IBC-Mirror Mode for Screen Content Coding for the Next Generation Video Coding Standards
This paper proposes an IBC-Mirror mode for Screen Content Coding (SCC) for the next generation video coding standards, including Versatile Video Coding (VVC) and Audio Video Standard-3 in China (AVS3). It is the first time to take mirror characteristic into consideration for SCC in VVC/AVS3. Based on the translational motion model of Intra Block Copy (IBC) mode, the function of "horizontal and vertical flipping" is further added to reduce prediction error and improve coding efficiency. The proposed IBC-Mirror mode is implemented on the latest reference software, including VTM5.0 (VVC) and HPM-5.0 (AVS3). The simulations show that the proposed mode can achieve up to 1~2% (VVC) and 4~7% (AVS3) BD-rate saving for SCC test sequences. Drafts about the mode have been submitted to AVS meeting and investigated in SCC Core Experiments (CE).
