Order requests for playing audio contents and/or video contents are transmitted by way of communication transmission apparatus (3) via a telecommunication network (2) to a computer-based central unit (1). The central unit (1) determines one of several geographically distributed play units (5, 6, 7) which are remote from the central unit (1) and are separate from the communication transmission apparatus (3), on account of details which are transmitted with the order requests, e.g. an identification or a location detail of a play unit (5, 6, 7), or a location detail of a mobile communication transmission unit (3), for playing the audio contents and/or video contents. The audio contents and/or video contents are transmitted from the central unit (1) as a continuous data flow to the selected play unit (5, 6, 7), and are played there via loudspeakers (51, 61, 71) or displays (52, 72). Several play units may be activated by users via their communication transmission apparatus (3) via a common central unit (1), without different address information and/or contact information of the play units (5, 6, 7) having to be used. Moreover, the play units (5, 6, 7) do not have to be provided with a receiver module (11) for the receiving and the processing of order requests for audio contents.
