Betreff: 48-Hour Call for Consensus (CfC): TV Remote Control API Comments


This is a Call for Consensus (CfC) to the Accessible Platform Architectures
(APA) Working Group on our review of the TV Remote Control API specification
as detailed below.

I have endeavored to incorporate such API related comments as we've recieved
on an earlier draft comment beginning at:


In addition this review reflects our discussion on this topic and this
specification at our 8 March regular teleconference minuted at:


<Begin Revised Draft Comment>

The Accessible Platform Architectures (APA) Working Group makes the
following comments on the draft TV Control API specification at:


We appreciate that an API for TV remote control could be utilized for
enabling accessible alternative Web applications to provide radio and TV
services to users with disabilities who may find it difficult or impossible
to operate any user interface supplied with a particular browser or hardware
device. This is an inherent accessibility strength for any API that provides
for sufficient feature support. Regretably, we believe the current TV Remote
Control API as currently defined lacks required accessibility feature

*	alternative media support

We would draw your attention to the multiple alternative media formats that
are used by persons with disabilities as set forth in our W3C Note
publication: "Media Accessibility User Requirements (MAUR)" available


Please note that this document was developed in order to inform the
development of the HTML 5.0 specification itself. As a result of this note,
HTML provides sufficient feature support to support accessibility in HTML's
video and audio elements.

Our reading of the Tv Control API draft finds no way for users to learn of
the presence of any MAUR identified alternative media with any particular TV
content, nor any means to request display of alternative content. This is a
fundamental accessibility requirement on TV Controls and we believe it must
be factored into this specification.

*	Alternative Media on Second Screen Devices

APA's predecessor Working Group, Protocols and Formats WG also provided use
cases and requirements to the Second Screen Working Group on how alternative
media might be directed to second screen devices. We believe support for
directing alternative video, audio, and/or text to secondary devices, as
described in the MAUR,  is also a fundamental accessibility requirement on
TV Controls and should be supported in this API.

*	Legal Requirements

The Federal Communications Commission (FCC) in the U.S. has explicit legally
mandated regulations setting forth some strict requirements on how certain
alternative media are to be exposed to consumers. These regulations also
require accessible program guides.

We believe that developers should be flagged most especially on the
requirement that captioning must be enableable by top level controls. These
FCC requirements implement provisions of a U.S. law known as the
"Twenty-First Century Communications and Video Accessibility Act" as
explained by the FCC at:


The FCC's regulations pertinent to this specification were published in
December 2016 in the document: "Accessibility Requirements for Television
and Set-Top Box Controls, Menus, and Program Guides"
available at:

MS-Word: https://apps.fcc.gov/edocs_public/attachmatch/DA-16-1416A1.docx

Also relevant is the document "Display of Captioning on Equipment Used to
View Video Programming" available at:


Additionally, we would request that your API reference the MAUR in your
appendices in order to assist developers in meeting both their moral and
legal requirements in support of accessibility.

<End Draft Comment>


This CfC is now open for objection, comment, as well as statements of
support via email. Silence will be interpreted as support, though messages
of support are certainly welcome.

If you object to this proposed action, or have comments concerning this
proposal, please respond by replying on list to this message no later than
23:59 (Midnight) Boston Time, Tuesday 21 March.
