Abstract
The present disclosure provides a wireless earbud system and an operation method thereof, the wireless earbud system minimizing the frequency of occurrence of data relay between earbuds and the delay time, and minimizing battery consumption. The wireless earbud system comprises: a source device; a first sink device receiving audio data from the source device; and a second sink device snooping the audio data transmitted from the source device, wherein, if there is data failed to be snooped by the second sink device, the first sink device may transmit a relay packet to the second sink device such that a data relay is performed.
Claims13
A wireless earbud system, comprising:
- a source device;
- a first sink device configured to receive audio data from the source device;
- and
- a second sink device configured to snoop audio data transmitted from the source device,
- wherein the first sink device is configured to transmit relay packets to the second sink device to perform a data relay operation when there is data that fails to snoop in the second sink device, and
- wherein the first sink device is further configured to:
- transmit a start control packet containing reception status information of Asynchronous Connection-Less (ACL) data received from the source device to the second sink device:
- receive a reply control packet containing reception status information of the ACL data snooped by the second sink device from the second sink device;
- determine whether the data relay operation is necessary by comparing the ACL data received from the source device and the ACL data received by the second sink device through the reply control packet;
- and
- transmit an end packet to the second sink device when the data relay operation is not necessary based on the comparison or when the data relay operation is completed.

A method of operating in a wireless earbud system, comprising:
- transmitting audio data from a source device to a first sink device;
- receiving, by the first sink device, the audio data from the source device;
- snooping, by a second sink device, audio data transmitted from the source device;
- transmitting, by the first sink device, a start control packet containing reception status information of Asynchronous Connection-Less (ACL) data received from the source device to the second sink device;
- receiving, by the first sink device, a reply control packet containing reception status information of the ACL data snooped by the second sink device from the second sink device;
- determining whether the data relay operation is necessary by comparing the ACL data received from the source device and the ACL data received by the second sink device through the reply control packet:
- transmitting, by the first sink device, a relay packet to the second sink device to perform a data relay operation when there is data that failed to snoop in the second sink device;
- and
- transmitting, by the first sink device, an end packet to the second sink device when the data relay operation is not necessary or when the data relay operation is completed.
