Abstract:
1. A method of coding scalable video data having at least a first and a second layer, said layers comprising one or more of a spatial, quality, and fine granularity scalability (FGS) enhancement layer and said first and second layers together comprising at least two pictures, the method comprising: identifying the first layer using a first value of a dependency identifier and the second layer using a second value of the dependency identifier, the dependency identifier indicating decoding dependency such that for a coded picture with a certain value of dependency identifier only reference pictures with the same value of the dependency identifier are usable for motion compensated inter prediction; identifying said reference pictures within the identified first and second layers using a second identifier; and coding a value of the second identifier for pictures in the first and the second layer, wherein said value is increased by one relative to the value of the second identifier of a previous reference picture in decoding order in each of said first and second layer.
