MD800 Series
HD/SD Digital Video
Processors
MD800 has a few modules for
both HD-SDI high definition and SD-SDI standard definition
video format with the different feature modules compatible
with NTSC or PAL video standard including the HD/SD frame synchronizer, HD/SD ALPHA keyer,
HD/SD scan convertor from DVI/HDMI or WUXGA to the digital
video, and other digital video processing functions.
MD800 - FS The module of HD/SD-SDI frame synchronizer has two models for different
users’ requirements — SDI x1 or SDI x2. With SDI x1, the
unit is acting as a regular one channel HD/SD-SDI frame
synchronizer. With SDI x2, it could be used as two independent
channels frame Sync. or a one channel HD dual-link (SMPTE
372M) frame Sync. A broadcasting quality down scaler with
continuous anti-aliasing filter is built-in so either model
could be configured as down converter.
MD800-DVI
The module of
HD/SD scan convertor allows MD800 to accept digital
inputs from DVI or HDMI, as well as analog inputs from WUXGA
or RGBHV, then convert them to HD/SD-SDI video signal.
A broadcasting quality down scaler with continuous
anti-aliasing filter is built-in allow user to down-scale the
original PC or other graphics to a smaller area for either
picture-in-picture effect or for fitting the target SDI
resolution. The target video signal could also be chopped or
move horizontally and vertically. Together with the ALPHA key
module mentioned later, users are able to overlay such PC or
other graphics over the back ground SDI signal without using
any external video mixer.

MD800-K
The module of HD/SD digital down stream keyer gives MD800
the internal HD ALPHA key feature. High definition Alpha key
& fill SDI signals are feed into 2 SDI inputs then
overlay to either HD/SD-SDI or DVI/HDMI input backgrounds.
