Multiple encoder architecture for extended search |
摘要 |
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.
