摘要： There are provided methods and apparatus for edge-based spatio-temporal filtering. An apparatus for filtering a sequence of pictures includes a spatial filter (110, 190), a motion compensator (130), a deblocking filter (140), and a temporal filter (150). The spatial filter (110, 190) is for spatially filtering a picture in the sequence and at least one reference picture selected from among previous pictures and subsequent pictures in the sequence with respect to the picture. The motion compensator (130), in signal communication with the spatial filter, is for forming, subsequent to spatial filtering, multiple temporal predictions for the picture from the at least one reference picture. The deblocking filter (140), in signal communication with the motion compensator, is for deblock filtering the multiple temporal predictions. The temporal filter (150), in signal communication with the deblocking filter, is for temporally filtering the multiple temporal predictions and combining the multiple temporal predictions to generate a noise reduced version of the picture.

摘要： There are provided methods and apparatus for weighted prediction in scalable video encoding and decoding. A scalable video encoder includes an encoder (100) for encoding a block in an enhancement layer of a picture by applying a weighting parameter to an enhancement layer reference picture. The weighting parameter used to encode the block in the enhancement layer is adaptively selected from between a weighting parameter applied to a lower layer reference picture to encode a block in the lower layer of the picture and a different weighting parameter applicable in the enhancement layer. The block in the enhancement layer corresponds to the block in the lower layer. The enhancement layer reference picture corresponds to the lower layer reference picture.

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： A method and apparatus are provided for encoding video signal data for transmission in a network. The method includes the step of encoding the video signal data at a variable bit rate using at least one of a prioritized structure or a scalable coding structure to obtain a bitstream having a base layer and an enhancement layer. The encoding step encodes the video signal data such that a base layer bitrate is constrained (420) to be less than or equal to a first value over a first time interval, and all of the bitstream, including the base layer and the enhancement layer, is constrained (425) to a bitrate less than or equal to a second value over a second time interval.
