INTRODUCTION
General Description
Congratulations on your purchase of the DTV-947/VHD Controller system! The processor is designed to work with the DTV-947 projector, and will provide full aspect ratio control as well as greatly enhanced picture quality. As a result the aspect ratio control feature within the controller allows the projector to stay in a single memory, making integration into the system much easier.
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 inter- laced 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 graph- ics 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.
