METHOD FOR MANAGING DIGITAL RIGHTS ON WIRED/WIRELESS ENVIRONMENT USING SERVER INFORMATION PARAMETER

摘要

A method for managing digital rights in a wired/wireless environment by using a service information parameter is provided to process an error in both ends of a device and an RI(Right Issuer) when the error occurring in processing a server information parameter during a registration stage of a DRM(Digital Rights Management) solution. A device wanting registration transmits a first message including basic information of the device to an RI(S100). The RI receiving the first message transmits a second message including the basic information of the RI to the device(S102). The device transmits a third message for requesting the registration to the RI(S104). The RI registers the device and transmits a fourth message including registration result information to the device(S106). The fourth message includes state information for representing whether or not a server information parameter included in the second and third message is changed. The device displays an error message, terminates connection with the RI, and stops a right object acquisition protocol when the fourth message setting the state information representing change of the server information parameter is received.
