Abstract:
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.

Claim (Index 1):
A method of Bluetooth (BT) synchronized media streaming, comprising:\n configuring a plurality of BT media devices in a scatternet chain including a first, second and third BT media device each including a BT controller comprising a processor running a stored time synchronization algorithm and having a local clock and a network clock; said first BT media device receiving a stream of encoded media data from a BT digital media stream sending device; said time synchronization algorithm of said first BT media device formatting at least a first BT media packet including said encoded media data, an address for said second BT media device, and time synchronization information for said second BT media device comprising said first BT media packet's play start time including a delay time, and a cumulative clock drift counted thus far in said chain; said first BT media device transmitting said first BT media packet to said second BT media device; said time synchronization algorithm of said second BT media device formatting at least a second BT media packet including said encoded media data, an address for said third BT media device, and updated time synchronization information for said third BT media device including said second BT media packet's play start time including a time of said local clock of said second BT controller, said second BT controller clock's drift and said delay time value, and said cumulative clock drift counted thus far in said device chain now including said clocks of said second BT media device, said second BT media device transmitting said second BT media packet to said third BT media device, and said time synchronization algorithms beginning synchronized playing of said stream of encoded media data including said first BT media device playing after said delay time is reached, said second BT device playing after said first BT media packet's play start time is reached, and said third BT media device playing after said second BT media packet's play start time is reached.
