7420-7
Fill/Key Mode
When the module is configured for Fill/Key mode separate Fill and Key signals are
provided to feed a Master Control switcher as an input source, in a similar manner as a
character generator. The 7420 can be genlocked to an external reference to match the
timing of the Master Control device as shown below.
Dual Channel Mode
When the module is configured for Dual Channel Mode the module has two independent
keyers, each with an independent output. As shown in the diagram below, the background
input feeds both keyers. Alternately, the internal matte generator could be selected as the
background for either or both of the keyers. Each keyer has unique key and fill material
for keying. Output 1 provides the program out for Keyer 1. Output 2 provides the program
out for Keyer 2.
