Abstract
An apparatus used for video encoding MPEG compliant digital visual images, having multiple MPEG encoders used in the motion estimation function. The search capabilities used in the motion estimation function of a single MPEG encoder are extended beyond its design limitations as a result of utilizing more than one MPEG encoder. The utilization of multiple encoders effectively creates the capability for a user to specify a wider search window than what is available in a single encoder configuration. The computational search efficency associated with searching the wider window is not adversely affected as a consequence of the multiple processors subdividing the extended window and analyzing each subdivision in parallel.
