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 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.

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.

17. 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 DRM;
generating DRM state information determining a current DRM operation currently operating;
generating 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. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
