ITU-T H.702 (11/2015)

Accessibility profiles for IPTV systems

This Recommendation defines three profiles for accessibility features in IPTV systems, with increasing levels of support. While the Basic Profile provides an entry-level support of accessibility, 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.
