AHG13: Sign Data Hiding
Authors: P. Yin Dolby Sean McCarthy Dolby F. Pu Dolby T. Lu Dolby W. Husak Dolby T. Chen Dolby T. Tsukuba Sony
Abstract
This document reports the tool-on results for Sign Data Hiding (SDH), which is included in HEVC but not included in VTM or BMS. This document also breaks out the performance gains of SDH for specific test sequence classes and encoding modes.
Meeting Notes
JVET-K0310 AHG13: Sign Data Hiding [P. Yin, S. McCarthy, F. Pu, T. Lu, W. Husak, T. Chen (Dolby), T. Tsukuba (Sony)]

It was said that sign data hiding can provide 0.9% on AI and 0.7% on RA for the VTM with 3–4% encoder increase (and no decoder complexity increase). See also the AHG13 report, which indicated that the previous non-inclusion of SDH in VVC had a larger impact on coding efficiency than other removed features relative to HEVC (other having 0.4% impact or less, and in RA it was the only one with a significant impact), and had a good tradeoff of coding efficiency and complexity.

Decision: Adopt SDH into WD/VTM (can only be used when dependent quantization is disabled).
