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.

Features and Options

Features

Four video inputs

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

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

•Inputs 3 — One 4-pin DIN connector accepts an S-video signal.

•Input 4 — One 15-pin HD connector accepts an RGB pass-through (RGBHV, RGBS, RGsB), RGBS, or RGBcvS video signal.

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

1-2 DVS 204 • Introduction

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.

Three ways to control the scaler — The scaler’s front panel, a computer or other RS-232 control device, or the optional IR 901 remote control can all be used to control the scaler.

Scaled outputs — The DVS 204 offers 59 different output rates.

RS-232 configuration — The DVS 204 can be configured by using the Extron control software for Windows, or by using a third party control system.

Accu-RATE Frame Lock™ — The Extron Accu-RATE Frame Lock™ eliminates artifacts from scaled motion video by eliminating frame rate conversion. It locks the output frame rate to the input frame rate of the active input. The result is a switching system that eliminates image tears and other artifacts from motion video.

Dynamic Motion Interpolation™ (DMI™) — This video processing technique is an advanced motion prediction and compensation method that treats motion content and still content with different algorithms to yield high fidelity images.

3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources

— These advanced film mode processing features help maximize image detail and sharpness for video sources that originated from film. When film is converted to NTSC video, the film frame rate has to be matched to the video frame rate in a process called 3:2 pulldown. Jaggies and other image artifacts can result if conventional deinterlacing techniques are used on film-source video. The DVS 204’s advanced film mode processing recognizes signals that originated from film. The DVS 204 then applies video processing algorithms that optimize the conversion of video that was made with the 3:2 pulldown process. This results in richly detailed images with sharply defined lines. A similar process is used for PAL film-source video.

Versatile mounting options — The DVS 204 is 1U high, and a half rack wide. It is rack mountable, or it can be placed on a table or other furniture. Rubber feet are included.

Options and accessories

The DVS 204’s optional equipment includes:

•IR 901 remote control — Extron’s IR 901 (part #70-152-01) is an infrared remote control which replicates all of the front panel controls of the DVS 204 except the Menu and Next buttons.

•SDI input card — Serial digital interface (SDI) input can be added to the DVS 204 model by the installation of an SDI input card (part #70-168-01).

•Rack shelf mounting kit — The 1U high, half rack width DVS 204 can be rack mounted using the rack shelf mounting kit (part #60-190-01).

	RGsB	Component Video (R-Y, Y, B-Y)
	Outputs 7 and 8	are both buffered and can be connected simultaneously

to two different displays. For RGB inputs, the output signal’s sync format is based on the format of the incoming RGB signal. For all other types of inputs, the user selects the output sync format. The sync format will be the same for both outputs.

RGB pass-through — An RGB pass-through signal with composite sync (“RGB” is selected for input 4; see the Input Configuration section in this chapter) will always output composite sync through the “H” BNC output connector, as shown in the following illustration.

If both an RGB pass-through signal with composite sync and a scaled video input (1-3) are output as RGBS, the H Format must be set to “HV” (composite sync). This will cause the scaled video input to output composite sync on the same connector (the “H” BNC) as the pass-through signal instead of the “S” BNC. See the H Format section in this chapter.

For scaled inputs on input 4 (RGBS or RGBcvS), the H Format will not have to be set to “HV” since those inputs will be output like inputs 1-3, as shown in the previous connection diagram.

8RGB or HD component (R-Y, Y, B-Y) 15-pin HD video output — Connect an RGB video display or HD component video display to this connector.

9Remote (RS-232/contact closure) 9-pin port — This connector provides for two-way RS-232 communication and contact closure control. See chapter three, “Serial Communication”, for information on how to install and use the control software and SIS commands.

The default protocol is 9600 baud, 1 stop bit, no parity, and no flow control.

The rear panel RS-232 9-pin D female connector has the following pin assignments:

Pin	RS-232 function	Description
1	Input #1	Contact closure
2	Tx	Transmit data
3	Rx	Receive data
4	Input #2	Contact closure
5	Gnd	Signal ground
6	Input #3	Contact closure
7	Input #4	Contact closure
8	–	No connection
9	Hardwired IR	IR input

The Remote connector also provides a way to select an input using a remote contact closure device. Contact closure control uses pins on the Remote connector that are not used by the RS-232 interface (see preceding table).

To select a different input number using a contact closure device, momentarily short the pin for the desired input number to logic ground (pin 5). To force one of the inputs to be always selected, leave the short to logic ground in place. The short overrides front panel input selections.
