    Abstract: Techniques for inter-layer residual prediction are described. In one embodiment, for example, an apparatus may comprise an encoding component to determine whether a predicted motion for an enhancement layer block is consistent with a predicted motion for a collocated lower-layer block, determine whether to apply inter-layer residual prediction to the enhancement layer block based on whether the predicted motion for the enhancement layer block is consistent with the predicted motion for the collocated lower-layer block, and in response to a determination that inter-layer residual prediction is to be applied to the enhancement layer block, generate a predicted residual for the enhancement layer block based on a residual for the collocated lower-layer block and generate a second-order residual for the enhancement layer block by comparing a calculated residual to the predicted residual. Other embodiments are described and claimed.

    Abstract: Techniques to identify one or more candidate reference blocks used to generate a prediction block to encode a current coding block. The candidate reference blocks can be in the same layer as the current coding block or a different layer. In addition, the candidate reference blocks do not have to be co-located with the current coding block. Motion vectors and shift vectors can be used to identify the one or more candidate reference blocks. In addition, uniform and non-uniform weighting can be applied to the one or more candidate reference blocks to generate the prediction block. Accordingly, an encoder can determine and identify reference blocks to a decoder that can provide desirable rate-distortion cost.
