ABSTRACT:
A method for calling up information about current radio and television programs wherein desired signals are transmitted together or separately with decodable additional information signals. The method includes the steps of selecting from the additional information signals that information which is directly or indirectly linked to time information. The selected information is compared with a time period which can be predetermined and within which the current time and/or the time assigned to the current program occurs. The information corresponding to this time period is then displayed on a display device of a receiving device which receives the desired signals and additional information signals. The information is displayed in response to depressing a call up key of an associated receiving device or remote controller one or more times, such that at least two fields selected from the group consisting of start time, stop time, title, and remaining run time are displayed on a portion of the display device, while another portion of the display device displays information associated with the desired signals of a current channel which the receiving device is tuned to.
