1.1 General
The TVB-400 is a multiple format switching video scaler. It has 4
different types of video inputs and a scaled output that can be switched
to any of the inputs.
Inputs are: Composite Video (NTSC or PAL), S-video (NTSC or
PAL), Component Video (SD and HD from 480p to 1080i), and a PC
(from VGA (640x480) to SXGA (1280x1024) for scaled output, or up
to 1920x1440 for pass thru video).
The output format and resolution can be specified by the user as either
PC (VGA (640x480) to SXGA (1280x1024)) or Component Video
(YPbPr from 480p to 1080i - a VGA to 3 RCA adapter cable is
included). The user can set the output to the optimal sweet-spot of
your display and let the TVB-400 handle and convert various kinds of
video inputs for your LCD.
The TVB-400A is the same as the TVB-400 but adds audio switching
and volume control capabilities (for line level audio).
The Video Scaler can be controlled in many ways including: front
panel lighted pushbuttons (with On-Screen Display menus), using the
included IR remote control, or RS-232 Serial interface. The controls
include: input switching, setting the output resolution, picture
adjustment (tint, color, brightness, contrast, and sharpness), aspect ratio
(Standard, 16:9 or 4:3), digital noise reduction, 3D comb filter On/Off,
volume control and many other advanced features.
The TVB-400 is ideal for use with in boardrooms, classrooms, digital
signage, and high end home-theater applications. Its output can be set
for any LCD projector, PC LCD monitor, plasma, or HDTV displays.
