Smoothing of difference reference picture
An apparatus for coding video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit stores difference video information associated with a difference video layer of pixel information derived from a difference between an enhancement layer and a corresponding base layer of the video information. The processor determines a value of a video unit based on a reference video unit or spatial neighboring video unit within the difference video layer and applies a smoothing filter to the reference video unit or spatial neighboring video unit.
