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.
