TPU 2735

The TPU 2735 is specified to handle Level-1-Teletext information (in Germany: Videotext) as it is transmitted today 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. 11).

The TPU 2735 is an N-channel VLSI MOS circuit, housed in a 40-pin Dil plastic package and contains on a single silicon chip the following functions: one-chip solution of the Teletext processing (except for external RAM) ghost compensation to eliminate the effects of ghost pictures due to reflections reduced access time is provided for the Teletext pages by receiving and storing up to eight pages in one go up to 32 stored pages automatic language-dependent character selection switchover facility PAL/NTSC/D2MAC full level one features (FLOF) support level 1.5 Spanish Teletext support largely compatible to the TPU 2732/33
