INTRODUCTION

General Description

Congratulations on your purchase of the VHD Controller! This processor is designed to work with
the VX-3c Projector and will provide full aspect ratio control 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 Controller, 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.
The VHD Controller is not only an aspect-ratio controller, but is also scaler with a progressive
output, which virtually eliminates motion artifacts as a result of interlaced signals. Also, its 10-bit
processing results in the cleanest, most resolved video images a processor can provide.

Features and Benefits

The VHD Controller 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
•
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
•
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 remote controls all aspects of operation. One button source selection and aspect ratio
•
control is also provided via the remote control.
Automatic TV standard switching between PAL and NTSC.
