rear-window captioning
n.— «There are several companies that will add text to some (not all) current run films; one is Mopix, which provides rear-window captioning. The text is displayed from a LED screen in the back of the theater, under the cinema projector; the text is reversed, and the theater provides the hearing impaired viewer with a piece of clear plastic attached to a flexible stand that fits in the cup holder of the theater seat. The LED text is reflected off the clear plastic, which the viewer reads while watching the film simultaneously.» —“A movie about the deaf, but not for the deaf” by Kathryn Hill L.A. Voice (California) Sept. 10, 2005. (source: Double-Tongued Dictionary)
