Abstract
Intra Block Copy (IBC) mode in a screen content coding (SCC) extension in High Efficiency Video Coding (HEVC) provides high coding gain by performing motion estimation (ME) and motion compensation (MC) to find the repetitive patterns within the same frame. Merge mode and Advanced Motion Vector Prediction (AMVP), which are originally used for inter mode, are also applied to the IBC mode. However, there are redundant coding bits when they are applied to IBC. Therefore, we propose decoder-side merge mode and AMVP for IBC in SCC so as to remove the redundancy. Experimental shows that the proposed method can achieve up to 0.25% Bjontegaard delta bitrate (BD-rate) reduction compared to the conventional SCC with negligible impact to encoding and decoding complexity.
