The 8995DNC is a compact, broadcast-quality
fiber-ready downconverter. Conversion is of
the highest quality, with pixel-adaptive motion
processing. In addition, the 8995DNC provides
the most robust signal handling with the low
hysteresis synchronizer, redundant reference,
and perfect-picture mode of the 8985FS.
It is fully featured with color-space conversion
and a powerful video proc. amp, including RGB
color correction with gamma and component
adjustments with Y/C clip level adjustments.
Powerful embedded audio handling includes
channel-level and Dolby E stream routing. PCM
audio processing eliminates the clicks caused
by the video synchronizer dropping or repeating
frames. This module silences the effects of hot
upstream video switching using a V-fade.
VITC and closed caption conversion
are supported for same frame-rate
downconversions, making this an ideal
module for playout applications.
One of three types of optional SFP fiber optic
submodules can be installed in the fiber optic
rear cage connector to provide two fiber
inputs (Dual Receiver), two fiber outputs (Dual
Transmitter), or one fiber input and one fiber
output (Transceiver).
Refer to the module pinout and block diagram
on the next page.
This module can be mounted in a GeckoFlex
frame but not in other 8900 series frames,
including Gecko-A or Gecko-V frames. As this
module has no card-edge controls and in order
to configure this module an 8900NET (Net Card)
Network Interface module is required.
