Vizrt NSP3GIO Spark Plus I/O 3G-SDI - FG-002866-R001

Product Overview

The Vizrt Spark Plus I/O 3G-SDI (FG-002866-R001) is a compact, bidirectional NDI-to-3G-SDI video converter supporting up to 1080p60. Powered entirely via Power over Ethernet, it requires only a single Ethernet cable for data, power, and video transport — making it one of the most deployment-friendly SDI-to-NDI converters available for broadcast and live production environments. Analog audio I/O and tally LED indicators are included, supporting direct integration into existing SDI broadcast infrastructure.

Product Description

The Spark Plus I/O 3G-SDI converts 3G/HD-SDI video to NDI for distribution across IP networks, and decodes NDI streams back to 3G-SDI output for SDI monitors, routing switchers, or downstream SDI equipment — all within a single compact unit. Video format support covers the full 3G/HD-SDI range up to 1080p60, with 75-ohm SDI impedance for proper termination in professional signal chains. Analog audio is handled via a 3.5mm line-level input for embedding and a 3.5mm output for de-embedding, providing a simple audio interface at the converter position. Program and Preview tally LEDs make it easy to confirm on-air and preview status without additional monitoring software. The web-based UI allows configuration and monitoring from any browser on the network. NDI virtual input compatibility extends interoperability to popular video conferencing and streaming applications including Zoom, Skype for Business, Teams, and Google Meet. For broadcast facilities, system integrators, and AV managers deploying NDI in environments with existing 3G-SDI infrastructure — legacy cameras, routers, multiviewers — the Spark Plus I/O 3G-SDI provides a direct, cost-effective conversion path without the need for local power outlets or additional cabling at each conversion point.

Key Features

• Bidirectional 3G-SDI and NDI Conversion — Single unit handles both SDI-to-NDI encode and NDI-to-SDI decode for flexible deployment.
• Power over Ethernet (PoE) — No external power supply — single Ethernet cable carries data and power to the converter.
• Up to 1080p60 Video — Full HD support across all 3G/HD-SDI formats including 1080i and 1080p60.
• 3.5mm Analog Audio I/O — Line-level audio embedding and de-embedding at the converter position.
• Program and Preview Tally LEDs — On-device LED indicators for on-air and preview status confirmation.
• Web-Based Configuration UI — Remote configuration and monitoring from any network-connected browser.
• NDI Virtual Input — Compatible with Zoom, Skype for Business, Teams, Google Meet, and other NDI-aware applications.
• NDI Multicast Support — Supports multicast mode for distributing NDI streams to multiple destinations simultaneously.

Typical Applications

• Connecting legacy 3G-SDI cameras to NDI production networks
• Adding NDI outputs to SDI routing switchers and multiviewers
• Fly-pack and mobile production NDI integration points

Frequently Asked Questions

Does the Spark Plus I/O 3G-SDI require a power supply?

No. It is powered entirely via Power over Ethernet (PoE). A PoE-capable switch or PoE injector is needed on the network side.

Can this converter work as both an encoder and a decoder?

Yes. A single FG-002866-R001 unit converts in both directions — 3G-SDI to NDI or NDI to 3G-SDI — configurable via the web UI.

Is it compatible with TriCaster systems?

Yes. The Spark Plus I/O 3G-SDI is fully compatible with TriCaster and 3Play NDI workflows as either an input source or output destination.

Does it support audio embedding and de-embedding?

Yes. The 3.5mm analog input embeds audio into the SDI or NDI stream; the 3.5mm analog output de-embeds audio from the incoming SDI signal.
