摘要： A method and system of transform-based encoding, decoding, and bitstream generation of digital video content. The digital video content comprises a stream of pictures, slices, or macroblocks which can each be intra, predicted or bi-predicted pictures. The pictures, slices, or macroblocks comprise blocks of pixels. The method comprises scanning frequency coefficients from each of the block's two dimensional array of frequency coefficients in a manner that is vertically biased.

摘要： The present invention discloses a system and method for performing motion estimation associated with an encoder, e.g., a H.264/MPEG-4 AVC compliant encoder. For example, the method selects a motion vector centering for a current block in a search area of at least one reference picture. The method calculates a matching cost for each of a plurality of candidate motion vectors derived from the search area, and outputs at least one of the plurality of candidate motion vectors based on the matching cost associated with each of the plurality of candidate motion vectors to a main coding loop.

摘要： A block based sampling (BBS) encoding system to process an incoming video signal into a compressed video bitstream. The BBS encoding system includes a processor to determine anchor blocks in a picture from the incoming video signal. The processor is also to encode the anchor blocks in the picture, and may also encode interpolated blocks in the picture using at least one of the encoded anchor blocks. There is also a block based sampling (BBS) decoding system to decode pictures from an incoming compressed video bitstream. The BBS decoding system includes a processor to receive the incoming compressed video bitstream including anchor block coding decisions about anchor blocks in a pattern in a picture, and decode the received anchor block coding decisions to form the anchor blocks in the pattern in the picture.
