1. A digital video encoder, comprising:
one or more memories; and
digital signal processing circuitry, which, in operation:
segments frames in a digital video sequence into object regions and background regions;
generates object motion and appearance parameters based on segmented object regions;
categorizes blocks in background P frames regions into edge blocks and non-edge blocks; and
generates an auto regressive background model based on the non-edge blocks of the segmented background regions.
