    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: 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.
