JCTVC-J0433 AHG5: Cross check of Canon’s Merge index coding (JCTVC-J0177) by Qualcomm [I. S. Chong, M. Karczewicz (Qualcomm)] [late]
JCTVC-J0180 Zero merge candidate simplification [B. Li, H. Li (USTC), H. Yang (Huawei)]

This contribution presents a modification on the construction of the zero merge candidates for B slices. Specifically, bi-directional zero merge candidates are replaced by uni-directional zero merge candidates in B slices. It is asserted that the complexity of motion compensation can be reduced with the proposed modification, while the BD-Rate change is reported to be 0.0% under common test condition.

Comments:

In terms of implementation (hardware or software), this does not give a big deal. It touches the most simple part of the merge process.

Several experts express the opinion that there would be no good reason to change a part that has been stable for several meetings.

No action.
