The KONA LHi has a hardware-based downstream keyer that is ideal for putting logos, "bugs"
or other video material with an alpha channel on top of video being played out or printed to
tape. A typical application would be putting a television station's call letters or channel over
program video content. Keyed video can be from the KONA's internal Frame Buffer (from
storage, video In, KONA TV, etc.) or from a graphics file that has an alpha channel (PhotoShop
etc.).
