DES-3901-S and DNS-3901-S Installation and Operation Manual

Chapter 1: Introduction

Main Features

These are the main features of the DES-3901-S and DNS-3901-S
composite video decoders:
•

12-bit input processing with NTSC/PAL-B/PAL-M support

•

Auto-detect or user-force input standard

•

User-selectable input locks for horizontal-lock, chroma lock or auto
options

•

Automatic subcarrier-to-horizontal SCH error correction

•

Fully adaptive comb filtering in frame, field, 3-line adaptive, and
notch modes (with user-selectable enable/disable for each filter)

•

Line-by-line selection of vertical blanking interval (VBI) filter in
normal, simple, bypass, and delete modes

•

User-adjustable setup removal for starting line, chroma phase, and
tint controls

•

User-adjustable luminance, chrominance, and setup levels

•

On/off Hanover Bar suppressor for PAL signals

•

Digital equalization

•

Built-in color bar generator

•

Four SDI outputs

•

Cable equalizer

•

Noise reduction capability (DNS-3901-S)

•

Two jumper-based, user-selectable composite monitoring outputs
(alternating with SDI outputs)

•

SDI input with color decoder bypass for “future-proofing”

•

Large-input noise immunity

•

Soft black and white input video clipping

•

Picture position adjustments

•

On-board diagnostics

•

Capability for card-edge control, or hardware control panels and
GUI applications (3901RES-E resource module is required for
Ethernet and control panel use)

•

SDI processing amplification with adjustments for black level,
luminance gain, chrominance gain, and hue; black and white level
clipping
