VGA is the standard video display format for
computers. If one is trying to display VGA display
content on a cable television system there are some
impediments, since the two systems use different
Our Apollo II is designed to bridge the gap between
these two worlds.
It consists of three elements: 1) Analog to digital
video converter; 2) MPEG-2 encoder; and 3) QAM/
DVB-C modulator.
The Apollo II™ Scaler Modulator is among the first
modulators specifically designed for digital signage
integration. The onboard in-stream scaler ingests
video at PC resolution, converting the output to
1080i or 720p video. In addition the scaler features
up and down-scaling, zoom, shrink, and positioning.
To use this, one merely connects to the “cable”
input of a digital television.
The target application for this product is “digital
signage” since QAM/DVB-C is a very inexpensive
“one to many” content delivery technology. VGA is
a very inexpensive way to create quality and
relevant information.
