SRT to UDP for your HeadEnd distribution
Receive SRT contribution and convert it to clean UDP multicast for your multiplexers, QAM and set-top boxes. It is an affordable gateway built for 24/7 channel delivery.
The Challenge
Contribution arrives over SRT. Your HeadEnd speaks UDP multicast
SRT is the reliable way to bring a channel across the internet or a managed WAN, but it is point-to-point: it can't feed a HeadEnd on its own. Your multiplexers, edge QAM and set-top boxes expect UDP multicast on the local network.
SRT Gateway by CEF bridges that gap affordably: a Raspberry Pi or Linux appliance receives the SRT (or HLS) contribution in caller mode and republishes it as clean UDP multicast for the HeadEnd, with automatic failover, per-program monitoring and a cloud fleet panel, so a channel or a whole lineup stays on air 24/7.
Architecture
From SRT contribution to multicast distribution
Why operators choose it
HeadEnd-grade delivery, without HeadEnd-grade hardware bills
Keep channels on air
A backup source takes over automatically when a contribution link drops. Subscribers never see a black screen.
Know before the NOC calls
Per-program bitrate, packet loss and RTT, live, with email alerts on signal loss, black screen or pixelation.
Run every HeadEnd from one panel
Monitor and configure every gateway across every HeadEnd remotely, from one cloud dashboard.
FAQ
Cable & IPTV HeadEnd questions
How do I convert an SRT contribution feed to UDP multicast?
Point the gateway at your SRT source in caller mode, either a full multiplex or a single program, and set a UDP multicast output. It demuxes the stream and republishes clean UDP multicast that your multiplexers, QAM modulators and set-top boxes consume directly, with no separate hardware gateway.
What happens if a contribution link fails?
Configure a primary and a backup source. Failover switches to the backup and auto-reconnects when a feed drops, and email alerts notify your NOC the moment a program goes out of range.
Which hardware fits a cable operator?
Raspberry Pi 4 or Pi 5 handle up to 20 streams each (with HDMI output on the Pi 5); a Linux server scales to up to 250 streams and also offers HDMI. All of them are managed from the same cloud fleet panel.
