1. A method of decoding video data, the method comprising:
determining a number of output layer sets with more than one layer;
determining a number of decoded picture buffer parameters syntax structures in a video parameter set;
in a case that the number of the decoded picture buffer parameters syntax structures is not equal to the number of the output layer sets with more than one layer, decoding a syntax element specifying an index of the decoded picture buffer parameters syntax structures; and
in a case that the syntax element is not present, inferring a value of the syntax element.
