Extron DSC 12G-HD A – 12G-SDI to HDMI Scaler with Stereo Audio

Product Overview

DSC 12G-HD A, part number 60-2061-01. The Extron DSC 12G-HD A is a 12G-SDI to HDMI scaler that converts multi-rate SDI signals into scaled HDMI for AV systems. It accepts 12G-SDI, 6G-SDI, 3G-SDI, and HD-SDI at data rates from 1.48 Gbps to 11.88 Gbps and outputs selectable rates from 640x480 through 4K/60, with custom output resolution support for non-standard displays. The Extron Vector 4K scaling engine handles the conversion, and logo image keying is available on the output. An SDI loop output passes the original signal through to downstream broadcast equipment.

Product Description

SDI and HDMI infrastructure coexist in more facilities than either camp likes to admit. Broadcast studios, houses of worship with production workflows, and university lecture capture systems all end up needing a camera or router output on an HDMI display, at a resolution the display actually accepts. A raw format converter gets the signal across but leaves scaling to the display, which is where image quality goes wrong.

The DSC 12G-HD A scales as well as converts. The Extron Vector 4K scaling engine takes any accepted SDI input and produces a selectable output rate from 640x480 up to 4K/60, with support for custom output resolutions where a display's native timing falls outside the standard list. Signal type support spans DVI 1.0, HDMI 1.4 and 2.0, and HD-SDI through 12G-SDI, with a maximum HDMI data rate of 18 Gbps and SDI at 11.88 Gbps.

Input handling covers one SDI input on female BNC with a loop output on a second BNC, at a nominal level of 0.8 Vp-p with no offset and an accepted range of 0.5 to 1.0 Vp-p. The loop output matters in production environments where the same camera feed has to continue to a switcher or recorder while a scaled copy goes to a confidence monitor or room display.

Chroma sampling supports 4:4:4 and 4:2:2, with 4:2:2 on the input side, and color bit depth is 8 or 10 bits per color with 10-bit accepted on input. Frame rates of 24, 25, 30, 50, and 60 fps are supported. Logo image keying and display allows a station or institutional identifier to be composited on the output without a separate keyer. For the reverse direction, HDMI into multi-rate SDI, specify the Extron DSC HD-12G A.

Key Features

• Multi-rate SDI input — Accepts 12G-SDI, 6G-SDI, 3G-SDI, and HD-SDI at data rates from 1.48 Gbps to 11.88 Gbps.
• Extron Vector 4K scaling — The Vector 4K scaling engine converts any accepted input to a clean, selectable output rate.
• Selectable output rates — Output resolutions from 640x480 to 4K/60, with custom output resolution support for non-standard displays.
• SDI loop output — Passes the original SDI signal through on a second BNC so the feed continues to a switcher or recorder.
• Logo image keying — Composites a logo or identifier onto the output without requiring a separate keyer.
• Stereo audio support — Handles stereo audio alongside the video conversion for complete signal delivery.
• Broadcast-standard connectors — Two female BNC connectors at 0.8 Vp-p nominal with a 0.5 to 1.0 Vp-p accepted range.
• Wide frame rate support — Supports 24, 25, 30, 50, and 60 fps for film, broadcast, and computer source material.

Frequently Asked Questions

What is the difference between converting and scaling?

A converter changes the signal format but passes the resolution through, leaving the display to scale it. The DSC 12G-HD A scales in the box using the Extron Vector 4K engine, so you control the output resolution and get consistent image quality regardless of what the display's internal scaler would have done.

Which SDI rates are supported?

12G-SDI, 6G-SDI, 3G-SDI, and HD-SDI, covering data rates from 1.48 Gbps to 11.88 Gbps. The unit auto-handles the accepted rates on its single SDI input.

What does the loop output do?

It passes the original, unmodified SDI signal to a second BNC so the same camera or router feed can continue to a production switcher or recorder while the scaled HDMI copy feeds a display.

Can I output a non-standard resolution?

Yes. In addition to the selectable standard rates from 640x480 to 4K/60, the scaler supports custom output resolutions for displays and LED processors with non-standard native timings.

Does it handle 4:4:4 chroma?

4:4:4 and 4:2:2 are supported, with 4:2:2 on the input side. Color bit depth is 8 or 10 bits per color, with 10-bit accepted on input.

What if I need the opposite direction?

The Extron DSC HD-12G A converts HDMI into multi-rate SDI with two mirrored SDI outputs. The two products are often specified together in facilities that bridge both directions.

What support is available for integration?

Creation Networks can review the SDI and HDMI signal path, confirm output resolution requirements against the display, and coordinate Extron warranty and RMA handling.
