DESCRIPTION
The STV5347 teletext decoder is computer-con-
trolled. It can store either 4 teletext pages without
ghost row, or 2 teletextpageswith ghost rows. Data
slicing and capturing extracts the teletext informa-
tion embedded in the composite video signal. Con-
trol is accomplished via a two wire serial I²C bus ®.
Chip address is 22h. Internal ROM provides a
character set suitable to display text using up to
seven national languages.Hardware and software
features allow selectable master/slave synchroni-
zation configurations.The STV5347 also supports
facilities for reception and display of current level
protocol data.
