A dataflow control apparatus extracts a device capable of providing data that satisfies requirements of an application by matching device-side metadata and app-side metadata. In the case where the extracted device is a virtual device that generates new data on the basis of data that is obtained from one or more original devices and outputs the generated new data as virtual data, the dataflow control apparatus transmits a first dataflow control command instructing transmission of data from the original device to the virtual device, and transmits a second dataflow control command instructing transmission of virtual data from the virtual device to the application.

A server facilitates sharing of otherwise idle placeshifting devices over the Internet or another network. The server maintains a list of placeshifting devices that are available to share content via the network. When a selection of shared content is received from a client device, an available placeshifting device that has access to the requested content is identified. The client device and the identified placeshifting device establish a placeshifting connection over the network in which the client device controls the identified placeshifting device to obtain the selected content.

摘要:
A node enables sharing data connectivity between a consumer device and a broker device, and receives from a first packet routing node a request for a consumer authorization certificate. The request includes a subscriber identity. Based on the subscriber identity authorizing the subscriber for sharing data connectivity; a consumer authorization certificate is generated using a private encryption key associated with the node. The consumer authorization certificate includes the subscriber identity of the subscriber. The consumer authorization certificate is returned to the first packet routing node. A request for a data connectivity service for the subscriber is received from a second packet routing node. The request includes a consumer agreement certificate and a broker identity. The consumer agreement certificate is signed using a private key associated with the subscriber and includes the subscriber identity. The consumer agreement certificate is valued. A confirmation message is sent to the second packet routing node.

The present invention relates to a client node(12, 70, 710, 720), a proxy node (14, 16, 200, 500, 10, 520),and methods therein, as well as a protocol and a computer program for enabling interception of request messages in connection-less protocols.A primary request addressed to a server node is intercepted (302, 402) by a proxy node creating(304, 404) a secondary request based on said request and forwards(304, 406) this secondary request towards the server node. The proxy node receives (306, 408) a secondary response, being a response to the secondary request, creates (308, 310, 410, 412, 414) a primary response based on the secondary response and forwards (312, 416) this primary response to the node from which the primary request was received.A response can thus be sent along the same path as a corresponding request was sent.

A method of service synchronization and sharing and multi-device control in a digital home comprises: A web page of a WEB server at the same time comprises multiple subservices corresponding to terminal devices of different types. When the WEB server is requested, relay devices located between a WEB server and the terminal devices divide the WEB server into subservices having a synchronization relationship, and push the subservices to respective terminal devices. The relay device at least comprises a browser and a WEB server module.
摘要:
A networked data processing apparatus includes a first communication interface (102) adapted for transmitting and receiving commands and/or status messages related to a plurality of remotely located network devices connected via the interface, and further includes a first data storage for non-volatile storage of raw data received from the remote network devices. A processing unit (105) of the apparatus is adapted for processing raw data retrieved from the first data storage (104) or received in real-time via the first communication interface (102). The processing unit (105) further transmits commands and data to the remote network devices in response to processing respective corresponding data. The apparatus further includes a second data storage (107) for non-volatile storage of data processing results and is adapted for maintaining a link between data stored in the second storage (107) and raw data stored in the first data storage (104). A second communication interface (106) receives and handles data access requests, data processing requests and/or commands, and provides data and/or data processing results in response to the requests.
