5.10 On Screen Display
The DMC73C167 on screen display (OSD) hardware has two separate video
RAM blocks called Line A and Line B. Both Line A and Line B can be accessed
by the CPU separately. Thus, it is possible to modify video RAM data while one
line is being accessed by the video display controller. So multiple lines are easily
displayed with the help of the display line counter which is supported by on-chip
hardware.
