[Mp7-tech] How to generate MPEG7 streams in .mp4 files ?

[Wo Chang]

Dear James and All,
Thanks for sharing your industry needs and I have good news for you!
Within ISO/IEC SC 29 WG11 (MPEG) there is a new work going on called
Multimedia Application Format (MAF) AdHoc Group and its mandates are
to extend the MPEG-4 file format to include MPEG-7 & MPEG-21 metadata.
The near-term goal is to have MPEG-4 file format to include MPEG-7 metadata
so that it could embed the MPEG-7 equivalent metadata tags as to ID3 and EXIF 
(digital pictures) into the same MPEG-4 file container.
However, I'm not sure how people/company can get involve in the standard
process if they are outside the standard committee, but they are welcome 
to join the committee.
Best regards,

  Hello there,
  I am contacting you on behalf of a company called versatile delivery systems, we are trying to get some clarification in regard to embedding mpeg7 xml in mpeg4 files.
  Over the last year we have developed a video tagging system. We wish to be able to generate an MPEG7 stream to carry the metadata, but have been unable to find out how to do this, as the following snip from an e mail conversation with Jan devos of the 3ivx company shows:
      We are finding it very difficult to access any expertise in this area, and I have yet to actually find an example of MPEG7 embedding in .mp4 , although it is in the standard - has anyone actually achieved this ? Any more information or leads you could give us in this regard would be much appreciated...
    My understanding is that there are some items MPEG-7 does not cater for which is why Apple chose to use ID3 tags in .mp4 files with iTunes. Since Apple was the first major company to roll out .mp4 files with meta data this became the de-facto standard.
    Besides that if I recall correctly MPEG-7 data in .mp4 files is still in the process of being standardized.
  If there is any help you could give us to help us get to the bottom of this problem, your feedback would be much appreciated
  Yours sincerely
