Abstract: A conditional access system and a synchronizing method thereof are provided to minimize the disconnection phenomenon by providing a conditional access software of the next version to a terminal in advance a next version software while receiving a broadcasting signal in the synchronization of a terminal. A head end creates program designation information by which a conditional access software for a specific channel broadcasting can be downloaded, then is transmitted to a terminal(S510). A terminal judges whether or not the received program designation information is a program which requires the change of the version of the conditional access software(S520). If so, the terminal downloads the changed conditional access software according to the program designation information(S530). A broadcasting program is available on service by executing the conditional access software based on the point when the version of the software is changed(S540).

Abstract: A system for providing the continuity of a communication service on a home network and a method therefor are provided to enable an SIP(Session Initiation Protocol) home server to register VoIP/video call terminals inside home as the same group and transmit a call request signal to all VoIP/video call terminals registered as the same group when a call connection is requested from the outside, thereby enabling a user to receive the communication service through a VoIP/video call terminal positioned closely wherever the user is inside the home. A method for providing the continuity of a communication service on a home network comprises the following steps of: registering VoIP(Voice over Internet Protocol)/video call terminals inside home in the same group(S105); transmitting a call request message to the VoIP/video call terminals inside the home of the same group if a call request message is received from the outside(S120); communicating with a first VoIP/video call terminal which transmits a call connection response message if the call connection response message is received from one of the VoIP/video call terminals inside the home in response to the call request message(S150); receiving the location information of a first user which communicates with the first VoIP/video terminal while the call is connected to the first VoIP/video terminal(S260); waiting for the reception of the location information of the first user when a user location verification unavailable message instead of the first user location information is received; and switching the call connection through a second VoIP/video terminal installed at a location corresponding to second user location information if the second user location information different from the first user location information is received in the standby status.

Abstract: A remote controller key value allocation method for individual services provided from a TV portal service is provided to generate profiles for remote controller key values by downloading a program of an individual service selected by a user while the remote key values for each service can be allocated by using the profiles, thus a high-capacity memory space is unnecessary for previously storing the profile information of remote controller key value. A set top box delivers service selection information selected by a user from a service list to a TV portal server(S101). The set top box downloads an application for receiving a service selected by the TV portal server(S102). The set top box generates remote controller key value profile(S103). The set top box interprets the key value profiles included in the application, and allocates the remote controller key value profiles to remote controller operation functions(S104). If study for remote controller key values is successful(S105), the set top box executes a service by performing short-range wireless communication with a remote controller based on the remote controller key value profiles and a service key-map used for the study(S106).

Abstract: An SMMD(Single Media Multi Devices)-based ubiquitous home media service device and a method thereof, and a home medium service system and method using the same are provided to enable surrounding devices having various functions for providing a realistic media service to a user through ne-media by generating a ne-media, inputting realistic reproduction information fit for personal propensity of the user and context of the device to the ne-media, and transmitting the ne media to the devices. A database(300) stores sensor information, a device profile, a user profile, and the ne-media. A user interface(310) receives the ne-media by requesting the ne-media to an external ne-media providing server. A ne-media processing manager(320) separates the received ne-media into neo-data, the media comprising audio, video, and text, and sync/control and ID information of each device. An ne-media reproduction manager(330) plays the separated media. A device synch/control manager(340) generates a device group to be linked by collecting information of the surrounding devices, generates a synch signal between the media and the device by using the separated sync information, and records to synch signal to the ne-media. A network manager(350) transmits the ne-media received from the device synch/control manager to the surrounding devices.
