Abstract
A teletext receiving apparatus for providing the latest information whereby only the latest information received when the information is irregularly changed includes a teletext decoder, first and second memories storing first data representative of old data and second data indicative of currently provided data and providing selected the first and second data, respectively, to a comparator for comparing the first data with the second data and a control signal generator for converting parallel data generated by the comparator into serial data, integrating the serial data to produce integrated data and limiting the integrated data with respect to a predetermined direct current level so as to provide a first control signal. In receiving the teletext, the previously received information is compared with new information and, if new information has been received, only the new information is displayed on a monitor. When new information is not received, i.e., when the latest information is identical to older information, one of a television mode or a video cassette recorder mode is provided.
