HDMI to 3G HD/SD- SDI Converter
HDMI to SDI Converter will take nay HDMI source and convert it to 2 (dual) SD/HD-SDI(3G)
PN: H-HDMI-SDI
The HDMI to SD/HD-SDI converter allows you to take any HDMI signal conent and make it available to be dsiplayed on any SDI viewing device while maintaing max bit rate of 2.970G/s to give you highest supported resolution from your signal without any loss.
For PRO-DVB personnel this means that it is easier to convert your HDMI signal with audio to 3G SDI over longer cable runs
We also have SDI to HDMI converters : H-SDI-HDMI
How the Converter Works
The converter accepts a digital HDMI input signal and internally processes the video and audio streams into a professional Serial Digital Interface (SDI) signal format.
Supported formats typically include:
-
SD-SDI (270 Mbps)
-
HD-SDI (1.485 Gbps)
-
3G-SDI (2.97 Gbps)
This allows compatibility with nearly all professional broadcast equipment.
Once converted, the signal is transmitted through the BNC SDI output, which offers several advantages over HDMI:
• Much longer transmission distance
• Locking connector for professional reliability
• Broadcast-grade signal stability
• Compatibility with routers, patch panels, and distribution amplifiers
Real-World Applications
Broadcast Production
Many broadcast studios use HDMI cameras or computers for graphics, presentations, or streaming feeds. The HDMI-to-SDI converter allows these sources to integrate directly into an SDI production workflow.
Example workflow:
Camera → HDMI → Converter → SDI → Production Switcher
Live Event Production
At conferences, concerts, or corporate events, presentation computers usually output HDMI. The converter allows these signals to be distributed over long SDI cable runs to production equipment located far away.
Example:
Laptop → HDMI → Converter → SDI → Video Switcher → LED Wall
Fiber Video Transport
When transporting video across long distances, SDI is often converted to fiber optic signals.
Example signal chain:
HDMI Source
→ HDMI to SDI Converter
→ SDI Fiber Transmitter
→ Fiber Optic Cable
→ Fiber Receiver
→ Broadcast Equipment
This approach enables reliable kilometer-distance transmission without signal degradation.
RF and IPTV Systems
The converter is also frequently used in RF modulation and IPTV headend systems, where HDMI sources must be integrated into broadcast networks.
Example:
Media Player → HDMI → Converter → SDI → Encoder / RF Modulator → TV Distribution Network
This allows any HDMI device to become a broadcast television channel within a hotel, hospital, campus, or sports venue.
Key Advantages of SDI over HDMI
| Feature | HDMI | SDI |
|---|---|---|
| Connector | Consumer friction connector | Locking BNC |
| Distance | ~10–15 meters | Up to 100 meters or more |
| Broadcast compatibility | Limited | Industry standard |
| Signal stability | Consumer grade | Broadcast grade |
| Routing | Difficult | Easy through SDI routers |
Because of these advantages, SDI remains the preferred infrastructure in professional video environments.
