Claim:
1. A method for encoding a sequence of pictures, the method comprising: receiving the sequence of pictures; generating a base layer of coded pictures based on the sequence pictures; generating at least one enhancement layer of coded pictures based on the sequence of pictures; generating a video syntax set that includes information applicable to coded pictures including a flag indicating whether a scalability dimension identifier is signaled implicitly or explicitly, and wherein the scalability dimension identifier specifies a scalability dimension of a particular layer of coded pictures, the scalability dimension being one of multiple types, including: a spatial type and a quality type; generating one or more network abstraction layer (NAL) units representing the base layer and the enhancement layer; and in case the flag indicates that the scalability dimension identifier is implicitly signaled, signaling the scalability dimension identifier implicitly in a header of a NAL unit representing the enhancement layer.
