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.
