    • A method and apparatus for real-time transmission of compressed data wherein, useful data and filling data are received as a data stream with a constant data rate via a circuit-switched connection of a first communication network, the filling data contained in the data stream with the constant data rate is removed, and the useful data contained in the data stream with the constant data rate is reformatted and sent as a data stream with a variable data rate via a packet-oriented connection of a second communications network. Efficient utilization of the transmission bandwidth is accomplished by the removal of the superfluous filling data which are received in the data stream with the constant data rate via the circuit-switched connection, and the reformatting of the useful data for the data stream with the variable data rate via the packet-oriented connection. This has a particularly favorable effect 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.
    • 一种用于实时传输压缩数据的方法和装置,其中有用数据和填充数据作为具有恒定数据速率的数据流通过第一通信网络的电路交换连接被接收,所述填充数据包含在数据流中 其中恒定数据速率被去除,并且包含在具有恒定数据速率的数据流中的有用数据被重新格式化并且经由第二通信网络的面向分组的连接作为具有可变数据速率的数据流被发送。 传输带宽的有效利用是通过经由电路交换连接去除以恒定数据速率在数据流中接收的多余填充数据以及用可变数据重新格式化数据流的有用数据 通过面向分组的连接速率。 如果压缩数据的实时传输导致具有传输带宽受限的无线电接口的移动通信网络,则这具有特别有利的效果。
