Searching method and system for best matching motion vector

摘要

The invention relates generally to compression of video data and specifically to lowering at least a cost of motion information while encoding a macroblock. According to one embodiment, the present invention searches for a matching block that lowers a cost of encoding the macroblock including the cost of encoding motion information. According to another embodiment, the present invention lowers the cost of encoding the macroblock including the cost of encoding motion information at one or more stages of a multiresolution search.
