Comprehensive 2026 Bandwidth Reference Guide Published for IP Video Protocols
iView Data Ltd, an authorized UK Magewell reseller, has published a comprehensive 2026 reference guide detailing bandwidth requirements for IP video protocols including NDI, SRT, RTMP, HLS, and RTSP. The guide provides essential data for various resolutions and frame rates, aimed at AV integrators, broadcast engineers, and IT managers for effective IP video system design and bandwidth planning.
Key Takeaways
- Full NDI for 1080p60 requires 125-200 Mbps, saturating a Gigabit switch with 5-6 streams; NDI HX3 offers near-full quality at 62 Mbps max.
- SRT requires 25-40% bandwidth overhead above encoded bitrate for packet retransmission, essential for connections with 5-10% packet loss.
- RTMP bandwidth requirements are platform-specific (e.g., YouTube 4K30 maxes at 51 Mbps, Facebook 1080p30 at 4 Mbps), with H.264 as the common codec.
- Common errors include running Full NDI over Wi-Fi, ignoring SRT overhead, using ISP headline speeds, and exceeding RTMP platform maximums.
- HLS is for CDN/web delivery (6-30s latency), while RTSP is for LAN monitoring/IPTV (1-3s latency); neither is suitable as a contribution protocol.
Why It Matters
Understanding current and future IP video bandwidth requirements is critical for avoiding costly infrastructure overhauls and ensuring reliable streaming. As production workflows increasingly shift to IP, precise planning for protocols like NDI, SRT, and RTMP directly impacts latency, video quality, and system stability. This guide indicates a continued diversification of protocol use based on specific network conditions and application needs, rather than a single dominant standard. Industry professionals should monitor protocol updates and platform-specific requirements, especially as H.265 adoption for RTMP ingestion remains limited among consumer platforms, to optimize their streaming infrastructure.
