Signaling of picture order count to timing information relations for video timing in video coding

A method of encoding video data, the method comprising:

• encoding pictures of a video sequence to generate a coded video sequence comprising the encoded pictures;
• and
• signaling timing parameters for the coded video sequence by signaling an indication of whether a picture order count (POC) value for each picture in the coded video sequence that is not a first picture in the coded video sequence according to a decoding order is proportional to an output time of the picture relative to an output time of the first picture in the coded video sequence in a video parameter set (VPS) syntax structure referenced by the coded video sequence.

A device for processing video data comprising:

• means for receiving a coded video sequence comprising encoded pictures of a video sequence;
• and
• means for receiving timing parameters for the coded video sequence that include an indication of whether a picture order count (POC) value for each picture in the coded video sequence that is not a first picture in the coded video sequence according to a decoding order is proportional to an output time of the picture relative to an output time of the first picture in the coded video sequence in a video parameter set (VPS) syntax structure referenced by the coded video sequence.

A non-transitory computer readable storage medium storing instructions that upon execution by one or more processors cause the one or more processors to:

• receive a coded video sequence comprising encoded pictures of a video sequence;
• and
• receive timing parameters for the coded video sequence that include an indication of whether a picture order count (POC) value for each picture in the coded video sequence that is not a first picture in the coded video sequence according to a decoding order is proportional to an output time of the picture relative to an output time of the first picture in the coded video sequence in a video parameter set (VPS) syntax structure referenced by the coded video sequence.
