摘要： A method of video coding using block partitioning process including a binary tree partitioning process is disclosed. The block partitioning process is applied to a block of video data to partition the block into final sub-blocks. Coding process comprising prediction process, transform process or both for the block will be applied at the final sub-blocks level. The binary tree partitioning process can be applied to a given block recursively to generate binary tree leaf nodes until a termination condition is met. In another embodiment, the quadtree partitioning process is applied to a block first. The quadtree leaf nodes are further partitioned using the binary tree partitioning process. The quadtree partitioning process can be applied to a given block recursively to generate quadtree leaf nodes until a termination condition is met.

摘要： A derived disparity vector is determined based on spatial neighboring blocks and temporal neighboring blocks of the current block. The temporal neighboring blocks are searched according to a temporal search order and the temporal search order is the same for all dependent views. Any temporal neighboring block from a CTU below the current CTU row may be omitted in the temporal search order. The derived DV can also be used for predicting a DV of a DCP (disparity-compensated prediction) block for the current block in the AMVP mode, the Skip mode or the Merge mode. The temporal neighboring blocks may correspond to a temporal CT block and a temporal BR block. In one embodiment, the temporal search order checks the temporal BR block first and the temporal CT block next.

摘要： A method and apparatus for deriving inter-view candidate for a block in a picture for three-dimensional video coding are disclosed. Embodiments of the present invention derive the inter-view candidate from an inter-view collocated block in an inter-view picture corresponding to the current block of the current picture, wherein the inter-view picture is an inter-view reference picture and wherein the inter-view reference picture is in a reference picture list of the current block. The derived inter-view candidate is then used for encoding or decoding of the current motion vector or disparity vector of the current block. One aspect of the invention addresses re-use of the motion information of the inter-view collocated block. Another aspect of the invention addresses constrains on the inter-view picture that can be used to derive the inter-view candidate.
