Introduction
This guide contains information about the Extron DSC 301 HD Digital Scaling Converter
with instructions on how to install, configure, and operate the equipment.
In this guide the terms digital scaler and scaler are used interchangeably and refer to the
DSC 301 HD scaler.
This section gives a basic description and the key features of the DSC 301 HD scaler.

DSC 301 HD Description
The DSC 301 HD is a 1-inch high, half rack wide, three input, HDCP-compliant video
scaler that includes an HDMI input, configurable high resolution analog, and composite
video inputs, and a single 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 1080i deinterlacing, EDID Minder, Key Minder, and automatic input
switching. Audio from any of three stereo inputs may be embedded onto the HDMI
output. Front panel controls, an intuitive on-screen display, plus USB and RS-232
connections provide flexible control and monitoring.
The unit can be rack mounted or installed under a desk using the optional MBU 125 rack
mounting brackets.
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 HDTV 1080p/60 and
2048x1080. The DSC 301 HD also features Deep Color processing and high performance
deinterlacing of 1080i to deliver optimal image quality through advanced motion
compensation. 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.
Output scan rates are available from VGA (640x480) to 1920x1200 resolution, as well as
HDTV at 720p, 1080i, 1080p/60 Hz, and 2k/60 Hz.
NOTE: See the Resolutions and Refresh Rates table on page 20 for a complete
list.
The DSC 301 HD features automatic 3:2 and 2:2 pulldown detection, which maximizes
the image detail and sharpness for content sources originating from film. The scaler also
uses a digital 3D adaptive comb filter that optimizes decoding of NTSC, PAL, and SECAM
sources for integration into systems worldwide.
DSC 301 HD • Introduction 1

Key Features
Inputs
• Video — The DSC 301 HD has the following connectors: one HDMI connector,
one 15-pin HD connector for RGBHV or HD/SD component video, and one BNC
connector for composite video.
• Auto-Image setup — When activated, the unit automatically detects the resolution
of the incoming video signal and sets the total pixels, phase, active pixels, and active
lines, as well as the horizontal and vertical starting points.
• Auto Input memory — When activated, the unit automatically saves input sampling
and picture settings based on the incoming signal. When the same signal is detected
again, these image settings are automatically recalled from memory.
• Auto-switching between inputs — Auto-switching allows for simple, unmanaged
installation in locations such as in a lectern or under a conference table. When
multiple inputs are active, the switching priority is configurable.
• HDMI, RGB, HDTV, and video scaling to HDMI — Digital and analog video sources
can all be scaled to high resolution HDMI output.
• Clean switching — Clean cut through black and fade through black transition
effects are available to enhance presentations by eliminating distractions during input
switching.
• Audio — The DSC 301 HD has the following connectors: three 3.5 mm stereo mini
jacks for analog audio input, and an embedded HDMI digital audio input.
• HDMI audio embedding — Analog input audio signals can be embedded onto the
HDMI output signal.
• Audio input gain and attenuation — Gain or attenuation can be adjusted for each
analog audio input to eliminate noticeable differences when switching between
sources.
• Audio input assignment — Each video input can be assigned to any analog audio
input. This enables all three video inputs to share a single analog audio input. The
HDMI input can be set to pass incoming digital audio, embed the analog audio, or to
automatically embed the analog audio when no digital audio is detected.
Outputs
• Video and Audio — The DSC 301 HD has one HDMI output.
• Selectable output — Available output rates include computer-video 640x480 up to
1920x1200, HDTV rates up to 1080p/60, and 2048x1080.
• Output Standby Mode — 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.
• 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.
• HDCP authentication and signal presence confirmation — Provides real-time
verification of HDCP status for each digital video input and output. This allows for
simple, quick, and easy signal and HDCP verification through front panel LEDs or
RS-232, providing valuable feedback to a system operator or helpdesk support staff.
