Title:
AUDIO SYSTEM DATA SYNCHRONIZATION METHOD AND AUDIO COMPONENT
Document Type and Number:
WIPO Patent Application WO/2022/156081
Kind Code:
A1
Abstract:
The present application provides an audio system data synchronization method and an audio component. The method comprises: a first device receives, in the nth cycle, an audio data packet sent by an audio data source, and determines whether the reception is successful; a second device receives, in the nth cycle, the audio data packet sent by the audio data source, and determines whether the reception is successful; and if the first device and/or the second device fail/fails to receive the audio data packet, the device that fails to receive the audio data packet in the first device and the second device sends a first special acknowledgement packet in the nth cycle, the first special acknowledgement packet comprising a first additional field and an NAK packet; after receiving the NAK packet, the audio data source is enabled to resend an audio data packet in the (n+1)th cycle; and after receiving the first additional field, the other device is enabled to stop sending a signal in the nth cycle, and synchronously receives, in the (n+1)th cycle, the audio data packet resent by the audio data source with the device that fails to receive the audio data packet.
