Samsung patents audio sync fix for Bluetooth broadcast streams
This filing describes a method for an electronic device to maintain stable audio connections using Bluetooth broadcast technology. It involves storing initial connection details to quickly resynchronize audio streams if the connection temporarily loses timing alignment.
In the filing’s own words
An electronic device may include communication circuitry; one or more processors; and memory storing instructions. The instructions, when executed by the one or more processors, may cause the electronic device to: receive, via the communication circuitry, information corresponding to a broadcast isochronous group (BIG) from an external electronic device, store, in the memory, the information corresponding to the BIG, based on the information corresponding to the BIG, perform, via the communication circuitry, a first synchronization operation for at least one broadcast isochronous stream (BIS) broadcast by the external electronic device, based on receiving audio data via the at least one BIS, detect a BIG asynchronous event corresponding to an asynchronous state for the BIG, and based on the BIG asynchronous event, perform, via the communication circuitry, a second synchronization operation for the at least one BIS based on the stored information related to the BIG.
What exactly they claim (claim 1)
1. An electronic device, comprising: communication circuitry; one or more processors; and memory storing instructions that, when executed by the one or processors individually or collectively, cause the electronic device to: receive, via the communication circuitry, information corresponding to a broadcast isochronous group (BIG) from an external electronic device, store, in the memory, the information corresponding to the BIG, based on the information corresponding to the BIG, perform, via the communication circuitry, a first synchronization operation for at least one broadcast isochronous stream (BIS) broadcast by the external electronic device, based on receiving audio data via the at least one BIS, detect a BIG asynchronous event corresponding to an asynchronous state for the BIG, and based on the BIG asynchronous event, perform, via the communication circuitry, a second synchronization operation for the at least one BIS based on the stored information corresponding to the BIG.
