1. A method of signaling a temporal sublayer information for video data, the method comprising:
signaling a flag indicating whether a first syntax element related to a maximum number of temporal sublayers that are present in a coded layer video sequence is present, wherein the first syntax element is a 3-bit unsigned integer, and the flag and the first syntax element precede a second syntax element that is required to be equal to zero for a conforming bitstream; and
conditionally signaling the first syntax element based on a value of the flag.
