Introduction

The TPU 2735 is specified to handle Level-1-Teletext in formation (in Germany: Videotext) as it is transmitted to day by the TV broadcast stations in Great Britain, Germany and other European countries. The TPU 2735 is part of the DIGIT 2000 digital TV system and works in conjunction with the other VLSI circuits and processors of this system. This makes the Teletext adapter designed with the TPU 2735 very simple and economic (see Fig. 1–1).
