Abstract
A device may be configured to decode video data based on information included in a text description information message. In one example, a text description information message includes a syntax element indicating a role of the text description information message. In one example, a text description information message includes a syntax element specifying a text description information string having a value which is interpreted as indicated by a role.
Claims2
A method of decoding video data, the method comprising:
- receiving a text description information message;
- parsing a first syntax element in the text description information message, wherein the first syntax element indicates a purpose of the text description information message, wherein the first syntax element having a value of 0 indicates that the purpose is Application defined, the first syntax element having a value of 1 indicates that the purpose is Copyright information, and the first syntax element having a value of 2 indicates that the purpose is AI marking information;
- and
- parsing a second syntax element in the text description information message, wherein the second syntax element specifies a text description information string whose value is interpreted as specified by the first syntax element.
1 more element
A video decoder comprising one or more processors configured to:
- receive a text description information message;
- parse a first syntax element in the text description information message, wherein the first syntax element indicates a purpose of the text description information message, wherein the first syntax element having a value of 0 indicates that the purpose is Application defined, the first syntax element having a value of 1 indicates that the purpose is Copyright information, and the first syntax element having a value of 2 indicates that the purpose is AI marking information;
- and
- parse a second syntax element in the text description information message, wherein the second syntax element specifies a text description information string whose value is interpreted as specified by the first syntax element.
