From the broadcast day you already run to a channel on every screen.
A station that already fills a broadcast day does not rebuild it for the internet. Internet TV broadcasting software takes the same jobs, programming, live inserts, and distribution, and runs them from a dashboard. This is the path.
Build the channel
-
1. Load the library
Upload programs into the playout's files, where live-to-VOD recordings of past broadcasts also appear automatically. Recordings capture up to 72 hours and stay available for three days, and saving one to the library is what keeps it.
-
2. Program the timetable
Schedule items in sequence or loop a playlist continuously. Every plan includes one playout channel.
-
3. Insert live shows
Add any livestream to the timetable, so news bulletins and live events air inside the scheduled channel.
Deliver everywhere
-
Website player
The channel plays in the embedded player on your own site over multi-CDN delivery, on every plan.
-
Social and custom endpoints
Multistream the channel to YouTube and Facebook, and reach TikTok or Instagram through custom RTMP, within account-wide destination totals that can be raised on request.
-
OTT apps
The Events plan includes a branded web app, typically live within 48 hours, and native mobile and TV apps are scoped separately.
Native apps typically take 30 to 90 days, mostly app store review.
Operate and earn
-
Program guide
Pull the channel's EPG as JSON from the API to power schedule pages and app guides.
EPG is on Premium and higher.
-
Output quality
Playout outputs 720p at 30 fps on lower tiers, and 1080p at 25 to 60 fps on Ultra and Events.
-
Monetization
Run in-stream ads from Standard and higher, gate premium content with the paywall on any plan, or sell subscriptions through the OTT service.
Radio works the same way: audio-only streams play in the embedded player, and adding a static image or visualizer as the video track makes the stream accepted by social platforms.

Designed for recurring, accountable video work.
Operational complexity matters more than company size. The strongest fit is a team with a named owner, a repeatable schedule, and a real consequence if delivery fails.

Switching to Castr
Move the station without a second off air.
You do not have to cut over blind. Run Castr in parallel with your current provider while you test, and let our video team confirm the fit before anything switches.
Run in parallel
Run the channel in parallel on Castr, as a 24/7 playout rundown or a live contribution feed, while your current system keeps broadcasting. Let it run for a few days and check that the schedule holds.
Map the workflow
Our video team reviews your contribution protocols, programming calendar, output requirements, and distribution list, then confirms which plan covers the channel.
Cut over with support
Repoint your website player, apps, and destinations once the parallel channel has held its schedule, with 24/7 human support on hand through the first broadcast week.
Build the complete workflow
Connect this capability to the rest of your operation.
Questions before you choose
Evaluate the workflow with confidence.
Feature and plan availability changes by tier. Use the full matrix for comparison, or let our team validate a complex setup.
How do we bring an existing TV station online?
Bring the programming you already run. Upload the library into a 24/7 playout channel, insert live shows from master control into the timetable, and the channel plays on your website, in OTT apps, and on social platforms. If you are building a brand-new internet-only channel instead, the TV playout page walks through that workflow from scratch.
What does it cost to put our channel online?
Far less than extending traditional broadcast infrastructure. Every Castr plan includes one playout channel, so the online channel starts at the price of whichever plan you choose, plus your content and encoding costs, instead of transmitters, satellite capacity, or racked playout servers. Higher tiers raise output quality to 1080p at up to 60 fps.
How do we stream our radio station online?
Send the station feed from any RTMP or SRT encoder and embed the player on your website, with the same recording, scheduling, and multistreaming the video platform provides. Social platforms reject audio-only streams, so add a static image or visualizer as the video track before simulcasting there.
Can we insert live news into a scheduled channel?
Yes. Live stream insertion adds any livestream from your dashboard to the playout timetable, so a bulletin or breaking coverage airs inside the scheduled channel and hands back to the rundown.
What contribution protocols do you accept from master control?
RTMP, SRT, HLS, RTSP, and MPEG-TS, with SRT included on every plan. Castr can also pull from a source you host, and 40+ ingest locations keep the contribution leg short.
Can we deliver to our website and OTT apps?
Yes. Embed the player on your website on any plan, and Premium and higher add an HLS URL for your own apps. The Events plan includes a branded web app, typically live within 48 hours, with native mobile and TV apps scoped separately and typically taking 30 to 90 days.
Can Castr support continuous channels?
Yes. There are no streaming-hour limits, so channels can run 24/7, and cloud playout schedules live and recorded programming into a continuous rundown.
Can Castr replace on-premise playout entirely?
For many channels, yes. Cloud playout schedules files and live inserts into a continuous rundown, transcodes uploads to the channel's output configuration, and outputs 1080p at up to 60 fps on Ultra and Events. Channels with hard requirements the dashboard does not cover, like frame-accurate ad splicing, should review the workflow with the video team first.
Can Castr help us validate our current workflow?
Yes. Castr’s video team will walk through your current setup, from sources and destinations to audience scale, security, and monetization, and confirm the fit before you migrate.
