In vision signing involves translating a programme's dialogue into British Sign Language (BSL). Sign language is a visual language with a unique syntax having its own independent grammar and vocabulary.
An interpreter, whose image is superimposed on the broadcasted programme, carries out that work.
The service is aimed at deaf people, and where practicable, the style of the interpreter or presenter should be appropriate for an audience mainly based in Wales, or those able to access S4C Digital on the Sky platform and are interested in Welsh culture, issues etc.
As a viewer you don't have to do anything different, as the signing is available to all viewers.
Signed programmes are normally shown on Saturday afternoon or you can watch online.
