DK320 Series
Multiple HD/SD Digital
Downstream Keyer
DK320
is 1-U rack-mountable chassis which is built-in three separate
digital downstream keyers. With comprehensive A/B vision
mixer, like fade in, fade out, cross dissolve, etc., it can be
used in conjunction with the keyers to produce a composite
transition.
DK320
provides 2-channel digital background signals input, and
switched out to any one channel seamlessly with the internal
2-channel 10-bit digital frame synchronizer. Supports
the embedded SDI signal as the Fill input signal. DK320 also
could be used as the de-embedded unit to output 1-channel
analog composite video and 1-channel un-balanced stereo audio
for the preview feature.
DK320's each
digital downstream keyer could be independently controlled. It provides the setting function on each different digital
keyer, and it could be easily switched over the background or
other keyers by the digital keyers' sequence.
DK320 provides the ability
to preview the signal with key-in and allowing the users to
set all of the parameters prior to the transitions before the
program output.
Dk320 provides the
users do the custom the transition rates of the fade-to-black
feature. DK320 could detect each of the input keys and
switched to the back ground automatically when there is no any
input digital key signals.
