摘要： In a data-transmission system, a first amount of data can be transmitted in each transmission cycle. A data generator provides a second amount of data for each transmission cycle. The first amount of data exceeds the second amount of data by a percentage. The data generator transmits the data provided by the data generator to a data processor at the data transmission rate of the data-transmission channel. The data processor processes the data received from the data generator on the data-transmission channel, delayed by the number of transmission cycles required for the data generator to respond to a command from the data processor. The data processor indicates a transmission cycle as faulty with the aid of a repeat command if an error has occurred in the data transmission, and the data generator repeats the transmission of the data of the cycle indicated as faulty upon receiving the repeat command.
