Video over Internet for Broadcasters
Carry an HD-SDI or SD-SDI signal over the internet in real time to a distant location and recover it as SDI at the destination: with a BLANKOM encoder with SDI input and an IP decoder or professional IRD with SDI output.

Tell us your source (HDMI, SDI), where the video goes and the internet speed at both ends; we will suggest the matching encoder and receiver. We ship worldwide from our warehouses in Germany and Turkey.
What is needed?
| What is needed | |
|---|---|
| Sending end | BLANKOM encoder with SDI input |
| Receiving end | BLANKOM IP decoder or professional IRD with SDI output |
| Connection | An internet connection at both ends (ADSL, VDSL, fiber or mobile) |
The link can be set up in two ways: you push the content from your site to the distant location, or you pull the signal from the distant location to your site. An internet connection is needed at both ends.
Recommended internet speed
- H.264 encoding: we recommend an upload speed of at least 2 Mbps for SD and at least 4 Mbps for HD.
- H.265 (HEVC) encoding: we recommend an upload speed of at least 1.4 Mbps for SD and at least 2.8 Mbps for HD.
- These figures are PROTEL’s application guidance; the speed needed depends on the picture content and the quality required.

Frequently asked questions about SDI transmission for broadcasters
Is a static IP address needed for live transmission over the internet?
It depends on the set-up. Where the stream is pushed to a platform or server it is generally not needed; where it is pulled from the distant location the sending end has to be reachable. Describe your project and we will suggest the set-up.
How much delay is there?
The delay depends on the protocol, the encoding settings and the internet connection; the actual figure is measured on the installation.
What is the SRT protocol for?
SRT (Secure Reliable Transport) is a transport protocol developed for carrying live video over networks with packet loss, such as the public internet. According to the manufacturer’s published information the SDE-265, SHDE-400 and SHDE-4000 encoders and the HDD-275 decoder support SRT.
I do not know the model code. How do I get a quotation?
Send the sources, the number of channels, the destination of the streams and the viewing points; we will suggest the system.

- If you know the model: model code, quantity and delivery location are enough.
- If you do not: send the sources, the number of channels, the destination of the streams (LAN, internet) and the viewing points.
- If you have a specification or project drawing: send it and we will work out the matching models.
