2.13. Display
The display is based on the requirements for a Level
1.5 Teletext and powerful additional enhanced OSD
features.
The display circuit reads the contents and attribute set-
tings of the display memory and generates the RGB
data for a TV back-end signal processing unit.
The display can be synchronized to external H/V sync
signals (slave mode) or can generate the synchroniza-
tion signals by itself (master mode). The display can be
synchronized to 50 Hz as well as to 60 Hz systems.
Interlaced display is supported for interlaced sync
sources and non-interlaced ones.
