Abstract

Cinematic information including cinemagraphic video images and, optionally, corresponding audio data are converted into a digital format and RF transmitted from a central site to a movie theater. The digital data received at the movie theater is provided to a digital projector which projects sequential frames of cinemagraphic video data onto a screen. The corresponding audio data is converted into audible sounds sequentially with the projection of each frame of cinemagraphic video images. Orders for cinematic information may be placed via a communication network, such as a private or public telephone network.
