Teletext Decoders--Keeping up With The Latest Technology Advances

The new generation teletext decoder, unlike its predecessor introduced in 1976, is user programmable under the control of a general purpose microcomputer or microprocessor. The new decoder is programinable to operate in the Vertical Blanking Interval (VBI) or full field teletext mode of operation. It can, simultaneously, acquire multi-pages resulting in a much faster system response time.
