Claim Text:
1. A method for decoding a base layer conforming to a second coding technology from a hybrid scalable bitstream, the hybrid scalable bitstream comprising the base layer conforming to the second coding technology and at least one enhancement layer conforming to a first coding technology, wherein the first and second coding technology are not the same, and wherein both first and second coding technologies use Network Abstraction Layer (NAL) units, the method comprising: extracting at least one second NAL unit conforming to the second coding technology from a first NAL unit of the hybrid bitstream identified by a pre-determined value of a nal_unit_type indicating the NAL unit is an encapsulation NAL unit, and decoding, in a decoding device compliant with the second coding technology, the at least one second NAL unit, wherein the second coding technology is identified by a syntax element in a Video Parameter Set (VPS); and wherein both the first and second coding technology support temporal layers, and the VPS further includes information indicative of a derivation of the temporal layer associated with the second NAL unit from the temporal layer associated with the first NAL unit.
