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:
Systems, devices and methods are described including at an enhancement layer (EL) video encoder determining an intra mode for a current block of an EL frame based, at least in part, on one or more first intra mode candidates obtained from at least one of a lower level EL frame, or a base layer (BL) frame.
Abstract:
A three-dimensional (3D) video codec encodes multiple views of a 3D video, each including texture and depth components. The encoders of the codec encode video blocks of their respective views based on a set of prediction parameters, such as quad-tree split flags, prediction modes, partition sizes, motion fields, inter directions, reference indices, luma intra modes, and chroma intra modes. The prediction parameters may be inherited across different views and different ones of the texture and depth components.
Abstract:
Systems, apparatus and methods are described including determining a prediction residual for a channel of video data; and determining, using the first channel's prediction residual, a prediction residual for a second channel of the video data. Further, a prediction residual for a third channel of the video data may be determined using the second channel's prediction residual.
Abstract:
Described herein are techniques related to re-use of filter parameters, and particularly Sample Adaptive Offset (SAO) parameters, of a lower-layer bitstream or a coded enhancement layer bitstream for coding enhancement layer bitstream in a scalable video encoding.

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.
