Motion vector difference coding extension for enhancement layer
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 pixel accuracy of motion predictor information, determines a motion vector based on the pixel accuracy of the motion predictor information, and determines a value of a video unit based at least in part on the motion vector.
