Chrontel Offers a High-Performance Video and Graphics Multiplexer With Programmable Analog Color Key.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--Oct. 21, 1996--Chrontel, Inc., a leading supplier of innovative video and graphics integrated circuits, today announced a high-performance and feature-rich integrated circuit that allows video and graphics to appear on the same display. The CH8439 video and graphics multiplexer supports displays with up to 1280x1024 pixel resolution pixel resolution Telemedicine The sharpness of a computerized image, based on pixel concentration, which determines display resolution and 16.7 million colors. The unique features of the CH8439 are its ability to accept full bandwidth 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). graphics and control the mixing of digital video inputs using a programmable analog color key and high-performance genlock. Previous video vendors used digital RGB graphics coming from the VGA feature connector A point-to-point channel used to transfer video signals between two video controllers, typically between the display adapter and a video capture or TV board. Using an 8-bit data path, it provides 40 Mbytes/sec bandwidth. , which limited the bandwidth to 800x600 resolution. Furthermore, many new systems no longer support the infrequently-used VGA feature connector. By enabling the input of direct RGB analog signals, the CH8439 can support resolutions up to 1280x1024 with full 24-bit color on any system. "The biggest challenge for Chrontel was to maintain high performance color key support while using the analog RGB inputs," stated Ken Lowe, Chrontel's director of marketing. "Other vendors' attempts to provide this feature resulted in 'bleedthrough' of the RGB graphics into the color-key window intended for video images. Chrontel's proprietary leakage suppression technology enables the CH8439 to support full color-key control while limiting graphics bleedthrough to less than one pixel." The CH8439 features dual analog wide-band drivers, YUV-to-RGB color space conversion Changing one type of color-encoded signal into another. Converting from RGB to YUV and back to RGB are common color space conversions when working with video formats (see YUV). Converting from the display color space (RGB) to the printer color space (CMYK) is another common example. , and a serial programming interface for video attribute control. Markets and Applications Applications for the CH8439 include MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). add-in cards, video tuner cards or any application that requires the combination of graphics and video in the same screen. In addition to consumer products, industrial and military applications such as instrumentation and simulation are potential markets for the CH8439. Pricing and Availability The CH8439 series is available immediately in 64-pin PQFP (Plastic Quad Flat Package) Refers to many varieties of QFP chip packages, which are molded in plastic. See QFP. , and is priced at $9.75 in quantities of 1,000. Chrontel, Inc. designs and develops innovative mixed-signal integrated circuits for the consumer electronics and computer markets worldwide.
