| 摘要 | According to the invention, useful data (N) and filler data (F) are received via a circuit-switched connection of a first communications network (ISDN), in the form of a data stream (DS1) with a constant data rate (Drk). The filler data (F) contained in the data stream (DS1) with the constant data rate (DRk) are removed and the useful data (N) contained in the data stream (DS1) with the constant data rate (DRk) are reformatted and sent via a packet-orientated connection of a second communications network (UTMS) in the form of a data stream (DS2) with a variable data rate (DRv). The advantage of the invention is that efficient use is made of the transmission bandwidth by removing the superfluous filler data received via the circuit-switched connection in the data stream (DS1) with the constant data rate and by reformatting the useful data for the data stream with the variable data rate and sending it via a packet-orientated connection. This is particularly advantageous if the real-time transmission of the compressed data leads into a mobile communications network with a radio interface which is limited in terms of transmission bandwidth. | ||||||
