    摘要: A digital tuner in a broadcasting receiving unit outputs audio data at a sample rate of Fs+dr (Hz), and an ASRC rate-converts audio data to audio data at a sample rate of Fs+ds (Hz) and transmits the resulting audio data to an audio processing unit. A DAC in the audio processing unit analog-converts the received audio data at an output rate of Fs+da (Hz) and outputs the resulting audio data to a speaker. The sample rate Fs+ds and the output rate Fs+da are synchronized with a SYNC transmitted from the broadcasting receiving unit to the audio processing unit on a 125 ms cycle. For the sample rate Fs+ds and the output rate Fs+da, a relationship of (da−ds)×0.125

    摘要: The invention relates to a method for acoustically emitting audio broadcasting signals in a vehicle, wherein audio broadcasting signals can be transmitted into the vehicle and received there over a first and at least a second reception path, wherein the first reception path is evaluated by means of at least one criterion parameter on the basis of an audio broadcasting signal that can be received over the first reception path, and the second reception path is likewise evaluated by means of a criterion parameter on the basis of the audio broadcasting signal that can be received over the second reception path. During an emission of the audio broadcasting signal over one of the reception paths, a preparation phase for preparing a switchover from the current reception path to the other reception path is started on the basis of a comparison of the criterion parameter of the current reception path to a first threshold value (S1). In the preparation phase, the criterion parameter of the current reception path is compared to a second threshold value (S2) that is lower than the first threshold value (S1), and an examination of the switchover to the other reception path is performed if the criterion parameter of the current reception value is below the second threshold value (S2).
