摘要： A better rate distortion ratio is achieved by making interrelationships between coding parameters of different planes available for exploitation for the aim of redundancy reduction despite the additional overhead resulting from the necessity to signal the inter-plane prediction information to the decoder. In particular, the decision to use inter plane prediction or not may be performed for a plurality of planes individually. Additionally or alternatively, the decision may be done on a block basis considering one secondary plane.

To this end, for the simply connected regions, a predetermined relative locational relationship is defined enabling an identifying, for a predetermined simply connected region, of simply connected regions within the plurality of simply connected regions which have the predetermined relative locational relationship to the predetermined simply connected region. Namely, if the number is zero, a merge indicator for the predetermined simply connected region may be absent within the data stream. In accordance with even further embodiments, a spatial sub-division of an area of samples representing a spatial sampling of the two-dimensional information signal into a plurality of simply connected regions of different sizes by recursively multi-partitioning is performed depending on a first subset of syntax elements contained in the data stream, followed by a combination of spatially neighboring simply connected regions depending on a second subset of syntax elements within the data stream being disjoined from the first subset, to obtain an intermediate sub-division of the array of samples into disjoint sets of simply connected regions, the union of which is the plurality of simply connected regions. The intermediate sub-division is used when reconstructing the array of samples from the data stream.

摘要： A more efficient way of addressing different bit-depths, or different bit-depths and chroma sampling format requirements is achieved by using a low bit-depth and/or low-chroma resolution representation for providing a respective base layer data stream representing this low bit-depth and/or low-chroma resolution representation as well as for providing (134) a higher bit-depth and/or higher chroma resolution representation so that a respective prediction residual may be encoded in order to obtain a higher bit-depth and/or higher chroma resolution representation. By this measure, an encoder (100) is enabled to store a base-quality representation of a picture or a video sequence, which can be decoded by any legacy decoder or video decoder, together with an enhancement signal for higher bit-depth and/or reduced chroma sub-sampling, which may be ignored by legacy decoders or video decoders.

摘要： A basic idea of the present application was that refinement layers showing an improved rate/distortion performance may be achieved by accompanying residual information refinement information with refined motion information. In particular, it has been recognized that for small maximum-rates a coarse motion information involving less bits for representing the motion information' in the bit-stream leads to good rate/distortion performance. However, with increasing maximum-rates, merely refining the encoding of the texture information relative to the coarse motion information does not lead to optimal rate-distortion performance for representing the respective refinement layer. Rather, more bits should be spent for the motion information in order to refine the motion' information for achieving a better rate/distortion performance for higher for maximum-bit-rates. By this measure, a significantly improved coding efficiency is achieved.
摘要翻译：本申请的基本思想是可以通过伴随具有精细运动信息的残留信息细化信息来实现显示改进的速率/失真性能的细化层。特别地，已经认识到，对于小的最大速率，涉及用于表示比特流中的运动信息的较少位的粗略运动信息导致良好的速率/失真性能。然而，随着最大速率的增加，相对于粗略运动信息仅改进纹理信息的编码不会导致用于表示相应细化层的最佳速率失真性能。相反，应该花费更多的比特用于运动信息，以便细化运动信息，以获得更高的速率/失真性能，以达到最大比特率。通过这种措施，可以显着提高编码效率。

摘要： Apparatus for decoding a predetermined block (18) of a picture using intra-prediction, configured to read, from the data stream (12), a mode index (200), the mode index pointing to one out of a list (204) of matrix-based intra-prediction modes. Additionally, the apparatus is configured to predict samples (108) of the predetermined block (18) by computing a matrix- vector product (206) between an input vector (102) derived from reference samples (17) in a neighborhood of the predetermined block (18) and a prediction matrix (19) associated with the matrix-based intra-prediction mode (k) pointed to by the mode index (200) and associating components (210) of an output vector (208) obtained by the matrix-vector product (206) onto sample positions (104) of the predetermined block. For each matrix-based intra-prediction mode, all entries of the prediction matrix (19) associated with the respective matrix-based intra-prediction mode are represented by a fixed point representation of a predetermined bit-depth, the predetermined bit-depth being equal for the matrix-based intra- prediction modes. Furthermore, the apparatus is configured to, for each matrix-based intra-prediction mode, compute the matrix-vector product (206) between the input vector (102) and the prediction matrix (19) associated with the respective matrix-based intra-prediction mode (k) by performing, for each component of the output vector, a right shift at a number of bits which is equal for the matrix-based intra-prediction modes.
