AK300
Multiple Analog
Downstream Keyer
AK300
is a 1-U rack-mountable chassis which is built-in three separate
analog linear keyers which is compatible with both NTSC or PAL
video standard. With the ability of cuts, mixes and wipe
transitions, any CGs or Logos with ALPHA channel could be
combined into the main back ground to produce a composite
transition.
AK300 provides one channel
analog back ground input plus two stand alone preview and
program signals output.
With
12-Bit internal processing, AK300
avoids the dentation and flicker problems.
AK300 could detect each of the input
key signals, and will be switched to the back ground automatically when there is no any
input key signals. In case of no back ground input, AK300
could output the black frame to maintain the valid output.
