Other patrons' views of the movie screen are different from yours. Moviegoers who use the Rear Window system pay normal ticket prices. There is no additional cost to the moviegoer to see the captions. DVS Theatrical makes it possible for exhibitors to provide descriptive narration for their blind and visually impaired patrons, without broadcasting it to the entire audience and without the need for special prints or screenings. The descriptive narration is fed via infrared or FM transmitter to a small portable receiver, enabling blind and visually impaired moviegoers to hear the descriptions on headsets from any seat in the theater.
Descriptive narration is a way of making visual media more meaningful to people with vision loss.
Narrated descriptions provide information about key visual elements such as actions, settings, facial expressions, costumes, and scene changes. The descriptions are inserted into pauses in the soundtrack and do not interfere with the dialogue. Descriptions are narrated and recorded onto an audiotape or disc that can be synchronized to the film as it is projected. Conventional movie theaters use the DTS digital audio system to play the descriptions. The descriptive narration resides on a CD that plays alongside the other discs in the DTS player.
