<p>A system is described which supplies auxiliary information to users wherein the auxiliary information supplements information obtained from received broadcast programs. The system includes units (16a-16c) which respectively enable the users to receive broadcast programs (14) from a plurality of stations (10). Broadcast programs, for which auxiliary information is desired by a user, are marked by the respective unit (16a-16c) by recording data in response to the actuation of a switch. The data which is recorded identifies the station from which each marked program was received along with the time and date at which the reception of each marked program occurred. This recorded data is transmitted (19) to a central location (20) where it is used to identify the marked programs and to identify stored auxiliary information related to these marked programs. The identified auxiliary information is then sent to the user from the central location (21).</p> |
