AHG9: On signalling of chroma deblocking filter parameters for monochrome
Authors: T. Tsukuba Sony M. Ikeda Sony Y. Yagasaki Sony Teruhiko Suzuki Sony Takeshi Tsukuba
Abstract
In the latest VVC WD, parameters (beta_offset_div2, tc_offset_div2) for deblocking filter are signaled for each component in PPS, Picture Header and Slice Header. In monochrome coding, those parameters for chroma deblocking filter are still signaled and can take any value in the valid range, which are obviously redundant:
