Overview of the Screen Content Support in VVC: Applications, Coding Tools, and Performance

In an increasingly connected world, consumer video experiences have diversified away from traditional broadcast into new applications with increased use of non-camera-captured content such as computer screen desktop recordings or animations created by rendering, collectively referred to content. There has also been graphics and character that is rendered mixed overlaid together camera-generated The emerging Versatile Video Coding (VVC) standard, in its first version, addresses this market change the specification low-level coding tools suitable for This contrast predecessor, High Efficiency (HEVC) where highly efficient support only available extension profiles version 4. paper describes five main VVC: transform skip residual (TSRC), block-based differential pulse-code modulation (BDPCM), intra block copy (IBC), adaptive color (ACT), palette mode. these VVC enables reference software implementation (VTM) achieve average bit-rate savings about 41% 61% relative HEVC test model (HM) using Main 10 profile 4:2:0 sequences. Compared HM Screen-Extended same sequences, VTM provides 19% 25% savings. comparison 4:4:4 sequences revealed 13% 27% $Y'C_{B}C_{R}$ 6% 14% notation="LaTeX">$R'G'B'$ Relative without 4 extensions, are 33% 64% 43% 66%
