低減ビット深度更新モードおよび低減色度サンプリング更新モードを用いるビデオコーディングおよびデコーディングのための方法および装置

摘要

Methods and apparatus are provided for video coding and decoding with reduced bit-depth update mode and reduced chroma sampling update mode. An apparatus includes an encoder for encoding at least a portion of a picture using at least one of a reduced bit-depth update mode and a reduced chroma sampling update mode that respectively reduces at least one of a bit-depth and a chroma sampling of a residue signal corresponding to the portion.
