Abstract (en)

[origin: WO2009073823A1] 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: logically subdividing each of a sequence of images into a plurality of tiles, each of the tiles having a defined position within each of the sequence of images, the defined position remaining the same between successive images; detecting motion or high scene complexity within the sequence of images occurring at each of the positions of each of the tiles; and encoding each tile within each image of the sequence of images using a specified number of bits, the number of bits selected based on the detected amount of motion at the position of each tile across the sequence of images.
