Abstract
A graphical source ID display has a plurality of display regions aligned with respective columns of source selector buttons. Each display region has a bit-map representation, either iconic or textual, that identifies the source associated with that column. The display regions may further be backlit. The bit-map representation is entered into a display controller by an operator during setup, the display controller providing the bit-map representations to the appropriate display regions.
