1. A method for decoding a picture from a bitstream, the method comprising:
decoding a first syntax element indicating a bit rate value and a second syntax element indicating a bit rate scale;
determining a bitrate for the bitstream by: (First Syntax Element+1)*2(6+Second Syntax Element);
decoding a subpicture level information (SLI) supplemental enhancement information (SEI) message indicating a fraction of a reference level corresponding to a subpicture of the picture; and
determining a bit rate of a subpicture bitstream based on multiplying the fraction with the bitrate for the bitstream, and a right shift.
