1. A method of decoding video data, the method comprising:
receiving a video parameter set including syntax elements;
parsing a first syntax element from the video parameter set specifying whether each output layer set specified by the video parameter set contains only one layer or at least one output layer set specified by the video parameter set contains more than one layer; and
conditionally parsing, only in a case that the first syntax element specifies that the at least one output layer set specified by the video parameter set contains more than one layer, a second syntax element from the video parameter set specifying whether the video parameter set includes a general hypothetical reference decoder parameters syntax structure.
