Coding of digital video with high motion content |
摘要 |
Methods for coding the current frame of a video data bit stream are provided. Methods include, for example, creating and maintaining a global codebook of historic values for the macroblocks of previous frames; searching entries in the global codebook to find the best estimation of the current frame and calculate a measure of the difference between values for the two macroblocks; comparing the effectiveness of the estimation macroblock provided by the global codebook entry to the estimation provided by a motion compensation scheme; choosing the best estimation method and coding the current frame; and updating the global codebook based on the new coded macroblock. |
