摘要： There are provided methods and apparatus for determining expected distortion in decoded video blocks. An apparatus includes a distortion calculator for calculating an expected distortion for an image block, included in a picture of a video sequence and sent over a lossy channel, using a motion vector for the image block when the motion vector has a non-integer value. The distortion calculator calculates the expected distortion based upon a propagated distortion of at least two neighboring integer pixel positions in a reference picture with respect to the motion vector having the non-integer value. The image block is coded in an inter mode or a SKIP mode.

摘要： There is provided a compression method for handling local brightness variation in video. The compression method estimates the weights from previously encoded and reconstructed neighboring pixels of the current block in the source picture and their corresponding motion predicted (or collocated) pixels in the reference pictures. Since the information is available in both the encoder and decoder for deriving these weights, no additional bits are required to be transmitted.

摘要： An encoder, a decoder, corresponding encoding and decoding methods, video signal structure, and storage media are provided for scalable video encoding and decoding. A scalable video encoder includes an encoder (100) for encoding a picture to form a base layer bitstream and an enhancement layer bitstream. The base layer bitstream and the enhancement layer bitstream are formed by partitioning the picture into a plurality of image blocks, grouping the plurality of image blocks into one or more slice groups in the base layer bitstream and into two or more slice groups in the enhancement layer bitstream, encoding all of the one or more slice groups in the base layer bitstream and less than all of the two or more slice groups in the enhancement layer such that at least one slice group from among the two or more slice groups is intentionally un-encoded in the enhancement layer bitstream, encoding a syntax element in a header to indicate the at least one intentionally un-encoded slice group in the enhancement layer.

摘要： Methods and apparatus for implementing a reduced cost HDTV/SDTV video decoder are disclosed. The described joint video decoder is capable of decoding HDTV pictures at approximately the resolution of standard definition television pictures and can be used to decode HDTV and/or SDTV pictures. The described video decoder may be used as part of a picture-in-picture decoder circuit for providing picture-in-picture capability without providing multiple full resolution video decoders. The reduction in decoder circuit complexity is achieved through the use of a plurality of data reduction techniques including the use of a preparser, downsampling, and truncating pixel values.
