AITech International is the industry leader in the development and delivery of PC-to-TV scan conversion technology. The company was founded in 1987 by Dr. Michael J.W. Chen, the Founder and Chairman, and is located in the Silicon Valley of California, U.S.A. It develops and markets integrated circuits, external system peripherals, and internal board-level products, which has been patented with VSPro™, FlicFree™ and other technologies. Currently, the company starts to market broadband information appliances and Internet Set-top Boxes. It has established long-term co-operations with more than one hundred companies in North America, Europe and Asia Pacific regions in both business and technology.

AITech's patented VSPro™ technology converts the computer's VGA signal to NTSC, PAL, and TV standards. AITech's high performance chips, cables, boards and peripherals, including the best selling Web Cable Plus, Pocket Scan Converter, MultiPro™ series PC-to-TV scan converters, AIGotcha!TM2 video capture device and the AIT1108, AIT1168, AIT2138 single-chip scan conversion integrated circuits, are marketed worldwidely.

AITech (Shanghai) Co., Ltd. is a solely owned enterprise invested in Shanghai by AITech International Corporation. Founded in 1996, the company has been involved in the manufacturing, sales and marketing, research and development, and technical services of the video signal conversion product line of AITech International.From 2000, AITech Shanghai began its local manufacturing try for part of popular scan converters of AITech product line. The low-cost, upgrade and custom design for local market, as well as the effective supply chain benefit China end users soon. Export and international business are also set up.AITech (Shanghai) Co., Ltd. is formed by a group of qualified, experienced and innovative employees on management, marketing & sales, and R&D engineering, who are working closely and efficiently to develop and serve the dramatically growing market in China and Asia Pacific.

Technology & Applications AITech's video scan conversion technology transforms the video output (non-interlaced VGA RGB) of a PC to a television-compatible format (interlaced NTSC and PAL), enabling users to display PC-based images such as animation, slide shows, financial presentations, and Web sites on large screen televisions.

Targeting the Internet and Information Appliances (IA) markets, AITech will continue to be a technology leader by providing next-generation products and solutions to consumers of Internet TV, set-top boxes and portable IA.

Patented Technologies 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 AIT1108, AIT1168 and AIT2138. 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 FlicFree™ filter provides selectable filter settings to produce a clear and stable TV image. In addition, AITech's single-piece Web-Cable design (Computer to TV connection) has obtained patent grants in both U.S. and in Taiwan. AITech has a total of seven patents filed or approved in U.S. and other leading nations.
