Abstract: An apparatus configured to code (e.g., encode or decode) video information includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a base layer and an enhancement layer, the enhancement layer comprising an enhancement layer (EL) block and the base layer comprising a base layer (BL) block that is co-located with the enhancement layer block. The processor is configured to determine predicted pixel information of the EL block by applying a prediction function to pixel information of the BL block, and to determine the EL block using the predicted pixel information. The processor may encode or decode the video information.

Abstract: An apparatus configured to code (e.g., encode or decode) video information includes a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a base layer and an enhancement layer. The processor is configured to up-sample a base layer reference block by using an up-sampling filter when the base and enhancement layers have different resolutions; perform motion compensation interpolation by filtering the up-sampled base layer reference block; determine base layer residual information based on the filtered up-sampled base layer reference block; determine weighted base layer residual information by applying a weighting factor to the base layer residual information; and determine an enhancement layer block based on the weighted base layer residual information. The processor may encode or decode the video information.

Abstract: An apparatus for coding video information according to certain aspects includes a memory and a processor. The memory unit is configured to store video information. The processor is configured to: obtain reference layer video information; upsample the reference layer video information in a first dimension to generate an intermediate output; constrain the intermediate output to a predetermined bit depth; and upsample the constrained intermediate output in a second dimension, wherein the second dimension is orthogonal to the first dimension.

Abstract: An apparatus configured to code video information comprises a memory unit and a processor in communication with the memory unit. The memory unit is configured to store video information associated with a reference layer (RL) and an enhancement layer (EL). The EL comprises an EL video unit and the RL comprises an RL video unit corresponding to the EL video unit. The processor is configured to perform upsampling and bit-depth conversion on pixel information of the RL video unit in a single combined process to determine predicted pixel information of the EL video unit, and determine the EL video unit using the predicted pixel information.
