Ensemble Designs 7420 HD/SD Logo Inserter - Manual (Page 6)

APPLICATIONS
The 7420 module can be used in many ways to take advantage of its versatility:
• Key still or animated station and channel ID
• Key sports or event logos and animations with associated audio clips
• Add letterbox framing for HD
• Source a virtual set background
• Custom full-field test patterns/zone plates
• One 7420 can be a source for two simultaneous Trouble “Slides”
The 7420 module can operate in Program/Preview mode, Fill/Key mode, or Dual Channel
mode. Examples of typical applications are given here.
Program/Preview Mode
When the module is configured for Program/Preview mode (the most common use), 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. The PVW outputs show what the next transition will
be.
