Abstract: Disclosed is a UPnP AV device interworking method of a UPnP-based network system which allows UPnP AV devices located on different networks to interwork with each other. Applications of the UPnP devices are widely expanded at a low cost by transforming a private address to a public address by URI address transformation between the UPnP AV devices located on a home network and a common internet.

Abstract: Disclosed are a UPnP-based media contents reproducing system and a method thereof capable of fast and consecutively reproducing media contents reproduced by a first control point in another space by a second control point by informing state information of the media contents reproduced by the first control point to the second control point. The media contents reproducing system comprises a media server; a media renderer; and a first control point for controlling the media server and the media renderer, and transmitting rendering state information of the media renderer to the second control point.

Abstract: Disclosed is a method for automatically setting a network so that UPnP devices connected to a network composed of different IP segments can be communicated one another. The method comprises: receiving an event message transmitted from a device connected to a network; requesting a routing table to all devices connected to the network except said device; and adding an IP address of said device to the routing tables inside all the devices.

Abstract: The present invention discloses a method for setting media streaming parameters on a UPnP-based network which can improve quality of media. The method for setting the media streaming parameters on the UPnP-based network can improve media playing quality and efficiently use resources of each device, by allowing an AV control point to monitor states of UPnP devices regardless of a media transfer protocol, transmit traffic transfer parameters for optimum quality of media to each UPnP device, and automatically set optimum parameters or make each UPnP device set the optimum parameters upon the user's request.

Abstract: An accessing method for providing access to a device connected to a network comprises, in a first application, authenticating a second application. The method also comprises, in the second application, requesting an action on a secure service provided by the device, based on the authenticating of the second application in the first application. The requesting an action on a secure service provided by the device may be performed after the first application has assigned an access permission to the secure service provided by the device to the second application. The action on a secure service provided by the device may include reading a password created in the device. The device may be a server device containing media files. The method may further comprise expiring the password after a first use.
