摘要： Often hierarchical bi-directionally predicted frame structures are used for encoding a video picture sequence. The frames may consist of interlacing fields. A method for encoding interlaced video, wherein inter-prediction of fields is used and reference lists are assigned to the fields for indicating reference frames or fields, comprises that, if within such reference list a reference to another frame is included, then references to both fields of the other frame are included separately in direct sequence. Further, a temporal level is assigned to each of the frames according to their display order, and for the frames of all except one temporal level the quantization parameter is higher for one type of fields than for the other type of fields.

摘要： The invention relates to a method for coding an image data macroblock of a sequence of images presented in the form of a base layer and at least one enhancement layer. The image data macroblock to which corresponds an image data block in the base layer, called a corresponding block, belongs to the enhancement layer. The method comprises the following steps: generate, for the said image data macroblock, a prediction macroblock of image data from one block or several blocks of image data blocks of the said base layer previously coded and reconstructed, generate a macroblock of residues from the prediction macroblock and from the image data macroblock MBEL of the enhancement layer, and code the said macroblock of residues. According to the invention, the image data blocks of the said base layer are different from the corresponding block.

摘要： A method for decoding a stream of coded data to reconstruct a current block of a sequence of images is disclosed. The method comprises the steps of: reconstructing for the current block a first item of motion data from a stream of coded data, identifying a first prediction block with the first item of motion data, determining a second item of motion data by template matching, identifying a second prediction block with the second item of motion data, reconstructing the current block from the first and second prediction blocks. The step of determination of the second item of motion data is a function of the first distortion calculated between the first prediction block and the second prediction block.

摘要： The invention is made in the field of image block encoding and reconstruction. A method for reconstructing a current block of an image is described, the current block being encoded using predictive encoding of segments resulting from geometry adaptive block partitioning of said current block. After decoding encoded data comprising at least one flag and motion vectors, wherein blocks referenced by the motion vectors are used for prediction of segments of the current block, the at least one flag and an encoding order of the motion vectors in the encoded data is used for determining which of the referenced blocks exhibits a geometry that matches the geometry of the current block and for determining a segment of the determined block, wherein prior to determining the segment, the determined block is geometry adaptive block partitioned into segments from which the segment is determined for predicting one of the segments of the current block.
