DSC HD-3G A	HDMI to 3G-SDI Scaler	60-1304-01

The Extron DSC HD‑3G A is a high performance HDMI to 3G‑SDI scaler that converts HDMI video signals to 3G‑SDI, HD‑SDI, and SDI formats. It accepts computer and SMPTE video resolutions up to 1920x1200 and 2K, and offers multiple output rates from 480i and 576i up to 1080p/60 and 2K. The DSC HD‑3G A features advanced Extron video signal processing with deinterlacing of signals up to 1080i, and Deep Color processing. Dual SDI outputs, stereo audio embedding, and genlock facilitate integration in demanding professional environments, while the compact enclosure simplifies installation. The DSC HD‑3G A is ideal for applications requiring professional or consumer-level equipment to be interfaced with broadcast-type signals, including video editing and production, rental and staging, medical imaging, and large-scale presentations.

High Performance Video Processing

The DSC HD-3G A provides high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. Automatic 3:2 and 2:2 pulldown detection maximizes image quality for content sources originating from film. In addition, the DSC HD-3G A provides two simultaneous 3G-SDI/HD-SDI/SDI outputs so that two displays can be driven simultaneously, without the need for additional equipment.

To enhance and simplify integration, the DSC HD-3G A offers automatic input cable equalization. Input equalization restores and reshapes incoming HDMI signals, reducing the need for additional signal conditioning equipment by compensating for weak source signals or signal loss from a long input cable.

Selectable FILL and FOLLOW modes are also available to ensure the proper aspect ratio of the output. FILL mode provides full screen output, while FOLLOW mode preserves the original aspect ratio of the input signal.

Enhanced Audio Capabilities

The DSC HD-3G A offers enhanced audio capabilities, including SDI audio embedding, input gain and attenuation controls, and input audio muting. To suit the needs of the application, the scaler can embed analog input audio signals or HDMI multi-channel PCM audio onto the SDI outputs. The DSC HD-3G A provides gain and attenuation adjustments for the analog stereo input, as well as the ability to mute the audio input.

Multiple Options for Control and Operation

The DSC HD-3G A features front panel controls for quick access to functions. Remote configuration and control are available via RS-232 and USB. The on-screen menus provide control over the unit's functions and settings, including quick access to key parameters such as input and output video formats and resolutions. Additionally, LED indicators on the front panel provide visual confirmation of input and output signal format, and signal presence. The DSC HD-3G A is housed in a 1U, half rack width metal enclosure and can be easily integrated into a variety of environments.

Features

HDMI to 3G‑SDI, HD‑SDI, and SDI video scaling — The DSC HD‑3G A provides high quality conversion of signal format and video resolution with audio embedding.

Inputs: One HDMI, balanced/unbalanced stereo on 5‑pole captive screw

Outputs: Dual buffered 3G‑SDI/HD‑SDI/SDI on BNC

Accepts HDMI signals up to 1920x1200, 1080p/60, and 2K — The DSC HD‑3G A accepts HDMI input signals at a variety of resolutions. Only unencrypted content can be sent to the output.

Two simultaneous 3G‑SDI/HD‑SDI/SDI outputs — Simultaneous 3G‑SDI/HD‑SDI/SDI outputs are available for driving two displays.

Advanced scaling engine with 30‑bit precision processing and motion-adaptive deinterlacing for signals up to 1080i — Image scaling and video format conversion are performed at 30‑bit precision for enhanced color accuracy and picture detail. Advanced deinterlacing for all interlaced signals up to 1080i delivers optimized image quality.

SDI audio embedding — Analog stereo audio or HDMI multi‑channel PCM audio can be embedded onto the SDI outputs.

Selectable output rates from 480i and 576i to 1080p/60 and 2K — Available output rates include 480i, 576i, rates up to 1080p/60, and 2K. The DSC HD‑3G A complies with SMPTE 259M, 292M, 424M, and ITU digital video standards.

Aspect ratio control — The aspect ratio of the video output can be controlled by selecting a FILL mode, which provides a full screen output, or a FOLLOW mode, which preserves the original aspect ratio of the input signal.

EDID Emulation provides selectable resolutions and refresh rates to ensure reliable operation — The DSC HD‑3G A provides a means for specifying the rate of the incoming signal, ensuring proper communication with the video source.

Genlock input with loop-through — Allows for synchronization to an external reference signal and supports bi‑level or tri‑level sync for integration into broadcast and production applications.

AFL™ - Accu‑RATE Frame Lock — A patented technology exclusive to Extron that locks the output frame rate to the input to eliminate stuttering caused by frame rate conversion.

Front panel LED indicators for signal format, presence, and power — Provides visual indication of system status for real-time feedback and monitoring of key performance parameters.

Image freeze control — A live image can be frozen using RS‑232 serial control or USB.

Auto Input Memory — When activated, the unit automatically stores size, position, and picture settings based on the incoming signal. When the same signal is detected again, these image settings are automatically recalled from memory.

Selectable output color space — The color space can be set to RGB or component video.

On‑screen menus — Intuitive on‑screen menus allow for easy system setup using the front panel controls. Key parameters such as input and output video formats are conveniently grouped on the initial Quick Setup screen, while additional screens provide full control over the unit's other functions and settings.

Output Standby Mode — The unit can be set to automatically mute video and sync output to the display device when no active input signal is detected. This allows the projector or flat-panel display to automatically enter into standby mode to save energy and enhance lamp or panel life.

Power Save Mode — The unit can be placed in a low power standby state to conserve energy when not in use.

Automatic 3:2 and 2:2 pulldown detection — Advanced film mode processing techniques that help maximize image quality for NTSC, PAL, and 1080i sources that originated from film.

Picture controls for brightness, contrast, and detail, as well as horizontal and vertical positioning, overscan, and sizing

User presets — Memory presets are available for each input to store and recall optimized image settings.

Internal video test patterns and pink noise generator for calibration and setup — The unit offers several video test patterns and audio pink noise to facilitate proper system setup and calibration of display devices.

Automatic input cable equalization — Actively conditions incoming HDMI signals to compensate for signal loss when using long cables, low quality cables, or source devices with poor signal output.

Audio input gain and attenuation — Gain and attenuation can be adjusted for the analog stereo input.

Integrated audio delay — The audio output is automatically delayed to compensate for latency introduced by the video processing.

Input audio muting — The analog stereo or HDMI audio input can be individually muted.

Front panel security lockout — This feature locks out all front panel functions; all functions however, are available through USB or RS‑232 control.

RS‑232 control port — Enables the use of serial commands for integration into a control system. Extron products use the SIS™ - Simple Instruction Set command protocol, a set of basic ASCII code commands that allow for quick and easy programming.

Front panel USB configuration port — Enables easy configuration without having to access the rear panel.

Easy setup and commissioning with Extron's PCS - Product Configuration Software — Conveniently configure multiple products using a single software application.

1U, half rack width metal enclosure

Includes LockIt^® cable lacing brackets — Securely fastens HDMI or USB‑C^® cables to a device, eliminating risk of disconnection.
