Introduction
About this Manual
This manual discusses how to install, configure, and operate the Extron DVS 204
digital video scaler and how to operate the optional IR 901 infrared remote
control (part #70-152-01).
Throughout this manual the terms “DVS”, “digital video scaler”, and “scaler”
are used interchangeably to refer to the same product.
About the DVS 204
What is the DVS 204?
The DVS is a series of high performance digital video scalers that offers 56
output rates, including HDTV, and provides scaling solutions for boardrooms,
conference rooms, and home theaters, as well as rental and staging applications.
The scalers come in four models, two of which offer a serial digital interface (SDI)
input connector: DVS 204 (no SDI), DVS 204 D (SDI), DVS 204 12V (12 volt
external power supply, no SDI), and DVS 204 D 12V (12 volt external power
supply, SDI).
To enable superior scaling performance, the DVS 204 features several of Extron’s
patented and patent-pending technologies, including Dynamic Motion
Interpolation (DMI™) technology, and 3:2 and 2:2 pulldown detection. DMI is
an advanced motion detection and compensation method that enables image
enhancement with no loss of image fidelity.
The DVS 204 scales composite video, S-video, and component video up to
computer-video (RGBHV/RGBS/RGsB) or HD component, which can be output
to two display devices via individually buffered BNC and 15-pin HD connectors.
Controlling the DVS 204 digital video scaler
The DVS 204 can be controlled using one or more of the following methods:
• The front panel controls.
• A computer, a touch screen panel, or any other device that can send and
receive the serial communications through the RS-232 port. Extron’s
Simple Instruction Set (SIS
™
) is a set of simple keystroke commands that
can be used with any such devices, and Extron’s control software for
Windows provides a graphical interface for controlling the scaler from a
computer.
• The optional IR 901 remote control, which has most of the front panel controls.
