Non-CE4: Context modeling for inter prediction mode
Authors: Junghak Nam LGE Hyeongmun Jang LGE N. Park LGE J. Lim LGE S. Kim LGE
Abstract
In VVC, inter_pred_idc syntax which specifies inter prediction mode uses five context models. Especially, the 5th context model is being shared by the 4x16, 8x8, or 16x4 bi-predicted CUs and uni-predicted CUs. This contribution proposes two alternative methods to prevent from the 5th context model being shared between bi-prediction and uni-prediction cases. From experiment results, luma BD-rate changes of method 1 is reported as -0.01% and -0.02% for RA and LDB. luma BD-rate changes of method 2 is reported as -0.02% and -0.03% for RA and LDB.
