About this Guide
This guide contains installation, configuration, and operating information for the Extron®
VN-Matrix® VNC 325 encoder/decoders (codecs).
NOTE: This guide describes the operation the VN-Matrix 325 with version 4.6 or later
firmware.
About the VNC 325 Codec
The VN-Matrix VNC 325 video codecs (see figure 1) distribute digital SD, HD-SDI, or 3G-SDI
broadcast quality video and audio content across an IP network using the Extron PURE3®
Codec algorithm. PURE3 exceeds many of the performance characteristics of existing
compression formats and provides exceptionally robust protection against network errors,
making it ideal for quality-critical applications. The VNC 325 codec can be configured to
operate in one of two modes:
• As an encoder to encode a source and stream it across a network,
• As a decoder to decode a VN-Matrix 325 encoded data stream from a network.
