Founded in 1987, AITech International Corporation
is the industry leader in the development and delivery of
PC to TV scan conversion technology. The company develops
and markets PC to TV video scan conversion technology in integrated
circuits, external system peripherals, and internal board-level
products, for use in portable or desktop video, multimedia,
imaging and other applications. Its patented VSPro^(TM) technology
converts the computer's VGA signal to NTSC and PAL TV standards.
AITech's high performance chips, boards and peripherals, including
the best selling Pocket Scan Converter, AIGotcha!^(TM)2 video
capture device and the AIT1168 single chip scan conversion
integrated circuit, are marketed worldwide. AITech's latest
engineering accomplishment, the AIT2138, raises the performance
standard as a feature rich, high resolution PC/TV single chip
solution sure to dominate the global OEM TV display markets.
Scan conversion transforms the video
output of PCs video output (non-interlaced VGA RGB) to a television-compatible
format (interlaced NTSC or PAL). This enables PC video output
to be viewed on a television set, which is typically the larger
screen. The television video broadcast signal used in the
U.S. is known as NTSC, for National Television Standards Committee.
Countries in Europe, Asia, and other parts of the world use
the PAL (Phase Alternating Line) broadcast standard. Scan
Conversion technology enables users to display PC-based images
such as animation, slide shows, financial presentations, and
Web sites on large screen televisions (direct view and rear-projection).
These applications may take place in boardrooms, classrooms,
conference rooms and function halls where larger audiences
gather. Family and home entertainment applications are very
popular as well. With minimal effort and low cost, scan conversion
enhances the enjoyment of video game play, 'surfing the Net',
and computer DVD movies by enabling them to be viewed on any
VSPro™ is AITech's patented video
signal processing technology, which is used in the company's
scan conversion products. It is becoming the dominant technology
in its industry, and is considered by many to be the de facto
standard for scan conversion.
VSPro is a high-speed, digital signal processing technology.
It is implemented in AITech's single chip scan converter products,
such as the AIT2138 and AIT1168. The IC architecture, feature
sets, and programmable options provide complete single-chip
system solutions for all PC-to-TV applications. AITech pioneered
the single-chip integration of analog-to-digital (ADC) conversion,
color space conversion, digital filtering, precise PLL timing,
video encoding, and digital-to-analog (DAC) output of the
NTSC/PAL signals. These and other innovations make VSPro the
most advanced, yet cost-effective scan conversion technology
available. Due to the differences between VGA and TV signals,
converted images are often unstable and "flicker".
AITech has developed the proprietary FlicFree™ filter,
a significant part of VSPro technology. The Flic-Free™
filter provides selectable filter settings to produce a clear
and stable TV image.
