Firstly, make sure you have the latest version of the ITV Hub app installed.
Audio described programmes have their own programme category. Categories are across the top of the app. Scroll right to find the category called AD. The ITV Hub app should default to this category if you have a native screen reader enabled (such as VoiceOver or TalkBack).
We make a limited number of sign language translated programmes available on ITV Hub at the moment. We intend to include all translated versions of shows available by the end of 2021. At that point we intend to introduce a ‘Signed’ category to ITV Hub.
