Abstract
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<1 is assured.
