 DSC 3G-HD A 3G-SDI to HDMI Scaler 60-1303-01

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

High Performance Video Processing

The DSC 3G‑HD A provides high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. Additionally, the color space and chroma subsampling of the HDMI output can be automatically set to ensure compatibility with a connected DVI or HDMI display. Automatic 3:2 and 2:2 pulldown detection maximizes image quality for content sources originating from film.

To enhance and simplify integration, the DSC 3G‑HD A offers automatic input equalization and reclocking on the buffered SDI loop-through. Input equalization restores and reshapes incoming 3G‑SDI 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 3G‑HD A offers enhanced audio capabilities, including HDMI 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 up to four pairs of AES audio channels from the SDI input onto the HDMI output. The DSC 3G‑HD 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 3G‑HD 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 3G‑HD A is housed in a 1U, half rack width metal enclosure and can be easily integrated into a variety of environments.
