Abstract
The invention relates to a method for measuring the receiver-side bit error rate of the transmission path of a DVB transmission system in which the data stream to be transmitted is channel-coded on the transmitter side by a Reed-Solomon coder and on the receiver side channel-decoder by a corresponding Reed-Solomon decoder. According to the method, a test data stream is fed in on the transmitter side and the Reed-Solomon coder is switched off so that the receiver-side decoder recognizes a data stream with non-correctable errors and allows the same to reach the output uncorrected. The bit error rate is then determined from the uncorrected test data stream.
