摘要:
A method and apparatus for preventing duplicate saving of a resource between universal plug and play (UPnP) devices, which provide content directory service during content synchronization, are provided. The method includes receiving a change log including metadata about a changed resource from a UPnP device of a transmitter, determining whether the changed resource is a duplicate based on the received change log, and receiving and saving the changed resource according to a designated saving path based on a result of the determination.

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.

A method for controlling functions of a Management Device (MD) included in a home network is provided. The method for controlling the functions of the MD by a Control Device (CD) in a home network system including the CD for controlling functions of an Electronic Device (ED) connected to a home network and the MD, the functions of which are managed by the CD, includes diagnosing at least one function performed by the MD; identifying information necessary to control the at least one function; and transmitting, to the MD, control information for controlling the at least one function, in consideration of the information necessary to control the at least one function.
摘要:
A method, system and apparatus are provided for storing session information in a home network of an UPnP telephony service. The method is performed at a Telephony Server (TS). The method receives a request from a Telephony Control Point (TCP) to store session information while the session is in progress. The session information includes a session status and session related media. The method then divides the session information into meta information and session control information. Thereafter, the method stores the session information in a memory of the TS.

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.
摘要:
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.
摘要:
Method and application server for providing an asynchronous error notification from an application server to an application server controller in a network is provided. The method at the application server includes generating an error message when an error occurs at/during Open Service Gateway initiative (OSGi) framework runtime. The method also includes converting the error message as a Universal Plug and Play (UPnP) event. Moreover, the method includes providing the UPnP event comprising error information to the application server controller. The application server includes a receiver configured to receive a command from an application server controller to install an application in an Open Service Gateway initiative (OSGi) framework available at the application server. The application server also includes a processor configured to generate an error message when an error occurs during installation of the application in the framework and convert the error message as a Universal Plug and Play (UPnP) event. Moreover, the application server includes a transmitter configured to provide the UPnP event comprising the error information to the application server controller.
摘要:
A system and method for setting up security of a controlled device by a control point in a home network are provided, in which authority to perform a function intended by a user is acquired through authentication between the control point and the controlled device, a security channel is created for performing the function, and a credential setting used by the user is synchronized among controlled devices in the home network.
摘要:
An apparatus and method are provided for allowing UPnP devices to exchange power mode information with one another in a unified home network. The method of relaying a message in a unified network including at least first and second networks, the method includes receiving information regarding a power mode of a communication device connected to the first network from the communication device, generating a message indicating the power mode of the communication device based on the received information, and transmitting the message to the second network so that communication devices connected to the second network recognize the power mode of the communication device connected to the first network. Accordingly, even if a UPnP device in the power save mode cannot receive or transmit messages, another UPnP device can determine whether the UPnP device is connected to a network. If a new UPnP device generates an IP address according to an automatic IP mechanism, it is possible to prevent IP collision caused by a UPnP device that is connected to an IP network but operating in the power save mode.

Disclosed herein is a flat uniform transmission line having an electromagnetic shielding function. The flat uniform transmission line includes a strip transmission line, an insulating layer, and electromagnetic shielding layers. The strip transmission line is formed on a dielectric layer made of functional polymer material, and includes a plurality of strip lines. The plurality of strip lines are configured to be a ground line, or to transmit signals. The insulating layer is formed on the strip transmission line. The electromagnetic shielding layers are respectively formed on the insulating layer and beneath the strip transmission line.
