Abstract

Provided are a system renewability message providing method, a system renewability message using method and an apparatus thereof. The system renewability message providing method, includes: creating system renewability message container information including revocation list information for contents protection; and defining the system renewability message container information as an International Organization for Standardization (ISO) base media file format and distributing the system renewability message container information to a terminal.

Claims

1. A method for providing a system renewability message, comprising:

creating system renewability message container information including revocation list information for contents protection; and

defining the system renewability message container information as an International Organization for Standardization (ISO) base media file format and distributing the system renewability message container information to a terminal.

2. The method of claim 1, wherein the revocation list information includes security damaged-device identifier information or certificate information.

3. The method of claim 2, wherein use of the terminal for the contents is limited based on the device identifier information or the certificate information.

4. The method of claim 1, wherein the system renewability message container information is located in a highest level of a file.

5. The method of claim 1, wherein the system renewability message container information includes number information of system renewability message information included in the system renewability message container information and the system renewability message information.

6. The method of claim 5, wherein the system renewability message information includes identifier information on a system where the system renewability information is applied.

7. The method of claim 1, wherein the revocation list information includes:

identifier information on a revocation scheme and list information analyzed by the revocation scheme.

8. A method for using a system renewability message, comprising:

receiving system renewability message container information which includes revocation list information for contents protection and is defined as an International Organization for Standardization (ISO) base media file format; and

limiting access to contents based on the received system renewability message container information.

9. The method of claim 8, wherein the revocation list information includes security damaged-device identifier information or certificate information.

10. The method of claim 9, wherein use of the contents is limited based on the device identifier information or the certificate information.

11. The method of claim 8, wherein the system renewability message container information is located in a highest level of a file.

12. The method of claim 8, wherein the system renewability message container information includes number information of system renewability message information included in the system renewability message container information and the system renewability message information.

13. The method of claim 12, wherein the system renewability message information includes identifier information on a system where the system renewability information is applied.

14. The method of claim 8, wherein the revocation list information includes identifier information on a revocation scheme and list information analyzed by the revocation scheme.
