Abstract

An electronic device for decoding a picture from a data stream is disclosed, the electronic device includes a processor. The processor configured to decode a first syntax element indicating a bit rate value and a second syntax element indicating a bit rate scale. The processor is also configured to determine a fraction of a reference level corresponding to a subpicture of the picture, using a subpicture level information (SLI) supplemental enhancement information (SEI) message. The processor is further configured to determine a bit rate of the subpicture based on the fraction, the first syntax element, and the second syntax element.
