Abstract: A mobile communication appliance (10) sets up a connection to a coordination device (20) via a first mobile radio link (12, 21). This is used to register a request for participation in a radio-based video chat. The mobile communication appliance (10) receives a participation confirmation and records a video signal. The latter is transmitted to a video server (30) via a second mobile radio link (13) for storage. Finally, the mobile communication appliance (10) transmits a message to the coordination device (20), with the message containing a reference to the video signal stored on the video server (30). This reference is forwarded to a transmission station (40), from which the video signal is broadcast as a radio signal (45).
