INTRODUCTION

General Description

Congratulations on your purchase of the VHD-4403 ULTRA! This processor is designed to work with either a CRT projector or a fixed-pixel device (DLP, Plasma, etc.), and will provide full aspect ratio con- trol as well as greatly enhanced picture quality. For example, DLP projectors were not initially designed to be used on wide aspect-ratio screens (16:9 or 1.85:1). The VHD-4403 ULTRA, however, expands the use of the DLP projector to be able to accommodate Letterbox, anamorphic (16:9) and 4:3 images on your wide-aspect ratio screen. This allows you to use the full benefit of your widescreen without having to sacrifice aspect ratio control. When using the VHD-4403 ULTRA with a CRT projector (i.e. DTV-940), the aspect ratio control feature allows the projector to stay in a single memory, making inte- gration into the system much easier.

The VHD-4403 ULTRA is not only an aspect-ratio controller, but is also scaler with a progressive out- put, which virtually eliminates motion artifacts as a result of interlaced signals. Also, its 10-bit process- ing results in the cleanest, most resolved video images a processor can provide.

This preliminary version of the VHD-4403 you have just received has all of the features noted above, and has a scan rate output (45 kHz) optimized for the Runco projector you have purchased.

This processor will be upgradeable in the future; these upgrades include multiple scan rate outputs and the ability to optimize the output for either CRT projectors or fixed pixel devices. This upgrade will either be in the form of an exchange with a fully upgraded unit, or a software upgrade which involves a simple chip replacement. Please contact Runco for more updated information regarding these upgrades.

Features and Benefits

The VHD-4403 ULTRA has many great features and benefits that make it a flexible, high-quality processor. Its many benefits include:

•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 composite and S-video.

•Inverse Telecine (3:2 pulldown) detection and processing allows the scaler to almost completely elimi- nate 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 projector.

•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.

•A Dual-Screen actuator output for both Widescreens and 4:3 screens is provided

•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 or the front panel.
