The VIDEOCAST 3G-SDI 1×4 Splitter is a broadcast-grade SDI distribution amplifier used primarily in environments where a single SDI video source needs to be shared with multiple destinations — for example:
It takes a single 3G-SDI video input and replicates it across four outputs, while boosting and re-clocking the signal so that each output remains stable and clear over long coaxial cables. This is crucial in professional AV installations for live events, broadcast studios, control rooms, and multi-screen monitoring.
Key Specifications

VIDEOCAST 3G-SDI 1X4 Splitter Media Streaming Device
1. What does this device do?
Splits one SDI video input into four identical SDI outputs.2. What video formats does it support?
SD-SDI, HD-SDI and 3G-SDI (up to 1080p @60 Hz).3. Can the outputs show different content?
No — all outputs mirror the same signal.4. Does it convert to HDMI/USB?
No — this is only an SDI splitter; converters are separate.5. Do I need power?
Yes — it uses external DC power to boost and re-clock the signal.6. Will audio pass through?
Yes — embedded SDI audio is carried to all outputs.7. Is it suitable for live streaming/broadcast?
Yes — ideal for distributing SDI camera feeds to multiple monitors or encoders.
