Model TVB200-Plus
1. Introduction
1.1 General
The Model TVB200-Plus converts an NTSC or PAL video signal to
VGA for display on PC monitors, projectors, or HDTV (in 480p or
600p modes). The converter de-interlaces and doubles the frame rate
by turning the interlaced TV signal into a "progressive scan" signal
suitable for high resolution display devices.
The TVB200-Plus provides multiple TV video inputs: two (2) RCA
composite video and one (1) S-Video - all with their own
corresponding stereo audio inputs.
Additionally, the TVB200-Plus provides a separate VGA and audio
input from a PC that can be switched to the output. This makes the
TVB200-Plus a 4 multi-standard input to 1 VGA output device.
The user can select any of the inputs using individual push-button
switches on the front panel. An RS232 serial port is available for
external control and/or changing the internal configuration of the unit.
The unit can also switch between the PC and TV inputs automatically.
When the device is in “Auto” mode, if no TV video signal is present, it
selects the PC input and as soon as a TV input is detected, it switches
to the TV input by itself. This feature makes the unit perfect for
educational facilities where the presenter does not even have to worry
about making selections on the TVB200-Plus.
The TVB200-Plus also provides 4 Stereo audio inputs, one for each
corresponding video input. The audio switching follows the selected
video input channel. In addition, each audio input has its own
adjustable volume setting making it perfect for balancing the output
volume level regardless of the input selection.
The TVB200-Plus's VGA output can drive VGA extension cables to
200 feet. It is recommended that when video extension cables are used,
only high quality multi-coaxial VGA or RGBHV (such as Hall
Research Standard or Ultra-Thin VGA cables) be used.
