Abstract
A personal computer receives a teletext signal. A television broadcast signal received by a TV tuner unit is converted to a composite video signal and a voice signal and are then supplied to a personal computer card. The personal computer card extracts character data with a character data extracting circuit when the input composite video signal is a teletext signal and converts such character data to the code data and supplies the code data to the personal computer for display on a liquid crystal display. Moreover, when the composite video signal is a television broadcast signal, it is converted to a digital signal with a video decoder and is then supplied to the personal computer for output to the liquid crystal display.
