1. A computer-implemented decoding method, comprising:
determining a value of a pps_chroma_tool_offsets_present_flag signaled in a picture parameter set (PPS) associated with a video sequence; and
in response to the value of the pps_chroma_tool_offsets_present_flag being equal to 1, decoding one or more picture level chroma de-blocking parameters in a bitstream associated with the video sequence,
wherein when the value of the pps_chroma_tool_offsets_present_flag is equal to 0, no picture level chroma de-blocking parameter is signaled in the bitstream, and
wherein the one or more picture level chroma de-blocking parameters comprise at least one of a beta offset or a tc offset.
