1. Introduction
1.1Introduction to MV4
MV4 is a powerful, universal and user-friendly image analyzing processor with 4 DVI
input ports and 4 output ports. It is not only a matrix switcher, but also a Multi-viewer or
video wall processor.
As a video wall processor, MV4 is able to zoom in one input image three/ four times to
the outputs. And as a Multi-viewer processor, MV4 can mix inputs with any combos to
one image, and then transfer to all the outputs. It also supports output resolution
change, contrast & brightness adjusting, H&V zooming and moving, and bezel
adjustment.
MV4 provides with various ways for system control through its control ports, such as
the RS232 serial port, USB interface, and the TCP/IP network port. It can be controlled
easily by using the control software MV4Demo.
It has a good application in various occasions, such as TV broadcasting, multi-media
meeting room, network operations center, medical institutions, command & control
center etc.
