Synchronizing audio frames in conference calls
A recently granted patent (Publication Number: US11888911B1) outlines a method for audio synchronization in conference settings. The method involves receiving an audio stream associated with a conference at a device joined to the conference and receiving broadcast messages from two or more devices also joined to the conference. These broadcast messages contain audio synchronization values that help identify the audio frame of the conference stream. By utilizing this method, the device can output the correct audio frame of the conference stream, ensuring synchronization among multiple devices.
Furthermore, the patent details the use of different networks for receiving the audio stream and broadcast messages, such as a first network for the audio stream and a second network, like Bluetooth Low Energy (BLE), for the broadcast messages. The method also includes the use of one-way communication protocols for transmitting these messages. Additionally, the patent covers scenarios where devices are physically co-located and the transmission of broadcast messages containing audio synchronization values. Overall, this patent provides a comprehensive approach to audio synchronization in conference environments, enhancing the user experience and ensuring seamless communication among multiple devices.
