1. A device comprising:
a receiver configured to receive a multi-layered video signal composed of a sequence of packets each of which comprises a layer identification syntax element structure composed of a base layer-ID field and an extension layer-ID field;
a layer identification extender configured to
read, for a plurality of packets, a first maximum syntax element included in a first network abstraction layer (NAL) unit from the multi-layered video signal, indicating a first maximally assumed value of the extension layer-ID field of the plurality of packets,
read, for the plurality of packets, a second maximum syntax element included in a second NAL unit from the multi-layered video signal, indicating a second maximally assumed value of the base layer-ID field of the plurality of packets,
determine a maximum number of layers within a predetermined portion of the multi-layered video signal based on the first and second maximally assumed values, and
determine at least one characteristic for each of the maximum number of layers by iteratively parsing a layer characterizing syntax portion of the multi-layered video signal a number of times equal to the maximum number of layers,
wherein the device is configured to acquire a bit length of the extension layer-ID field from an explicit signaling in the multi-layered video signal, wherein the first maximum syntax element indicates the first maximally assumed value of the extension layer-ID field in units smaller than the bit length of the extension layer-ID field minus one to the power of two.
