PARALLEL DERIVED DISPARITY VECTOR FOR 3D VIDEO CODING WITH NEIGHBOR-BASED DISPARITY VECTOR DERIVATION

摘要

For each respective coding unit (CU) of a slice of a picture of the video data, a video coder may set, in response to determining that the respective CU is the first CU of a coding tree block (CTB) row of the picture or the respective CU is the first CU of the slice, a derived disparity vector (DDV) to an initial value. Furthermore, the video coder may perform a neighbor-based disparity vector derivation (NBDV) process that attempts to determine a disparity vector for the respective CU. When performing the NBDV process does not identify an available disparity vector for the respective CU, the video coder may determine that the disparity vector for the respective CU is equal to the DDV.

for each respective coding unit (CU) of a slice of a picture of the video data:
in response to determining that the respective CU is the first CU of a coding tree block (CTB) row of the picture or the respective CU is the first CU of the slice, setting a derived disparity vector (DDV) to an initial value;performing a neighbor-based disparity vector derivation (NBDV) process that attempts to determine an available disparity vector for the respective CU;when performing the NBDV process does not determine an available disparity vector for the respective CU, determining that the disparity vector for the respective CU is equal to the DDV; andreconstructing, based in part on the disparity vector for the respective CU, a coding block for the respective CU.
