摘要： The invention relates to a method for the transmission of an asynchronous data stream, containing useful data, via a synchronous data bus which is arranged to transmit data frames in time multiplex. The invention is characterized in that the asynchronous data stream is converted into a synchronous, continuous data stream by means of a converter circuit, that within the data frames a selectable number of storage locations is provided for the useful data of the asynchronous data stream, that a variable number of useful data can be assigned to the individual data frames by the converter circuit and in dependence on the speed of the asynchronous data stream, and that protocol data is assigned to the individual data frames by means of the converter circuit, each time in a predetermined position within the data frames, which protocol data contains information as regards the number of useful data present in the relevant data frame.
