EXHAUSTIVE SUB-MACROBLOCK SHAPE CANDIDATE SAVE AND RESTORE PROTOCOL FOR MOTION ESTIMATION

摘要

Systems, devices and methods are described including using a motion search engine of a video encoder to obtain search results for a motion predictor where the search results include a best motion vector result for each of a set of macroblock and/or sub-macroblock shape candidates of a source macroblock. The engine may then provide the search results including motion vector results for all the shape candidates as output to a motion search controller. The controller may then provide the first search results back to the search engine when the controller requests that the engine obtain second search results for another motion predictor. When doing so, the engine may use the first search results as initial conditions for performing a motion search using the other motion predictor.
