Extron NAV
Extron NAV is Extron's AV-over-IP platform — it replaces traditional HDMI matrix switchers by distributing video and audio across a standard Ethernet network. An NAV encoder (connected to a video source) converts the signal into encrypted network packets using Extron's proprietary PURE3 codec; an NAV decoder (connected to a display) receives and converts them back to video. Routing is managed by the NAVigator, a dedicated hardware appliance with a browser-based interface. NAV competes directly with Crestron NVX and is a credible alternative in corporate and higher-education AV. It supports AES67 audio interop, AES-256/FIPS 140-2 security, and 802.1X network access control — features that make it viable in government and secure enterprise environments.
Scope: Extron NAV — select the deployed product/version; optional services require separate selection.

Gotchas & IT Notes
- ⚠Apply the encoder, decoder and NAVigator normal/OOB table for the actual device role. This page groups the documented feature profiles.
- ⚠Encoder AES67 5005 is documented separately from decoder 5004; do not relabel it RTCP by assumption.
- ⚠802.1X backend RADIUS belongs between the authenticator and server. It is not automatically a NAV endpoint outbound service.
