摘要:
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.

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.

Provided are a method and apparatus for managing a station by providing an encrypted key to the station in a wireless network under a Wi-Fi Protected Pre-Shared Key (WPA-PSK) environment. In the method, a registrar determines whether a new station is a guest station, based on user input. If the new station is a guest station, the registrar includes a session key (and not a shared key) into an M8 message according to a Wi-Fi Alliance (WFA) Simple Config protocol and transmits the M8 message to the station. Accordingly, it is possible to permit a guest station to temporarily access the network without a user's management of information regarding the guest station.

Provided are a network system and method for profiling a remote user interface (RUI), and more particularly, a network system and method for performing optimal RUI profile matching between an RUI client and an RUI server in order for optimal service adaptation for various contents based on composite capabilities/preference profiles (CC/PP).

Provided are a method and apparatus for generating a mashup graph. The method includes receiving a set of services and collecting application programmable interfaces (APIs) of the services, and generating a mashup graph by using the collected APIs according to information regarding connections between the APIs and weights between the APIs. Thus, a mashup graph having a simple form in which a user's preference can be reflected can be generated, instead of a complicated connection matrix.

A digital rights management (DRM) method and apparatus are provided. The DRM method includes generating a rights object request message for requesting a rights object corresponding to content stored in a media player and transmitting the rights object request message; receiving a rights object response message corresponding to the rights object request message from a media server which receives the rights object request message; and obtaining a rights object using the rights object response message.

Provided is a method for synchronizing contents included in devices in a Universal Plug and Play (UPnP) network. A control point device, which contains local content but cannot provide a content directory service, converts information regarding content objects of the control point device into Digital Item Description Language Lite (DIDL-Lite) format, and manages a mapping table, thereby performing synchronization with a device such as a UPnP media server providing a content directory service, without loading a separate protocol stack.
摘要:
A method of synchronizing a plurality of content-directory service (CDS) devices is provided. The method includes retrieving and discovering N CDS devices in a home network by a control point (CP), transmitting a StartSync message that requests the start of synchronization to a certain CDS device of the N CDS devices by the CP, forwarding a StartPeerSync message that informs remaining N-1 CDS devices of the fact that synchronization will be started by the CDS device that has received the StartSync message, and synchronizing each of the N CDS devices with the remaining N-1 CDS devices, in a home network that includes N CDS devices that provide metadata of multimedia content existing in the home network, and the CP that receives metadata from the N CDS devices and requests the media renderer to replay the multimedia data.
