摘要： In one embodiment of a method of decoding a first frame sequence layer, at least one motion vector of an image block in a frame of the first frame sequence layer is determined based on a motion vector for an image block in a frame of a second frame sequence layer and a temporal difference between the frame in the second frame sequence layer and the frame in the first frame sequence layer. Here, the second frame sequence layer does not include a frame temporally coincident with the frame of the first frame sequence layer. The image block in the frame of the first frame sequence layer is decoded based on the determined motion vector.

摘要： During scalable MCTF encoding of a video signal divided into base and enhanced layers, a first derivative vector of a first motion vector, obtained through motion estimation, of an image block in an arbitrary frame in the enhanced layer is obtained based on the product of a derivation factor and a scaled one of a motion vector of a first block in a base layer frame not temporally coincident with the arbitrary frame. A second derivative vector of a second motion vector, obtained through motion estimation, of the image block is obtained based on the scaled vector and the first motion vector. Information allowing bidirectional motion vectors of the image block to be obtained from the derivative vectors is recorded in motion vector information of the image block. Using the correlation between motion vectors of temporally adjacent frames in different layers reduces the amount of coded motion vector data.

摘要： A method and apparatus for scalably encoding and decoding a video signal is provided. During encoding, prediction is performed on an image block to produce residual data of the image block, and the residual data of the image block is selectively coded into a residual difference from residual data of a block of a base layer, which spatially corresponds to the image block and is present in a base layer frame temporally coincident with a frame including the image block. Whether to code the image block into the residual difference is determined based on the difference between coding information (motion vectors or block pattern (CBP) information) of the image block and coding information of the corresponding block. Separate information indicating whether or not the image data has been coded into the residual difference is not transmitted to the decoder even if the image data has been coded into the residual difference.

摘要： A method for encoding and decoding a video signal in a scalable Motion Compensated Temporal Filtering (MCTF) scheme is provided. A video signal is encoded by adaptively weighting reference pictures of a current frame based on temporal positions of the reference pictures relative to the current frame in MCTF prediction and update procedures, and such encoded video signal is decoded accordingly. Efficient weighting of reference pictures based on their temporal positions in the prediction and update procedures improves the compression efficiency of the video signal.
