Abstract
A bitstream processing technique includes obtaining a first parameter set identifier from a data unit containing bits corresponding to a coded video region, obtaining a tool flag from a first parameter set corresponding to the first parameter set identifier, determining, from the tool flag, that a tool parameter of a tool corresponding to the tool flag is present or enabled for decoding the coded video region, wherein the tool corresponds to a video coding technique, obtaining, based on the determining, a second parameter set identifier, obtaining the tool parameter from a second parameter set corresponding to the second parameter set identifier, and decoding the video region using the tool parameter.
