Abstract (en)
[origin: WO2009073824A1] 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 a maximum data rate of a communication channel between a server and a client; dynamically selecting a tile size for encoding a sequence of images based on the detected maximum data rate; logically subdividing each of the sequence of images into a plurality of tiles sized according to the selected tile size, each of the tiles having a defined position within each of the sequence of images; encoding each tile within each image of the sequence of images using a first compression format or a second compression format, wherein a tile at a particular position of a first image in the sequence of images is encoded using the first compression format.
