Extron electronic Multi-Graphic Processor MGP 464 Manual De Usuario

This manual discusses how to install, configure, and operate the Extron MGP 464 

multi-graphic processor.
Throughout this manual, the terms “MGP,” “multi-graphic processor,” and 

“processor” are used interchangeably to refer to the same product.  

The MGP 464 is a four-window RGB and video signal processor that can display up 

to four video sources on a single screen in picture-in-picture or picture-by-picture 

format.  The MGP accepts RGB, HDTV, component, S-video, and composite video 

signals on four fully-configurable inputs and 15 virtual inputs; and has one scaled 

output.  The processor provides switching among inputs and has picture controls 

and presets. 
The MGP 464 DI is an MGP 464 with a DVI input card installed, providing four DVI 

input connectors.  Both versions can be controlled remotely via the RS-232/RS-422 

interface using Special Instruction Set (SIS

™

) commands or the Windows-based 

control software, or via an Ethernet LAN using the MGP 464’s embedded Web 

pages, SIS commands, or the Windows-based control software.

— Up to four windows can be shown on a single display 

simultaneously, allowing up to four video and computer sources to be viewed 

at once.

— The MGP 464 has four fully configurable video inputs, which accept RGB, 

HDTV, component, S-video, and composite video signals.  The MGP 464 DI 

has four DVI inputs in addition.

 — A DVI input is provided on both models as a means to 

display live video from a DVI source as a background.

 — 15 virtual inputs can be configured through software to accept 

standard definition component video, S-video, and composite video.  

— The MGP 464 has one scaled output, available on a set of five BNC 

connectors for RGB and a DVI-I connector for DVI.

— Picture controls allow you to adjust the size, position, 

brightness, contrast, color, tint, detail, and zoom for each window.

— Window presets save sizing, positioning, and 

priority information.  Input presets save input signal type information and 

picture control settings.

— Six types of window transition effects (22 different 

effects altogether) seamlessly mute and unmute (close and open) the four 

windows.

— Freeze control freezes (locks) a window to the current image.

— 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.
