Abstract
A digital video encoder system having a motion estimation processor, and an interface to the motion estimation processor. The motion estimation processor includes a reference memory interface, and inverse quantization processor, an inverse discrete cosine transform processor, and a motion estimation processor unit including a hierarchal search unit. The motion estimation processor is utilized generating temporally compressed datastreams, that is, I-P and I-P-B datastreams.
