Synchronization Of A Split Audio, Video, Or Other Data Stream With Separate Sinks

A source device, comprising;

• a source clock generator;
• a radio frequency (RF) communication module configured to generate a plurality of communication packets that each include data of a data stream and a respective timestamp generated by the source clock generator, wherein each communication packet of the plurality of communication packets is configured to be received by a designated output device of a plurality of output devices;
• and
• an antenna configured to transmit the plurality of communication packets;
• wherein each output device of the plurality of output devices receives a designated portion of the transmitted communication packets, whereby the output devices generate substantially synchronized output streams.

A method for synchronizing data output by a plurality of output devices, comprising:

• performing steps (a)-(f) in each output device of the plurality of output devices to produce substantially synchronized output streams,
• (a) receiving a communication packet from a source device, wherein the communication packet includes data and a source clock timestamp;
• (b) generating a local clock signal synchronized with a source clock signal of the source device;
• (c) decoding the data using a codec;
• (d) subtracting at least one delay and the source clock timestamp from a current value of the local clock signal to generate a local latency value;
• (e) determining a difference between a desired latency value and the local latency value;
• and
• (f) adjusting a rate of a clock signal of the codec according to the determined difference.

A method in a source device for synchronizing output devices, comprising;

• and
• transmitting the plurality of communication packets;
• wherein each output device of the plurality of output devices receives a designated portion of the transmitted communication packets, whereby the output devices generate substantially synchronized output streams.
