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 programmable 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. The new teletext decoder is I**2C bus controlled; therefore it is easy to integrate into any digitally controlled I**2C bus system. The modular nature of the I**2C bus architecture allows the system designer to add to or delete from his or her system various function blocks. The teletext decoder can be treated as one of these blocks.
