Abstract
This contribution reports the results of CE3-2.3 in which luma BDPCM is enabled for lossless coding. In aspect #1, a high-level flag (e.g. SPS/PPS) is used to switch the residual coding method between regular residual coding (RRC) and transform skip residual coding (TSRC). If the flag value is 1 then RRC is always used with luma BDPCM enabled. In the second aspect, a slice-level flag with an encoder change is based from CE3-1.3. This flag switches between TSRC and RRC based on the encoder decision on IBC usage.
