Abstract
A novel system and method for secure electronic delivery of motion pictures in digital format to many end users simultaneously. In particular, the system comprises a headend system and a theater system. The headend system comprises a baseband processing system which receives analog cinema film as input, a storage system which receives digitized cinema files from the baseband processing system, a radio frequency transmission system which communicates cinema and data files to and from various users as a radio frequency bit stream, and a management system which controls transmission and storage of cinema and data files. The theater system comprises transmission line interfaces at theaters designated to receive cinema and data files from the headend system, receiver-decoders which receive the radio frequency bit stream and produce decoded cinema and data files at baseband, storage playback systems which stores cinema and data files until needed, secure projector systems which playback cinema files, an automation/scheduling system which directs playback of cinema files in the secure projector systems as authorized by the management system, and a reverse channel which provides data back to the headend system from the theaters. A preferred version of the present invention further comprises a creator/editor's system which allows authorized viewing and editing of cinema files by creators and editors. The creator/editor's system provides capability for editing and baseband processing of cinema files at remote locations, and transmits edited cinema files back to the headend system.
