within six months, followed quickly by a six-month prototype refinement period to create a more ruggedized version.
As a first step, NVESD conducted an architecture study to determine how best to meet the overall project goal. NVESD identified three target system architec- tures. NVESD designed the
software
prototypes for each architecture and collaborated with hardware vendors to design the hardware prototypes that would demonstrate the architectures. Common to each approach was the need to convert the MMPV Type II legacy analog camera data to digital and then fit the data into the available bandwidth for each display. Te aggregate band- width of all the different vehicle-enablers is roughly three times more than most common commercial off-the-shelf inter- faces can handle.
Te three architectures varied mainly in where they collected imagery and how they disseminated it to the displays. A centralized architecture
collected the
images at a central server with dedicated image-capturing hardware that com- pressed the imagery and sent it out to the displays. A distributed architecture had image-capturing hardware in each display to capture a subset of the images, which it compressed and passed to the other dis- plays. A network-centric approach used stand-alone media converters to capture the imagery and a server switch to com- press it and send it to the displays.
Te network-centric architecture was deemed the best of the three. It has ample hardware redundancy to survive various kinds of hardware failure as opposed to the centralized approach, which would be crippled by the failure of the central server. It minimizes the number of components required in the displays, keeping them thin and light for rapid vehicle ingress
EYES EVERYWHERE
The graphical user interface of the MVD system establishes a common monitor and interface to view and operate many simultaneous real-time video feeds. The system can also act as a digital video recorder, allowing for the capture and playback of video sequences and snapshots.
MOVING INTO FOCUS
An MVD plug-in enables use of high-magnification sensors, which means that crews can perform roadway and roadside threat detection at extended ranges while on the move.
