Abstract

An output layer set may describe a video bitstream, or video sequence, which is extractable from a multi-layered video bitstream. Concepts related to output layer sets are described, including a concept for a random-accessible sub-bitstream indication, a concept for handling reference picture alignment, a concept for a bitstream-based OLS determination, a concept for sequence start access units of an extracted video bitstream, a concept for handling temporal sublayers in the extraction process of an output layer set, a concept for handling temporal sublayers in video parameter signaling and a concept for output layer selection in region of interest applications.
