Systems and methods for signaling buffering period information in video coding

A method of decoding video data, the method comprising:

• receiving a buffering period message;
• parsing 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;
• parsing a second syntax element in the buffering period message, in a case that a value of the first syntax element is greater than a first threshold value, wherein the second syntax element specifies whether decoded picture buffer output time offsets are present for temporal sublayer representations;
• and
• parsing a third syntax element in the buffering period message, in a case that a value of the first syntax element is greater than a second threshold value, wherein the third syntax element specifies whether initial coded picture buffer removal delay related syntax elements are present for temporal sublayer representations in a range from 0 to M-1 or initial coded picture buffer removal delay related syntax elements are present for (M-1)-th temporal sublayer representation.
