    Abstract: Decomposing a value range of the respective syntax elements into a sequence of n partitions with coding the components of z laying within the respective partitions separately with at least one by VLC coding and with at least one by PIPE or entropy coding is used to greatly increase the compression efficiency at a moderate coding overhead since the coding scheme used may be better adapted to the syntax element statistics. Accordingly, syntax elements are decomposed into a respective number n of source symbols si with i=1 . . . n, the respective number n of source symbols depending on as to which of a sequence of n partitions into which a value range of the respective syntax elements is sub-divided, a value z of the respective syntax elements falls into, so that a sum of values of the respective number of source symbols si yields z, and, if n>1, for all i=1 . . . n−1, the value of si corresponds to a range of the ith partition.

    Abstract: The signalization of the inter-layer dependencies between layers of a multi-layered data stream is described. A good compromise between a too intensive restriction of the potential diversity of inter-layer dependencies on the one hand and a too complex signaling of the inter-layer dependencies on the other hand has been found by describing the inter-layer dependencies by way of a first inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by a base layer-ID and a second inter-dependency syntax structure indicating inter-dependencies between pairs of different values representable by an extension layer-ID, the base layer ID and extension layer ID indexing the layers the portions of the multi-layer data stream are associated with. In accordance with this concept, emphasis may be shifted between increased diversity of the signalizable inter-layer dependencies on the one hand and reduced side-information overhead for signaling the inter-layer dependencies on the other hand.

    Abstract translation: 描述了多层数据流的层之间的层间依赖性的信令化。 一方面，对层间依赖性的潜在多样性的过度强化限制与另一方面的层间依赖性的太复杂的信令之间的良好妥协已经通过以下方式来发现：层间依赖性 第一相互依赖性语法结构，指示由基本层ID和第二相互依赖性语法结构表示的不同值的对之间的相互依赖性，其指示由扩展层ID表示的不同值的对之间的相互依赖性，所述基本层 ID和扩展层ID索引多层数据流的部分相关联的层。 根据这个概念，一方面可以在增加的信令化层间依赖性的多样性之间移动重点，另一方面可以减少信令层间依赖性的侧信息开销。

    Abstract: An interleaved multi-layered video data stream with interleaved decoding units of different layers is provided with further timing control information in addition to the timing control information reflecting the interleaved decoding unit arrangement. The additional timing control information pertains to either a fallback position according to which all decoding units of an access unit are treated at the decoded buffer access unit-wise, or a fallback position according to which an intermediate procedure is used: the interleaving of the DUs of different layers is reversed according to the additionally sent timing control information, thereby enabling a DU-wise treatment at the decoder's buffer, however, with no interleaving of decoding units relating to different layers. Both fallback positions may be present concurrently. Various advantageous embodiments and alternatives are the subject of the various claims attached herewith.

    Abstract translation: 除了反映交织的解码单元布置的定时控制信息之外，还提供了具有不同层的交错解码单元的交错多层视频数据流。 另外的定时控制信息属于在解码缓冲存取单元处理接入单元的所有解码单元的回退位置或使用中间过程的回退位置的情况下的DU的交错 根据另外发送的定时控制信息来反转不同的层，从而能够在解码器的缓冲器处进行DU处理，而不会对与不同层相关的解码单元进行交织。 两个回退头寸可能同时出现。 各种有利的实施例和替代方案是本文所附的各种权利要求的主题。
