voLANte DiVAS Distributed AV Matrix Switching Solution
The voLANte DiVAS distributed AV matrix switching solution is a revolutionary approach to switching HD video signals using enterprise-class network switches. By leveraging the reliability, cost, and features of off-the-shelf network switches commonly used to send data and voice over IT infrastructures, DiVAS switches multiple video streams significantly faster, less expensively, and in a smaller footprint than traditional analog matrix switches. No other matrix switch matches the ease and range of scalability of the DiVAS system. Switching can be implemented from 10x10 to 1000x1000 with complete reuse of hardware.
The DiVAS switching solution is enabled by the video-over-IP capability of voLANte's video extension products. VoLANte's video-over-IP transmitters generate IP Multi-Cast packets that are efficiently handled by network switches and routers. A distributed matrix video switcher can be constructed from multiple IGMP-enabled network switches located in separate buildings but tied together by high-speed fiber trunk lines on the switch. In this distributed scenario, any input video channel in any building can be routed to any output video channel in any building.
Using technology unique to voLANte, each DiVAS switch port can accommodate up to 10 independent video stream inputs and each output port can accommodate 10 independent video stream outputs. Each output can be daisy-chained to an unlimited number of displays as long as no more than 10 separate streams are requested from one switch port. voLANte receivers convert the Ethernet packets back into synchronized video and audio for display. Bi-directional serial signals allow control of each display independently.
Since network switch modules can be configured independently, any combination of copper, fiber, or wireless data switches can be used for a given video matrix switch installation. DiVAS's scalability and configurability represent a significant advancement in audio-visual matrix switching and represent a future-proof investment as corporate IT infrastructures evolve.

The voLANte DiVAS controller is an optional control and diagnostics interface to a DiVAS switching system. The DiVAS controller provides a confidence viewer for real-time viewing of each video stream, provides diagnostic and health status for all video, audio,and control signals, and supports integration with third-party control systems. The controller may be accessed locally or remotely through a web enabled interface.
