Abstract: 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 video information associated with a reference layer and a corresponding enhancement layer. The processor receives a mode list associated with the enhancement layer, the mode list comprising three entities, each entity identifying a different mode for determining a value of a video unit located at a position within the enhancement layer. The processor changes the mode list when a mode associated with a co-located video unit in the reference layer is not stored as the first entity in the mode list. The co-located video unit is located at a position in the reference layer corresponding to the position of the video unit in the enhancement layer.

Abstract: An apparatus for coding video data according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video data associated with a base layer and a corresponding enhancement layer. The processor is in communication with the memory, and in a case that the video data comprises a particular mode flag, the processor determines (e.g., predicts) an enhancement layer block in the enhancement layer of the video data based at least in part on a co-located block in the base layer of video data while assuming a residual associated with the enhancement layer block in the enhancement layer (the co-located block in the base layer being a predictor for the enhancement layer block) is equal to zero and without transmitting or receiving the residual or transform coefficients, coded block flags or a transform depth associated with the enhancement layer block. The co-located block in the base layer is located at a position in the base layer corresponding to a position of the enhancement layer block in the enhancement layer. The position on the base layer block can be adjusted according to the ratio of the base and enhancement frame resolutions. The processor may encode or decode the video data.

Abstract: 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 DC prediction value for a video unit associated with the difference video layer while refraining from using pixel information from a neighboring area of the video unit, wherein the DC prediction value is equal to zero or is offset by an offset value. The DC prediction value is a prediction value used in intra prediction based at least on an average of neighboring video units of the video unit. The processor further determines a value of the video unit based at least in part on the DC prediction value.
