Abstract
This contribution reports the results of CE3-2.4 in which BDPCM (luma and chroma) is enabled for lossless coding. In aspect #1, a high-level flag (e.g. SPS/PPS) is used to select the residual coding method between regular residual coding (RRC) and transform skip residual coding (TSRC). For example, if the appropriate flag value is 1 then RRC is always used. In the second aspect, a slice-level flag with an encoder change is used from CE3-1.3. This slice-level flag switches between TSRC and RRC based on the encoder decision for a frame. In both aspects luma and chroma BDPCM are enabled for lossless coding.
