Abstract

A method of coding video data can include receiving video information associated with a reference layer, an enhancement layer, or both, and generating a plurality of inter-layer reference pictures using a plurality of inter-layer filters and one or more reference layer pictures. The generated plurality of inter-layer reference pictures may be inserted into a reference picture list. A current picture in the enhancement layer may be coded using the reference picture list. The inter-layer filters may comprise default inter-layer filters or alternative inter-layer filters signaled in a sequence parameter set, video parameter set, or slice header.
