Patent number: 11042349Abstract: An electronic device that coordinates a playback operation is described. In particular, an interface circuit in the electronic device may calculate, based on differences between transmit times when packets were transmitted by a second electronic device and receive times of the packets, relative drift as a function of time between a clock in the interface circuit and a second clock in the second electronic device. Then, the interface circuit may adjust, based on the relative drift, a clock circuit that provides the clock to eliminate the relative drift, and may determine a remaining time offset between the clock and the second clock. Next, the interface circuit may modify a future time when the second electronic device is to perform the playback operation based on the remaining time offset to determine a corrected future time, and may transmit information to the second electronic device specifying the corrected future time.Type: GrantFiled: April 8, 2019Date of Patent: June 22, 2021Assignee: B&W Group Ltd.Inventors: Leo Lay, Adrian Harold Chadd, Haisong Wang, Shiwei Zhao, Li Li, Gaylord Yu
