摘要： Disclosed is a method for decoding an image block. The method comprises a step of decoding an image block of a first layer based on a corresponding block of a second layer encoded with an intra mode, wherein a first area is formed with pixels, which are adjacent to a corner pixel positioned in the corresponding block in a diagonal direction and extend in vertical and horizontal directions away from the corresponding block, and data are padded in the first area based on the corner pixel and the pixels positioned in the first area and at least one of first and second blocks, which are simultaneously adjacent to the corresponding block and encoded with the intra mode. Accordingly, a reference block required when a macro block is encoded in an intra base mode or when a macro block encoded in the intra base mode is decoded has more precise values, thereby enabling improvement of a coding efficiency.

A value for vector refinement information of an image block present in a frame in an enhanced layer, which represents the difference between a position pointed to by a motion vector of the image block and a position pointed to by a scaled motion vector obtained by scaling a motion vector of a corresponding block in a temporally coincident frame in a bitstream of the base layer by half of the ratio of the enhanced layer picture size to the base layer picture size, is selected from 8 values allocated to 8 quarter-pixels surrounding the position pointed to by the scaled motion vector, and the vector refinement information having the selected value is recorded.

摘要： A method for encoding video signals by inverse motion compensated temporal filtering where video frames of a base layer are used to encode video frames of an enhanced layer into predicted images. For each image block in an arbitrary frame in an enhanced layer frame sequence, an area including a block, which is present in a base layer frame temporally coincident with the arbitrary frame and is at the same position as the image block, is enlarged according to the ratio between screen sizes of the two layers. A reference block most highly correlated with the image block is searched for in the enlarged area in the temporally coincident base layer frame through motion estimation and is used to obtain pixel difference values and a motion vector of the image block for encoding the image block into a predicted image, thereby improving coding efficiency.

摘要： A method and apparatus for encoding/decoding a video signal according to an MCTF coding scheme is provided. Not only pictures, which are to be converted into L pictures, but also pictures, which are to be converted into H pictures, at the current temporal decomposition level are used as candidates for a reference picture for coding a current picture into a predictive image. A previous picture, which has already been converted into an H picture, can also be used as a reference picture for converting the current picture into an H picture. Using the previous picture as the reference picture increases MCTF coding efficiency if the previous picture has an image most highly correlated with that of the current picture.

摘要： A method and apparatus for encoding/decoding a video signal according to a scalable MCTF coding scheme is provided. When a video signal is encoded through a temporal decomposition procedure, information regarding a motion vector of an image block in an H frame in a frame sequence belonging to level L of the temporal decomposition procedure is recorded using information based on a motion vector of a block spatially co-located with the image block and present in an H frame belonging to level N (higher than the level L) of the temporal decomposition procedure. When the two motion vectors of the image block and the spatially co-located block are similar, the amount of coded motion vector information can be reduced, thereby increasing MCTF coding efficiency.
