摘要： In PIPE coding, where alphabet symbols are distributed among a plurality of specialized entropy en/decoders according to their probability distribution estimate, a categorizing stage is provided where source symbols to be encoded are sub-divided into a first substream which is subject to VLC coding, and a second substream which is subject to PIPE coding. By this measure, source symbols having an appropriate symbol probability distribution, i.e. a probability distribution suitable for being efficiently coded by means of VLC coding without the deficiencies outlined above in the introductory portion of the specification of the present application, may be categorized as VLC coded symbols whereas other symbols may be treated as PIPE coded symbols and subject to PIPE coding, the coding complexity of which is higher than VLC coding, but at a better compression efficiency.

摘要： A coding efficiency increase is achieved by using a common signalization within the bitstream with regard to activation of merging and activation of the skip mode. One possible state of one or more syntax elements within the bitstream may signalize for a current sample set of a picture that the sample set is to be merged and has no prediction residual encoded and inserted into the bitstream. A common flag may signalize whether the coding parameters associated with a current sample set are to be set according to a merge candidate or to be retrieved from the bitstream, and whether the current sample set of the picture is to be reconstructed based on a prediction signal depending on the coding parameters associated with the current sample set, without any residual data, or to be reconstructed by refining the prediction signal depending on the coding parameters associated with the current sample set by means of residual data within the bitstream.

摘要： A higher coding efficiency for coding a significance map indicating positions of significant transform coefficients within a transform coefficient block is achieved by the scan order by which the sequentially extracted syntax elements indicating, for associated positions within the transform coefficient block, as to whether at the respective position a significant or insignificant transform coefficient is situated, are sequentially associated to the positions of the transform coefficient block, among the positions of the transform coefficient block depends on the positions of the significant transform coefficients indicated by previously associated syntax elements. Alternatively, the first-type elements may be context-adaptively entropy decoded using contexts which are individually selected for each of the syntax elements dependent on a number of significant transform coefficients in a neighborhood of the respective syntax element, indicated as being significant by any of the preceding syntax elements. Even alternatively, the values are scanned in subblocks, and contexts are selected based on subblock statistics.

摘要： A video decoder using motion-compensated prediction comprises a predictor configured to predict a first subset of parameters of a plurality of motion parameters, defining the motion-compensated prediction of a predetermined region of a picture of a video, to obtain a prediction for the first subset. The video decoder further comprises a reconstructor configured to reconstruct the first subset of parameters from the prediction of the first subset and residual information for the first subset contained in a data stream, to obtain a reconstruction of the first subset. The predictor is further configured to predict a second subset of parameters of the plurality of motion parameters, being disjoint from the first subset, using the reconstruction of the first subset.
