Abstract: PURPOSE: A method for sharing digital contents in theater of digital cinema contents of which DRM(Digital Rights Management) is applied, is provided to enable the screening device to share the KDM(Key Delivery Message) by setting the multiple screening device in the theater as the domain. CONSTITUTION: When the KDM transfer request is received from a contents server, the KDM or mastering server authenticates the general KDM(S100). When the general KDM is authenticated, the server cancels the encoding(S200). The server decides the domain right request(S300). The server adds the domain authority to the encoded KDM and inputs the domain certificate. The server issues the domain KDM of which the domain certificate is inputted to the screening server.

Abstract: PURPOSE: A navigation device and a path guide method thereof are provided to guide an accurate path since concentration on an event can be caused through the automatic expanding of an electronic map and building information on destination is added. CONSTITUTION: A path guide method of a navigation device is as follows. If the remaining distance from the current position of the navigation device to destination is within an established distance, the scale of the electronic map becomes larger than an initially established scale(S280). If the remaining distance is within the established distance, a direction to guide to the destination and a building on the direction to guide are indicated on the electronic map in a state the established scale of the electronic map is maintained. If not, the scale of the electronic map becomes larger than the initially established scale whenever an event occurs(S250).

Abstract: PURPOSE: A trusted platform module and a data management method are provided to use environment set data relevant to the trusted platform module, thereby preventing an application data operation from influencing another application program operation. CONSTITUTION: A TPM(Trusted Platform Module) receives a first command from a TSS(Trusted Software Module)(S100). If the first command uses environmental setting data, a context management unit determines whether to store environmental setting data corresponding to a first context value in a plurality of data storage units(S110,S130). A command processor processes the first command based on the first environment setting data and an integrity measurement value(S140). If data is changed, the command processor stores the changed first environmental setting data(S160,S170).
