NOViSS is a system for providing reliable delivery of live streaming video over tactical wireless networks using NACK-Oriented Reliable Multicast (NORM). NOViSS can provide end-to-end reliable transport of multicast streaming video to overcome latency and packet loss problems associated with limited-bandwidth wireless tactical networks.

Features

  • Reliable delivery of streaming video over tactical wireless links using NACK Oriented Reliable Multicast (NORM) protocol (IETF RFC 5740)
  • Video digitizer with compression to allow network distribution of video over disadvantaged links
  • Bandwidth reduction techniques to reduce network traffic
  • Video distributed throughout battle group network and beyond
  • Video can be viewed throughout the battle group over WARNET/IBGWN and other IP communication services
  • Web-based viewer and system control interfaces
    • Embedded video display is implemented via the QuickTime plug-in that supports a variety of web browsers
    • Full-screen display is also supported
    • Video legend can be added by the transmitter to provide a source description (e.g. "P3 Airborne Patrol") to remote viewers
