Two methods of transmitting serial data in World System Teletext (WST) format are available. These are the independent data line or ‘Packet 31’ method, and the page format technique. For universal application in a subscription Teletext environment the receiving equipment must be able to accept both forms of transmission. The Multistandard acquisition circuit CIDAC (SAA5250) or CMOS Interface for Data Acquisition and Control, is available to simplify the receiver design.
