Introduction

This manual contains information about the Extron® DVS 304 Series of scalers with

instructions for experienced installers on how to install, conﬁgure, and operate the equipment.

In this manual the terms “DVS,” “digital video scaler,” and “scaler” are used interchangeably and refer to any DVS 304 Series model.

DVS 304 Series Description

The DVS 304 Series of digital video scalers is comprised of DVS 304 and DVS 304 DVI

models

• DVS 304, DVS 304 D, DVS 304 A, and DVS 304 AD

• DVS 304 DVI, DVS 304 DVI D, DVS 304 DVI A, and DVS 304 DVI AD

They are available as half rack, non-audio models or full rack size models with balanced/ unbalanced audio.

• Half rack: DVS 304, DVS 304 D, DVS 304 DVI, DVS 304 DVI D

• Full rack: DVS 304 A, DVS 304 AD, DVS 304 DVI A, and DVS 304 AD:

All models are 4-input, 1-output, high performance RGB and video scalers, providing

scaling solutions for boardrooms, conference rooms, and home theaters, as well as

rental and staging applications. The DVS 304 series scales from composite video, S-video, component (Y, R-Y, B-Y) video, and RGB video to computer-video (RGBHV/RGBS/RGsB) or HD component.

The four inputs of all DVS models accommodate composite video, S-video, component video, and RGB. The fourth input is fully congurable to accept any available analog video format from composite video to RGBHV. Additionally, with the exclusive Auto Input Format Detection mode, the DVS 304 devices automatically detect and then process the incoming

signal format to this input.

The DVS 304 Series audio models offer four input audio switching for stereo unbalanced

or balanced sources, with gain and attenuation controls available for each input. All audio connections are on captive screw connectors for ease of integration, and output volume

control eliminates the need for a separate audio preamplier in many A/V systems.

DVS 304 Models

On these models, two identical, scaled outputs are available on 15-pin HD and BNC connectors. A total of 69 output scan rates are available from VGA (640x480) to UXGA (1600x1200) resolution, as well as HDTV at 720p, 1080i, and 1080p/60 Hz.

NOTE: See the Resolution and Refresh Rate table in the Operation section, page 15,

for a comprehensive list.

DVS 304 Series • Introduction 1

DVS 304 DVI Models

Features

The DVS 304 DVI offers simultaneous digital and analog scaled outputs through the DVI-I port. Simultaneous analog scaled output is also available on BNC connectors. A total of 70 output scan rates are available from VGA (640x480) to WUXGA (1920x1200) resolution, as well as HDTV at 720p, 1080i, and 1080p/60 Hz.

In addition the DVS 304 DVI features EDID Minder, which enables automatic and continuous management of the EDID information between the computer-video input

source and the display, ensuring that the source powers up properly and reliably outputs content to the display.

Four inputs —

• Input 1 – One BNC connector accepts composite video.

• Input 2 – Three BNC connectors accept composite video, S-video, or component

video.

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

• Input 4 – A 15-pin HD connector accepts an RGB, component video, S-video, or

composite video signal.

• SDI video input (optional) – One BNC connector accepts SDI video. During setup, the

SDI input is assigned to input 1, 2, 3, or 4 (the default is none).

RGB and video scaling — Provides a high performance scaling engine with the capacity to scale standard deﬁnition video, high deﬁnition video, and computer-video signals up or down in resolution.

Picture control — Allows size, position, brightness, contrast, color, tint, detail, zoom and pan adjustments for each input.

Picture-In-Picture — Allows for a low resolution (YUVi, S-video, composite video, and SDI) input and a high resolution (VGA and YUVp/HDTV) input to be displayed

simultaneously.

Memory and input presets — Memory presets save sizing, positioning, and picture control settings.

Input presets (on input 4 only) save input conguration, picture control, and OSD (on-screen display) text.

Auto-Image™ — Auto-Image automatically sizes, centers, and optimizes the image to that of the scaled output rate, ﬁlling the window with the image.

IP Link® — IP Link-enabled products offer an integrated Web server with high performance architecture, global compatibility with industry standard Ethernet communication protocols, multi-user support, and a Web-based asset management

application speciﬁcally designed to work with products that include IP Link technology.

DVS 304 Series • Introduction 2

Buffered video outputs —

• DVS 304 models – Five rear-panel BNC connectors and one VGA-type 15-pin HD

connector provide connections for RGB or Y, R-Y, B-Y output. Both outputs are active

at all times for simultaneous output.

• DVS 304 DVI models – Five rear-panel BNC connectors and one DVI-I connector

provide analog and digital output (DVI-I) and analog output (BNC). All outputs are active at all times for simultaneous output of RGB or Y, R-Y, B-Y. DVI-D output is disabled for RGB pass-though.

Device control — The scaler has four methods of control: by its front panel, via a

computer or other RS-232/Ethernet control device, using the optional IR 902 remote

control, or via the Signal Processing Products Control Program (SPPCP).

Scaled outputs — The DVS 304 models offer 69 output rates and the DVS 304 DVI models offer 70 output rates.

RS-232 conﬁguration — All DVS 304 series units can be congured by using the Extron control software for Windows® or by using a control system.

Front panel security lockout (executive mode) — To prevent accidental changes to the unit’s settings, the scaler provides front panel lockout of all controls except input switching. A second executive mode completely disables all front panel controls.

3:2 pull down detection for NTSC and 2:2 ﬁlm detection for PAL video sources — These patented, advanced ﬁlm mode processing features help maximize image detail

and sharpness for video sources that originated from lm. When lm is converted to

NTSC video, the ﬁlm frame rate has to be matched to the video frame rate in a process

called 3:2 pull down. “Jaggies” and other image artifacts can result if conventional de-

interlacing techniques are used on ﬁlm-source video. The digital video scaler’s advanced ﬁlm mode processing recognizes signals that originated from ﬁlm. The scaler then applies video processing algorithms that optimize the conversion of video that was made with the

3:2 pull down process. This results in richly detailed images with sharply dened lines. A

similar process is used for PAL ﬁlm-source video.

Versatile mounting options — The non audio models are 1U high, half rack wide rack

mountable devices. Alternatively, they can be placed on a table or other furniture. Rubber feet are included.

The audio models are 1U high and full rack size and can be rack or desk mounted using

included rack or through-desk mounting brackets.

Controlling the DVS 304 Devices

All DVS 304 series devices 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 or Ethernet port. The Extron Simple

Instruction Set (SIS™) is a set of simple keystroke commands that can be used with any

such devices, and Extron control software for Windows provides a graphical interface

for controlling the scaler from a computer.

• The optional IR 902 remote control, replicating most of the front panel controls.

• Ethernet control via IP Link, enabling the scaler to be controlled and actively monitored

over a LAN, WAN, or the Internet.

DVS 304 Series • Introduction 3

Options and Accessories

The DVS 304 series optional equipment includes:

• IR 902 remote control — The Extron IR 902 (part #70-495-01) is an infrared remote

control that replicates most of the front panel controls of the digital video scaler (except the Menu and Next buttons).

• SDI input card — Serial digital interface (SDI) input can be added to a DVS 304 model

by the installation of an SDI input card (part #70-168-01).

Remote (RS-232/contact closure) port — This 9-pin connector provides for two-

way RS-232 communication. See the “SIS Communication and Control” chapter 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 Ground Signal ground 6 Input 3 Contact closure

7 Input 4 Contact closure 8 - No connection

9 - Reserved

Figure 7. RS-232 Pin-out

The Remote connector also provides a way to select an input using a remote contact

closure device. Contact closure control uses pins on the RS-232 connector that are not used by the RS-232 interface (see preceding table).

To select a different input number using a contact closure device, short the pin for the desired input number to logic ground (pin 5).

NOTE: If contact closure is not in use, pins 1, 4, 6, and 7 should have no

connection.

Start Auto Image

Auto image an input to “auto size” and “auto center” the image to ll the screen. The

processor measures the sync frequencies from incoming video sources and uses an internal table to set the active image area, total image area, and the sampling frequency.

If an unknown input is connected to the unit, the processor measures and estimates the resolution of the incoming video.

The DVS 304 can be set to automatically auto-image newly detected inputs (see page 21).

DVS 304 Series • Operation 18

Auto-Image

™

When enabled and a new input frequency is detected, the DVS rst applies an existing

Auto Memory for the signal (if Auto Memory is enabled), or if no entry exists, performs an automatic Auto-Image on the new signal.

With Auto Image disabled, the DVS 304 will apply default values to a new input if no Auto Memory exists (if Auto Memory is enabled). Default is Off.

See the table on page 21 for a full description of the interaction between the Auto-Image and Auto Memory settings.

NOTE: An input with a vertical refresh rate less than 40 Hz must be manually centered

and sized using H/V Start and H/V Active under the Input Cong menu. When a rate with a low vertical refresh rate (for example 720p 29.9 Hz) is applied and an Auto Image command is issued, the DVS 304 refers to the default values

instead of performing a true Auto-Image.

Blue mode

The Blue mode assists the user in setting up a scaler’s color and tint level. To use this feature, set this submenu to “On” so that only sync and blue video signals will be passed

to the display.

Use either the Adjust horizontal ([) or Adjust vertical ({) knob to select this mode. The default state is “Off”.

NOTE: The Blue mode has no effect for RGB pass-through mode on Input 4.

Auto switch mode

The Auto switch mode causes the highest numbered input having a signal present to be

automatically selected. For example, if both inputs 1 and 3 have active input signals, input 3 will be selected.

From this submenu, use either the Adjust horizontal ([) or Adjust vertical ({) knob to

specify this mode as “On” or “Off.” The default is “Off.”

NOTE: The Auto switch mode ignores the presence of an SDI input signal, so any input

that is assigned an active SDI signal will not be selected.

RGB delay

The RGB delay feature applies a brief delay before displaying a new picture to a screen and

allows the display device to adjust to the new sync timing. This feature provides

“no-glitch” switching. The blanking period can be set from 0 to 5 seconds in 0.5 second

steps.

DVS 304 Series • Operation 19

OSD label

Use the On-Screen Display (OSD) label menu to determine the time allotment for an input

label or a user deﬁned OSD label. Input labels are generic labels shown for inputs 1, 2

and 3. For input 4, the user can create a custom OSD label to display.

The OSD labels are displayed (white box, black text) in the top left corner.

The OSD label can be turned off by setting its duration to Off from the Advanced Conﬁguration menu.

For OSD text, note the following:

• Line 1 displays the input number.

• Line 2 displays the input type.

• Line 3 displays a text label that you can dene (input 4 only).

The display time can be set from 0 to 5 seconds in 1 second steps (default is 2 seconds).

Test pattern

Test patterns are useful for calibrating a display to the DVS 304 output. Choose a test

pattern to adjust the image using built in crop, alternating pixels, and color bars.

NOTE: • Alt Pixels — Used to calibrate display devices input sampling to the

DVS 304’s output. Use this pattern to adjust the clocking and phasing at the

display until no more vertical bands are visible.

• Crop — Used to center the DVS 304’s output on the display device: adjust H and V center on the display until all four crop lines are visible.

• Color Bars — Used to calibrate color settings on the display and to conrm proper system wiring.

Enhance mode

When the enhance mode is set to on, automatic gain control of the low resolution input

signal is enabled. If the input signal level is too weak, signal gain is increased, and if the input signal level is excessive, signal gain is decreased.

Using either the Adjust horizontal ([) or Adjust vertical ({) knob, select either On or Off as desired. The default is Off.

Refresh Lock

When Refresh Lock is enabled, the vertical output rate is locked to the current input’s

vertical refresh rate to prevent tearing and/or stuttering associated with frame conversion. This mode should be activated only when excessive stuttering and/or tearing is being experienced with an input signal.

Because the output’s vertical sync is linked to the current input’s vertical sync while in the

Refresh Lock mode, there may be a slight glitch in the output sync whenever a new source is applied to the scaler, or whenever a new input is selected. This is caused by the scaler instantly locking its refresh rate to that of the new input signal.

NOTE: The output refresh rate must be set equal to or greater than the incoming

video’s refresh rate or no video output will be displayed. If the incoming video’s vertical rate differs signiﬁcantly from the set output refresh rate, no video will be displayed.

DVS 304 Series • Operation 20

Auto Memory

The DVS 304 stores 16 auto memories with input and picture control data for each input.

The default settings enables these memories to automatically recall input and picture

controls for signals that have been previously applied. By disabling auto memories, the DVS 304 will treat every newly applied input as a new source. Default is on.

Aspect Mode

The aspect mode setting is global, and allows the user to select between each input signal ﬁlling the entire output raster (Fill), or for each input rate to be displayed with its native aspect ratio (Follow - default setting).

When in the Fill mode, if an aspect ratio adjustment for a single input rate is desired, the desired setting (4x3 or 16x9) can be made in the input cong menu by adjusting the

aspect ratio setting. If auto memories is enabled, then this setting is saved and recalled the next time the signal is detected.

It is strongly recommended that the aspect ratio mode setting be used on initial setup of

the DVS, or input rates that have not already been saved as auto memories may not be

displayed as expected. This can be overcome by clearing the auto memories on the input in question, and is done by holding in the front panel Menu button and the applicable input button simultaneously for four seconds. Alternatively it can be cleared on a rate by rate basis by applying a one time auto image.

DVS 304 Series • Operation 21

Picture-in-picture mode

The DVS 304 can display two image sources on the screen simultaneously. Keep in mind

that when using the PIP feature, one image source must be low-resolution (composite,

S-video, YUVi and RGBcvS) video, while the other must be high resolution (YUVp/HDTV, RGB scaled, SDI) video. If these conditions are not met (for example, two low resolution

video inputs or two high resolution inputs are selected), the PIP mode will exit.

To go into picture-in-picture mode, do the following:

1. Select an input for the main window.

2. Deﬁne the size of the main window before starting PIP mode.

3. Activate the PIP mode via an SIS command or IR remote; specify the PIP window input.

DVS 304 checks the input format for the PIP window and returns an error message if an

invalid selection is made.

NOTE: For quick sizing setup, use the 16*# X10% SIS command to set different sizes for

the PIP window.

When the PIP mode is active, note the following:

• The LED for the main window input is ON.

• The parameters of the PIP window are adjustable from the front panel or by SIS

commands only.

• Any change in conﬁguration (except positioning) of the PIP window is saved to that

input even after the PIP mode is not longer active.

• The PIP window input is listed under the default cycle on front panel menu, as shown

below.

When the PIP window is active, size, position, and picture controls all apply to the PIP

window. The main window settings cannot be modiﬁed while the PIP window is active. The PIP size and position can be adjusted with the same front panel controls or SIS commands used to adjust the main image.

If the PIP window source is not active, the PIP mode exits until an active signal is detected.

When the main window source is removed, a black background is displayed.

Changing the input

To change the input for the PIP and/or main window, determine if the corresponding input is a low or high resolution.

If your main window image is from a low resolution source, switch to another low resolution input from the front panel.

Using the swap feature

Use the swap feature to switch the active main window input with the current PIP input. For example if the main window is Input 4 (RGB scaled) and the PIP window is Input 1

(composite), applying the swap command results in Input 1 becoming the main window

and Input 4 the PIP window.

For audio models (DVS 304 A, DVS 304 AD, DVS 304 DVI A, and DVS 304 DVI AD), you

can set audio to follow the main (default) or PIP window. Audio breakaway is not possible

while PIP mode is on; audio must follow either the main window or the PIP window.

From this submenu, press the Menu button to return to the Start Auto Image menu cycle, or press the Next button to return to the default cycle.
