Abstract
This paper proposes the CU-based approach for merge candidate list construction for providing reduced complexity and improved parallelism compared to the PU-based one. In the proposed method, a CU can have only one merge candidate list. So, Only one common merge candidate list is used for all PUs in a CU regardless of the PU partition type. The simulation results of proposed method showed that the encoder computational complexity was decreased by 3% to 6% and the decoder computational complexity was negligible change with the penalty of roughly 0.2% - 0.5% coding loss. The proposed method has several advantages: it provides simpler design, reduced complexity, and improved parallelism.
