As simulation evolves from single cockpit trainers to integrated multiple cockpit configurations, the need to provide real-time exercise monitoring and debrief capabilities becomes critical to a complete training environment. This paper examines the current state of the art in video compression and storage to solve problems related to monitoring an on-going training session in real-time and provide playback capabilities for debrief. A case study of the Sensor Video Recording System (SVRS) developed by L-3 Communications Link Simulation and Training in the U.S. Army s Aviation Combat Arms Tactical Trainer -- Aviation Reconfigurable Manned Simulator (AVCATT-A) is discussed. The SVRS uses digital video compression and network streaming to solve monitoring/debrief requirements. The current resolution limitations, image artifacts, and storage requirements of video compression techniques are analyzed. Video regeneration is also examined as an alternative to video compression and storage. The limitations and latencies involved in network streaming are summarized along with lessons learned in developing a multichannel digital video system.
