1. An aircraft comprising:
a system for synchronized data playback comprising:
at least one offset calculation device;
a plurality of clients; and,
a plurality of decoders, each decoder associated with one client from the plurality of clients,
wherein the plurality of clients are each synchronized to a shared reference timeframe,
wherein each of the plurality of clients is configured to receive a common set of timestamped data frames,
wherein 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,
wherein 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,
wherein each of the plurality of decoders processes the common set of timestamped data frames to provide a synchronicity between the clients of the plurality of clients, and
wherein each of the plurality of clients determines a processing characteristic in which the decoder associated with said respective client processes the common set of data frames to restore the synchronicity, the processing characteristic selected from a group consisting of:
a speed at which the decoder processes the common set of data frames; and
a number of frames processed by the decoder including less than and including a total number of frames in the common set of data frames.
