One example method of video processing includes performing a conversion between a video including one or more pictures and a bitstream of the video, wherein the bitstream conforms to a format rule, wherein the format rule conditionally allows coding of a picture in one layer using reference pictures from other layers based on a first syntax element indicating whether the reference pictures from the other layers are present in the bitstream, and wherein the first syntax element is conditionally signaled in the bitstream based on a second syntax element that indicates whether an identifier of a parameter set associated with the picture is not equal to zero."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signalling of the presence of inter-layer reference pictures","description":"Methods, devices and systems for video coding and encoding, which include constraints, restrictions and signaling for subpictures, slices, and tiles, are described.
