1. A method implemented by a video decoder, comprising:
receiving a bitstream comprising a coded picture and a supplemental enhancement information (SEI) message, wherein the SEI message includes coded picture buffer (CPB) parameters corresponding to decoding unit (DU)-based hypothetical reference decoder (HRD) operations on sublayers, wherein each of the sublayers comprises a temporal scalable layer including video coding layer (VCL) network abstraction layer (NAL) units with a particular value of a temporal identifier (TemporalId) and associated non-VCL NAL units; and
decoding the coded picture from the bitstream to obtain a decoded picture.
