    Abstract: A device may be configured to signal output layer set information according to one or more of the techniques described herein. The device comprising one or more processors configured to: receiving a video parameter set including syntax elements; parsing first syntax element from the video parameter set specifying whether at least one output layer set specified by the video parameter set contains more than one layer; and parsing second syntax element specifying whether the video parameter contains sequence-level hypothetical reference decoder parameters in a case that the first syntax element specifies that at least one output layer set specified by the video parameter set contains more than one layer.

    Abstract: This disclosure relates to video coding and more particularly to techniques for signaling temporal sublayer information for coded video. According to an aspect of an invention, a flag indicating whether a syntax element specifying a maximum number of temporal sublayers that are present in each coded layer video sequence referring to a sequence parameter set is present in the sequence parameter set is signaled; and the syntax element specifying a maximum number of temporal sublayers is conditionally signaled based on the value of the flag.

    Abstract: A method of decoding video data includes: 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; and 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 threshold value, wherein the second syntax element specifies whether decoded picture buffer output time offsets are present for temporal sublayer representations.

    Abstract: A method of decoding video data includes: receiving a video parameter set; parsing a first syntax element in the video parameter set, wherein the first syntax element plus one specifies a maximum allowed number of layers in each coded video sequence referring to the video parameter set; and parsing a second syntax element in the video parameter set, in a case that a value of the first syntax element is greater than a threshold value, wherein the second syntax element plus one specifies a number of profile tier level syntax structure in the video parameter set.
