Graphics Overlaying the Video
The DCH100 can generate graphics that overlay the video programming or fill the
entire television screen. Common examples include on-screen menus (such as the
On-Screen Diagnostics) and EPG. The DCH100 overlays these graphics whenever
you open a menu or scroll through a program grid.
On-screen graphics are available for all DCH100 video outputs.
