Claim 17:
18. One or more non-transitory computer-readable media having stored thereon encoded data in a bitstream for pictures of a video sequence, the encoded data being organized to facilitate decoding with operations comprising:
receiving a coded picture buffer removal delay (“CPBRD”) delta value for a given access unit for a current picture among the pictures of the video sequence, the current picture having a first-type supplemental enhancement information (“SEI”) message associated with the current picture;
receiving a value of a concatenation flag for the given access unit, wherein:
if the value of the concatenation flag is a first value, a CPBRD value in a second-type SEI message for the given access unit indicates an increment value specifying a nominal coded picture buffer (“CPB”) removal time of the current picture relative to a nominal CPB removal time of a first preceding picture in decoding order, the first preceding picture having a first-type SEI message associated with the first preceding picture; and
if the value of the concatenation flag is a second value, the nominal CPB removal time of the current picture is indicated, by the CPBRD delta value, as an increment value relative to a nominal CPB removal time of a second preceding picture in decoding order; and

decoding the current picture, including parsing the CPBRD delta value and the value of the concatenation flag for the given access unit from the first-type SEI message associated with the current picture.
