Description
The V6271 is a Serial Digital Video Distribution Amplifier with converters to analague
composite and component signals, which forms part of the Vistek V1600 range of interface
products. It is a 3U high card, which is fitted into either a V1601, V1603 or V1606 rack, from
which it gets its power and remote control. The module can also be housed in the 1-Box or 2-
Box. A passive rear module, 16VR1B or 16VR3B, is required for all signal interconnections.
The unit is fully dual standard for both 625/50 and 525/60 D1 signals. It can automatically
detect the input standard and operate accordingly, and it is also forced into a standard when
there is no input.
The unit can produce the analogue composite and component signals in various formats.
The formats are: -
Composite
PAL, PAL N, PAL M, NTSC, NTSC-Japan
Component
YC
(standard levels, Beta levels or US MII levels), with or without set-up
Y, Pb, Pr
(standard levels, Beta levels or US MII levels), with or without set-up
GBR
with or without set-up
An internal test pattern generator is also included for alignment purposes, producing either
Colour Bars or Pluge.
In common with all Vistek V1600 modular units there is local control, which lets the user
adjust all of the controls. In addition the module may be controlled remotely using the DART
system. DART is the general purpose control architecture supplied by Vistek and other
manufacturers, and enables full control and monitoring of this and all other V1600 units.
The front panel shows the status of the modules outputs and also has the Test Pattern on/off
switch, which operates when in local mode. All other local controls are located on switches
behind the front panel on the module. Local / Remote mode is also selected from a switch on
the front panel.
