Abstract

A method of preventing unauthorized recording of electronic media is described. The method is comprised of activating a compliance mechanism in response to receiving media content by a client system. The compliance mechanism is coupled to the client system. The media content presentation application is operable and coupled to the compliance mechanism. The method is further comprised of controlling a data output path of the client computer with the compliance mechanism. The method is further comprised of directing the media content via the data output path to a custom media device for selectively restricting output of the media content. The custom media device is coupled to the compliance mechanism and to the media content presentation application. The method is further comprised of preventing a recording application coupled to the client computer system from recording the media content file when recording violates usage restriction applicable to the media content.

Claims

1. A method of preventing unauthorized recording of electronic media comprising:

activating a compliance mechanism in response to receiving media content by a client system, said compliance mechanism coupled to said client system, said client system having a media content presentation application operable thereon and coupled to said compliance mechanism;

controlling a data output path of said client system with said compliance mechanism by diverting a commonly used data pathway of said media player application to a controlled data pathway monitored by said compliance mechanism; and

directing said media content to a custom media device coupled to said compliance mechanism via said data output path, for selectively restricting output of said media content.

2. The method as recited in claim 1 further comprising preventing a recording application coupled to said client system from recording said media content when said recording violates usage restriction applicable to said media content.

3. The method as recited in claim 1 further comprising allowing a recording application coupled to said client system to record said media content when said recording complies with usage restrictions applicable to said media content.

4. The method as recited in claim 1 further comprising restricting said client system to have said custom media device implemented as a default media device.

5. The method as recited in claim 1 further comprising authorizing said client system to receive said media content.

6. The method as recited in claim 1 further comprising accessing an indicator associated with said media content for indicating to said compliance mechanism a usage restriction applicable to said media content.

7. The method as recited in claim 1 wherein said custom media device is an emulation of a custom media driver.

8. The method as recited in claim 1 further comprising altering said compliance mechanism in response to a change in said usage restriction, said usage restriction comprising a copyright restriction or licensing agreement applicable to said media content.

9. The method as recited in claim 1 wherein said media content is received from a source coupled to said client system, said source from the group consisting of:

a network, an electronic media device, a media storage device, a media storage device inserted in a media device player, a media player application, and a media recorder application.

10. A computer readable medium having computer implementable instructions embodied therein, said instructions for causing a client system to perform a method of restricting recording of media content, said method comprising:

animating a compliance mechanism coupled to said client system, said animating in response to said client system receiving media content, said client system having a media content presentation application coupled thereto and operable with said compliance mechanism;

managing an output path of said client system with said compliance mechanism by diverting a commonly used data pathway of said media player application to a controlled data pathway monitored by said compliance mechanism; and

governing said media content via said output path to a custom media device for selectively restricting output of said media content, said compliance mechanism utilized to stop or disrupt the playing of said media content file at said controlled data pathway when said playing of said media file content is outside of said usage restriction applicable to said media file.

11. The computer readable medium of claim 10 wherein said instructions cause said client system to perform said method further comprising:

authorizing said client system to receive said media content.

12. The computer readable medium of claim 10 wherein said instructions cause said client system to perform said method further comprising:

allowing a recording application coupled to said client system to record said media content file when said recording complies with a usage restriction applicable to said media content.

13. The computer readable medium of claim 10 wherein said instructions cause said client system to perform said method further comprising:

preventing a recording application coupled to said client computer from recording said media content when said recording violates a usage restriction applicable to said media content.

14. The computer readable medium of claim 10 wherein said custom media device is selected as a default media device.

15. The computer readable medium of claim 10 wherein said instructions cause said client system to perform said method further comprising:

accessing an indicator corresponding to said media content for indicating to said compliance mechanism a usage restriction applicable to said media content.

16. The computer readable medium of claim 10 wherein said custom media device is an emulation of a custom media driver.

17. The computer readable medium of claim 10 wherein said instructions cause said client computer system to perform said method further comprising:

altering said compliance mechanism is response to changes in said usage restriction, said usage restriction a copyright restriction or licensing agreement applicable to said media content.

18. The computer readable medium of claim 10 wherein said media content is from a source coupled with said client system, wherein said source is from the group consisting of:

a network, an electronic media device, a media storage device, a media storage device inserted in a media device player, a media player application, and a media recorder application.

19. A system of preventing unauthorized recording of electronic media comprising:

means for activating a compliance mechanism to control a data output path of a client system, said activating in response to said client system receiving media content, said

compliance mechanism coupled to said client system and operable in conjunction with a media

content presentation application coupled to said client system and operable thereon; and

means for directing said media content to a custom media device via said data output path controlled by said compliance mechanism, for selectively restricting output of said media content by diverting a commonly used data pathway of said media player application to a controlled data pathway monitored by said compliance mechanism, said compliance mechanism utilized to stop or disrupt the playing of said media content file at said controlled data pathway when said playing of said media file content is outside of said usage restriction applicable to said media file.

20. The system as recited in claim 19 further comprising:

means for allowing said media content to be recorded when said recording complies with usage restrictions applicable to said media content.

21. The system as recited in claim 19 further comprising:

means for preventing recording of said media content when said recording violates usage restriction applicable to said media content.

22. The system as recited in claim 19 further comprising:

means for restricting said client system to have said custom media device as a default media device.
