Extron’s VSC 75 high resolution computer-to-video scan converter uses
Extron’s exclusive advanced digital processing to convert highresolution computer-video images from as high as 1280 x 1024 @ 60 Hz
down to NTSC or PAL video for use in videoconferencing, video
recording, or viewing applications. Videoconferencing users at the near
end may integrate computer sources into their conferences by scan
converting higher-resolution signals down to composite video or
S-video for CODEC input. The VSC 75 utilizes 720 pixels per line
sampling to capture high-resolution information, ensuring sharp image
output. An internal test pattern generator outputs color bar patterns
for setting up color adjustments.

connection to any Macintosh or IBM-compatible computer. The
passive local monitor output allows the user to display images on
the local monitor as video plays simultaneously on the display
device.
■ Outputs – Outputs NTSC or PAL video as composite video and
S-video outputs.
■ Memory locations– Includes 30 factory/user memory presets for
horizontal & vertical sizing, vertical filter, and horizontal &
vertical centering settings with autosave and auto-recall.
■ Internal test pattern generator – Outputs color bar patterns for
setting up color adjustments.
■ Picture controls – Freeze, horizontal & vertical sizing, zoom, and
horizontal & vertical centering/pan controls available.
■ Vertical filtering – Two user-selectable levels of vertical filtering
reduce flicker.
