VLSI circuits for teletext (Videotext) and Viewdata
Abstract
The application of existing teletext decoders by the German television industry was investigated. Rapid development of circuits, based on the UK standard for videotext and viewdata, was stressed. Interactive videotext and broadcast videotext were considered. Dynamically redefinable character sets are discussed and the circuit design of a video display generator is presented. Modem and picture attributes are treated. The possibilities for VLSI of teletext decoder circuits are established. International standards of teletext data transmission are called for.
