AITech Announces AIT1168 Single-Chip Video Signal Processor for VGA-to-TV Video Scan Conversion.FREMONT, Calif.--(BUSINESS WIRE)--Oct. 13, 1997-- Latest IC Generates TV-Size Underscan Display - For PCs, NCs, Internet Appliances, and Add-In Cards AITech International, the world leader in scan conversion For conversion of vector images to raster images, see . Scan conversion or scan rate converting is a technique for changing the vertical / horizontal scan frequency of video signal for different purposes and applications. and desktop video technology, today announced the AIT1168 Video Signal Processor (VSPro). The single-chip AIT1168 generates clear, stable analog CVBS CVBS Composite Video Baseband Signal CVBS Composite Video Broadcast Signal CVBS Composite Video Blanking Sync CVBS Color, Vision, Blanking, Synchronisation CVBS Composite Video Blanking and Synchronization and S-VHS (Super-VHS) A VHS recording and playback system that increased resolution from 240 to 400 lines and used a higher-quality cassette. S-VHS introduced the S-video interface, which separated the luma from the color (see S-video). NTSC (National TV Standards Committee) The committee that developed the television standards for the U.S, which are also used in Canada, Japan, South Korea and several Central and South American countries. Both the committee and the standard are called "NTSC. and PAL TV video from the non-interlaced, analog RGB (Red Green Blue) The computer's native color space, which is the color system for capturing and displaying images. RGB was derived from our own perception of color because human eyes are sensitive to red, green and blue (see trichromaticity). signals of VGA (Video Graphics Array) The display standard for the PC. All PC display adapters support VGA, and Windows machines boot up in "VGA mode" before switching to higher resolutions. graphics controllers. Fully upgradeable from its predecessor, the AIT1108E, the AIT1168 integrates hardware scaling to provide TV-size underscan display of 640 x 480 and 800 x 600 computer graphics and video images. Samples of the AIT1168 will be available in October, direct from AITech or its authorized distributors, at $20 each. The AIT1168 addresses a wide range of applications. It can be integrated into PCs, Network Computers (NCs), Network PCs (NPCs), Internet Appliances, and Set-Top Boxes. It can provide advanced VGA-to-video conversion for add-in cards, 3D graphics accelerators, and game applications. Its VESA DPMS power down modes make the AIT1168 an excellent choice for TV-out for embedded desktop and portable PCs. "There are two key requirements to displaying VGA signals on the TV: the first is meeting the video standards, and the second is providing good scaling, filtering, and image signal processing to make the TV image accurate and pleasing for viewing," said Richard Lee, AITech's executive vice president and general manager of the company's Microelectronics division. "The original 1108 chip surpassed those requirements and established AITech's leadership position in providing the best looking TV image. The new AIT1168 raises the bar for image quality." The AIT1168 uses triple 8-bit A/D converters to digitize analog RGB input signals. All video signal processing is done in the digital domain with no need for tuning circuits. The encoded video signal is converted to analog CVBS and S-VHS TV signals by triple high resolution 10-bit DACs, providing improved text clarity and very high quality video output. The AIT1168 requires no additional microcontroller, and maintains precision timing via a single 27 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. crystal. Hardware development kits for the AIT1168 include the chip, evaluation board, schematics, Gerber files, bill of material, and application notes.
