The STV5342is a HCMOS integrated circuit which performs all the processing of logical data within a 625 lines system teletext decoder. It is designed to operate in conjunction with one-chip : the SAA5231 integrated chip which extracts Teletext information embedded in a composite video signal. Up to 4 pages of display data can be stored in internal
memory. A complete system also comprises a microprocessorcontrolling theSTV5342 via a 2-wires serial bus. An on-chipROM memory contains the character sets. The STV5342 performs automatic selection ofone of upto sixnatural languages.Data bytes may be decoded in either 7-Bit plus parity or in full 8-Bit formats. The chip set also supports
facilities for reception and display of higher-level protocol data.
