JCTVC-J0038 Exif data SEI message [K. Ugur, J. Lainema, M. Hannuksela (Nokia)]

This contribution proposes a way to associate EXIF information for each picture of the video sequence as an SEI message. It is argued that the feature is especially useful for still pictures but could have use for video content as well.

Suggested to put EXIF either into an SEI message or associate at systems layer (e.g. file format)

Format: Payloadsize, metadata. W.r.t. definition, it is suggested to refer to EXIF standard.

Concerns:

• 
  EXIF data would overlap with some existing SEI messages
  
• 
  Better at systems layer?
  

An expert from JPEG also suggested to put this at the systems layer (file format)

Would also be undesirable to refer to another standard without having control.
Conclusion: Several concerns the idea of putting “EXIF as is” in an SEI message (video stream), but there was also support expressed that it is useful to have such link at the systems layer.
