Overview
2 Harmony 2ES and 4ES
Technical Description
The Focus Enhancements Harmony 2ES
™
and Harmony 4ES
™
cards are PCI MPEG decoder cards that support respectively,
two or four independent outputs (channels) of high-quality
video playback. These Harmony cards have their own unique
driver and API structure designed to offer maximum
compatibility with Focus Enhancements ReelTime series cards.
The Harmony 4ES simultaneously outputs composite and
high-quality S-video, along with either Dolby Digital audio or
Stereo PCM audio via S/PDIF. Alternately, Harmony 4ES can
also output RGB (sync on green) or component video.
Maximum Number of Cards in a Server
The maximum number of Harmony cards supported by a
server depends on the method used to configure their
operation.
Vidserve
Standard implementation using the Harmony Vidserve
program permits a maximum number of 6 Harmony cards
with a possible total of 24 channels.
Serial Command Interface
Using the Serial Commands interface and information
provided in the Harmony SDK, the server may contain 8
Harmony cards with a possible total of 32 channels
On Screen Display
The Harmony 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 six 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.
