Abstract

A method for use in playing content that is made up of data includes establishing in a device a physical media storing a first portion of the data making up the content, receiving a streamed second portion of the data making up the content, wherein the second portion of the data includes essential information for reconstructing the content from the first portion of the data, and playing the content by combining the first portion of the data with the second portion of the data to correctly reconstruct the content. A method for use in enhancing security of content that is made up of data includes removing information from the data making up the content that is essential for playing the content.

Claims

1. A method for use in playing content that is made up of data, comprising:

establishing in a device a physical media storing a first portion of the data making up the content;

receiving a streamed second portion of the data making up the content, wherein the second portion of the data includes essential information for reconstructing the content from the first portion of the data; and

playing the content by combining the first portion of the data with the second portion of the data to correctly reconstruct the content.

2. A method in accordance with claim 1, wherein the second portion of the data making up the content comprises at least a portion of one or more I pictures.

3. A method in accordance with claim 1, wherein the second portion of the data making up the content comprises encrypted information.

4. A method in accordance with claim 1, wherein the second portion of the data making up the content comprises less information than the first portion of the data making up the content.

5. A method in accordance with claim 1, wherein the first portion of the data making up the content comprises unsecured data.

6. An apparatus for use in playing content that is made up of data, comprising:

a physical media storing a first portion of the data making up the content; and

a processing system configured to receive a streamed second portion of the data making up the content, wherein the second portion of the data includes essential information for reconstructing the content from the first portion of the data;

wherein the processing system is further configured to play the content by combining the first portion of the data with the second portion of the data to correctly reconstruct the content.

7. An apparatus in accordance with claim 6, wherein the second portion of the data making up the content comprises at least a portion of one or more I pictures.

8. An apparatus in accordance with claim 6, wherein the second portion of the data making up the content comprises encrypted information.

9. An apparatus in accordance with claim 6, wherein the second portion of the data making up the content comprises less information than the first portion of the data making up the content.

10. An apparatus in accordance with claim 6, wherein the first portion of the data making up the content comprises unsecured data.

11. A storage medium storing a computer program executable by a processor based system, the computer program causing the processor based system to play content that is made up of data by executing steps comprising:

retrieving a first portion of the data making up the content from a physical storage media;

receiving a streamed second portion of the data making up the content, wherein the second portion of the data includes essential information for reconstructing the content from the first portion of the data; and

playing the content by combining the first portion of the data with the second portion of the data to correctly reconstruct the content.

12. A storage medium in accordance with claim 11, wherein the second portion of the data making up the content comprises at least a portion of one or more I pictures.

13. A storage medium in accordance with claim 11, wherein the second portion of the data making up the content comprises encrypted information.

14. A storage medium in accordance with claim 11, wherein the second portion of the data making up the content comprises less information than the first portion of the data making up the content.

15. A storage medium in accordance with claim 11, wherein the first portion of the data making up the content comprises unsecured data.

16. A method for use in enhancing security of content that is made up of data, comprising:

removing information from the data making up the content that is essential for playing the content;

establishing a remainder of the data after the removing step as a first portion of the data; and

establishing the removed essential information as a second portion of the data.

17. A method in accordance with claim 16, wherein the step of removing information from the data making up the content comprises removing at least a portion of one or more I frames.

18. A method in accordance with claim 16, wherein the second portion of the data comprises less information than the first portion of the data.

19. A method in accordance with claim 16, further comprising:

encrypting the second portion of the data.

20. A method in accordance with claim 16, further comprising:

establishing a system for streaming the second portion of the data to client devices.

21. A method in accordance with claim 16, further comprising:

storing the first portion of the data on a physical media.

22. A method in accordance with claim 16, wherein the first portion of the data comprises unsecured data.
