| Accessibility profiles for IPTV systems |
 |
Recommendation ITU-T H.702 defines three profiles for accessibility features in Internet protocol television (IPTV) systems, with increasing levels of support. The Basic profile provides an entry-level support of accessibility, whereas the Main profile provides the widest range of features. The Enhanced profile provides the middle level support between the Basic profile and the Main profile. Accessibility information is information such as captions, sign language streams and audio description that are sent separately from video contents to IPTV terminal devices. By defining the above profiles, persons with disabilities can choose more easily the terminal devices that have the functions they need.
This version of the Recommendation includes the accessibility profiles for cognitive disabilities and an appendix with an example for an ITU-T H.702 based system. It also and harmonizes the latest term definitions. |
