About the QSD 204

What is the QSD 204?

The QSD 204 is a high performance quad standard decoder.

The QSD 204 comes in two models, one of which offers a serial digital interface (SDI) input connector: QSD 204 (no SDI) and QSD 204 D (with SDI).

Controlling the QSD 204 quad standard decoder

The QSD 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 decoder from a computer.

•The optional IR 901 remote control, which has most of the front panel controls.

Features and Options

Features

Quad standard decoder — The QSD 204 converts interlaced S-video and composite video signals following either the NTSC 3.58, NTSC 4.43, PAL, or SECAM video standards, to a non-interlaced output: RGBHV, RGBS, RGsB, or component video.

Four video inputs —

•Input 1 — One BNC connector on the rear panel accepts composite video.

•Input 2 — Three BNC connectors on the rear panel accepts composite, component, or S-video.

•Input 3 — A 4-pin DIN connector accepts an S-video signal.

•Input 4 — A 15-pin HD connector accepts an RGBS or RGBcS video signal.

SDI video input (optional) — One BNC connector on the rear panel accepts SDI video.

Picture controls — Color, tint (hue), brightness, contrast, centering, and blanking. The blanking feature will remove unwanted scan lines from the top or bottom of a displayed image, such as noise and closed captioning.

Four-line adaptive comb filter — Separates the color carrier signal and it’s harmonics from the video signal to eliminate chroma noise and enables a projector or monitor to display a clean, clear picture.

Buffered video outputs — Six rear-panel BNC connectors and one VGA-type 15-pin HD connector provide connections for RGB output. Both outputs (the BNCs or the 15-pin HD connector) are active at all times for simultaneous output.
