A home system is provided. In a method of executing an application, information for executing the application is received from a device when accessing of the device is sensed, and the application is executed based on the received information. Accordingly, when a user merely brings a wireless guest device near to or in contact with an access point or a wired home device, it is possible to allow the wireless guest device to simultaneously automatically set an optimum security environment for a wireless network and execute an application that the user desires.

Method and apparatus for executing an application automatically according to the approach of wireless device

Provided is a mode-based access control method that includes: making a security mode list which indicates security setting states of devices existing in a home network; setting a specific security mode selected from the modes on the security mode list; and making the devices perform functions thereof in the specific security mode. Also, provided is a mode-based access control device includes: an authentication unit which checks information on a user and authenticates the user; a mode configuration unit which makes a security mode list indicating the security setting state of devices forming a home network; a mode setting unit which sets a specific security mode selected from modes on the security mode list; and an operating unit which causes the devices to perform functions thereof in the specific security mode.

Mode-based access control method and device

Provided is a method and system for synchronizing a plurality of content directory service (CDS) devices in a home network environment. The method of synchronizing the plurality of CDS devices of a home network, which includes the plurality of CDS devices and a control point (CP), comprises (a) requesting a first CDS device among the plurality of CDS devices to start synchronization using the CP; (b) performing the synchronization with a second CDS device among the plurality of CDS devices using the first CDS device; (c) selecting a third CDS device from the plurality of CDS devices and requesting the third CDS device to start synchronization with the first CDS device or the second CDS device using the CP; and (d) performing the synchronization with the first CDS device or the second CDS device using the third CDS device.

Method of synchronizing a plurality of content directory device (CDS) devices, CDS device, and system

Provided is a method of synchronizing content directory service (CDS) objects of a universal plug and play (UPnP) media servers. The UPnP media servers manage information on synchronization objects and synchronization policy information, which reduces the role of a control point (CP) in performing synchronization, so that the synchronization speed is increased.

Method and apparatus for synchronizing content directory service objects of universal plug and play media servers

A method of processing an action executes an action requested by a control point for controlling a controlled device through a network, stores a result of executing the action as a pending result of the action when a network connection between the controlled device and the control point is terminated, and transmits the stored pending result of the action to the control point when the network connection between the controlled device and the control point is resumed.

Method of processing action, method of controlling controlled device, controlled device, and control point

Provided is a remote user interface (RUI). An RUI server inserts a newly defined object to a user interface (UI) page so as to manage control ownership of an application, and a RUI client controls an application of the RUI server after obtaining control ownership of the corresponding application by using the newly defined object. Accordingly, RUI clients can control the application of the RUI server without conflict, even when a separate plug-in program is not installed in the RUI clients.

Method and apparatus for managing control ownership for application of remote user interface server

A method and apparatus for sharing secret information between devices in a home network are provided. In the method and apparatus, home network devices receive a password (credential) input by a user and encrypt secret information based on the credential by using keys generated according to a predetermined identity-based encryption (IBE) scheme. Accordingly, it is possible to securely share the secret information between home network devices without any certificate authority or certificate.

Method of and apparatus for sharing secret information between device in home network

A wireless universal serial bus (WUSB) security is provided. A method of providing a session key to be used during a session between a host and a device creates the session key based on a seed key stored in a region that is not allowed by the device; and provides the session key to the device. Therefore, a user does not need to distribute information necessary for creating the session key (i.e., a connection context) to a guest device.

Method and apparatus for providing session key for WUSB security and method and apparatus for obtaining the session key

An apparatus, system and method for executing discovery in a network are provided. The system for executing discovery in a network is configured with a SyncML server and a SyncML client, and includes a SyncML server that transmits a multicast search message to the SyncML client in order to search for a SyncML client that exists in a network, and executes a data synchronization with the found SyncML client, and a SyncML client that transmits a notify-alive message to the SyncML server in order to notify that the SyncML client exists in a network, and executes a synchronization with the SyncML server.

Apparatus, system and method for executing discovery in network

A universal plug and play (UPnP) network is provided. In the UPnP network, a QoS policy holder of a UPnP QoS architecture manages information on QoS modes that are previously set, and a QoS manager controls QoS devices by importing traffic policies for a predetermined QoS mode from the QoS policy holder. Accordingly, a user can suitably control traffic items in the network only by selecting a desirable QoS mode according to situations.

Method and apparatus for controlling quality of service in universal plug and play network

A method and apparatus for synchronizing contents of devices in a home network are provided. The apparatus includes a determination unit which determines whether a first device and a second device support a common synchronization protocol. A synchronization request unit then requests at least one device to synchronize the contents using the common synchronization protocol determined by the determination unit.

Method and apparatus for synchronizing contents of home network devices

A remote control apparatus and method are provided. The remote control apparatus includes a user interface (UI) server which transmits a UI having a multimedia data format, and a UI client which displays the UI, receives a user command and controls the UI server according to the received user command. The remote control method includes enabling a UI server to transmit a UI having a multimedia data format to a UI client, enabling the UI client to display the UI, and enabling the UI client to control the UI server by transmitting a user command received through the UI to the UI server.

Remote control apparatus and method

An apparatus and method for controlling a dispersion recording and playback of a moving picture are provided. The apparatus which controls a dispersion record of a moving picture includes, a recording unit that generates a record schedule when a predetermined moving picture is reserved-recorded, generates a reserved-recording-object when it is a reserved-recording time, and dispersedly records the moving picture in another storage device if an error occurs due to insufficient storage space when the moving picture is recorded; a recording-device-selecting unit that selects a recording device based on the preferences of storage devices before the moving picture is reserved-recorded, and a CDS-managing unit that manages recording information of the recorded moving picture, information of moving picture that has been recorded and the recording device.
