1. A method, comprising:
obtaining a source video sequence that comprises a plurality of frames; and
performing a conversion between the source video sequence and a scalable video bitstream of visual media data according to a format rule,
wherein the scalable video bitstream comprises:
a video parameter set (VPS) that includes at least one syntax element indicating whether at least one layer in the scalable bitstream is one of a dependent layer of the scalable bitstream and an independent layer of the scalable bitstream, and
a plurality of layers, including at least one dependent layer and at least one independent layer; and
wherein the format rule specifies that:
a picture in the dependent layer is to be decoded by parsing and interpreting an inter-layer reference picture (ILRP) list; and
a picture in an independent layer and another picture in the dependent layer are each to be decoded without parsing and interpreting the ILRP list.
