Signals come in. Television goes out.

The complete TV headend. Software first.

Receive HLS, SRT, RTMP or MPEG-TS. Deliver MPEG-TS multicast to set-top boxes, or DVB-C on the coaxial cable already in the walls. Install it on a Linux server you already own — or buy it ready to plug in on one of our fanless boxes.

What it does

The whole signal path, end to end.

Castmux sits between the content you buy and the sockets you already have.

Signals arrive from the internet as SRT, HLS, RTMP or UDP, from another headend as MPEG-TS over UDP multicast or HTTP, or on site from your own barker channel, a camera or an encoder. Castmux receives them, prepares the transport stream, and delivers them to the building as UDP multicast over the LAN, or as DVB-C on the existing coaxial cable. — The whole system. One process on one machine — yours or ours.

Is this for you?

Built for buildings, not for broadcasters.

Sites with 10 to 200 channels and no full-time broadcast engineer.

🏨

Hotels

Guest languages, your own information channel, and no set-top box in the room.

🏥

Hospitals

Silent, sealed, ward-by-ward line-ups over multicast or DVB-C.

🏡

Care & elderly homes

A short curated list, a house channel for activities and services, no room visits.

📡

Small cable operators

Real multiplexes, stable service identity, and capacity you can see.

How does it work?

One process, one web page.

No separate ingest server, muxer, modulator tool or monitoring stack.

Receiving content

HLS, with the quality rung you choose
SRT, with latency set from measured RTT
RTMP from a local encoder

roadmap RTP, RTSP and satellite, terrestrial or cable tuner input

📤

Delivering content

MPEG-TS over UDP multicast or unicast
DVB-C multiplexes via numerous DVB modulator brands

The software

One web page runs the whole headend.

Add a channel, watch it in the browser, and see what is actually leaving the network port. No command line, no configuration files to hand-edit.

Channel management screen: one card per channel with source, destination, live bitrate, uptime and viewer count. — Channels — source, destination, live bitrate, viewers and logs on one card.

DVB-C screen: multiplexes shown by frequency, with channels dragged and dropped between them. — DVB-C — drag channels between frequencies, with live capacity per multiplex.

Hardware

Or buy it ready to plug in.

The software is the product. If you would rather not source and build a machine, we ship it preinstalled and preconfigured on two fanless boxes.
