Abstract
A method of rapidly generating motion vector predictions based on vertical and horizontal position categorization of macroblocks within a video object plane (VOP) for use within a video decoder or encoder. By way of example, the location of the subject macroblock is categorized vertically as either Upper_Edge or Not_Upper_Edge, and horizontally as either Left_Edge, Right_Edge, or Not_Edge. The position categories are utilized in conjunction with selected block number (Blockthrough Block) within the luminance macroblock within a decision-tree which generates three predictors MVMVand MVThe prediction rules may be implemented within hardware, software, or combinations thereof, within both video encoders and decoders, such as according to the MPEG-4, H.263, or similar standards.
