INTRODUCTION

General Description

Congratulations on your purchase of the VHD Ultra Controller video processor with Vivix™ technology! This processor is designed to maximize the image quality of your fixed-pixel display or rear-screen television while adding an extra level of flexibility to your system. The VHD Ultra Controller's Vivix™ processing techniques enable this processor to be used most efficiently with fixed-pixel displays, and will provide the most stunning image that your display can possibly deliver.

Vivix™ is a proprietary technique developed by Runco engineers to match the output resolution of the proces- sor precisely to the display it will be used with. This precision processing technique resolves all the problems that conventional video processors have with fixed-pixel displays, which include pixel-tracking artifacts (jagged lines, moiré, jerky motion, etc.), too much overscan (significant loss of image) and even improper and disproportionate aspect ratios. The results of Vivix™ technology is an image that nearly rivals that of a CRT, while providing three geometrically-correct aspect ratios on a 16:9 or a 4:3 screen.

Features and Benefits

The VHD Ultra Controller have many great features and benefits that make it a flexible, high-quality processor. Its many benefits include:

•VivixTM Technology, which maximizes image quality and flexibility of fixed-pixel displays.

•An adaptive 2-dimensional comb filter that greatly reduces artifacts when using a composite video signal as an input.

•A Luma edge enhancement circuit makes the edges of objects appear sharper without the ringing and noise increase associated with traditional sharpness circuits

•A Chroma edge enhancement circuit is included to compensate for lower chroma resolution found in com- posite and S-video.

•Inverse Telecine (3:2 pulldown) detection and processing allows the scaler to almost completely eliminate interlace artifacts associated with other scalers

•The controller can correctly scale anamorphic, letterbox and 4:3 formats to fit on a wide aspect-ratio screen, and scale anamorphic formats on a 4:3 screen

•A pass-through connector is supplied for routing HDTV or computer graphics directly to the display.

•An RS-232 input is provided for easy integration into the automated home theater environment

•A TBC (Time Base Corrector) circuit is provided for unstable sources such as VCR’s.

•12V outputs are provided for drop screens and screen masking.

•A simple 7-button remote controls all aspects of operation. One button source selection and aspect ratio control is also provided via the remote control.
