The Extron DVS 304 DVI is a Video and RGB Scaler incorporating advanced scaling technology from Extron as well as a host of flexible, convenient, integrator-friendly features. This high performance scaler is designed to satisfy the requirements of today's high quality, high resolution video presentations using the latest displays, and at the same time facilitate the process of system integration. The DVS 304 DVI offers high performance video processing with selectable output rates up to 1920x1200 and HDTV 1080p/60, as well as simultaneous DVI and analog RGB or component video outputs. It is ideal for a wide range of AV environments including boardrooms, conference rooms, educational institutions, houses of worship, and event and staging applications.

High Performance RGB and Video Scaling

The DVS 304 DVI features a high performance scaling engine with the capability to scale standard definition video, high definition video, and computer-video signals up and/or down in resolution. With the DVS 304 DVI, only a single RGBHV connection to the display is required, resulting in cost savings due to reduced installation time, cabling, and system programming. The DVS 304 DVI also delivers glitch-free switching between video and computer-video sources. Offering the capability to process both conventional video and high resolution multimedia sources, the DVS 304 DVI creates a single, optimally scaled output to match the native resolution of the display.

Variety of Input Formats

The four inputs of the DVS 304 DVI accommodate composite video, S-video, component video, and RGB. SDI Serial Digital Interface input is available as an option. The fourth input is flexible and universal to accept any available analog video format from composite video to RGBHV. Additionally, with the exclusive Auto Input Format Detection mode, the DVS 304 DVI automatically detects and then processes the incoming signal format to this input. This powerful feature is particularly effective in simplifying system integration and operation when using a matrix switcher with the DVS 304 DVI.

EDID Minder

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. By maintaining continuous EDID communication, EDID Minder ensures that the source powers up properly and reliably outputs content to the display.

Multiple Control Options

The DVS 304 DVI can be operated via the front panel, RS-232, optional IR remote control, contact closure, and over a network. Ethernet control enables remote operation and configuration, monitoring of critical functions, and management of any equipped product throughout a facility from any Ethernet connection. With the DVS 304 DVI, Ethernet control also allows for direct communication with Extron Ethernet-enabled matrix switchers for quick interoperation and powerful system integration.

Digital and Analog Scaled Outputs

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. Selectable output rates are available from VGA (640x480) to WUXGA (1920x1200) resolution, as well as HDTV at 720p, 1080i, and 1080p/60.

Audio Models Available

The DVS 304 DVI A and DVS 304 DVI AD offer four input audio switching for stereo unbalanced or balanced sources. Independent gain and attenuation controls are available for each input, and all audio connections are on captive screw connectors for ease of integration. The output volume control eliminates the need for a separate audio preamplifier in many AV systems.

Integrator Friendly Features

The DVS 304 DVI is equipped with a comprehensive feature set for integrator friendly access and configuration, as well as user friendly operation. An on-screen display facilitates display of information pertaining to the selected input and adjustment of picture settings, including positioning, size, zoom, brightness, contrast, color, tint, and detail. Internal test patterns are available for calibration and setup. Configurations can be conveniently saved and recalled from up to three memory presets per input. To enhance presentations, a special PIP - picture-in-picture mode allows video and RGB sources to be combined within the same image.

Features

Inputs: Composite video on BNC; composite video, S-video, and component video on BNCs; S-video on 4-pin mini DIN; universal input accepts all signal formats from composite video to HDTV component video and RGBHV on 15-pin HD; optional SDI Serial Digital Interface - supports SMPTE 259M-C 270 Mbps standard

Outputs: Scaled RGB or HD component video digital output on DVI-I, analog outputs on BNCs and DVI-I

RGB, HDTV, and video scaling — RGB computer video, high definition video, and standard definition video sources can all be scaled to the desired output resolution.

RGB upscaling and downscaling — The DVS 304 DVI features an advanced scaling engine with high quality upscaling and downscaling of high resolution computer-video signals.

Selectable output rates from 640x480 to 1920x1200, including HDTV 1080p/60 — Available output rates include computer video up to WUXGA, 480p, 576p, and HDTV rates at 720p, 1080i, and 1080p/60.

Simultaneous DVI and analog RGB or HD component video outputs — Digital and analog outputs on DVI-I, and analog output on BNCs are provided for driving up to three display devices.

EDID Minder^® automatically manages EDID communication between connected devices — EDID Minder ensures that all sources power up properly and reliably output content for display.

Auto Input Format Detection — Input four of the DVS 304 DVI can be set to detect the incoming signal format, automatically reconfiguring itself to provide the appropriate decoding and signal processing. This feature can reduce the number of required outputs for a matrix switcher, lowering system cost while improving manageability.

Auto-switching between inputs — The DVS 304 DVI can automatically switch between input sources. With auto-switching, the DVS 304 DVI can also accommodate additional inputs when connected to the outputs of a larger presentation switcher, such as the MPS 112.

Ethernet monitoring and control — Ethernet-enabled AV products, such as the DVS 304 DVI, can be managed and supported by a technician or administrator at any time from any authorized Web client. Ethernet control also enables the DVS 304 DVI to directly communicate with Extron Ethernet-enabled matrix switchers for faster, streamlined system operation.

Auto-Image™ setup — When activated, the unit automatically optimizes the image by analyzing and adjusting to the video input signal. This can save time and effort in setting up a newly connected source, particularly in presentation environments where different guest presenter laptops with various output resolutions will be connected.

On-screen display — The DVS 304 DVI features an on-screen display which displays status information pertaining to the currently selected input, and facilitates easy adjustment of picture settings.

On-screen input labels — An on-screen text label may be assigned to input four for each incoming signal. The label can be up to 16 characters and input via RS-232 or Ethernet. This feature is especially useful when identifying incoming signals from a matrix switcher.

Audio switching and output volume control — The DVS 304 DVI A and DVS 304 DVI AD feature audio switching for four stereo balanced or unbalanced input sources. In addition to master volume control and muting, gain or attenuation can be adjusted for each input to eliminate noticeable differences when switching between sources.
