The Faroudja VP400A Video Processor is a precision video instrument used to convert NTSC Composite, Y/C, or 525 line RGB or Component interlaced signals into 1050 line progressive outputs.
Using the VP400A Video Processor will produce
pictures with more details, remove unwanted picture
artifacts and, when used with projection systems,
produce pictures of exceptional quality, giving a
“cinema-like” feeling.
Front panel features include Power, Input Select
(Video, Y/C, RGB and Component), Brightness,
Contrast, Color, Auto-Tint, Noise Reduction, Detail,
Digital Filter and Freeze. Input switch settings are
memorized when the power is removed from the
unit. This allows the VP400A to be interfaced into a
system without the need to select the input when
the system is powered up. The remaining controls
may be left in factory preset or manually set by
pulling out and rotating the control until the desired
level is established.
Inputs to the VP400A include: Composite Video,
Y/C (S-VHS), RGB and Component (Y,R-Y,B-Y). The
Video input may be connected by either a BNC connection
or a video RCA type connection. These
inputs are looped internally so that the signal may
be used by other devices. A selectable 75 Ohm terminator
switch is provided and should be in the ON
position if the input loop is not used. The Y/C input
uses a standard 4 pin S-VHS connector. This input
is not available for a looped operation and is terminated
internally. The RGB and Component inputs
use BNC connectors. As with the video input, these
inputs are loopable to other devices. Selectable 75
Ohm terminations are provided. If the looped inputs
are used, these cables should be kept short, (under
6' in length) or a video distribution amplifier should
be used. This allows the VP400A to keep the highest
signal bandwidth possible without having the
high frequency being attenuated in a long cable.
Output from the VP400A is provided on six BNC
connectors as well as one 15 pin ‘D’ connector. The
BNC outputs provided are Red, Green, Blue,
Horizontal Sync, Vertical Sync and Composite Sync.
Interface to monitors/projectors can be of a 4 or 5
wire connection. Note: 4 wire, meaning Red, Green,
Blue and Composite Sync or 5 wire, meaning Red,
Green, Blue, Horizontal Sync and Vertical Sync.
There is no sync present on the Green output. The
VP400A is capable of driving a monitor/projector
using the BNC outputs as well as a 15 pin ‘D’ connector,
at the same time. The monitor and projector
have to scan at 62.94KHz Horizontal scan rate.
The VP400A features a RS-232 remote control
interface that will allow control of all line quadrupler
functions. The remote control uses a 25 pin female
‘D’ connector located on the rear panel.
