Dear colleagues...
I would like to remember everybody interested or already being involved that
ITU/MPEG plan to define and issue some 3D audio standard (better: 3D audio
standard framework) during this year. The 3D audio codec is meant to be part
of the (wider) MPEG-H standard.
Will the working group be creating a preference for a royalty free
format— or will is be the normal RAND terms?
Excessive patent encumbrances appears to be one of the things which
originally blocked the deployment of B-format— and I don't see the
situation as being any different today. Getting people deploy the
hardware for good surround is enough of a barrier without the added
cost of per-unit pricing and the resulting incompatibilities created
by a failure to converge on a single standard.
I strongly encourage anyone here looking to contribute to such a
standards effort to decline to participate unless some effort is made
to produce a result which is royalty free.

The MPEG works always on RAND terms. Think of AAC, MP3, evrything ...

This is a typical FUD approach presentend by the competition.
If I have anything to say about, I'd say that any Ambisonis based
approach would be "patent-light", iof not patent-free.
This is a non-issue, I would say.
But it would be nice to know that Orange and FT don't want to include
too much own IP into the new standard... :-)
Best,

P.S.: 1st order Ambisonics should be patent-free, nowadays.
Higher orders can't be "overpatented", because the theory behind is
quite old. Certainly more than 20 years back...
P.S. 2: And I for my part didn't patent "Ambisonics of order >=2 + front
channels"... Promised! :-D
