Abstract

A software application program and method are disclosed for allowing blacked-out television content to be viewed when restrictions on the television content have been lifted. The present system may be part of a software platform for providing television content to subscribers via a broadband IP network service provider such as a telephone company. For situations where a content owner has made deferred rights to television content available, the present system employs a deferred rights management software application program for affecting the download and storage of restricted content to subscribers. The restricted content is downloaded to subscribers in an encrypted format, and remains locked and unusable by subscribers as long as the license restrictions last. When the license restrictions are lifted, the SMS 116 transmits decryption keys allowing decryption and viewing of the content.

Claims

1. A method of providing content for a client device via a network, the content being subject to a license restriction, the method comprising the steps of:

a) transmitting the content to the client device in a format which prevents viewing of the content on a display associated with the client device; and

b) enabling the client device to present the content on the display in a normal format that allows viewing of the content when the license restriction on the content has been lifted.

2. A method as recited in claim 1, wherein said step b) of enabling the client device to present the content in a normal format that allows viewing of the content when the license restriction on the content has been lifted comprises the step of downloading one or more decryption keys to the client device when the license restriction on the content has been lifted.

3. A method as recited in claim 1, further comprising the step c) of authenticating a client device prior to enabling the client device in said step b).

4. A method as recited in claim 1, further comprising the step c) of disabling the client device from presenting content in a normal format if a window during which the restrictions were lifted has expired.

5. A method as recited in claim 1, further comprising the step c) of presenting a graphical user interface over the display including an option to view the content when the license restriction on the content has been lifted.

6. A method as recited in claim 5, said step a) of transmitting the content to the client device being performed upon selecting the option to view the content when the license restriction on the content has been lifted in said step c).

7. A method as recited in claim 1, wherein the content is television content.

8. A computer-readable medium having computer-executable instructions for programming a processor to perform a method of providing content for a client device via a network, the content being subject to a license restriction, the method comprising the steps of:

a) storing the content in an encrypted format; and

b) deferring decryption of the content until the license restriction on the viewing of the content has been lifted.

9. A computer-readable medium as recited in claim 8, further comprising the step c) of authenticating the client device prior to said step a) of storing the content in an encrypted format.

10. A computer-readable medium as recited in claim 8, said step a) of storing the content in an encrypted format comprising the step of storing the content on a storage device associated with the client device.

11. A computer-readable medium as recited in claim 8, said step a) of storing the content in an encrypted format comprising the step of storing the content on a storage device remote from the client device and connected to the client device via the Internet.

12. A method of providing content for a client device via an IP network, the method comprising the steps of:

a) receiving one or more license restrictions on the rights to view the content;

b) receiving one or more conditions which must be satisfied in order for the one or more restrictions to be lifted and the content to be normally displayed on a display associated with the client device;

c) storing the content in an encrypted format; and

d) enabling the client device to present the content in an unencrypted format on the display when the one or more conditions of said step b) are satisfied.

13. A method as recited in claim 12, wherein said step b) of receiving one or more conditions which must be satisfied in order for the restrictions to be lifted and the content to be normally displayed on the display comprises the step of receiving an indication that a preset period of time must pass before the one or more restrictions are lifted.

14. A method as recited in claim 12, wherein said step b) of receiving one or more conditions which must be satisfied in order for the restrictions to be lifted and the content to be normally displayed on the display comprises the step of receiving a window having a start time and an end time within which content can be viewed.

15. A method as recited in claim 12, wherein said step b) of receiving one or more conditions which must be satisfied in order for the restrictions to be lifted and the content to be normally displayed on the display comprises the step of receiving a maximum number of times the content may be displayed.

16. A method as recited in claim 12, wherein said step b) of receiving one or more conditions which must be satisfied in order for the restrictions to be lifted and the content to be normally displayed on the display comprises the step of authenticating the client device.

17. A method as recited in claim 12, wherein said step d) of enabling the client device to present the content in an unencrypted format on the display when the one or more conditions of said step b) are satisfied comprises the step of downloading one or more decryption keys to the client device for decrypting the content.

18. A method as recited in claim 12, said step c) of storing the content in an encrypted format comprising the step of storing the content on a storage device associated with the client device.

19. A method as recited claim 12, said step c) of storing the content in an encrypted format comprising the step of storing the content on a storage device remote from the client device and connected to the client device via the Internet.

20. A method as recited in claim 12, wherein said step d) comprises the steps of downloading the encrypted content from the storage device to the client device, downloading a decryption key to the client device, and applying the decryption key to the encrypted content to decrypt the content.
