Abstract
This contribution proposes to include some non-adjacent temporal MVPs (NATMVP) in not only the merge candidate list but also the AMVP candidate list. The proposed candidate NATMVPs are derived from the blocks that are temporally collocated non-adjacently right-side and down-side to the current block. These NATMVPs are added into the merge candidate list and the AMVP candidate list after the non-adjacent spatial MVPs (NASMVP) of the same distance. It is reported that the simulation results are as follows:

This contribution proposes to include some non-adjacent temporal MVPs (NATMVP) in not only the merge candidate list but also the AMVP candidate list. The proposed candidate NATMVPs are derived from the blocks that are temporally collocated non-adjacently right-side and down-side to the current block. These NATMVPs are added into the merge candidate list and the AMVP candidate list after the non-adjacent spatial MVPs (NASMVP) of the same distance. It is reported that the simulation results are as follows:

Test 1: RA: -0.02%, -0.05%, -0.05%, 102% 104%; LB: -0.14%, -0.08%, -0.08%, 103% 106% over ECM3.1

Test 2: RA: -x.xx%, -x.xx%, -x.xx%, xx% xx%; LB: -x.xx%, -x.xx%, -x.xx%, xx% xx% over ECM3.1

Test 3: RA: -x.xx%, -x.xx%, -x.xx%, xx% xx%; LB: -x.xx%, -x.xx%, -x.xx%, xx% xx% over ECM3.1 EE2-3.6a

Results incomplete, but so far no significant gain – no action
