Liaisons referred by this one LS on call for comments on an IETF WG on Internet Video Codec (netvc) [to IETF IESG]
Body
Dear ITU-T SG 16,

We are writing in response to the liaison statement received from ITU-T SG 16
requesting clarification about the goals the proposed Internet Video Codec
(NETVC) working group. The NETVC charter uses the word “competitive” in the
sense of being “comparable" and "commercially interesting." That is, the goal
of the working group is to produce a video codec that will need to have
comparable quality and efficiency as well as have IPR licensing terms make it
that commercially interesting to deploy widely at the time when the NETVC work
is finalized.

As the liaison statement notes, there are many concurrent ongoing efforts to
develop video codecs, and the NETVC work would merely be one additional such
effort. We do not view the proposed NETVC work as harmful for
interoperability, but rather as helpful, considering the fact that at present
the licensing environment creates barriers to full interoperability in many
cases. One key distinction of the NETVC work is a differentiation between
'licensing terms that would enable broad use,' which is a subjective
distinction, and 'royalty-free licensing terms,' which is a factual one. The
combination of this goal with the goal of achieving quality on par with
modern, state-of-the-art codecs is what makes NETVC distinctive.

Regards,
Alissa Cooper, IETF RAI area director 
on behalf of the IESG
