Objective specification
Enhanced TV microcontrollers with
On-Screen Display (OSD)
SAA567x; SAA569x
23.5.18 S
MOOTHING
To improve the appearance of the display, the SAA567x;
SAA569x family of devices incorporates a smoothing
algorithm to insert extra pixels for all character sizes other
than normal size (see Fig.38). Smoothing is available in
both TXT and CC modes.
MMR 87E4H bit 4enablessmoothinginsinglepagemode
and for Page A in doublewindow mode. MMR 87E4H bit 5
enables smoothing for Page B in double window mode.
The appearance of special graphics characters and
fringed characters cannot be improved with the smoothing
algorithm.
