Abstract
In this contribution, a method of reducing the local inter-dependency as well as the number of merge candidate list generation operations is proposed. The method uses 2 parameters ( and ) as 2 thresholds of coding splitting node area. (). For splitting nodes with the size of , all merge candidate list generation operations within the area can be performed in parallel. And for all blocks within a splitting area with the size of , a shared merge candidate list is used. Simulation results for multiple sets of and are presented.
Meeting Notes
JVET-M0507 CE4-related: Hybrid Merge Estimation Region [H. Wang, V. Seregin, W.-J. Chien, T. Hsieh, Y. Han, M. Karczewicz (Qualcomm)]

Notes from the BoG report review: JVET-M0507 has two aspects, where the aspect of removing the clipping for the shared merge list might also be beneficial on top of JVET-M0170. It is reported to come at no coding loss. The proponents of JVET-M0507 discussed with proponents of JVET-M0170 that the check for one of the subbocks being outside of the picture could be removed, whereas another check whether the CU center is still inside needed to be added, to make it consistent with other boundary check conditions in VVC. Proponents of JVET-M0170 were to make an update on this aspect.
