Abstract
A device may be configured to decode video data based on information included in a source picture timing information message. In one example, a source picture timing information message includes a syntax element message specifying a scale factor used in determining the source picture interval of corresponding consecutive pictures in output order. In one example, the scale factor based on a value specified by the syntax element and a variable.
Claims3
A method of decoding video data, the method comprising:
- receiving a source picture timing information message;
- parsing a first syntax element in the source picture timing information message indicating whether a second syntax element specifying a source type is present in the source picture timing information message;
- parsing a third syntax element in the source picture timing information message specifying a scale factor used in determining the source picture interval of corresponding consecutive pictures in output order;
- and
- determining the scale factor based on a value specified by the second syntax element and a variable, wherein the variable is equal to 0, in the case that the first syntax element is equal to 0.

A device comprising one or more processors configured to:
- receive a source picture timing information message;
- parse a first syntax element in the source picture timing information message indicating whether a second syntax element specifying a source type is present in the source picture timing information message;
- parse a third syntax element in the source picture timing information message specifying a scale factor used in determining the source picture interval of corresponding consecutive pictures in output order;
- and
- determine the scale factor based on a value specified by the second syntax element and a variable, wherein the variable is equal to 0, in the case that the first syntax element is equal to 0.
