Liaisons referred by this one Liaison Statement on URI Signing for MPEG-DASH
Body
IETF would like to inform the MPEG experts of our receipt of your liaison
letter and our careful consideration during the recent IETF meeting in Dallas,
TX on March 25th. The IETF reviewed the MPEG-DASH request and has agreed to
work towards a solution within the IETF.  With this in mind, we have agreed to
extend the use case of the URI Signing draft
(https://tools.ietf.org/html/draft-ietf-cdni-uri-signing-03) to support
segmented DASH and HTTP adaptive streaming content.  The next draft is
expected to be completed by June 2015.  The originally target completion date
for the document is August 2015.  With this scope addition, we expect this
date to be moved into 2016.  The working group will re-target dates during the
July IETF meeting.  The IETF welcomes review and comment on future revisions
of the URI Signing draft.

The IETF welcomes review, comments and feedback on future revisions to the URI
Signing drafts.  In addition, we welcome collaboration on this topic and in
the development of a solution, which meets the requirements of MPEG-DASH use
of URI Signing.  IETF would like for MPEG experts to submit more details, if
available, of DASH URI signing requirements along with DASH use cases to the
chairs of the IETF CDNI working group chairs:

Daryl Malas (d.malas@cablelabs.com)
Francois Le Faucheur (flefauch@cisco.com)

We welcome your participation at our next meeting: IETF CDNI Working Group
meeting, 19 – 24 July 2015, Prague (http://ietf.org/meeting/93/index.html)
