Abstract: In case that a main component and an auxiliary component to be presented in synchronization with the main one have to be presented through data transmission between both devices, the present invention issues an action for setting access location information (e.g., URL) of at least one auxiliary component to a media renderer, wherein the action is different from an action for setting access location information of a main component. As a different way, the present invention sets access location information of at least one auxiliary component to a media renderer through an action including access location information of an auxiliary component as well as access location information of a main component.

Abstract: The present invention is to ensure security of a local network, e.g., a home network from remote access while allowing remote access. In a method of the present invention, if a device on the local network is to be accessed remotely, user identifying information (and/or device identifying information) and connection information of a target device, that are accompanied by the access, are compared with information of registered allowance entries and whether to allow the access is determined based on the comparison result. According to the method, remote access to a device invoked by a user (and/or a remote device) whose remote access is not set to allowance is blocked while remote access invoked by a user (and/or a remote device) whose remote access is set to allowance is admitted.

Abstract: The present invention relates to a method for managing traffic transfer services on a network. One of the present methods determines priority reference ensuring to retrieve bandwidth greater than necessary bandwidth, if current available bandwidth is not sufficient for a new connection, and selected selects a combination of in-service connections whose priority is not higher than the determined priority reference such that the selected combination is able to return the necessary bandwidth and the number of connections in the selected combination is smallest as well. The connections pertaining to the selected combination are pre-empted to permit access of the new connection to the network.

Abstract: The present invention relates to a method for changing service quality of a content adaptively. In the present method, when allowance of access to a network is requested, whether transfer speed demanded by the request of access allowance can be provided is checked. If can not be provided, service quality of a connection being serviced is lowered. In the meantime, the present method monitors whether available bandwidth is generated, and upgrades service quality of a connection being serviced when available bandwidth is generated. The above operations can make a given network resource fully used.

Abstract: The present invention relates to a method for changing service quality of a content adaptively. When service quality updating action for a connection is received the present method invokes an action, used for requesting allowance of a new access to a network, to a device conducting traffic transfer services in order that service quality of the connection may be changed. The invoked action carries input arguments including traffic descriptor of the connection, carried by the service quality updating action, which a traffic handle for identifying the traffic descriptor uniquely has been allocated in.

Abstract: In case that a main component and an auxiliary component to be presented in synchronization with the main one have to be presented through data transmission between both devices, the present invention issues connection preparation actions to the both devices respectively for each of a main component and at least one auxiliary component associated with the main component, issues actions to set access location (e.g., URL) of each of the components (the main component and the at least one auxiliary component) to at least one of the both devices, and issues play actions for each component to at least one of the both devices.

Abstract: The present invention relates to method and apparatus for enabling to request querying and/or controlling operations remotely to a device on a home network via Internet. In a method in accordance with the present invention, a device search message is transmitted to a plurality of devices connected to a local network, and device information is created or modified based on whether there are responses to the message from the devices. Afterwards, when a device search message is received a responding message to the received message is transmitted for a device or devices contained in the device information. Whereby, possible communication errors occurred by long-time delay (caused by traveling across large-area network and local network) of a search message can be prevented.

Abstract: The present invention relates to technology for determining priority when an access to a network, e.g., UPnP-based home network is requested. An illustrative method according to the present invention sets one priority determinator among a plurality of determinators to default one, and asks the default priority determinator priority information on a connection for traffic when the connection is requested to be allowed.

Abstract: The present invention is to notify a user of whether content streaming service will be provided well or not by obtaining information for transfer of a content to be provided from outside before traffic of the content starts to be transferred. In a method according to the present invention, a CP (Control Point) or a gateway at a home network obtains requests an external server to provide information for transfer of a content stored in the external server, a TD (Traffic Descriptor) is constructed based on the provided information for transfer, and a QoS (Quality of Service) manager invokes an action requesting permission of traffic requiring a bandwidth specified by the TD to devices to be involved in traffic transferring of the content.

Abstract: The present invention relates to a method for managing traffic transfer services on a network. One of the present methods determines priority reference ensuring to retrieve bandwidth greater than necessary bandwidth, if current available bandwidth is not sufficient for a new connection, and selected selects a combination of in-service connections whose priority is not higher than the determined priority reference such that the selected combination is able to return the necessary bandwidth and the number of connections in the selected combination is smallest as well. The connections pertaining to the selected combination are pre-empted to permit access of the new connection to the network.

Abstract: The present invention relates to method and apparatus for enabling to request querying and/or controlling operations to a device on a home network via Internet. In a method in accordance with the present invention, a document of device list to show devices is made out in browser-interpretable format (or in remote UPnP-control point interpretable format) based on information provided from a plurality of devices connected to a home network, afterwards, a device searching message is transmitted periodically toward the plurality of devices and the document is modified based on responses to the message from the devices (or from a proxy on the home network) The modified document is provided for an external connection program, e.g., browser (or UPnP control point) to interpret/process, as a result, changed list of devices on the home network is displayed to a user.

Abstract: The present invention relates to method and apparatus for enabling remote query and control for a device on a home network. A starting control point or a gateway of home network in accordance with the present invention makes out a document of device list that shows a device in association with location information of a presentation page written in a device descriptor received from at least one of devices connected to a home network; and provides the document for a general browser to interpret/process in order that device list of the home network is displayed by the general browser when the general browser is executed.
