US 11,375,574 B2 · Latency reduction

Abstract

Reduced Advanced Audio Distribution Profile (A2DP) latency on a link between a source and a pair of headphones may be achieved by improving the quality of the link between secondary and primary and establishing a direct link between the source and secondary to mitigate the link quality issues of the source and primary link. In one example, this involves receiving, via a first receiver, packets from a source on a first wireless connection, determining, by the first receiver, that a first packet received via the first wireless connection has an error, establishing a second connection between the first receiver and a second receiver, and establishing a third connection between the second receiver and the source. In particular, the first receiver may be configured as a primary True Wireless Stereo (TWS) Bluetooth device and the second receiver may be configured as a secondary TWS Bluetooth device.

Dependent claims

An apparatus comprising:

a first receiver wirelessly coupled to a source configured to output packets, the first receiver configured as a primary True Wireless Stereo (TWS) Bluetooth device;
and
a second receiver wirelessly coupled to the first receiver, the second receiver configured as a secondary TWS Bluetooth device;
wherein the first receiver is configured to establish a first connection with the source and a second connection with the second receiver, receive a first packet from the source on the first connection, and determine whether the received first packet has an error;
wherein the second receiver is configured to establish a third connection with the source and receive the first packet from the source;
wherein the first receiver is further configured to determine whether the second receiver received the first packet in response to the determination that the first packet has the error.

An apparatus comprising:

first means for transceiving wirelessly coupled to a source configured to output packets, the first means for transceiving configured as a primary True Wireless Stereo (TWS) Bluetooth device;
and
second means for transceiving wirelessly coupled to the first means for transceiving, the second means for transceiving configured as a secondary TWS Bluetooth device;
wherein the first means for transceiving is configured to establish a first connection with the source and a second connection with the second means for transceiving, receive a first packet from the source on the first connection, and determine whether the received first packet has an error;
wherein the second means for transceiving is configured to establish a third connection with the source and receive the first packet from the source;
wherein the first means for transceiving is further configured to determine whether the second means for transceiving received the first packet in response to the determination that the first packet has the error.

3 more elements

A non-transitory computer-readable medium comprising instructions that when executed by a processor cause the processor to perform a method, the method comprising:

establishing a first connection between a source and a first receiver, the first receiver configured as a True Wireless Stereo (TWS) Bluetooth configured device;
receiving a first packet from the source by the first receiver;
determining, by the first receiver, the first packet has an error;
establishing a second connection between the first receiver and a second receiver, the second receiver configured as a TWS Bluetooth configured device;
establishing a third connection between the second receiver and the source;
receiving, by the second receiver, the first packet from the source;
and
determining whether the second receiver received the first packet in response to the determination that the first packet has the error.
