摘要： In this disclosure, a hybrid digital-analog video coding scheme is described. For a video including at least two associated sequences of frames such as a stereo video, some of the frames are digitally encoded, while the others are encoded in an analog way with reference to the digital frames. For an analog frame, a previous frame in the same sequence/view and a temporally consistent frame in another sequence/view will be encoded as digital frames. These two digital frames are used to provide side information in encoding the analog frame. At decoding side, inverse operations are performed. Such "zigzag" hybrid coding significantly improves the coding efficiency while providing robustness and good visual quality.

摘要： A signaling of the layer ID is described which each of the packets of a multi-layered video signal is associated with. In particular, an efficient way of signaling this layer association is achieved, with nevertheless maintaining the backward compatibility with codecs according to which a certain value of the base layer-ID field is restricted to be non-extendable such as base layer-ID value 0 in the base layer-ID field. Instead of circumventing this restriction specifically with respect to this non-extendable base layer-ID value, the layer-ID of portions of the multi-layer data stream is signaled in an extendable manner by sub-dividing the base layer-ID field into a first sub-field and a second sub-field: whenever the first sub-field of the base layer-ID field fulfills a predetermined criterion, an extension layer-ID field is provided, and if the first sub-field of the base layer-ID field does not fulfill the predetermined criterion, the extension layer-ID field is omitted. The aforementioned non-extendable base layer-ID value is "hidden" within the group of base layer-ID values for which the first sub-field of the base layer-ID field does not fulfill the predetermined criterion, and accordingly this non extendable base layer-ID value is not handled separately, but rendered part of the former group. Rather, if the first sub-field of the base layer-ID field fulfills the predetermined criterion, an extension value is derived from the extension layer-ID field signaled within the multi-layer data stream such that same lies within a first subset of a domain of extension values, and if the first sub-field of the base layer-ID field does not fulfill the predetermined criterion, this extension value is set to a value disjoint to the first subset of the domain of extension values. The layer which a respective portion is associated with is then indexed using the extension value as well as the cluster value which is derived from a second sub-field of the base layer ID field. All in all, no signaling efficiency has been lost despite the maintenance of the backward compatibility.
摘要翻译：描述了层ID的信令，其中多层视频信号的分组中的每一个与哪个分组相关联。特别地，实现了发送该层关联的有效方式，然而仍然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值专门地规避这种限制之外，代替多层数据流的部分的层ID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。上述不可扩展基层ID值在基层ID域的第一子字段不满足预定标准的基层ID值组内是“隐藏的”，因此该不可扩展基 layer-ID值不是单独处理，而是前面组的一部分。相反，如果基本层ID字段的第一子字段满足预定标准，则从在多层数据流内信令的扩展层ID字段导出扩展值，使得它们位于多层数据流的第一子集内扩展值的域，并且如果基本层ID字段的第一子字段不满足预定标准，则该扩展值被设置为与扩展值的域的第一子集不相交的值。然后使用扩展值以及从基本层ID字段的第二子字段导出的聚类值对相关部分相关联的层进行索引。总而言之，尽管维持向后兼容性，但信号效率没有丢失。
