 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.
