Approach to distributing audio and video signals using standard IP network infrastructure instead of traditional point-to-point cabling or proprietary matrix systems.
Common protocols:
- SDVoE: Zero-latency 4K60 4:4:4 over 10GbE
- Dante AV: Audio + video from Audinate
- NDI: Software-based, compressed or full bandwidth
- NVX (Crestron): 4K60 4:4:4 over 1GbE (proprietary)
- NAV (Extron): 4K60 over 1GbE (proprietary)
Key points:
- Replaces traditional matrix switchers with network switches
- Scales easily — add endpoints without replacing infrastructure
- Requires proper network design (VLANs, QoS, IGMP snooping)
- Latency varies by protocol: SDVoE < 1 frame, NDI|HX ~2-4 frames
