Extron’s new VNS 104 Multi-Stream Decoding Software decodes and presents one or four video sources and one associated stereo audio source streamed from VN-Matrix 225 or 200 Series Encoders and VN-Matrix Recorder. VNS 104 multi-stream decoding software includes text overlay and status messaging features, which are valuable for distinguishing between AV sources during operation and system commissioning.

VNS 104 multi-stream decoding software operates on Windows PCs and is managed as a part of a system by a VN-Matrix Enterprise Controller. It offers aspect ratio management for VN-Matrix streams, including FILL, FOLLOW and a 1:1 mode, which can be applied independently to each decoded source. VNS 104 provides an effective method for monitoring multiple streaming sources in a variety of environments including command and control, after action review, training and simulation, and medical or geological visualization.
