New in 2.0 · Pro and Enterprise
Castreon Studio: a live production control room, right on the server
Scenes and transitions
Up to 16 sources in 24 scenes: channels, IP cameras, streams, files, clip playlists, web pages. PREVIEW and PROGRAM, TAKE with a fade, a dip to black or a stinger.
Live graphics
Lower thirds, a news ticker, a clock, a score and your logo, changed on air without stopping anything — plus web pages with a transparent background over the picture.
Guests from the browser
Send a link and the guest joins with their own camera and microphone. They see what is on air and hear the programme without their own voice (Enterprise).
Mixer with effects
Volume, Auto / On / Off per source and background music; on every source a delay for lip sync, a 3-band EQ and a compressor.
Replays and recording
The last seconds of any camera, in slow motion. REC records PROGRAM and every camera separately, straight into the Library.
IP and PTZ cameras
RTSP straight into the studio, ONVIF discovery and PTZ control (ONVIF, VISCA) from the desk: hold to move, zoom, stored positions.
No separate production software and no control-room computer: everything runs on the server, the browser only gives the commands. The studio goes on air through a Castreon channel, like any source. Guide: Castreon Studio →
New in 3.0
Broadcast-grade reception, measurement and multiplexing
TR 101 290 on every mux
Priorities 1–3 measured all the time on every DVB mux, with counters, explanations and alerts. The transponder monitor scans whole satellites and networks on a schedule and reports what changed (Enterprise).
Motorized dishes and Unicable
DiSEqC 1.2 and USALS positioners with installation controls in the panel; Unicable I and II on a single cable for several tuners.
ATSC, ISDB-T, DTMB
The digital TV of the Americas and Asia next to DVB, with virtual channel names (PSIP) and Japanese texts (ARIB) in the service list and the guide.
Common Interface
A CA module in the card’s CI slot decrypts the programmes your channels use; the module’s own menu opens right in the panel.
MPTS and modulators
Several channels in one constant-rate multiplex with its own tables and LCN, over UDP or RTP, or straight to an ASI card or a modulator (Enterprise).
SDI / HDMI and radio
Capture cards (V4L2, DeckLink) as sources, plus FM and DAB+ radio through an SDR receiver — on air with your “no signal” picture.
Subtitles in HLS
A WebVTT track that every player can switch on, made from teletext, from DVB subtitles read with OCR, or from speech.
Operations
SNMP with a MIB for your monitoring (Enterprise), automatic backups, a per-second log of every channel, Rocky Linux and RHEL, automatic security updates.
A walk through the panel on a demo server: channels, failover, transcoding, the library and schedule of 24/7 channels, audience, clips and settings. No sound; subtitles in five languages.

Pro and Enterprise
24/7 channels from your own files
Library and playlists
Films, episodes and clips uploaded from the browser or from a synced folder. Playlists in fixed or shuffled order, intro / outro, filler and a logo on each channel.
No black screen between titles
Each file is prepared once — resolution, logo, subtitles, equal loudness — then aired without re-encoding, with continuous timestamps. Preparation runs on the GPU where there is one.
An EPG from what really airs
A 7-day TV guide, also as XMLTV, built from the channel's real timeline. In Enterprise: a day / hour schedule, live takeover, SCTE-35 ad breaks and an as-run report. Plus an automatic “Now on …” guide channel, built from your channels' schedule and picture (Enterprise).
State, version, processor and graphics card, memory, disk, channels, license and certificate of each server. When a server stops responding, you get an alert by e-mail, Telegram or webhook.
Work on any server
Pick the server in the top bar and the whole panel — channels, profiles, settings — works on it. Each user's role applies there too.
A channel from another server as a source
One station receives, another server distributes: the channel travels between them encrypted, with TLS 1.3 and certificates on both sides — no addresses or passwords copied by hand.
Real screenshots from the Castreon web panel, taken on a demo server. No separate monitoring tool needed — channels, alerts and settings live in one place.
Channels
Every channel, live, at a glance.
A live picture taken from what you deliver — the source is never touched.
Bitrate, frames per second, CPU, memory and viewers in real time.
Every delivery address one click away: HLS, DASH, WebRTC and more.
castreon · Channels
Failover
Built not to go dark at 3 a.m.
When the primary source goes silent, the backup takes over automatically.
Every switch appears in the channel’s events, with the reason.
Channels that get stuck are restarted by the watchdog on their own.
castreon · Channels
Transcoding profiles
Write a profile once. Use it on every channel.
ABR ladders, a single quality or passthrough, on CPU or GPU.
Edit a profile and only the channels that use it restart.
Ready-made recipes for the usual cases: HD, ABR, SD, headend feed, passthrough.
castreon · Profiles
Library · Pro and Enterprise
Your files, ready for 24/7 channels.
Films, episodes and clips uploaded from the browser or picked up from a synced folder.
Each file is prepared once — resolution, logo, subtitles, equal loudness — then aired without re-encoding.
Filters show at a glance what is ready, what is still being prepared and whose rights expire soon.
castreon · Library
Schedule · Enterprise
A weekly grid, block by block.
Each block of the day plays its own playlist; the default one fills the rest.
Date exceptions for holidays, events or a live takeover.
Check what airs at any date and time — the TV guide is built from what really airs.
castreon · Channels
Clips and recordings · Pro and Enterprise
MP4 clips, without re-encoding.
From a channel’s archive, from the library or recorded right now.
Scheduled recordings — once, daily or on chosen days — and each run becomes a clip.
Download it, send it to S3 storage or share a viewing link in the player.
castreon · Clips
Monitoring wall · Enterprise
Every channel on one screen.
Live picture, audio levels, bitrate and viewers for each channel.
Problems blink until someone marks them as seen, with an optional sound alarm.
Display links for control-room screens; click a channel for live video with sound.

Security
Access stays under your control.
Allow lists for streams and metrics: IP addresses, networks or ranges.

Stream protection
Encrypted contribution
Receive and send feeds over SRT with a passphrase, or over RIST with AES-128 or AES-256 encryption.
Who can pull your streams
IP allow-lists for HLS, DASH and HTTP-TS — for the whole server or per channel. Addresses, networks and ranges, IPv4 and IPv6. Plus signed viewing links that expire — checked by the server or by the CDN (Enterprise).
DRM for your outputs
Encrypt the channels you deliver to your subscribers: HLS AES-128 with a built-in key server on every plan, and Widevine, PlayReady and FairPlay with the DRM provider of your choice (Enterprise).
Runs unattended. Tells you when it can’t.
Failover between sources
Give each channel a primary and backups. Castreon switches when the primary fails and returns when it recovers. If no source is left, viewers see your “no signal” image instead of a stopped player. With several CDNs, compatible players move on their own to the CDN that works (Enterprise).
Watchdog and alerts that reach you
Stuck channels restart by themselves. Failed sources, black or frozen pictures, silent audio, weak DVB signal, a wrong BISS key and a loaded server show up in the panel — and reach you by e-mail, Telegram or webhook.
Channels on demand
Rarely watched channels start with the first viewer and stop when the last one leaves.
Updates, backups, metrics
One-click updates with automatic rollback, backup and restore, Prometheus metrics for Grafana.
14 days free, on your own server.
Create an account, run the install command and test Castreon with your real channels. Every Pro feature, up to 10 channels. No credit card and no automatic charge — subscribe only if it works for you.
