1Introduction

The Focus Enhancements TView QuadScan product family is a series of products intended to receive analog television signals in various formats, scale them upwards in resolution and play them back on high-resolution projection devices. Using the QuadScan, users can vastly improve the visual quality of television sources.

The QuadScan is a Video Scaler, which means that the output resolution can be controlled or “scaled” to fit the resolution of the output device. “Line Doubling” and “Line Quadrupling” are just 2 of the many scaling modes of the QuadScan’s operation.

In addition to scaling incoming video to the optimum resolution of the display device, the QuadScan provides 2 other functions in significantly improving the displayed quality of television: 1) the video is de-interlaced for presentation on a non-interlaced device, removing the effects of interlaced flicker and 2) the video is “motion compensated”, automatically detecting the input source (i. e. still video, motion video, or film) and processing the video for minimal motion artifacts.

The QuadScan III is intended for use in two major type of users: Professional AV Users, and Home Theater Users Professional AV users will be able to control all of the QuadScan’s control functions from popular control environments via RS-232/422. Home Theater Users will be able to access powerful video enhancement features previously found only in devices costing $10,000 and up.
