1. A method of decoding image data, the method comprising:
receiving a buffering period message;
decoding a first syntax element in the buffering period message, wherein the first syntax element plus one specifies a maximum number (M) of temporal sublayers for which coded picture buffer removal delay and coded picture buffer removal offset are indicated in the buffering period message, wherein the first syntax element immediately follows a second syntax element, wherein the second syntax element plus one specifies a coded picture buffer removal delay increment value;
decoding a first present flag syntax element in the buffering period message in a case that a value of the first syntax element is greater than a threshold value, wherein the first present flag syntax element specifies (a) the buffering period message contains coded picture buffer removal delay deltas or (b) no coded picture buffer removal delay deltas are present in the buffering period message; and
decoding a second present flag syntax element in the buffering period message in the case that the value of the first syntax element is greater than the threshold value,
wherein the second present flag syntax element specifies (a) initial coded picture buffer removal delay related syntax elements are present for sublayer representations in a range from 0 to M−1 or (b) initial coded picture buffer removal delay related syntax elements are present for (M−1)-th sublayer representation.
