摘要： A raw byte sequence payload describing a picture in slices, WPP substreams or tiles and coded using context-adaptive binary arithmetic coding is subdivided or chopped into tranches with continuing the context-adaptive binary arithmetic coding probability adaptation across tranche boundaries. By this measure, tranche boundaries additionally introduced within slices, WPP substreams or tiles do not lead to a reduction in the entropy coding efficiency of these elements. On the other hand, however, the tranches are smaller than the original slices, WPP substreams or tiles and accordingly they may be transmitted earlier, i.e. with lower delay, than the un-chopped original entities, i.e. slices, WPP substreams or tiles. In accordance with another aspect, which is combinable with the first aspect, substream marker NAL units are used within a sequence of NAL units of a video bitstream in order to enable a transport demultiplexer to assign data of slices within NAL units to the corresponding substreams or tiles so as to be able to, in parallel, serve a multithreaded decoder with the corresponding substreams or tiles.
摘要翻译：使用上下文自适应二进制算术编码将片段中的图像，WPP子流或块并且使用上下文自适应二进制算术编码进行编码的原始字节序列有效载荷被细分或切割成具有跨越边界的上下文自适应二进制算术编码概率适应的阶段。通过这种措施，在切片，WPP子流或瓦片中另外引入的分支边界不会导致这些元素的熵编码效率的降低。然而，另一方面，这些段落比原始片段，WPP子流片或片段小，因此它们可以比未切割的原始实体（即片，WPP子流或片）更早发送，即具有较低的延迟。根据可与第一方面组合的另一方面，在视频比特流的NAL单元的序列内使用子流标记NAL单元，以便使传输解复用器能够将NAL个单元内的片段的数据分配给相应的子流或以便能够并行地为具有相应子流或瓦片的多线程解码器服务。

摘要： The handling of scalable data streams by network entities is rendered less complex by, in the data stream, accompanying packets which actually carry data by packets of a different packet type which have a scalability axes descriptor defining the number of scalability axes and a semantic meaning thereof. By this measure, it is sufficient if the data carrying packets comprise an operation point identifier identifying an operation point associated with a respective packet within the scalability space spanned by the scalability axis. By this measure, the packet operation point identifiers provide enough information to a network entity so as to associate these packets with their operation point in the scalability space provided the network entity has access to this scalability axes descriptor provided by the packet of the predetermined packet type. In another aspect, the handling of scalable data streams by network entities is rendered more efficient by conveying level and/or profile descriptors using packets other than the data carrying packets, with profile and/or level descriptors being divided up into a first set explicitly signaling the definition of the available coding option set and/or available syntax element value range for a respective operation point, and a second set of profile and/or level descriptors which signal the definition of the available coding option set and/or available syntax element value range for their respective operation points by reference another profile and/or level descriptor.
摘要翻译：在数据流中，通过网络实体对可伸缩数据流的处理变得不那么复杂，其伴随分组实际上通过具有可伸缩轴描述符的不同分组类型的分组来传送数据，所述可伸缩轴描述符定义了可伸缩轴的数量及其语义含义。通过这种措施，携带数据包的数据包括操作点标识符就足够了，该操作点标识符标识与可伸缩性轴所跨越的可伸缩性空间内的相应数据包相关联的操作点。通过这种措施，分组操作点标识符向网络实体提供足够的信息，以便在可扩展性空间中将这些分组与它们的操作点相关联，只要网络实体能够访问由预定分组类型的分组提供的该可伸缩轴描述符。在另一方面中，通过使用除了承载数据包的数据之外的分组来传送级别和/或简档描述符，由网络实体对可伸缩数据流的处理变得更加有效，其中简档和/或级别描述符被划分为第一组显式信令用于相应操作点的可用编码选项集合和/或可用语法元素值范围的定义以及用信号通知可用编码选项集合的定义和/或可用语法元素值的第二组简档和/或等级描述符通过参考另一个简档和/或等级描述符来确定它们各自的操作点的范围。

摘要： Parallel processing concepts such as wavefront parallel processing, are realized with a reduced end-to-end delay by giving up the usual slice concept according to which slices are either coded/decoded completely independent from areas of the picture outside of the respective slice, or at least independent from areas outside the respective slice as far as the entropy coding is concerned, namely in favor of slices of different modes, namely ones called dependent slices which allow for interdependencies across slice boundaries, and others which do not, called normal slices, for example. Combined with the aspect or not, WPP processing concept is made more efficiently by using the slices' start syntax portions to locate WPP entry points.
