摘要： A home domain building method and system that allow devices to join a home domain using smart cards. In the method, a master device reads device information from a smart card having a device ID and a device key as the device information of a guest device authenticated as a legal device and transmits a challenge request signal to the guest device, the guest device randomly generates a challenge value in response to the challenge request signal, the master device encrypts the challenge value using the device key of the guest device and transmits the encrypted challenge value to the guest device, the guest device decrypts the encrypted challenge value, and if the decrypted challenge value is the same as the challenge value generated in response to the challenge request signal, the guest device allows the master device to join the guest device in the home domain.

摘要： Provided is a contents sharing method between a mobile terminal and a local server. The contents sharing method between a client terminal storing metadata and a server terminal storing the metadata, the method comprising requesting the server terminal for a contents share service; and receiving information on contents corresponding to matching metadata as a result of comparing the metadata stored in the, client terminal and the metadata stored in the server terminal, thereby sharing contents desired by the user without the user's intervention. Also, the user can communicate desired contents information with people in a bus, subway, library, etc., which forms a social network, and produces a contents flow between mobile terminals, thereby creating a new business model such as contents resale, promotion, etc.

摘要： A scheduled recording method, which schedules recording of copy-protected content, is provided. The scheduled recording method involves determining whether copy control information of content of interest exists in a recording device storing various copy control information; if the copy control information does not exist in the recording device, newly receiving copy control information and then determining whether the copy control information exists among the newly received information; if the copy control information of the content exists in the recording device, determining whether the copy control information “copy never”; and if the copy control information of the content is “copy never”, transmitting an error message to a user indicating that the content of interest is not recordable to a user. Accordingly, it is possible to let a user know about whether content is recordable by defining a copy protection status variable and determining whether the content is recordable whenever new copy control information is received.
