First Video Capture IC to Connect Directly to VGA Controller.LAS VEGAS--(BUSINESS WIRE)--Nov. 19, 1996--Philips Semiconductors today announced the industry's first single-chip video capture front-end to connect directly to a 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 controller. The SAA (Systems Application Architecture) A set of interfaces designed to cross all IBM platforms from PC to mainframe. Introduced by IBM in 1987, SAA includes the Common User Access (CUA), the Common Programming Interface for Communications (CPI-C) and Common Communications 7112 is the first in a new generation of ICs from Philips for image port/memory attached architectures designed to enable a new range of multimedia-enabled VGA cards and motherboard solutions. With its multistandard decoding of 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. , PAL and SECAM (SEquential Couleur Avec Memoire, Sequential Color with Memory) A color TV standard from France that was officially introduced in 1967. Although development began in 1956, it took time to convert from the earlier French 819-line system. , high-performance 3-D scaling, versatile image port interface, and digital video expansion port, the SAA7112 offers a high-level of integration in a single piece of silicon, eliminating the need for glue logic in the design of highly featured VGA/video solutions. As a result, designers save time and money, and significantly reduce the time-to-market in the production of new VGA-based multimedia products. "It is the most advanced video front-end solution on the market today," said Burkhardt Frick, international product marketing manager with Philips Semiconductors' Multimedia PC group in Europe. "Providing glueless capture of video data at the image port of VGA/VGC controllers is ideal for video conferencing, image and text processing solutions on the desktop, as well as for digital video add-in card and motherboard applications." The video image port interfaces directly to the majority of VGA controllers and is configurable to support a variety of set-ups. In addition, a bi-directional video expansion port with half-duplex functionality allows either real-time decoded YUV The color encoding system used for analog television worldwide (NTSC, PAL and SECAM). The YUV color space (color model) differs from RGB, which is what the camera captures and what humans view. data to be output from the decoder, or a second video stream to be input directly to the scaler (for example from an MPEG decoder or video phone CODEC). The SAA7112 decodes NTSC, PAL and SECAM signals and their respective sub-standards to CCIR-601 color component values, using Philips line-locked clock decoding. This ensures excellent picture quality for all standards, along with stable, high quality decoding of even weak and distorted signals, such as from VCRs. It also incorporates two analog pre-processing channels with built-in source selection, anti-aliasing filters, 8-bit A/D conversion, automatic gain and clamp control and line-locked clock generation. Through these two channels it can accept a combination of six 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 or S-Video (Y-C) inputs. A programmable VBI See vertical blanking interval. bypass mode further allows the processing of multistandard text and Intercast data. The high-performance 3-D scaler core is an enhanced version of the core in Philips' stand-alone scalers, providing horizontal and vertical up (2x) and down (1/64x) scaling to arbitrarily sized windows, with up to 64 tap filtering. Capable of processing up to 2047 active samples/line and lines/frame, it has two independent programming sets permitting the definition of two 'ranges' per field as well as frame and field rate reductions. On-board field-wise switching between decoder and expansion port inputs is provided, for applications such as video conferencing where a main picture and a vanity picture can be used. Scaling using 3-D phase correct interpolation interpolation In mathematics, estimation of a value between two known data points. A simple example is calculating the mean (see mean, median, and mode) of two population counts made 10 years apart to estimate the population in the fifth year. provides horizontal zooming and re-sampling to improve signal quality, required for compression (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). ) and video phone applications. Limited samples of the SAA7112 are available now, with engineering samples due in March, 1997.
