    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: A video encoder is configured to encode a binary sting indicating a position of a last significant coefficient within a video block. A video decoder is configured to decode the encoded binary string. The string may be coded using context adaptive binary arithmetic coding (CABAC). Binary indices of the binary string may be assigned a context. The context may be determined according to a mapping function. A context may be a assigned to one or more binary indices where each index is associated with a different block size. The last binary index of a 16×16 video block may share a context with the last binary index of a 32×32 video block.
