Abstract: The embodiments of the invention relate to application-layer multicasting, particularly to reduction of join/attachment latency of a node when joining a multicast group, by providing to a joining node a flat peer list and a preferred peer list which contains candidate node entries with recent available bandwidth information.

Abstract: For display of, at a user device, a region of interest within video images and associated applications. In a particular example embodiment, a streaming video source provides streaming data to a user device, with the streaming data being representative of a sequence of images, and each image including a plurality of individually decodable slices. At the user device and for a particular image and a corresponding subset region of the image, less than all of the plurality of individually decodable slices are displayed in response to a current input indicative of the subset region. Future input indicative of a revised subset region is then predicted in response to images in the image sequence that have yet to be displayed and to previously received input. In other embodiments, multicasting methods, systems or arrangements provide streaming video to one or more user devices.

Abstract: A variety of methods, systems, devices and configured storage devices are used in relation to peer-to-peer streaming system with a plurality of processing-circuit-peer nodes sharing streaming data by passing the streaming data from parent nodes to child nodes. According to one such system, computer-based nodes are configured and adapted to detect a departure of a first child peer node from the peer-to-peer streaming system. The first child peer node having been a child peer node of the parent peer node and the first child peer having provided data to one or more additional child peers. Responsive to the detected departure, a second child peer is selected to provide data to the one or more additional child peers. Data is provided to the second child peer to facilitate establishment of a connection between the selected child peer and the one or more additional child peers and the parent peer node.

Abstract: Systems, devices and methods for supporting live and time-shifted video streaming via distributed caching of portions of video streams shared in peer-to-peer portions of systems.

Abstract: Systems, devices and methods for supporting live and time-shifted video streaming via distributed search methods for registering and locating cached portions of video streams shared in peer-to-peer systems.
