audio description

"Audio description" (also referred to as "video description") is the insertion of audio-narrated descriptions of a television program's key visual elements into natural pauses in the program's dialogue, making video programming more accessible to individuals who are blind or visually impaired.

Beginning July 1, 2012, under FCC requirements, Freeform will provide 50 hours of audio-described primetime programming per calendar quarter, at an average of four hours per week, via the Secondary Audio Programming (SAP) System.
