Device and method for scalable and multiview/3D coding of video information

摘要

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.

1. An apparatus configured to code video information, the apparatus comprising:
a memory configured to store video information associated with a base layer and an enhancement layer; and a processor in communication with the memory, the processor configured to:
determine a base layer reference block using an enhancement layer motion vector;up-sample the 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; andperform one of: (i) in response to determining that a luma-only mode is enabled, determine only a luma component of an enhancement layer block based on the weighted base layer residual information and determine chroma components of the enhancement layer block by using intra-layer temporal prediction, or (ii) in response to determining that a chroma-only mode is enabled, determine only the chroma components of the enhancement layer block based on the weighted base layer residual information and determine the luma component of the enhancement layer block by using intra-layer temporal prediction,wherein the up-sampling filter has 6 or fewer taps.
