PASS
166.8 Mbps/stream

More efficient than H.264. Lower bandwidth for same quality. Runs on 1GbE.

Planning Notes

Bandwidth estimates use conservative compression ratios for worst-case planning. Actual throughput varies with content complexity.

With multicast + IGMP snooping, backbone bandwidth = unique streams only. Without IGMP, every port receives all streams.

Always verify switch backplane capacity and per-port throughput in addition to link speed.

Reserve bandwidth for PTP/control traffic, OS updates, and burst headroom.

Using This Calculator for System Design

1. Map your signal flow

Identify every video and audio stream in your system. Each encoder-to-decoder path counts as a stream. Include presentation sources, camera feeds, digital signage, and audio DSP matrix sends/returns.

2. Choose the right protocol

Match the protocol to your hardware. Uncompressed protocols (SDVoE, ST 2110) deliver highest quality but need 10G infrastructure. Light compression (NVX, NDI) works well on 1G. Heavy compression trades latency for lower bandwidth.

3. Account for overhead

Reserve 10-20% for control system traffic (Crestron, Extron, AMX), PTP/NTP synchronization, IGMP snooping queries, and firmware updates.

4. Verify your network

Check not just link speed but also switch backplane capacity (total throughput across all ports), per-port throughput (some switches share bandwidth between port groups), and multicast support with IGMP snooping.

5. Plan for growth

Keep utilization below 70% to accommodate burst traffic and future expansion. A network running at 95% will drop frames during peaks even if average bandwidth looks acceptable.
