20080263173 | Method for Transmitting Data in a Network of Distributed Stations, and Network Station - The invention relates to the technical field of home networks. A home network based on the present UPnP standard (Universal Plug and Play) allows data to be interchanged between network subscriber stations. A UPnP standard may have one or more control point devices. To allow profile information such as user profile or network profile to be interchanged, the invention proposes providing a control point device firstly with an expanded device ascertainment service which can be used to find the other control point devices in the network and also with one or more additionally implemented profile services which allow the other control point devices in the network to be notified about change to profile information on a control point device. | 10-23-2008 |
20090119766 | Method for Remotely Accessing a Local Area Network, and Switching Node for Carrying Out the Method - The invention relates to the technical field of data transmission in a network of distributed stations. One problem particularly with a UPnP-based home network is that although the network-internal communication is based on the IP protocol, the allocated IP addresses are valid only locally and they therefore cannot be accessed via the Internet. This is the starting point of the invention, which proposes that remote access to the network have the network's switching node provide address conversion which is effected using an internally managed table about the devices which are present in the network and their IP addresses. For the remote access, the globally valid IP address of the switching node is used, with an additional information item being additionally provided in the HTTP Get remote access and allowing the address conversion. A suitable additional information item is the converted local IP address of the network station which is to be addressed, in particular. The response to the remote access involves the inverse address conversion, so that the references back to the local area network again contain the globally valid address of the switching node plus the additional information item. | 05-07-2009 |
20090240848 | Method and Device for the Transfer of a Data Flow a Data Source to a Data Sink - In the transfer of AV data flows, especially in a network environment, a delayed transition from one operating mode to the other operating mode will be possible when changing the operating mode from e.g. normal replay to fast forward search. This is due to the fact that—in the transfer from data source to data sink different buffer memory stages must be passed before the transferred data finally come to decoding. When the request for changing the operating mode comes, the data already present in the buffer memories must first be processed before the actually requested new data come to be decoded. For the solution of the problem described, it is suggested according to the invention that—after the request of changing the operating mode—the undesirable data in the buffer memories are quickly eliminated through suitable measures so that the desired data can then be decoded faster. To do that, an identifier for the new operating mode is inserted in the data flow on the part of the data source device. The decoder driver of the decoder in the data sink device will search for the inserted identifier in the data flow and reject all data packets which are not combined with this identifier. Thus, the buffer memory stages are discharged fast and a smooth transition with the change of operating mode will be realized. | 09-24-2009 |
20090287812 | Network Connection Switching Unit and Network Station - The invention relates to the field of data transmission in a network of distributed stations. One problem, particularly in a UPnP based network, is that the UPNP devices need to be constantly switched on in order to be available in the network. The invention intervenes at this point and describes ways in which unused network stations can be switched off but continue to be identified as devices in the network. If a device which is switched off is needed, it is automatically switched on. This allows a considerable power saving to be achieved in the network. The invention provides for a network connection switching unit to contain “communication maintenance means” which maintain the communication for an inactivated network station at least to a restricted extent instead of the inactivated network station. A network station matched thereto is also proposed. | 11-19-2009 |

20100122045 | Method for processing data using triple buffering - The present invention relates to a method for processing data. A data block to be processed is written to a memory area in a first interval of time. The data block is processed in the same memory area (A, B, C) in a second interval of time. The processed data block is returned from the same memory area in a third interval of time. | 05-13-2010 |
20140189106 | Method for managing logical connections in a network of distributed stations, as well as a network station - The invention relates to the technical field of domestic networks. A domestic network based on the present UPnp-Standard allows AV connections to be set up between two network subscriber stations—Network connections such as these are set up and managed under the control of a network station which is in the form of a control point. In this case, the UPnP-Standard allows the network station which is the form of a control point to log off the network after setting up an AV connection, and thus to be inactive while the AV connection that has been set up is in existence. This results in the problem that an AV connection which has been set up unnecessarily remains in existence even after the desired AV data stream has been transmitted, so that further connection requests for such stations must be answered with a rejection. The invention solves this problem in that it provides additional monitoring means in the network subscriber stations which determine whether the connection has remained unused for a specific time. If yes, a signaling request is sent to all the network subscriber stations. If the connection partner station does not then respond, the connection which has been set up can likewise be added autonomously by the requesting station. | 07-03-2014 |
20140346234 | METHOD, APPARATUS AND STORAGE MEDIUM FOR TWO-DIMENSIONAL DATA STORAGE - A method and an apparatus for reading a data pattern from or writing a data pattern to a storage medium are described. During reading a pattern retrieval stage retrieves a test pattern and the data pattern from the storage medium. A decoder, which is trained with pattern elements of the retrieved test pattern by a training stage, decodes the retrieved data pattern by performing a comparison between topologies of the retrieved data pattern and representative patterns derived from the test pattern during training of the decoder. | 11-27-2014 |
