Abstract
Systems and methods are described for generating and decoding a video data bit stream containing a high-level signaling lossless coding syntax element indicating that lossless coding is used. The high-level signaling syntax is one of a Video Parameter Set (VPS), Sequence Parameter Set (SPS), Picture Parameter Set (PPS), or slice segment header. The lossless coding syntax element may be used as a condition for generating one or more SPS, PPS and slice segment header syntax elements related to the quantization, transform, transform skip, transform skip rotation, and in-loop filtering processes.
