A method and apparatus for performing a predictive motion search in a video encoder
system using motion vectors representing the difference in coordinates of a macroblock
of data in a current frame of video data and coordinates of a related macroblock
of data in a reference frame of video data. A plurality of motion vector predictors
is obtained where the motion vector predictors represent approximations of possible
motion vectors for a current macroblock. A search pattern is defined. Each motion
vector predictor of the plurality of motion vector predictors is searched around
using the search pattern. A final motion vector is then determined.
