  • the assignee of the present invention has heretofore developed a system and method for use in distributing digitally recorded motion pictures to motion picture viewing locations, such as theaters, for viewing by an audience.
  • This system and method is disclosed in US Patent Application Serial No. 09/245.153, filed February 4, 1999, entitled "Digital Distribution and Viewing of Feature Length Movies in Theaters" and is assigned to the assignee of the present invention.
  • the present invention addresses these concerns as well as those of distributing digital data for various types of applications. Accordingly, it is an objective of the present invention to provide for a secure system and method for distributing and displaying digital data, such as digitally recorded feature length movies, at remote viewing locations.
  • the present invention provides for a system and method for use in distributing digital video data, such as live video or digitally recorded motion pictures, for example, to remotely located viewing locations, for viewing by an audience, in a secure manner in order to preclude unauthorized duplication and/or piracy.
  • the system and method involve secure transmission of the digital video data, such as the live video or digitally recorded motion picture, by way of a data broadcasting system, which may comprise a satellite, for example, from a production or distribution facility to the remote viewing locations at which the digital video data is to be displayed.
  • the transmission, reception and display of the digital video data (live video or digitally recorded motion picture) using a digital projector are handled in a secure manner in accordance with the principles of the present invention. More particularly, the system and method provides for an encrypted video signal corresponding to the digital video data (live video or digitally recorded motion picture) to be generated at the production or distribution facility which is broadcast by way of the data broadcasting system to one or more remote viewing locations. At the remote viewing locations, the encrypted video signal is processed by an integrated receiver and decoder unit (IRD) including a decryption device where it is received and decrypted. The decrypted video signal then passes immediately to a second encryption device which re-encrypts the video signal. The IRD unit and the second encryption device are located inside a secured lock box.
  • IRD integrated receiver and decoder unit
  • the re-encrypted video signal may be stored in a storage device for later display.
  • the re-encrypted signal either from the second encryption device or storage device, is then passed to the digital projector.
  • a decryption device located within the digital projector decrypts the re -encrypted signal transmitted from the secure lock box.
  • the decryption device is coupled to a motherboard of the digital projector by way of cables that enable the decryption device to draw power, and to couple the decrypted video signal directly to a video processor used by the digital projector.
  • an encrypted video data is transmitted to a remotely located viewing location.
  • the encrypted video data is received and decrypted at the remotely located viewing location.
  • the decrypted video data is then re-encrypted and optionally stored.
  • the re-encrypted video data is decrypted in a digital projector to produce the original video data.
  • the video data is then processed to display it.
  • the present system and method thus provides for a secure digital video path from the production or distribution facility to the remotely located digital projector.
  • the video signal corresponding to the live video or recorded motion picture is encrypted and subsequently broadcast, the signal will not be discernable by non- licensed or unauthorized viewers, and in the event the signal is intercepted, it will not be readily recoverable as viewable or otherwise useable data.

Abstract

L'invention concerne un système et un procédé de distribution de données vidéo numériques à un point de visualisation (30) de films cinématographiques situé à distance, d'une manière sécurisée. Les données vidéo numériques sont codées (16) au niveau d'une unité de distribution (11). Les données vidéo codées (16) sont transmises au moyen d'un système (11) de radiodiffusion de données au point de visualisation distant (30). Au niveau du point de visualisation distant (11), les données vidéo codées (16) sont reçues par une unité récepteur et décodeur intégrée (22) (IRD) comprenant un dispositif de décodage (23) et elles sont décodées. Les données vidéo décodées (24) sont ensuite placées immédiatement dans un second dispositif de codage (25) lequel recode les données vidéo lesquelles sont facultativement stockées. L'IRD (23) et le dispositif de codage (25) sont situés à l'intérieur d'un emplacement sécurisé (22) tel qu'un boîtier verrouillé. Les données vidéo recodées sont ensuite transférées vers le projecteur numérique (27). Un second dispositif de codage (28) est situé à l'intérieur du projecteur numérique et décode les données vidéo préalablement recodées. Le second dispositif de codage (28) est couplé à une carte mère du projecteur numérique (27) au moyen de câbles lui permettant de tirer de l'énergie, et de coupler les données vidéo codées directement au processeur vidéo utilisé par le projecteur numérique (27).
