摘要

Invention patent: equipment and method for distribution of programs of image and audio of high quality for remote locations.There are provided an equipment and a method for distribution of materials of audio or visual programming of high quality from one or more centres (102) for one or more of the localPresentation (56, 104) such as cinemas, using high data rate links such as satellites (106).In the distribution center (102) a system generation source (108) generates a signal of electronic program from an analog signal.A system of compression / coding or scrambling device (110) encodes and encrypts a digital electronic signal and a modulation system and transmission (114) processes the signal for transmission viaThe satellite (106). A network management system (112) in the distribution center (102) controls the operation of the distribution center.In the film (56) or other location, a receiver / demodulator (120) receives the signal of the programming transmitted using the satellite (106).A system management of Cinema (122) then controls the storage, direction, decoding and presentation of material programming received.Arrangements for storage (124a to 124n) in the system of film (104a to 104n) provides centralized storage of the material of the programming.The material of the programming is directed via a local area network to designated auditoriums, several of which may operate within a system of Cinema (104a to 104n).In each auditorium, the material of programming is decompressed and decoded for display using electronic projection equipment (132a) and sound systems of the auditorium (134a) standard.
