Abstract

A device may be configured to decode video data based on information included in a photosensitive content information message. In one example, a photosensitive content information message includes syntax elements indicating information regarding photosensitive content characteristics. In one example, a syntax element specifies whether photosensitive content in pictures in a persistence scope of the photosensitive content information message exceed photosensitivity content guidelines specified by a standard. In one example, a syntax element specifies whether photosensitive content in pictures in the persistence scope of the photosensitive content information message exceed a particular photosensitivity content guideline specified by the standard.

Claims (17)

1 . A method of decoding video data, the method comprising:

receiving a photosensitive content information message;

parsing a first syntax element in the photosensitive content information message, wherein the first syntax element specifies whether photosensitive content in pictures in a persistence scope of the photosensitive content information message exceed photosensitivity content guidelines specified by a first standard;

parsing a second syntax element in the photosensitive content information message, wherein the second syntax element specifies whether photosensitive content in pictures in the persistence scope of the photosensitive content information message exceed a first photosensitivity content guideline specified by the first standard; and

parsing a third syntax element in the photosensitive content information message, wherein the third syntax element specifies whether photosensitive content in pictures in the persistence scope of the photosensitive content information message exceed a second photosensitivity content guideline specified by the first standard.

2 . A device comprising one or more processors configured to:

receive a photosensitive content information message;

parse a first syntax element in the photosensitive content information message, wherein the first syntax element specifies whether photosensitive content in pictures in a persistence scope of the photosensitive content information message exceed photosensitivity content guidelines specified by a first standard;

parse a second syntax element in the photosensitive content information message, wherein the second syntax element specifies whether photosensitive content in pictures in the persistence scope of the photosensitive content information message exceed a first photosensitivity content guideline specified by the first standard; and

parse a third syntax element in the photosensitive content information message, wherein the third syntax element specifies whether photosensitive content in pictures in the persistence scope of the photosensitive content information message exceed a second photosensitivity content guideline specified by the first standard.

3 . The device of claim 2 , wherein the device includes a video decoder.

4 . A device comprising one or more processors configured to:

signal a photosensitive content information message, wherein the photosensitive content information message includes:

a first syntax element, wherein the first syntax element specifies whether photosensitive content in pictures in a persistence scope of the photosensitive content information message exceed photosensitivity content guidelines specified by a first standard,

a second syntax element, wherein the second syntax element specifies whether photosensitive content in pictures in the persistence scope of the photosensitive content information message exceed a first photosensitivity content guideline specified by the first standard, and

a third syntax element, wherein the third syntax element specifies whether photosensitive content in pictures in the persistence scope of the photosensitive content information message exceed a second photosensitivity content guideline specified by the first standard.

5 . The device of claim 4 , wherein the device includes a video encoder.
