An autonomous computer based method and system is described for personalized production of videos such as team sport videos such as basketball videos from multi-sensored data under limited display resolution. Embodiments of the present invention relate to the selection of a view to display from among the multiple video streams captured by the camera network. Technical solutions are provided to provide perceptual comfort as well as an efficient integration of contextual information, which is implemented, for example, by smoothing generated viewpoint/camera sequences to alleviate flickering visual artefacts and discontinuous story-telling artefacts. A design and implementation of the viewpoint selection process is disclosed that has been verified by experiments, which shows that the method and system of the present invention efficiently distribute the processing load across cameras, and effectively selects viewpoints that cover the team action at hand while avoiding major perceptual artefacts.

A method is provided for efficiently processing messages staged for authentication in a security layer of a protocol stack in a wireless vehicle-to-vehicle communication system. The vehicle-to-vehicle communication system includes a host vehicle receiver for receiving messages transmitted by one or more remote vehicles. The host receiver is configured to authenticate received messages in a security layer of a protocol stack. A wireless message broadcast by a remote vehicle is received. The wireless message contains characteristic data of the remote vehicle. The characteristic data is analyzed for determining whether the wireless message is in compliance with a predetermined parameter of the host vehicle. The wireless message is discarded prior to a transfer of the wireless message to the security layer in response to a determination that the wireless message is not in compliance with the predetermined parameter of the host vehicle. Otherwise, the wireless message is transferred to the security layer.

A method and system directed to improve effectiveness and efficiency of cache and data management by differentiating data based on certain attributes associated with the data and reducing the bottleneck to storage. The data-aware cache differentiates and manages data using a state machine having certain states. The data-aware cache may use data pattern and traffic statistics to retain frequently used data in cache longer by transitioning it into Sticky or StickyDirty states. The data-aware cache may also use content or application related attributes to differentiate and retain certain data in cache longer. Further, the data-aware cache may provide cache status and statistics information to a data-aware data flow manager, thus assisting data-aware data flow manager to determine which data to cache and which data to pipe directly through, or to switch cache policies dynamically, thus avoiding some of the overhead associated with caches. The data-aware cache may also place clean and dirty data in separate states, enabling more efficient cache mirroring and flush, thus improve system reliability and performance.

A computerized document retrieval system has a file store holding a collection of documents, and indexer for constructing and updating at least one index from the contents of the documents, and a search engine for searching the index to retrieve documents from the file store. The indexer comprises three asynchronously executable processes: (a) a crawl process, which scans the file store to find documents requiring to be indexed, (b) an extract process, which accesses the documents requiring to be indexed and extracts indexing data from them, and (c) a build process, which uses the indexing data to construct or update the index.

Information is more efficiently distributed between master and slave information handling systems interfaced through a blocking network of switches by storing the information on switches within the blocking network and distributing the information from the switches. As an example, an application distribution module located on a leaf switch distributes an application, such as an operating system, to connected slave nodes so that the slave nodes do not have to retrieve the operating system from the master node through the blocking network. For instance, a PXE boot request from a slave node to the master node is intercepted at the leaf switch to allow the slave node to boot from an image of the operating system stored in local memory of the leaf switch.

A method, system and computer program product for an asynchronous interconnection between nodes of a clustered database management system (DBMS). Node timestamps are provided when each of the nodes in the cluster are started. Two or more communication conduits are established between the nodes. Each communication conduit between a local node and a remote node has an associated session identifier.
