Dear IG members,

As we shared our common interest of single solution necessity of adaptive streaming on the browser last Berlin. We sent liaison letter to 3GPP right after Berlin. We will send same context to MPEG DASH scheduled to next week.
I drafted from 3GPP letter and added reply to MPEG DASH intention. The tone/content of letter is intentionally adjusted mild for initiating discussion and get initial feedback.

The recipient of this letter will be MPEG convener Leonardo because liaison letter is sent from him. CCed to Iraj DASH chair.
The sender of this letter will be W3C Web and TV IG chairs on behave of W3C Web and TV IG members. Even though the recipient of the letter was W3C.

Please feel free to comment on the draft by this weekend. Sorry for the hurried update.

Best regards,
HJ

Dear Mr. Convener and DASH experts,

The W3C has recently launched a Web and TV Interest Group, set to identify requirements and potential solutions to ensure that the Web will function well with TV.

During the second W3C Web and TV workshop, held in Berlin on 8-9 February 2011, it came to our attention that many participants of the workshop are interested in getting single solution of adaptive streaming on the browser. One of the potential possibilities is DASH. As a result, Web and TV Interest Group(IG) co-chairs would like to convey this interest from workshop participants and IG members to MPEG DASH experts, and to inquire about the licensing status of DASH. W3C has a strict royalty-free patent policy on the technologies that get adopted as core Web technologies.

We would very much appreciate if you could inform us of the current status of the specification of DASH and the possibility to work together on a royalty free profile of the specification for potential integration of DASH as adaptive streaming mechanism for audio and video in HTML.

As we see MPEG DASH is general enabler architectural framework for a starting point. Adaptive streaming for Web and TV specific discussion (for example, profiling from DASH, when DASH is chosen as baseline) would better be placed in the special working group from Web and TV activity.

MPEG DASH experts willing to discuss the topic with participants of the Web and TV Interest Group may use the public public-web-and-tv@w3.org mailing-list, whose archives are publicly available at:
  http://lists.w3.org/Archives/Public/public-web-and-tv/

Companies and individuals willing to know more about W3C and W3C process may get in touch with Francois Daoust <fd@w3.org> and Kazuyuki Ashimura <kaz@w3.org>, W3C staff contacts for the Web and TV Interest Group.

Best regards,

Yosuke, Giuseppe, Mashahito, HJ (chairs of W3C Web and TV IG)
On behalf of the W3C Web and TV IG members.
