images using a second compression format.
