DSC 301 HD Three Input HDCP-Compliant Scaler 60-1253-01

The Extron DSC 301 HD is a three input, HDCP‑compliant video scaler that includes an HDMI input, configurable high resolution analog and composite video inputs, and an HDMI output. The DSC 301 HD accepts a wide variety of video formats including HDMI, HDTV, RGB, component, and standard definition video. It features advanced Extron video signal processing with deinterlacing of signals up to 1080i. The DSC 301 HD includes many integrator-friendly features including EDID Minder® and automatic input switching. Analog audio from any of three stereo inputs may be embedded onto the HDMI output. Front panel controls, intuitive on-screen menus, plus USB and RS‑232 connections provide flexible control and monitoring. The compact, low profile, half‑rack width enclosure of the DSC 301 HD enables simple and discreet mounting in many environments.

EDID Minder and Key Minder

To enhance and simplify integration of sources and displays, the DSC 301 HD features two exclusive Extron technologies: EDID Minder and Key Minder®. EDID Minder manages EDID communication between the display device and input sources. For HDMI signals with protected content, Key Minder authenticates and maintains continuous HDCP encryption between input sources and displays to ensure quick and reliable switching.

When receiving an HDCP-encrypted HDMI input source signal, the DSC 301 HD outputs a full-screen green signal on any video output connected to a non-HDCP compliant display. This provides immediate visual confirmation that the protected content cannot be viewed on this display. In addition, the DSC 301 HD provides real-time verification of the HDCP status for the HDMI input and output, offering valuable feedback to system operators and helpdesk support staff.

High Performance Video Processing

The DSC 301 HD features advanced video processing with the ability to scale HDMI, HDTV, RGB, and standard definition video signals to a common high resolution output. It accepts and outputs signals up to 1920x1200, including 1080p/60 and 2K. The DSC 301 HD also provides high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. In addition, the color space and chroma subsampling of the HDMI output can be automatically set to ensure compatibility with a connected DVI or HDMI display.

The DSC 301 HD features automatic 3:2 and 2:2 pulldown detection, which maximizes image quality for content sources originating from film. The DSC 301 HD also uses a digital 3D adaptive comb filter that optimizes decoding of NTSC, PAL, and SECAM sources for integration into systems worldwide.

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 301 HD features HDMI audio embedding and flexible audio switching to accompany incoming video sources. Any input audio signal can be embedded onto the HDMI output for simplified system connections. In addition, the DSC 301 HD provides gain and attenuation adjustments for each analog input.

Multiple Options for Control and Operation

The DSC 301 HD features front panel controls for quick access to functions. Remote configuration and control are available via RS-232 and USB, plus easy-to-use on-screen menus. The on-screen menus provide full control over the unit's functions and settings, including quick access to key parameters such as input and output video formats and resolutions. The DSC 301 HD is housed in a 1" (2.5 cm) high, half rack width metal enclosure and can easily be integrated into a variety of environments.
