The system is now in commercial use in sixteen theatres in the United States. It is also being used in specialized theatres in theme parks such as Disney World. RW captioned movies are available at the same time as the general release of the movie. As more theatres install the technology NCAM intends to increase the number of films captioned each year. An advantage of the Rear Window system is that special showings are not required.
Patrons requiring captioning can attend any viewing in an equipped theatre.
However, the number of closed caption movies is still small, limiting the viewing options available to caption users. These systems transmit the captions to a seat mounted TV type screen, a hand held monitor, or a heads-up viewing device similar to a pair of spectacles. This eliminates the need for a LED display at the rear of the theatre. This would involve converting theatres to use a cinema quality digital video system. Films would be transmitted to theatres via satellite or fibre optic land lines.
