Abstract
A restricted syntax range per layer in a multi-layer video coding scheme prevents inter-layer conflicts. In one embodiment, adaptive loop filtering sets defined in an adaptive parameter set are distinct in the multiple layers. In another embodiment, a layer identification is also used to uniquely identify the adaptation parameter set. In a related embodiment, a high-level syntax flag indicates whether a layer is independent of other layers.
