SRT to UDP gateway
SRT to UDP Gateway
Receive SRT and convert it to UDP unicast and multicast, the transport your HeadEnd, multiplexers and set-top boxes expect, reliably and 24/7.
The basics
What is an SRT to UDP gateway?
An SRT to UDP gateway receives a live video stream over the SRT protocol and re-emits it as UDP, unicast to one endpoint or multicast to many, so it can be distributed across a local IP network. SRT Gateway by CEF receives SRT (in caller mode) and HLS, and outputs UDP unicast, UDP multicast and HLS, built for continuous 24/7 delivery.
SRT is the reliable, error-corrected way to move a channel across the public internet or a managed WAN. But HeadEnds, multiplexers and set-top boxes speak UDP on the local network, so a gateway is what turns that incoming SRT feed into the UDP your infrastructure can actually use.
SRT to UDP multicast
Why you need a gateway to reach multicast
SRT is point-to-point, so it can't feed many receivers on its own. The gateway converts it to native UDP multicast.
One SRT session in, native UDP multicast out, ready for a HeadEnd, multiplexer or set-top boxes.
Why SRT Gateway by CEF
The affordable, manageable SRT to UDP gateway
Runs on a Pi or Linux
Up to 20 streams on a Raspberry Pi and up to 250 on Linux, with HDMI output on the Pi 5 and Linux.
Automatic failover
A backup source takes over automatically when the primary drops, so there is no black screen.
Monitoring + email alerts
Per-program bitrate, packet loss and RTT, with email alerts on signal loss, black screen or pixelation.
Managed from the cloud
See and configure every device remotely from one cloud fleet panel.
FAQ
SRT to UDP questions
How do I convert SRT to UDP multicast?
Point the gateway at your SRT source in caller mode, choose the full multiplex or a single program, and set a UDP multicast address and port. It demuxes the stream and re-emits it as UDP multicast on your LAN, ready for a HeadEnd, multiplexer or set-top boxes.
Does SRT use UDP, and can SRT do multicast?
SRT runs on top of UDP but is point-to-point (unicast), so it cannot multicast on its own. An SRT to UDP gateway terminates the SRT session and re-emits the stream as native UDP multicast for your local network.
Which hardware does it run on?
Raspberry Pi 4 or Pi 5 for up to 20 streams each (with HDMI output on the Pi 5), or a Linux server for up to 250 streams with HDMI. All are managed from one cloud panel.
Is it built for 24/7 delivery?
Yes. Caller-mode SRT input, automatic failover, live monitoring and email alerts keep the UDP output flowing around the clock.
