ITU-EBU Joint Workshop on Accessibility to Broadcasting and IPTV ACCESS for ALL
Geneva, Switzerland, 23 – 24 November 2010 Contact: 


Christoph Jung, Fraunhofer IGD / EU project GUIDE: "European Project GUIDE: User centered multi-modal interaction design for hybrid TV applications and platforms"

The European project GUIDE “Gentle user interfaces for elderly people” ( is developing a software framework which allows developers to efficiently integrate accessibility features into their applications. GUIDE puts a dedicated focus on the emerging Hybrid TV platforms and services (Connected TVs, Set-Top Boxes, etc.), including application platforms as HBBTV as well as proprietary middleware solutions of TV manufacturers. These platforms have the potential to become the main media terminals in the users’ homes, due to their convenience and wide acceptance. Especially for users of the elderly society applications such as home automation, audiovisual communication or continuing education can help to simplify their daily life, stay connected in their social network and enhance their understanding of the world.

Currently the GUIDE consortium is conducting user trials with elderly people, which aim at gathering data for user modeling and to evaluate acceptance of multi-modal interaction schemes for the users. This presentation will provide an overview of the evaluation approach and preliminary outcomes from the tests.

Audio Description (AD) is an additional audio track with narration for all, but especially for blind and visually impaired people. This service can be delivered using different techniques: over DVB-T with the help of a second pair of audio channels (broadcast/broadcast) or with the help of a shared distribution, broadcast and broadband via the air and the web (hybrid solution), even a fully web based solution can be considered (WebTV). Because the AD audio track can be delivered using technologies that are not currently tested for this purpose it is regarded as an emerging access service.

During the project we posed and tested five different scenarios. Several tests were conducted in order to validate these. Tests focused on evaluating usability, usefulness and quality of the audio description services. In this presentation the scenarios are presented graphically followed by results and conclusions of the evaluation tests. As each of the different scenarios implies a differentiated service, the results are presented individually for each of the five evaluated scenarios.
Beat Kleeb/Donald Shelton, World Federation of the Deaf: The Deaf perspective: Audio-Visual Media without Audio

Millions of people worldwide suffer from hearing problems, an invisible and therefore an often neglected disability.
This disability prevents access to most audio-visual products. But an increasing number of recommendations and laws require access for all.
But where starts real accessibility for all and what are the rationales for such actions?
What are the tools to make audio-visual products understandable without the audio part? What are the technological problems for transmitting sign language interpretation and captioning? And what are the technological requirements to ensure that accessible audio-visual products are really arriving on the screen of the consumer?

TV is a central part of life for most people. This is no different for disabled people. New digital and online forms of television can be a good thing, but often bring barriers to disabled people.

Both programme content and TV receivers need to be made accessible so that everyone can benefit fully from TV. Regulation has its role to play, and the reference point for all regulation in this field should be the UN Convention on the Rights of Persons with Disabilities.

EDF and EBU have been working with industry to remove barriers, but with so far only partial success. We need joined up action from users, policy makers (Commission ITU) Standards bodies, broadcasters, TV manufacturing industry to ensure end-to-end accessibility.
Ulrike Haltrich, Sony, IEC/TC – 100

The accessibility and usability project was started in IEC TC100 with a survey which was designed and distributed to the IEC TC100 P-members to obtain information about the related issues, public policies and activities. As a result the project team produced the Technical Report TR 62678 Audio, Video and Multimedia Systems and Equipment Activities and Considerations related to Accessibility and Usability which attempts to explain the possible relevance of accessibility and usability to the IEC TC100 programme of work. The TR provides information on accessibility and usability terms, activities, completed and ongoing standards, technical reports, projects and specifies user needs that may or may not apply to audio, video and multimedia systems and equipment. Comments about demographics and public policies are included. A checklist of accessibility and usability considerations is also included. Industry experts may or may not apply this information when they evaluate opportunities to integrate support for accessibility and usability in their work.
