Described Video (DV)

Described Video (DV) uses a secondary audio track synchronized with media to provide aural representation of visual narrative of a program's non-verbal elements that may include surroundings, costumes and body language. The description is added during pauses in dialogue, and enables people to form a mental picture of what is happening in the program. Described video typically uses a separate audio track that is added to the program after the program has been completed. AMI programming that utilizes DV include Murdoch Mysteries, Elementary, Corner Gas and Holmes Inspection..
