摘要： Decoder retrieval timing information, ROI information and tile identification information are conveyed within a video data stream at a level which allows for an easy access by network entities such as MANEs or decoder. In order to reach such a level, information of such types are conveyed within a video data stream by way of packets interspersed into packets of access units of a video data stream. In accordance with an embodiment, the interspersed packets are of a removable packet type, i.e. the removal of these interspersed packets maintains the decoder's ability to completely recover the video content conveyed via the video data stream.

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.

摘要： 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 embodiments attached herewith.

摘要： A signaling of at least one characteristic for layers of a multi-layered video signal such as, for example, for each layer the indication of dependent layers to which the respective layer directly relates via inter-layer prediction, or the signaling of the afore-mentioned second inter-dependency syntax structure, is described. A maximum syntax element is signaled within the multi-layered video signal to indicate a maximally used value of an extension layer-ID field of the packets of the multi-layered video signal, the scope of the maximum syntax element being, for example, a predetermined portion of the multi-layered video signal extending, for example, across several portions of the multi-layered video signal. Accordingly, it is feasible for devices such as decoders or network elements receiving the multi-layered video signal to gain, for a relatively large predetermined portion of the multi-layered video signal, knowledge about the actually consumed portion of the possible domain of possible values signalizable by the extension layer-ID field and the at least one characteristic does not need to be signaled for each combination of base layer-ID field value and extension layer-ID field value, but rather it is sufficient to signal the at least one characteristic for a maximum number of layers determined based on the maximum assumed value. Accordingly, the at least one characteristic does not need to be transmitted/signalized for layers with a layer ID, the extension layer-ID of which does not occur within the predetermined portion of the multi- layered video signal. Beyond this, in accordance with a further embodiment, the knowledge of the maximally assumed value may be used to reduce the side information overhead for signaling the layer-ID of each portion, i.e. for reducing the bits needed to signal the extension layer-ID field within the multi-layered video signal's packets.
摘要翻译： 描述层ID的信令，其中多层视频信号的每个分组与哪个分组相关联。 特别地，实现了一种用于发信号通知该层关联的有效方式，但仍保持与编解码器的向后兼容性，根据该编解码器，基本层ID字段的某个值被限制为不可扩展的，例如基本层ID值0 在基层ID字段中。 除了针对该不可扩展的基本层ID值特别地规避这一限制之外，多层数据流的部分的层ID可以以可扩展的方式通过将基本层ID字段划分为 第一子场和第二子场：每当基本层ID字段的第一子字段满足预定标准时，提供扩展层ID字段，并且如果基本层ID-ID字段的第一子字段 ID字段不满足预定标准，省略了扩展层ID字段。

摘要： 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: for example, calling the sets of layers having a common base-layer ID, respectively, "clusters", the same second inter-dependency syntax structure may be used to regulate the inter-dependencies within all clusters and between all clusters related to each other via the first inter-dependency syntax structure, separately. Alternatively, two instantiations of the second inter-dependency syntax structure may be used to describe the inter-dependencies of the layers within the clusters on the one hand and between the layers of different clusters, on the other hand. Irrespective of the emphasis placed towards increased diversity or reduced side information overhead, the inter-dependency signaling concept results in keeping the signaling overhead low.
