PERFORMING VIDEO ENCODING MODE DECISIONS BASED ON DOWN-SCALED MACROBLOCK TEXTURE COMPLEXITY

摘要

A method and apparatus are described for performing video encoding mode decisions in a video transcoding system. A down-scaled frame may be received that includes at least one macroblock. The down-scaled frame may be associated with a full-scale frame having a plurality of macroblocks that have been downsampled. A weighting factor and a distance measure factor may be determined for each of the macroblocks in the full-scale frame. Predicted blocks may be generated based on the weighting and distance measure factors.

1. A method of performing video encoding mode decisions, the method comprising:
receiving a down-scaled frame including at least one macroblock, wherein the down-scaled frame is associated with a full-scale frame having a plurality of macroblocks that have been downsampled; determining a weighting factor for each of the macroblocks in the full-scale frame; determining a distance measure factor for each of the macroblocks in the full-scale frame; and generating predicted blocks based on the weighting and distance measure factors.
