TV-to-VGA Converter

When enabled, OSD (On Screen Display) shows the selected TV input
for a few seconds, or if the selected input does not have video, it
continuously indicates the selected input. Screen Saver feature moves
the OSD around the screen when no video input is detected. The OSD
can be permanently disabled via the serial port.
The front panel can be locked out. This is a handy feature in many
installations. For example if the system is in “Auto” mode, the installer
may which to also lock the front panel so that accidental hitting of the
front panel switches does not take the system out of Auto mode.
The unit features a front panel switch for enhancing the TV video input
prior to display on a VGA monitor. The enhancement is based on non-
linear Gamma correction. If the TV video input has dim areas as well
as bright areas (such as in endoscopes used in medical procedures),
simply increasing the brightness would not be desirable since it washes
the entire image out and causes the already bright areas to “bloom”.
The enhancement feature of the TVB200-Plus brings out the details in
the dark areas without over driving the already bright regions of the
image.
The Serial input give the user or installer full control over all aspects of
the device including:
Contrast, Brightness, Saturation, Hue, OSD,
Front Panel Lock, Volume settings, Auto mode, TV format
(NTSC/PAL), Enhancement factor, and more
. Hall Research offers a
free download of PC compatible Windows™ control software that
allows you to select inputs and set all operating parameters of the unit.
The unit features non-volatile memory to store all of the settings
including the selected channel and performance characteristics.
The Model TVB200-Plus is housed in a compact shielded enclosure
and includes a small power adapter and 6 ft video and audio cables for
connection to the PC’s VGA and sound outputs.
