オーディオシステム
Document Type and Number:
Japanese Patent JP6712153
Kind Code:
B2
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) x 0.125 < 1 is assured.
