On-Screen Display (OSD)
SAA55xx
19 DISPLAY
The display section is based on the requirements for a
Level 1.5 WST Teletext. There are some enhancements
for use with locally generated OSDs.
The display section reads the contents of the Display
memory and interprets the control/character codes. From
this information and other global settings, the display
produces the required RGB signals and Video/Data (Fast
Blanking) signal for a TV signal processing device.
The display is synchronised to the TV signal processing
device by way of horizontal and vertical sync signals
provided by external circuits (Slave Sync mode). From
these signals all display timings are derived.
