Abstract: A system for synchronized data playback comprising at least one offset calculation device; and a plurality of clients; wherein the plurality of clients are each synchronized to a shared reference timeframe, each of the plurality of clients is configured to receive a common set of timestamped data frames, the offset calculation device is configured to determine a synchronized playback time for each of the common set of timestamped data frames with respect to the shared reference timeframe; and each of the plurality of clients is configured to playback each of the common set of timestamped data frames at the respective determined playback time.

Abstract: Systems and methods for data scheduling and queuing. A data network node is configured to transmit data in a store-and-forward fashion. The data network node includes a delay and validity determination module that determines and assigns a validity value to each data packet incoming via an input port based on a time stamp of the data packet, a current time value, an expected delay on a route of the data packet to its destination, and a packet urgency value. A scheduling module and a queue managing module execute their functions based on the validity value assigned to a data packet in a transmission buffer.

Abstract: A method for operating a node in a communications network for coordinating transmissions of different nodes in the network to improve coordination of communication between network nodes. The node includes a validity state and estimation module, wireless state monitor module, wireless configuration space module, and wireless configurator module. The VSE assigns a data validity value to a data packet and/or to a transmission buffer of the node. The data validity value reflects the usefulness of the data packet for an application and is preferably age based. The WSM gathers physical transmission property data indicative of transmission properties of a communication link provided by the network between the node and another node. The WCS determines a parameter configuration space amenable for transmitting the data packet via the communication link and the WCON sets corresponding transmission parameters based on the data validity value and physical transmission property data.
