Claim 2:
3. A non-transitory computer readable medium storing a bitstream, wherein the bitstream comprises:
a picture parameter set (PPS) associated with a video sequence, the PPS comprising a pps_chroma_tool_offsets_present_flag indicating whether chroma de-blocking parameters are signaled in the bitstream,
wherein when a value of the pps_chroma_tool_offsets_present_flag is equal to 1, the bitstream comprises one or more picture level chroma de-blocking parameters,
wherein when the value of the pps_chroma_tool_offsets_present_flag is equal to 0, the bitstream does not comprise the one or more picture level chroma de-blocking parameters, and
wherein the one or more picture level chroma de-blocking parameters comprise at least one of a beta offset or a tc offset.
