Abstract
This disclosure relates to video coding and more particularly to techniques for signaling buffering period information for coded video. According to an aspect of an invention, a second syntax element in a buffering period syntax structure is parsed wherein the second syntax element specifies whether coded picture buffer related syntax elements are present for each temporal sublayer in a range of 0 to a value of a first syntax element or whether the coded picture buffer related syntax elements are present for the first syntax element'th temporal sublayer.
Claims4
A method of decoding video data, the method comprising:
- receiving a buffering period information message;
- parsing a first syntax element in the buffering period information message,
- wherein the first syntax element specifies a number of instances of a second syntax element in the buffering period information message;
- for each of a value of the first syntax element,
- parsing the second syntax element in the buffering period information message, wherein the second syntax element specifies a coded picture buffer removal delay delta;
- receiving a picture timing information message;
- and
- parsing a third syntax element in the picture timing information message, in a case that the value of the first syntax element is greater than one, wherein the third syntax element specifies an index of a coded picture buffer removal delta.
A device comprising one or more processors configured to:
- receive a buffering period information message;
- parse a first syntax element in the buffering period information message,
- wherein the first syntax element specifies a number of instances of a second syntax element in the buffering period information message;
- for each of a value of the first syntax element,
- parse the second syntax element in the buffering period information message, wherein the second syntax element specifies a coded picture buffer removal delay delta;
- receive a picture timing information message;
- and
- parse a third syntax element in the picture timing information message, in a case that the value of the first syntax element is greater than one, wherein the third syntax element specifies an index of a coded picture buffer removal delta.
A device comprising one or more processors configured to:
- signal a buffering period information message;
- wherein the buffering period information message includes:
- a first syntax element, wherein the first syntax element specifies a number of instances of a second syntax element in the buffering period information message, and
- for each of a value of the first syntax element,
- the second syntax element, wherein the second syntax element specifies a coded picture buffer removal delay delta;
- and
- signal a picture timing information message;
- wherein the picture timing information message includes a third syntax element, in a case that the value of the first syntax element is greater than one, wherein the third syntax element specifies an index of a coded picture buffer removal delta.
