Question 26/16 – Accessibility to multimedia systems and services

(Continuation of Question 26/16)


The capability to handle different information media and control actions varies within wide boundaries among users of telecommunications and multimedia services. The variation may have a cause in age-related functional limitations, in disabilities, and in other natural causes. With the ageing populations in large parts of the world, many telecom users will have sensory and motor limitations. It is important to meet this wide variety in capabilities in the original design of telecommunication services so that an increasing number of users can make benefit of the mainstream services. Legislation in many countries is also beginning to follow the trend of requiring design for all in all forms of communications services and communications devices.

Multimedia systems and services have great opportunities to provide valuable and accessible information in a way that the individual user can control, if care is taken from the beginning in inclusive design of these services, making them accessible to as many users as possible.

The accessibility activities in Study Group 16 and its predecessors have created the following documents:

Complemented by a number of additions to other Recommendations, the total conversation concept was founded for conversation in video, text and voice as an accessible superset of video telephony, text telephony and voice telephony.

It is the task of this Question to engage in standardization activities leading to services and systems designed for all. Consideration should be given to services in new generation networks with fixed as well as mobile features.

The group also has a task to promote and enhance accessibility as a normal part of ITU work.
