Patent number: 10645663Abstract: Synchronized media streaming in a device chain including first, second and third Bluetooth media device having a controller and time synchronization algorithm. The first device formats a first media packet including received media data, second device address, and synchronization information including packet start time including a delay time and cumulative clock drift counted thus far. The second device receives the first packet and formats a second packet including the media data, third device address, updated synchronization information including the second packet's play start time, local clock time, clock drift, and a cumulative clock drift counted thus far. The second device transmits the second packet to the third device. The synchronization algorithms begin synchronized playing of the media data including the first device playing after the delay time, second device playing after the first packet's play start time, and the third device playing after the second packet's play start time.Type: GrantFiled: June 25, 2018Date of Patent: May 5, 2020Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Ram Malovany, Chen Loewy, Dotan Ziv, David Levy

Publication number: 20180324570Abstract: A network device serving two or more networks using periodic times slots for transmission events is configured to determine that one of the periodic time slots on one of the networks has or soon will collide with one of the periodic time slots on the other network by processing time stamps for events on each network. Either of the periodic time slots may be occasionally shifted by a time shift amount to avoid a collision between the periodic time slots on each network. Shifting the periodic time slots may be performed by transmitting a Bluetooth connection parameter update packet.Type: ApplicationFiled: July 13, 2018Publication date: November 8, 2018Inventors: Matan Ben-Shachar, Omri Eshel, Yuval Jakira, Liran Brecher, Dotan Ziv, Chen Loewy
