  • Patent number: 9916835
    Abstract: A digital wireless audio transmission system having a wireless receiving unit for wirelessly receiving a high-frequency signal. An HF analysis unit analyzes the received high-frequency data, detects errors in the transmission within a time window, and outputs the received data and first items of information in respect of the detected errors. A decoding unit converts/decodes the received high-frequency data into audio data. An error detection unit checks errors in the conversion of the decoding unit within a previously established time window and outputs second items of information in respect of errors during decoding of the received high-frequency data. An error rate is determined based on the first and second items of information. If the error rate exceeds a first threshold value then no audio signal is outputted. Only if the error rate falls below a second value, lower than the first value, is an audio output is then again effected.
