Split Key
Sometimes you may wish to use the key cut signal of one source with the
key fill or video signal of another source. For example, you may have a
Character Generator creating matte filled characters, but wish to use a dif-
ferent signal to fill the characters. A split key is used to accomplish this.
On the Karrera system, the source select buses by default tally the key fill
signal.
