Abstract: A device for retrieving media data includes one or more processors configured to retrieve media data from a first adaptation set including media data of a first type, present media data from the first adaptation set, in response to a request to switch to a second adaptation set including media data of the first type: retrieve media data from the second adaptation set including a switch point of the second adaptation set, and present media data from the second adaptation set after an actual playout time has met or exceeded a playout time for the switch point.

Abstract: In overview, the various embodiments provide methods implemented by a processor executing a DASH client on a receiver device for determining when, in view of a change in the receiver device's resources (e.g., bandwidth, battery power, etc.), to cancel or abandon downloading the current segment at the current representation and restart download of the current segment at a different representation to meet one or more performance objectives and/or optimizations related to the change in the receiver device's resources. In various embodiments, the receiver device processor may perform a cost-benefit analysis to determine whether switching representations during the ongoing download of the current segment will benefit the performance of the receiver device, and the receiver device processor may switch representations in response to determining that switching representations would improve the performance of the receiver device.

Abstract: A communication system enables a node to utilize multiple communication interfaces to connect to an overlay network. The use of multiple communication interfaces provides a redundant overlay network connection, thereby enabling a node to maintain connectivity or select a preferred connection to the overlay network, increasing efficiency or reducing costs in the overlay network. A network in which member nodes obtain services in the absence of server-based infrastructure is referred to as a “peer-to-peer overlay network” (or “overlay network” or simply “overlay”). Overlay networks consist of several nodes from hundreds, to thousands, joined together in a logical routing structure. Individual nodes often participate in routing and maintenance aspects of the overlay. Typically an overlay is formed through the enrollment and joining of all these nodes as defined by the overlay protocol. Nodes forming peer-to-peer overlay networks may communicate with each other over various network technologies.

Abstract: Methods and apparatus for adaptively scheduling a finger stabilization algorithm. A method is provided that includes comparing first and second finger determinations associated with a node, increasing a time interval between executions of a finger stabilization algorithm if differences between the finger determinations satisfy a first criteria, and decreasing the time interval between executions of the finger stabilization algorithm if differences between the finger determinations satisfy a second criteria.
