Fill/Key Mode

When the module is configured for Fill/Key mode, the background and key signal can be
used to supply separate Fill and Key signals to feed a Master Control switcher as an input
source, in a similar manner as a character generator. The 5420 can be genlocked to an
external reference to match the timing of the Master Control device as shown below.
