AHG17: On max QT/BT/TT size signaling
Authors: Y. Du Tencent Xinwei Li Tencent Xin Zhao Tencent Byung-Yoon Choi Tencent S. Wenger Tencent Shan Liu Tencent
Abstract
In this contribution, it is proposed to signal max QT/BT/TT sizes relative to CTU size instead of min QT size in SPS and slice header to be more bit-efficient. It is reported that -0.01% for RA and -0.04% for LDB coding gain can be obtained using the proposed method. It is reported that -2.46% for AI, -1.10% for RA, and -2.07% for LDB bits saving can be obtained in SPS, -5.14% for RA and -5.65% for LDB bits saving can be obtained in slice header.
