Abstract: A data-broadcasting system implemented in France by the CCETT is discussed. Employing an ordinary television channel, the system provides at least three new ancillary services, and more are under development. The first service accomplishes the automatic recording of preselected programs for any user with a keypad, memory unit and VTR; the second provides scrambling and unscrambling of a television signal as for pay TV and theater projection; and the third uses the ANTIOPE teletext system to transmit “magazines” in page form to the home viewer. If the teletext system uses time-division multiplexing with an ordinary program, subtitling in any of several languages is possible along with transmission on request of special news-flash pages. Otherwise, when magazine pages only are transmitted on the channel, a page rate of about 20,000 per minute (24 lines of 40 characters each) is possible.
