Abstract:
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.

Claim (Index 1):
A device configured to process a data stream representing video data, comprising:\n a receiver configured to receive a multi-layered data stream that represents a video coded into a plurality of layers and includes a plurality of packets, each of which is associated with one of the plurality of layers; and a processor, which when executes instructions, is configured to: for each of the plurality of packets,\n read a base layer-ID field from the multi-layered data stream, the base layer-ID field including a first sub-field and a second sub-field, \n check as to whether the first sub-field of the base layer-ID field fulfills a predetermined criterion, \n responsive to a determination that the first sub-field of the base layer-ID field fulfills the predetermined criterion, read an extension layer-ID field from the multi-layered data stream, and derive an extension value using the extension layer-ID field so that the extension value lies within a first subset of a domain of extension values, \n responsive to a determination that the first sub-field of the base layer-ID field does not fulfill the predetermined criterion, set an extension value to a value disjoint to the first subset of the domain of extension values, \n derive a cluster value based on the second sub-field and a domain of cluster values, and \n determine an index value for the layer with which the respective packet is associated based on the cluster and extension values, and \n reconstruct at least a portion of the video based on inter-layer prediction using inter-layer prediction dependencies according to the index values of the plurality of layers and prediction residual extracted from the plurality of packets.
