About the NAV System
The Extron NAV decoders and one or more compatible encoders form an AV distribution
and switching matrix on an Internet Group Management Protocol (IGMP) Managed IP
Network. The encoders are configured for low latency multicast streaming. The decoders
are configured to join the assigned multicast group.
About the Encoder
A NAV encoder encodes inputs from an HDMI video source, compresses them into a data
stream, and streams the coded signal 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 data stream can include:

Features
NAV SD 501 Scaling Decoder — Receives HDMI video, audio, and RS-232 and IR
communications via a managed IP network using multicast streaming technology. Also
supports USB and Ethernet extension.
NAV SD 101 Scaling Decoder — Receives HDMI video, audio, and RS-232 and IR
communications via a managed IP network using multicast streaming technology.
•
The NAV SD 501 and NAV SD 101 are both referred to as a "decoder." They are
referenced by model name when differences exist.
•
NAV decoders and encoders collectively are referred to as "endpoints."
