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:


<Begin 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
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 support.

*	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


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 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 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
requirements on how alternative media are to be exposed to consumers.
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:


<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 28 February.
