Claim Text:
1. A method for decoding a coded video sequence comprising: receiving a video syntax set that includes information applicable to said coded video sequence; determining, based on a flag included in said video syntax set, whether a scalability dimension identifier is implicitly signaled; wherein said scalability dimension identifier specifies a scalability dimension of a particular layer of said coded video sequence, the scalability dimension being one of multiple types, including a spatial type and a quality type; in response to determining that the scalability dimension identifier is implicitly signaled, deriving the scalability dimension identifier from a network abstraction layer (NAL) unit header; decoding a base layer of a picture in the video sequence; decoding an enhancement layer based on the scalability dimension; and generating a picture to be displayed based on the base layer and the enhancement layer.
