Abstract

A system and method for using a custom media library to secure digital media content on a computing system is disclosed. The method includes directly linking the custom media library with a copyright compliance mechanism (CCM)-enabled playback/recording application. In addition, the custom media library generates a new pathway distinct from a commonly used data pathway of the CCM-enabled playback/recording application and a media rendering subsystem of an operating system. Also, a CCM is alerted to monitor a plurality of media subsystems of the computing system. In so doing, a raw media file may be securely passed from the CCM-enabled playback/recording application via the custom media library and over the new pathway to a media subsystem of the operating system that is monitored by the CCM, such that the raw media file is rendered, playable and copyable in a secure environment.

Claims

1. A method for using a custom media library to secure digital media content on a computing system, said method comprising:

directly linking said custom media library with a copyright compliance mechanism (CCM)-enabled playback/recording/recording application;

utilizing said custom media library to generate a new pathway distinct from a commonly used data pathway of said CCM-enabled playback/recording application and a media rendering subsystem of an operating system;

alerting a CCM to monitor a plurality of media subsystems of said computing system; and

securely passing a raw media file from said CCM-enabled playback/recording application via said custom media library and over said new pathway to a media subsystem of said operating system that is monitored by said CCM, such that said raw media file continuously remains in a secure environment during rendering, playback and recording.

2. The method of claim 1 further comprising:

directly linking said custom media library with said CCM-enabled playback/recording application such that said custom media library is hard linked into said CCM-enabled playback/recording application.

3. The method of claim 1 further comprising:

utilizing said new pathway to bypass said media rendering subsystem of said operating system.

4. The method of claim 1 further comprising:

utilizing said custom media library to generate said new pathway at the user mode.

5. The method of claim 4 further comprising:

utilizing said new pathway to link said custom media library with a kernel mode said media subsystem of said operating system monitored by said CCM.

6. The method of claim 4 further comprising:

utilizing said new pathway to link said custom media library with a driver level said media subsystem of said operating system monitored by said CCM.

7. The method of claim 1 further comprising:

securely passing said raw media file from said media subsystem of said operating system that is monitored by said CCM to said media rendering subsystem such that a copyright of said raw media file is protected.

8. The method of claim 1 further comprising:

accessing a serial copy management system information for said digital media content; and

validating said serial copy management system information.

9. The method of claim 8 further comprising:

accessing copy and playback management information associated with said digital media content; and

utilizing said copy management information to determine if a secure copy and playback application is authorized to generate a copy of said digital media content.

10. A system for secure and controlled digital media content rendering comprising:

a media library directly linked with a copyright compliance mechanism (CCM)-enabled playback/recording application;

a new pathway generated by said custom media library at the user mode, said new pathway distinct from a commonly used data pathway of said CCM-enabled playback/recording application and a media rendering subsystem of an operating system;

an informing generator informing a CCM to monitor a plurality of media subsystems on a computing system, such that a raw media file is securely passed from said CCM-enabled playback/recording application via said custom media library and over said new pathway to a media subsystem of said operating system that is monitored by said CCM, such that said raw media file continuously remains in a secure environment during rendering, playback and recording.

11. The system of claim 10 wherein said new pathway initially bypasses said media rendering subsystem of said operating system and is only provided to said media rendering subsystem from within the secure CCM.

12. The system of claim 11, wherein utilizing said new pathway to link said custom media library with a kernel mode said media subsystem of said operating system or a driver level said media subsystem of said operating system monitored by said CCM.

13. The system of claim 10, further comprising:

a computer storage medium having instruction stored therein, said instructions when executed causing a computer system to perform secure and controlled copying and playback of a digital media content, said instructions comprising;

a source file receiver receiving a source file of said digital media content, said source file having (n) copy and (n) playback management information associated therewith;

a destination file generator generating a destination file based on said source file of said digital media content said destination file having (0) copy and (n) playback management information associated therewith;

a modified source file generator generating a modified source file based on said source file of said digital media content said modified source file having (n−

1) copy and (n) playback management information associated therewith; and

a validator validating said destination file and said modified source file based on said source file of said digital media content.

14. A computer readable medium having computer implementable instructions stored thereon, said instructions for causing a compliance mechanism to perform a method for using a custom media library to secure digital media content on a computing system, said method comprising:

directly linking said custom media library with a copyright compliance mechanism (CCM)-enabled playback/recording application;

utilizing said custom media library to generate a new pathway at the user mode, said new pathway distinct from a commonly used data pathway of said CCM-enabled playback/recording application and a media rendering subsystem of an operating system, said new pathway bypassing said media rendering subsystem of said operating system;

alerting a CCM to monitor a plurality of media subsystems of said computing system; and

securely passing a raw media file from said CCM-enabled playback/recording application via said custom media library and over said new pathway to a media subsystem of said operating system that is monitored by said CCM, such that said raw media file continuously remains in a secure environment during rendering, playback and recording.

15. The computer readable medium of claim 14 further comprising:

directly linking said custom media library with said CCM-enabled playback/recording application such that said custom media library is hard linked into said CCM-enabled playback/recording application.

16. The computer readable medium of claim 14 further comprising:

utilizing said new pathway to link said custom media library with a kernel mode said media subsystem of said operating system monitored by said CCM.

17. The computer readable medium of claim 14 further comprising:

utilizing said new pathway to link said custom media library with a driver level said media subsystem of said operating system monitored by said CCM.

18. The computer readable medium of claim 14 further comprising:

securely passing said raw media file from said media subsystem of said operating system that is monitored by said CCM to said media rendering subsystem such that a copyright of said raw media file is protected.

19. The computer readable medium of claim 14 further comprising:

accessing a serial copy management system information for said digital media content; and

validating said serial copy management system information.

20. The computer readable medium of claim 19 further comprising:

accessing copy and playback management information of said digital media content; and

utilizing said copy management information to determine if a secure copy and playback application is authorized to generate a copy of said digital media content.
