Distributed Video Processing

WindoWall employs a distributed video processing architecture that dedicates a separate WindoWall high resolution graphics processor to each projector, video cube, or flat-panel monitor in the videowall system. Each WindoWall Processor allows for the display of up to four windows, each of which can show video, HDTV, or high resolution computer-video content. It employs proven Extron video processing technologies to deliver a fully optimized, high quality video output. The WindoWall Processor is compatible with virtually any available display and outputs high resolution video at resolutions up to 1600x1200 and HDTV 1080p/60.

Because a discrete, real-time processor is dedicated to each display unit in the videowall, WindoWall is fully scalable, supporting a wide variety of display layouts from 1x2 to 3x2 and larger. An Extron CrossPoint Ultra or CrossPoint 450 Plus Series matrix switcher is required for distributing input sources to the WindoWall Processors.

Graphical User Interface

WindoWall Console application software is the user interface to the system. It brings all of the WindoWall Processors and the matrix switcher together via TCP/IP, and provides the tools and features to set up, create, and manage videowall presentations with up to four windows per display or video cube unit. The software includes intuitive Wizards that take the user step-by-step through the process of setting up a videowall and then configuring all input sources and the matrix switcher to be used in the system.

Once set-up is completed, customized window layouts can be created with the aid of a virtual canvas that lets you size and position windows anywhere as they would be shown on the videowall display. A static or live background display behind the windows adds a theme to the videowall presentation. Window layouts can be saved to 100 available memory presets for future recall.

• Graphic Still Store enables use of uploaded graphics as background images — A powerful feature that enables uploaded BMP bitmap graphics to be stored in memory for use as background images to create themed multimedia presentations. Each WindoWall Processor can store up to six high resolution images, offering an easy way to display frequently used images such as a company logo.
• Live video background from a dedicated DVI source — In addition to Graphic Still Store, live, full-motion, high resolution computer-video or HDTV from a DVI source can be used as a background to any presentation.
• Auto-Image™ setup — Each WindoWall Processor automatically optimizes the image to the scaled output rate, eliminating complex set-up procedures.
• Input freeze control — Any input to a picture-in-picture window can be frozen via the front panel, RS-232 or RS-422 control, or IP Link.
• Text overlay for window caption labeling — Each picture-in-picture window can be labeled with a text label of up to 16 characters, generated through RS-232 or RS-422 control or IP Link. Custom options are available for text positioning, text color, character size, translucent or color-selectable background, and text border.
• Picture controls for each window, including color, tint, brightness, contrast, and detail
• 100 memory presets for videowall layout configurations — A total of 100 customizable presets are available to quickly save and recall window configurations for the videowall system. These presets can easily be configured using the WindoWall Console application software.
• 3:2 NTSC and 2:2 PAL pulldown detection — Advanced film mode processing techniques help maximize image detail and sharpness for NTSC or PAL sources that originated from film.
• Quad standard video decoding — The WindoWall Processor uses a digital, four-line adaptive comb filter to decode NTSC 3.58, NTSC 4.43, PAL, and SECAM for integration into systems worldwide.
• Internal test patterns for calibration and set-up — The WindoWall Processor offers 15 test patterns, including a crop pattern, crosshatch, 16 bar grayscale, color bars, alternating pixels, ramp, white field, 4 x 4 crosshatch for use with video walls, three film aspect ratio patterns - 1.78, 1.85, and 2.35, crop patterns for setting up side-by-side windows, and two patterns for fully populating 4:3 and 16:9 screens with 4:3 images. It also features a blue-only mode for proper setup of video color and tint levels.
• IP Link® Ethernet monitoring and control — An IP integration technology developed by Extron. IP Link enables WindoWall System control and management of all WindoWall Processors over a LAN, WAN, or the Internet.
• RS-232 and RS-422 serial control port — Using serial commands, the WindoWall Processor can be controlled and configured via the Extron Windows®-based control program, or integrated into third-party control systems. Extron products use the SIS™ - Simple Instruction Set command protocol, a set of basic ASCII code commands that allow for quick and easy programming.

WindoWall Product Commissioning is a proactive, on-site service

offered by Extron to help you ensure that the WindoWall videowall

processor system that you design or install meets your specifications for

performance, and those of your customer, prior to the system going into

full operation.

Prerequisites

• All equipment must be on-site, installed, connected, and tested

• Extron-approved A/V system diagram and window preset layouts

• Product commissioning must be requested at least 3 weeks prior to the

desired date of the service

What’s Included

• Pre-installation design review services – Extron Engineers are

available to assist you throughout the design process. We will review

your final system design diagram, prior to WindoWall commissioning, to

verify that the system can adequately manage all of the signal sources.

• Window layout optimization – Using your wire schematic and

window preset layouts, we will create a project file that includes all

aspects of the system including videowall parameters, I/O routing, and

Virtual Canvas presets. Once on-site, the Extron Engineer will verify the

presets, configure source parameters, and deliver to you a completed

project file.

• One to two days on-site with an Extron Engineer

• System optimization – An Extron Engineer will optimize all

MGP 464W WindoWall processors, including signal timing, clock and

phase, and size and position adjustments; color, tint, contrast, and

brightness settings; and other general image parameters.

• Basic WindoWall Console application software training for the

system operator – After the signal path is optimized, the Extron

Engineer will provide training on the User Interface; system adjustments;

window parameter settings; and using the Virtual Canvas, including setup

and recalling window presets.
