APPLICATIONS
The 5420 module can be utilized in many ways to take advantage of its versatility. Some
keying tasks that can be performed by the 5420 include the following:
• Fixed or animated station and channel ID
• Copyright protection
• Emergency standby notification
• Gateway for downstream keys and masks from a graphic workstation
• Custom full-field test patterns/zone plates
The module can operate in DSK mode, DSK w/Preview, or Fill/Key mode. Examples of
common applications are given here.
DSK Mode
When the module is configured for DSK mode, a serial digital signal from a device such as
a Master Control switcher can be connected to the input and a graphic or logo from a PC
workstation can be inserted over the background to provide the final video as shown in
the example below. The PGM outputs can be fed to the transmitter and other destinations
and PVW outputs are available for monitoring.
