ITU standards will enhance television viewing experience
World Television Day highlights role of TV in global communication
Geneva, 21 November 2014 – Today is World Television
Day. Television is recognized as a major tool in informing, channelling and
affecting public opinion. Its impact and influence on world public opinion
and decision-making cannot be denied and today Television represents a
symbol for communication and globalization in the contemporary world.
The United Nations General Assembly proclaimed 21 November as World
Television Day in 1996 in recognition of the increasing impact television
has on decision-making by bringing world attention to threats to peace and
security and its potential role in sharpening the focus on other key areas,
including economic, environmental and social issues.
“ITU is currently working on developing new standards that will
dramatically enhance the television viewer’s experience, in terms of both
visual and audio quality,” said ITU Secretary-General Hamadoun I. Touré.
“ITU is developing industry-leading standards for the next generation of
television that will be available in very high definition as well as high
performance dynamic video streaming.”
The first commercial services of Ultra High Definition Television have
already begun. In coming years, ITU systems will allow television with four
times the detail of the first UHDTV services. The work of ITU today includes
the study of techniques to produce a super wide range of contrast to the
television image, bringing it closer to the real world.
The second edition of High Efficiency Video Coding (HEVC), Recommendation
ITU-T H.265 | ISO/IEC International Standard 23008-2 approved in October
2014, includes enhanced format range extensions to improve video quality,
general multi-layer support, scalability to cope with IP network congestion,
and native 3D (multi-view) video encoding. The new codec will considerably
ease the burden on global networks where, by some estimates, video accounts
for more than half of bandwidth use. HEVC will unleash a new phase of
innovation in video production spanning the whole ICT spectrum, from mobile
devices through to Ultra-High Definition TV.
ITU standards also continue to examine ways to make television more
accessible to those with disabilities and special needs, such as providing
subtitles and audio channels describing the action in the image, as well as
future options such as the capacity of the viewer to separate foreground and
background sound, allowing the audio to be more intelligible to those with
hearing disabilities. Audio-visual media pervades nearly every aspect of
modern life and ITU’s work to improve the accessibility of TV to persons
with special needs is crucial in building an inclusive Information Society.
“ITU is striving for good and efficient future use of the radio-frequency
spectrum to carry television broadcasting,” said Christoph Dosch, Chairman
of ITU-R Study Group 6, which deals with broadcasting issues. “In order to
continue to develop new and high-performance television standards, it is
critical that we retain the currently used television spectrum which
provides great value to the information society.”
ITU Membership will consider the spectrum requirements for television at
the next World Radiocommunication Conference in November 2015.
