DESCRIPTION
The STV5346 decoder is a computer-controlled
teletext device including an 8 page internal mem-
ory. Data slicing and capturing extracts the teletext
information embedded in the composite video sig-
nal. Control is accomplished via a two wire serial
I2C bus ®. Internal ROM provides a character set
suitable to display text using up to seven national
languages. Different ROM versions will support
several national character sets. Hardware and soft-
ware features allow selectable master/slave syn-
chronization configurations. The STV5346 also
supports facilities for reception and display of cur-
rent level protocol data.
