摘要

PROBLEM TO BE SOLVED: To provide a method relating to video encoding which advantageously includes the coding cost for motion vectors into mode decision, thereby enhancing the quality of the selection of the mode, uses an L1 norm in the decision, thereby advantageously reducing the computational complexity of taking the coding cost for motion vectors into the mode decision, and to provide an apparatus relating to the video encoding.;SOLUTION: The method for selecting the encoding mode of a macroblock in a video encoder comprises: searching a motion for selecting the motion vector; determining a residual error of the motion vector by a plurality of macroblock modes; evaluating the coding cost from the motion vector for at least a portion of the plurality of macroblock modes; and selecting the mode for encoding the macroblock on the basis of both the residual error and the coding cost associated with the mode.;COPYRIGHT: (C)2005,JPO&NCIPI
