Introduction
The Visual Circuits Harmony 4E card is a PCI MPEG decoder card
supporting four independent outputs or “channels” of high-quality
video playback. The Harmony 4E has its own unique driver and
API structure designed to offer maximum compatibility with
Visual Circuits ReelTime series cards.

Harmony 4E simultaneously outputs composite and high-quality S-
video, along with either Dolby Digital audio or Stereo PCM audio
via S/PDIF. Alternately, Harmony 4E can also output RGB (sync
on green) or component video.
The Harmony 4E card also supports a dynamic On Screen Display
(OSD) of 256 colors with varying degrees of transparency. Since
all video decoding is performed through hardware, not only can a
single four-channel card run in four independent outputs, but two
cards are supported in the same server as well. The Windows 2000/
NT driver also includes a Software Developers Kit (SDK) with
libraries and a sample program allowing flexibility and
customization.
