Abstract: A system for encoding and decoding a frame (also file), such as a video, graphic, media, or other frame or data, representing a real-time graphic output from a frame buffer, output by a video camera, or another file or data. The file includes frames each comprising macroblocks. Reference frame buffers (PFTs), virtual frame buffer tables (VFTBs) of equal number to the PFTs, each VFTB corresponds to a respective PFT, and respective sectors of each PFT for respective macroblocks are created. Frames of the file are encoded/decoded by successive encode/decode of macroblocks. A pointer is created in the VFBT associated with the PFT rather than encoding/decoding any matching macroblock. The pointer and its reference are relied on for each already encoded/decoded macroblock retained in the PFT. Processing, memory, bandwidth and power requirements for encoding or decoding are reduced.

Abstract: A motion vector estimation method in video encoding: First, a feature point is detected in a video frame. Next, motion estimation is performed on the feature point to obtain a motion vector of the feature point. Next, the feature point is mapped to a feature image block, and the motion vector of the feature point is used as an initial motion vector of the feature image block. Finally, a distance between each image block and the feature image block is calculated, motion estimation is performed on the image blocks in an ascending order of the distances between the image blocks and the feature image block, and an obtained motion vector of an image block is used as an initial motion vector of an image block that is adjacent to the image block and has not undergone motion estimation, until motion estimation is completed for the image blocks in the entire video frame.

Abstract: A temporal motion vector predictor is includable, together with one or more spatial motion vector predictors, in a set of motion vector predictors for a block to encode of a current frame. A method of determining the temporal motion vector predictor comprises selecting as the temporal predictor one motion vector from among motion vectors in a reference block of a reference frame different from the current frame. The reference block is a block of the reference frame collocated with the block to encode or a block of the reference frame neighboring the collocated block. The selection is based on a diversity criterion for achieving diversity among the predictors of the set. This can reduce the motion vector memory requirements with no or no significant additional coding efficiency penalty. Alternatively, even if the motion vector memory is not reduced in size, coding efficiency improvements can be achieved.
