Abstract
A number of cameras capture a scene and send corresponding video sub-streams to an acquisition PC. Each sub-stream is made up of a plurality of sub-frames. The acquisition PC sends the sub-streams over a network to a playback PC. The playback PC stores each sub-frame in a queue corresponding to an associated sub-stream. For each sub-stream the playback PC calculates a sub-stream average period to produce a plurality of sub-stream average periods. It then calculates a composite average period by averaging the plurality of sub-stream average periods, and calculates a playback frame rate as a reciprocal of the composite average period. The playback PC then reads the sub-frames from their corresponding queue in synchronism with the calculated playback frame rate to display the plurality of sub-streams.
