Dear W3C Colleagues: This is a request for a joint meeting from the Accessible Platform Architectures (APA) Working Group. We note that both our WGs are meeting Thursday and Friday at TPAC, and we would appreciate an hour of your time on several accessibility topics of joint interest. Most critically we in APA are concerned that implementations of WebRTC support cann support the Real Time Text (RTT) protocol being required of telecommunications providers in the U.S. by the Federal Communications Commission (FCC). There are several wrinkles to this requirement, several of which are addressed in the forwarded message below. We want you to be fully aware of the requirements as they currently exist, and their impact on persons who are deaf or hearing impaired (primarily). Beyond this most immediate concern we have been developing several accessibility related use cases we would hope you can address in future revisions of WebRTC, if not already supported. An early draft of our document is available here: https://www.w3.org/WAI/APA/wiki/Accessible_RTC_Use_Cases Please advise if and when we might meet during Thursday or Friday of TPAC. Thanking you in advance for your consideration, Janina Sajka, Chair Accessible Platform Architectures (APA) WG http://www.w3.org/WAI/APA/ Joshue O Connor writes: > Hi Dom, > > [with Janina and Jason - leads on APA/RQTF respectively, and Judy] > > It was good to talk earlier and hope here to unpick the question about RTT > interoperability and how WebRTC will need to support that.
