ADVANCED MERGE/SKIP MODE AND ADVANCED MOTION VECTOR PREDICTION (AMVP) MODE FOR 3D VIDEO

摘要

Techniques are described where if an inter-view predicted motion vector candidate (IPMVC) and an inter-view disparity motion vector candidate (IDMVC) are derived based on a shifted disparity vector, where the amount by which the disparity vector is shifted for the IPMVC and IDMVC is different. The techniques also prioritize the inclusion of the IPMVC over the IDMVC in a candidate list, and prune the IPMVC and the IDMVC if there is a duplicated IPMVC or IDMVC in the candidate list.

1. A method of coding video data, the method comprising:
determining whether a current block is inter-predicted in merge mode, skip mode, or advanced motion vector prediction (AMVP) mode; if the current block is inter-predicted in AMVP mode, determining whether to derive an inter-view disparity motion vector candidate (IDMVC) or an inter-view predicted motion vector candidate (IPMVC) based on at least one reference picture index; if the current block is inter-predicted in merge mode or skip mode, determining availability of the IPMVC, wherein the IPMVC comprises motion information for a reference block in a reference view referred to by a disparity vector, for the current block, shifted by a first offset value, and wherein the IDMVC comprises the disparity vector, for the current block, shifted by a second, different offset value; determining whether the IPMVC or the IDMVC is to be included in a candidate list; and inter-prediction coding the current block in a current picture in a current view, different form the reference view, based on the candidate list.
