Transform Coefficient Coding for Screen Content in Versatile Video Coding (VVC) [PDF]
ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019 A transform coefficient coding scheme is proposed for 4 × 4 blocks in Versatile Video Coding (VVC), targeting screen content applications. The proposed algorithm, called Unary Bitplane Coding (UBC), uses unary codes of the coefficient amplitudes and represents each block by their bitplanes.

An efficient geometric partitioning mode by adaptive blending method for screen content coding
Electronics Letters, Volume 59, Issue 19, October 2023., 2023 Three geometric partitioning mode (GPM) matrices are proposed for screen content coding in addition to the original GPM matrix of Versatile Video Coding. Furthermore, the efficient GPM is proposed that implicitly determines one of the four GPM matrices depending on the coding unit characteristics.

IET Image Processing, Volume 17, Issue 2, Page 597-612, 7 February 2023., 2023 Abstract In the newest generation of video coding standard, Versatile Video Coding (VVC), a new technique called Quad Tree with nested Multi‐type Tree (QTMT) structure is introduced. QTMT significantly improves the coding efficiency, but the improvement in compression performance comes at the cost of drastically increased complexity.
