HISTORY

Faroudja Laboratories, located in northern Califor-
nia’s Silicon Valley, was founded in 1971 by Yves
and Isabell Faroudja to develop state-of-the-art
video processing technology. Over the last 26
years, Faroudja Laboratories has developed
hundreds of advanced electronic processes to
improve video enhancement, noise reduction and
NTSC encoding/ decoding technologies. Many of
these processes are used under license by 
the world’s leading electronics companies in a 
wide range of high performance video products.
Faroudja professional video equipment is also
currently hard at work in hundreds of television
studios. Thus Faroudja technology is utilized and
enjoyed in millions of American homes every day.

Yves Faroudja has devoted his career and his
company to the goal of enabling home video
systems to achieve the image quality of 35mm

2

motion pictures. Faroudja’s unique approach focus-
es on critical problem areas in the NTSC and PAL
broadcast format. With patented engineering and
design work, Yves and Faroudja Laboratories have
created an exceptional product that brings new
levels of visual reality to the enjoyment of discern-
ing video enthusiasts around the world.

This booklet will provide the reader with a hands-on
look at the VP250SE, its operation and benefits. 

Also supplied is an overview of the proprietary tech-
nologies utilized in this extraordinary device and an
explanation of the visual improvements it provides
in home video and corporate playback systems.

Some Video History and the Faroudja Approach

This manual is for use with the VP250SE which handles both NTSC and PAL sources. For sim-
plicity the documentation references NTSC. All instructions for installation and operation are the
same for PAL sources
