Abstract

A content delivery system comprising a content database storing a content item and a content license; a video server configured to retrieve the content item and the content license from the content database and to send them to a player device; a registration server configured to receive credentials from a user player device, to generate user information from the credentials, to forward the user information to an application server; an application server configured to generate a personalised player application for the user player device; and a license server configured to receive a content license and a user identity from the user player device, to check with the registration server that a user corresponding to the user identity is authorized to access the content item, to decrypt the content license using a system license key and re-encrypt the decrypted content license using a user license key to obtain a user license, and to send the user license to the user player device. Also provided is a content rendering method.

Claims

1-11. -11. (canceled)

12. A method of rendering a content item, the method comprising the steps, in a device having a processor executing a player, of:

rendering the content item;

and wherein, at at least one point of time during execution of the method, it comprises;

verifying a presence of a proximity server; and

stopping the rendering of the content item in case the proximity server is not present.

13. The method of claim 12, wherein the device has a user identity and the player has been personalised to comprise the user identity and a user license key for the device, the method further comprising the steps of:

sending a content license for the content item and the user identity to a license server;

obtaining a user license for the content item from the license server;

decrypting the user license using the user license key to obtain a scrambling key; and

descrambling the content item using the scrambling key.

14. The method of claim 13, further comprising the step, between the descrambling step and the rendering step, of watermarking the content.

15. The method of claim 14, wherein the player has further been personalised to comprise a user watermark identity and the content is watermarked with the user watermark identity.

16. The method of claim 13, further comprising the prior steps of sending user credentials to a registration server and of receiving the player.

17. The method of claim 13, further comprising the step of obtaining the content item and the content license.

18. The method of claim 13, wherein user license has been generated from the content license.

19. The method of claim 12, wherein the presence of a proximity server is defined in function of a distance between the proximity server and said device.

20. A content delivery system wherein it comprises

a player device being able to receive and render at least one content item;

a proximity server;

means for verifying a presence of the proximity server at at least one point of time during reception of the at least one content item by the player device; and

means for stopping the player device in case the proximity server is not present.

21. The content delivery system of claim 20, further comprising:

a content database configured to store at least one content item and a corresponding content license;

a video server configured to retrieve a content item and a corresponding content license from the content database and to send the retrieved content item and corresponding content license to the player device;

an application server configured to receive user information from the registration server, to generate a personalised player application for the user player device and to deliver the personalised player application to the user player device;

a license server configured to receive a content license and a user identity from the user player device, to check with the registration server that a user corresponding to the user identity is authorized to access the content item, to decrypt the content license using a system license key and re-encrypt the decrypted content license using a user license key to obtain a user license, and to send the user license to the user player device; and

a the proximity server configured to participate in a challenge-response protocol with the user player device.

22. The content delivery system of claim 21, further comprising a registration server configured to receive credentials from a user player device, to generate the user information from the credentials, to forward the user information to an application server.

23. The content delivery system of claim 21, further comprising a system player device comprising the system license key, the system player device being configured to receive the content item and the corresponding content license, to decrypt the content license using the system license key to obtain a scrambling key, to descramble the content item using the scrambling key, and to render the descrambled content item.

24. The content delivery system of claim 23, wherein the system player device is further configured to embed a watermark in the descrambled content item before rendering.
