Kylone
The Complete Broadcast Headend. In Software.
Licensed as software, with the functions fixed per product. Run it on your own servers, or on a turnkey appliance from a hardware partner. The same product either way.
Why Kylone
What sets Kylone apart
A broadcast headend for operators with obligations on the signal, and for every network downstream of them. Reception to RF, transcoding to OTT, control of what goes on air and what stands in when a source fails — and the same engine serving a hotel, a campus, a vessel or a hospital, on set-top boxes, hospitality TVs, phones, tablets and PCs. Built and refined in the field for a decade.

Control of the Signal
Scheduled stand-ins for blackout windows, audio substitution by grafting a track, SCTE-35 cues for insertion, and a video wall for the control room — the Broadcast product. Underneath, in every product: automatic backup one-to-one or one source guarding many, with return, and through every switch the channel keeps its on-air identity, so receivers never re-scan.
Every Input. Every Output. One Engine.
DVB-S/S2, T/T2, C, ATSC, ISDB-T, IP, HDMI and files in; IPTV, HLS, SRT, RTSP, DVB-C/T RF and ASI out — simultaneously, with broadcast-grade timing and live configuration changes.
Studio-Grade Processing
Transcoding on NVIDIA, Intel QuickSync and AMD — even mixed in one server, load-balanced — with EPG, subtitles and captions carried through, not lost. Adaptive HLS ladders, assistive captions made at the headend, extra outputs: the Studio product.
OTT-Ready by Design
Modern HLS with adaptive bitrate ladders of up to six variants per channel, multi-audio renditions and WebVTT subtitles, high-capacity multi-core SRT, RTSP with authentication, RTMP push — your headend is already your OTT origin.
Conditional Access, Both Directions
Standalone CI not tied to a tuner — clear any input, including IP sources, through hardware CAMs, several services per module. BISS both ways. Nothing advertised that has not shipped.
RF Where You Need It
DVB-C/T modulation straight from the headend over the building’s existing coax — complete tables, working channel numbers, no TV replacement, no re-scan surprises.
An Open Module Architecture
Kylone-built transcoding and HLS-output modules, GPL-clean and fully redistributable, CPU-capable everywhere, included in the licence and installed when you want them. Need a stage of your own? Custom modules are built under contract.
Captions, Made at the Headend
Channels without text subtitles get them: DVB bitmap subtitles read into text, or speech recognised on the GPU — in the spoken language or translated to English — delivered as a subtitle page every TV, set-top box and HLS player already understands.
See Everything
Real-time visibility down to PIDs, table timings, PCR behaviour and per-stream errors — with live logs, a standalone EPG viewer, SNMP, Prometheus and XML feeds your own NMS can consume.
Built to Run Unattended
Self-healing by design: automatic source recovery, watchdogs, no-signal handling, central fleet management — the system’s first responder is the system.
Honestly Connected
Remote access free of charge on a private network of your own units, validation data enumerated in the licence agreement — and the switch is yours: turn remote access off and the service on the unit stops. Private central portal available.
And the Hospitality Headend
The same engine for a property: hospitality-TV and Android STB fleets with OTA upgrades, PMS integration, per-package content, timeshift, emergency alerts and signage — and a headend any hospitality application can build on: channel lists, programme guide, logos and HLS, published as open feeds.
Products
Six products, one line of thought
Digital Headend Gateway
DVB in, IP out: tuner cards on one side, multicast, SRT, HTTP and HLS on the other, with the full web UI, the API and the monitoring of every product.
In detail →Digital Headend Advanced
Every source and every output: IP contribution, files, HDMI and SDI capture; multiplexing and DVB-C/T modulation; modules and white-label branding.
In detail →Digital Headend Studio
Advanced plus processing: GPU transcoding, assistive captions, adaptive HLS renditions, extra outputs. Where content gets processed.
In detail →Digital Headend Broadcast
Studio plus control of the signal: scheduled stand-ins for blackout windows, audio substitution, SCTE-35 cues, a video wall. For operators with obligations on the signal.
In detail →Hospitality Headend
Studio for a property plus the client side: set-top box and TV lines, PMS integration, guest hotspot, the line-up any middleware reads.
In detail →Carrier Monitor
A blind-scan appliance that finds every carrier on a satellite feed, reads the programme tables and reports what changed since the last run.
In detail →Hardware: yours, or turnkey.
Kylone runs on standard x86 servers with the Linux DVB driver stack and drives any tuner, modulator or capture card those drivers support. If you would rather buy one unit from one supplier, a hardware partner ships Kylone pre-installed on its appliances, from a compact unit to a multi-GPU rack, with the same licence and the same product.
