Abstract

The invention relates to a ground station (10) for generating a data stream (20) that comprises a main program and an additional program. Said ground station comprises a memory (12) that stores the additional program, which is for example a commercial, while the main program is a radio program produced in a sound studio. The ground station further comprises a multiplexer (14) with a first input (14a) for receiving the main program and a second input (14b) for receiving the additional program from the memory, and with an output. A control device (16) for controlling the multiplexer (14) switches, at a first interval, an output (14c) of the multiplexer (14) from the first input to the second input and at a second interval from the second input back to the first input, thereby inserting the additional program into the main program between the first interval and the second interval. The ground station further comprises a transmitter device (18) that is connected to the output of the multiplexer (14) on the input side and that is connected to a transmitting antenna (22) on the output side so as to provide the transmitting antenna with the data stream (20). The inventive method provides a simple means for inserting commercials into the data stream without requiring special devices in the sound studio. The ground station can easily detect at which intervals commercials were inserted. The commercials can be exchanged or updated via an optional remote maintenance device of the ground station with little effort.
