Abstract

A method and apparatus for enabling low latency compression of a stream of pictures are described. A first set of static regions of a current picture from the plurality of pictures is determined, where each region from the first set is static. A second set of regions of the current picture is determined, where the second set includes all regions of the current picture that are not included in the first set. Compression of the first set of regions is performed based on values of a first quantization parameter determined by a MAQ mechanism. The MAQ mechanism is operative to dynamically increase the compression quality of static regions. Compression of the second set of regions is performed based on values of a second quantization parameter determined by a rate control mechanism. The rate control mechanism is operative to compress the data stream according to a target bit rate.
