older persons and persons with disabilities) provides the
framework for accessibility
ITU-T FSTP-TACL (Telecommunications Accessibility
Checklist) provides the check-list for Accessibility features.
ITU-T Y.1901 (IPTV Requirements) specifies detailed
requirements on accessibility features and universal design
ITU-T H.750 (Metadata for IPTV) also has “Public Interest
metadata” which includes accessibility related features.
ITU-T H.721 (IPTV Terminal Devices) recommends “Public
services” such as closed-captioning, subtitles, audio

interactivity, based on web-technologies,
such as XML, HTML, and Scripts. - H.761
(Ginga-NCL) and/or H.762 (LIME).
 Secure IP (bi-directional) connection of
IPTV makes important and valuable
applications and services accessible to
people with difficulties
 Accessibility-related areas such as ehealth, e-government, e-commerce,

Points to be worked on
 Too much diversity will lead to confusion
 Standard guidelines on Accessibility for
IPTV devices may be necessary – especially
from User Interface point of view
 Consorted efforts among SDOs to provide
end-to-end accessibility for all

Standard for Accessible Remote Control?
 Remotes are
important UI device
for IPTV
 Remotes can be a
differentiating factor
of a vendor and
service provider
 But can be very
problematic if they
are different
 Standardized for
remotes for IPTV will
be necessary

Collaboration with other SDOs
 ITU-T IPTV GSI has been working with
following SDOs
 IEC TC 100 on “Integrated TV” -> Remotes
may be another
 W3C on Web-technologies -> Now Weband-TV Interest Group
 MPEG (ISO/IEC) on Codecs and Advanced
IPTV
 Accessibility an important point for all of us

divide
Managed IPTV is important for
accessibility
ITU-T IPTV Standards incorporated
Accessibility guidelines
