Abstract

Disclosed are systems, methods, and non-transitory computer-readable media for distributed DCP over internet. A client-side digital content delivery device receives a digital cinema package (DCP) for a digital movie from a remote digital content delivery system. The DCP includes a unique digital watermark applied by the content delivery system. In response to receiving an input to cause playback of the digital movie, the client-side digital content delivery device compares a unique device identifier for a display device paired to the client-side digital content delivery device to an authorized unique identifier. If the unique device identifier matches the authorized unique identifier, the client-side digital content delivery device uses the DCP to causes presentation of the digital movie by the display device paired to the client-side digital content delivery device.

Claims (32)

1. A method comprising:

receiving, by a client-side digital content delivery device, an encrypted digital cinema package (DCP) for a digital movie, the encrypted DCP received from a digital content delivery system that is remote to the client-side digital content delivery device, the encrypted DCP including a first persistent unique digital watermark antecedently applied to the encrypted DCP by the digital content delivery system;

receiving from the digital content delivery system, a first authenticated unique identifier antecedently loaded onto the digital content delivery system, the first authenticated unique identifier corresponding with a first display device paired to the client-side digital content delivery device;

receiving, by the client-side digital content delivery device, a first Key Delivery Message (KDM) corresponding with the encrypted DCP and the first display device paired to the client-side digital content delivery device, the first KDM including a key for decrypting the encrypted DCP;

accessing a unique device identifier corresponding with the first display device, including comparing the unique device identifier with the first authenticated unique identifier;

decrypting, based on the comparison of the unique device identifier with the first authenticated unique identifier and by the client-side digital content delivery device, the encrypted DCP using the key included in the first KDM; and

using the decrypted DCP to cause presentation of the digital movie according to the first KDM and by the first display device paired to the client-side digital content delivery device,

wherein using the decrypted DCP to cause presentation of the digital movie by the display device comprises:

applying a client-side digital watermark to data included in the DCP, yielding watermarked presentation data, the client-side digital watermark including first session data associated with the presentation of the DCP; and

transmitting the watermarked presentation data to the display device.

2. The method of claim 1 , wherein the DCP is received from the digital content delivery system via a communications network including at least one of an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wide area network (WAN), or a cellular telephone network.

3. The method of claim 1 , wherein the DCP is received from the digital content delivery system using an internet protocol.

4. The method of claim 1 , wherein the client-side digital content delivery device is communicatively coupled, via a physical connector, to the first display device.

5. The method of claim 2 , wherein the client-side digital watermark comprises session data associated with the presentation of the DCP.

6. The method of claim 1 , wherein the DCP is received from the digital content delivery system using an internet protocol.

7. A client-side digital content delivery device comprising:

one or more computer processors; and

one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the one or more computer processors to perform operations comprising:

receiving, by a client-side digital content delivery device, an encrypted digital cinema package (DCP) for a digital movie, the encrypted DCP received from a digital content delivery system that is remote to the client-side digital content delivery device, the encrypted DCP including a first persistent unique digital watermark antecedently applied to the encrypted DCP by the digital content delivery system;

receiving from the digital content delivery system, a first authenticated unique identifier antecedently loaded onto the digital content delivery system, the first authenticated unique identifier corresponding with a first display device paired to the client-side digital content delivery device;

receiving, by the client-side digital content delivery device, a first Key Delivery Message (KDM) corresponding with the encrypted DCP and the first display device paired to the client-side digital content delivery device, the first KDM including a key for decrypting the encrypted DCP;

accessing a unique device identifier corresponding with the first display device, including comparing the unique device identifier with the first authenticated unique identifier;

decrypting, based on the comparison of the unique device identifier with the first authenticated unique identifier and by the client-side digital content delivery device, the encrypted DCP using the key included in the first KDM; and

using the decrypted DCP to cause presentation of the digital movie according to the first KDM and by the first display device paired to the client-side digital content delivery device,

wherein using the decrypted DCP to cause presentation of the digital movie by the display device comprises:

applying a client-side digital watermark to data included in the DCP, yielding watermarked presentation data, the client-side digital watermark including first session data associated with the presentation of the DCP; and

transmitting the watermarked presentation data to the display device.

8. The client-side digital content delivery device of claim 7 , wherein the DCP is received from the digital content delivery system via a communications network including at least one of an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wide area network (WAN), or a cellular telephone network.

9. The client-side digital content delivery device of claim 7 , wherein the DCP is received from the digital content delivery system using an internet protocol.

10. The client-side digital content delivery device of claim 7 , wherein the client-side digital content delivery device is communicatively coupled, via a physical connector, to the first display device.

11. The client-side digital content delivery device of claim 7 , wherein the client-side digital watermark comprises session data associated with the presentation of the DCP.

12. The client-side digital content delivery device of claim 7 , wherein the DCP is received from the digital content delivery system using an internet protocol.
