Apparatus and method for reporting operation state of digital rights management
First Claim
1. An apparatus for reporting an operation state of digital rights management (DRM) of a control device to a control point in a home network formed with the at least one control device and the control point, the apparatus comprising:
- a processor;
a DRM module which performs DRM;
a state variable generation unit which receives DRM operation state information indicating the state of a DRM process currently operating, from the DRM module, and generates DRM state variables based on the received DRM state information; and
a universal plug and play (uPnP) module which, by using a uPnP protocol, transmits the state variables generated by the state variable generation unit to the control point,wherein if the DRM state information indicates that authentication by the DRM module is successful, the state variable generation unit causes an authenticating state variable, which indicates that an authentication operation by the DRM module is performed, to change to a normal-operation state variable which indicates that the DRM module is normally operating, and if the DRM state information indicates that the authentication by the DRM module has failed, the state variable generation unit causes the authenticating state variable to change to an authentication-failed state variable which indicates that a result of the authentication by the DRM module is a failure.

Abstract
A method and apparatus for reporting the operation state of digital rights management are provided. In a home network formed with control devices and a control point, the apparatus for reporting the operation state of digital rights management of the control device to the control point includes: a digital rights management (DRM) module which performs digital rights management; a state variable generation unit which receives DRM operation state information indicating the state of a DRM process currently operating, from the DRM module, and based on the received DRM state information, generates DRM state variables; and a universal plug and play (uPnP) module which by using a uPnP protocol, transmits the generated state variables to the control point.

10. An apparatus for reporting an operation state of digital rights management (DRM) of a control device to a control point in a home network formed with the at least one control device and the control point, the apparatus comprising:
-
a processor; a DRM module which performs DRM; a state variable generation unit which receives DRM operation state information indicating the state of a DRM process currently operating, from the DRM module, and generates DRM state variables based on the received DRM state information; and a universal plug and play (uPnP) module which, by using a uPnP protocol, transmits the state variables generated by the state variable generation unit to the control point, wherein when the DRM state information indicates an authentication finishing condition of the at least one control device, the state variable generation unit causes a normal-operation state variable, which indicates that the DRM module is normally operating, to change to a not-authenticated state variable which indicates that the at least one control device including the DRM module is turned on.

11. An apparatus for reporting an operation state of digital rights management (DRM) of a control device to a control point in a home network formed with the at least one control device and the control point, the apparatus comprising:
-
a processor; a DRM module which performs DRM; a state variable generation unit which receives DRM operation state information indicating the state of a DRM process currently operating, from the DRM module, and generates DRM state variables based on the received DRM state information; and a universal plug and play (uPnP) module which, by using a uPnP protocol, transmits the state variables generated by the state variable generation unit to the control point, wherein the state variable generation unit further generates; a key-processing state variable which indicates that a key processing operation by the DRM module is performed; and a key-processing-failure state variable which indicates that the key-processing operation by the DRM module is a failure. - View Dependent Claims (12, 13, 14)

15. A method for reporting the operation state of digital rights management (DRM) of a control device to a control point in a home network formed with the control device and the control point, the method comprising:
-
performing, by a DRM module, DRM; generating DRM state information determining a current DRM operation currently operating; generating, by the control device, a DRM state variable based on the DRM state information; and transmitting the generated DRM state variable to the control point by using a universal plug and play (uPnP) protocol, wherein if the DRM state information indicates that the authentication by the DRM module is successful, the generating the DRM state variable comprises causing an authenticating state variable, which indicates that an authentication operation by the DRM module is performed, to change to a normal-operation state variable which indicates that the DRM module is normally operating, and if the DRM state information indicates that the authentication by the DRM module has failed, the generating the DRM state variable comprises causing the authenticating state variable to change to a authentication-failed state variable which indicates that a result of the authentication by the DRM module has failed. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
