Secure distribution of video on-demand

1. A method, comprising:

processing, by a remote server of a distribution center of a content provider, a video program encrypted in a first encrypted form received from at least one programming source to produce a modified version of the video program;

processing, by the remote server, the modified version of the video program to produce a video program in a second encrypted form;

receiving, by the remote server, a user request for the video program; and

as a response to the user request, transmitting, by the remote server, the video program in the second encrypted form to a user device using a portion of a distribution network of the content provider.

2. The method of claim 1 , wherein the video program encrypted in the first encrypted form is a video-on demand program encrypted in the first encrypted form, the user request is requesting the video-on demand program, and the distribution center is located at a location of the content provider.

3. The method of claim 1 , further comprising: transmitting a decryption key to the user device, the decryption key being necessary to decrypt the video program in the second encrypted form.

4. The method of claim 3 , wherein the decryption key and the video program in the second encrypted form are transmitted to the user device separately.

5. The method of claim 1 , wherein the at least one programming source includes one or more of the following: a broadcast source, a premium broadcast source, or a video-on-demand source.

6. The method of claim 1 , wherein transmitting the video program in the second encrypted form to the user device uses a first communications channel of the distribution network; and the method further comprises:

transmitting a decryption key to the user device using a second communications channel of the distribution network.

7. The method of claim 1 , wherein the video program in the second encrypted form is encrypted according to a Data Encryption Standard (DES).

8. The method of claim 1 , wherein the video program in the second encrypted form is multiplexed with other signals to create a multiplexed signal for transmission to the user device.

9. A system, comprising:

a distribution center of a content provider comprising a remote server, the remote server configured to:

process a video program encrypted in a first encrypted form received from at least one programming source to produce a modified version of the video program,

process the modified version of the video program to produce a video program in a second encrypted form,

receive a user request for the video program, and

as a response to the user request, transmit the video program in the second encrypted form to a user device using a portion of a distribution network of the content provider.

10. The system of claim 9 , wherein the video program encrypted in the first encrypted form is a video-on demand program encrypted in the first encrypted form, the user request is requesting the video-on demand program, and the distribution center is located at a location of the content provider.

11. The system of claim 9 , wherein the remote server is configured to cause transmission of a decryption key to the user device, the decryption key being necessary to decrypt the video program in the second encrypted form.

12. The system of claim 11 , wherein the decryption key and the video program in the second encrypted form are transmitted to the user device separately.

13. The system of claim 9 , wherein the at least one programming source includes one or more of the following: a broadcast source, a premium broadcast source, or a video-on-demand source.

14. The system of claim 9 , wherein the video program in the second encrypted form is transmitted to the user device using a first communications channel of the distribution network; and the remote server is configured to:

transmit a decryption key to the user device using a second communications channel of the distribution network.

15. The system of claim 9 , wherein the video program in the second encrypted form is encrypted according to a Data Encryption Standard (DES).

16. The system of claim 9 , wherein remote server is configured to multiplex the video program in the second encrypted form with other signals to create a multiplexed signal for transmission to the user device.

17. A method, comprising:

processing, by a remote server of a distribution center of a content provider, a video program encrypted in a first encrypted form received from at least one programming source to produce a modified version of the video program;

processing, by the remote server, the modified version of the video program to produce a video program in a second encrypted form;

receiving, by the remote server, a user request; and

as a response to the user request, transmitting, by the remote server, the video program in the second encrypted form to a user device using one of the content provider's distribution networks.

18. The method of claim 17 , wherein the video program encrypted in the first encrypted form is a video-on demand program encrypted in the first encrypted form, the user request is requesting the video-on demand program, and the distribution center is located at a location of the content provider.

19. The method of claim 17 , wherein the at least one programming source includes one or more of the following: a broadcast source, a premium broadcast source, and a video-on-demand source.

20. A system, comprising:

a distribution center of a content provider comprising a remote server, the remote server configured to:

process a video program encrypted in a first encrypted form received from at least one programming source to produce a modified version of the video program,

process the modified version of the video program to produce a video program in a second encrypted form,

receive a user request for the video program, and

as a response to the user request, transmit the video program in the second encrypted form to a user device using one of the content provider's distribution networks.
