On Signaling of TU Luma Coded Flag for CU with ACT
Authors: Lien-Fei Chen Tencent Xinwei Li Tencent Shan Liu Tencent
Abstract
It is reported that there is a mismatch on the condition of tu_y_coded_flag signaling between VVC draft JVET-R2001-v10 and VTM-9. In this contribution, it is proposed to either align VTM to draft, or to align draft to VTM.
Meeting Notes
JVET-S0231 On Signalling of TU Luma Coded Flag for CU with ACT [L.-F. Chen, X. Li, S. Liu (Tencent)]

This is identical to JVET-S0233 aspect 1. However, also the configuration is tested where the software would be aligned with text, i.e. sending the CBF when ACT is enabled. It is reported that this results in a loss of 0.1%.
