Abstract

A multistandard single-chip teletext processor for application in analog and digital TV sets is described. Based on a 65C02 core with RAM and ROM on chip, an adaptive data slicer, a display controller and a number of interfaces, the new circuit allows acquisition and display of various teletext standards such as WST, CAPTION and VPS. The basic idea behind the multistandard teletext processor concept is the replacement of random logic by software. Except for a DRAM as page memory no additional chips are needed to generate an analog RGB text display decoded from an analog composite video input
