Abstract
Systems and techniques are described herein for processing video data. For example, a process can include obtaining a video bitstream, the video bitstream including adaptive loop filter (ALF) data. The process can further include determining a value of an ALF chroma filter signal flag from the ALF data, the value of the ALF chroma filter signal flag indicating whether chroma ALF filter data is signaled in the video bitstream. The process can further include processing at least a portion of a slice of video data based on the value of the ALF chroma filter signal flag.
