The STV5346 decoder is a computer-controlled teletext device including an 8 page internal memory.Data slicing and capturing extracts the teletext information embedded in the composite video signal.Control is accomplished via a two wire serial I2C bus. InternalROM provides a character set suitable to display text using up to seven national
languages. Different ROM versions will support several national character sets.Hardwareand software features allow selectable master/slave synchronization configurations. The STV5346 also supports facilities for reception and display of current level protocol data
