Abstract

A system 100 includes a content repository 274 storing a content file and a video transport processing system. The video transport processing system 223 receives a plurality of conditional access information, receives the content file from the content repository, encrypts the content file using the plurality of conditional access information to from an encrypted content file, determines broadband information, forms a content stream from the encrypted content file and the broadband information and stores the content stream in the content repository.

Claims

1. A method comprising:

storing a content file in a content repository;

communicating a plurality of conditional access information to a video transport processing system;

communicating the content file to the video transport processing system;

encrypting the content file using the plurality of conditional access information to from an encrypted content file;

determining broadband information;

forming a content stream from the encrypted content file and the broadband information; and

storing the content stream in the content repository.

2. A method as recited in claim 1 wherein the broadband information comprises a material identification.

3. A method as recited in claim 1 wherein the broadband information comprises a start of file indicator.

4. A method as recited in claim 1 wherein the broadband information comprises an end of file indicator.

5. A method as recited in claim 1 wherein the broadband information comprises a high definition indicator

6. A method as recited in claim 1 wherein the broadband information comprises a first portion inserted in the content stream prior to the encrypted file and a second portion after the encrypted content file.

7. A method as recited in claim 1 further comprising prior to storing a content file, receiving a content file from a content source.

8. A method as recited in claim 7 further comprising after storing the content stream, communicating the encrypted content file to a user device.

9. A method as recited in claim 8 further comprising after storing the content stream, communicating the content stream to the user device through a satellite.

10. A method as recited in claim 8 further comprising after storing the content stream, communicating the content stream through a broadband connection.

11. A method as recited in claim 8 further comprising after storing the content stream, communicating the content stream file through a wireless connection.

12. A method as recited in claim 8 further comprising after storing the encrypted content file, communicating the encrypted content file through a terrestrial communication network.

13. A method as recited in claim 8 wherein the user device is a satellite television set top box having a digital video recorder therein.

14. A method as recited in claim 13 wherein storing the content comprises storing the content in the digital video recorder.

15. A method as recited in claim 1 wherein the conditional access information comprises control words.

16. A system comprising:

a content repository storing a content file; and

a video transport processing system receiving a plurality of conditional access information, receiving the content file from the content repository, encrypting the content file using the plurality of conditional access information to from an encrypted content file, determining broadband information, forming a content stream from the encrypted content file and the broadband information and storing the content stream in the content repository.

17. A system as recited in claim 16 wherein the broadband information comprises a material identification.

18. A system as recited in claim 16 wherein the broadband information comprises a start of file indicator.

19. A system as recited in claim 16 wherein the broadband information comprises an end of file indicator.

20. A system as recited in claim 16 wherein the broadband information comprises a high definition indicator.

21. A system as recited in claim 16 wherein the broadband information comprises a first portion inserted in the content stream prior to the encrypted file and a second portion after the encrypted content file.

22. A system as recited in claim 16 further comprising a content source communicating the content file to the content repository.

23. A system as recited in claim 16 wherein the content repository stores the encrypted content file.

24. A system as recited in claim 23 further comprising a content distribution system communicating the encrypted content file to a user device.

25. A system as recited in claim 24 wherein the content distribution system communicates the encrypted content file to the user device through a satellite.

26. A system as recited in claim 24 wherein the content distribution system communicates the encrypted content file to the user device through a broadband connection.

27. A system as recited in claim 24 wherein the content distribution system communicates the encrypted content file to the user device through a wireless connection.

28. A system as recited in claim 24 wherein the user device comprises a satellite television set top box having a digital video recorder therein.

29. A system as recited in claim 24 wherein the conditional access information comprises control words.
