Methods and systems for managing simultaneous data streams from multiple sources
A system and method for managing simultaneous data streams from multiple sources is provided. At least one paired audio device within the system, is a managing device and coordinates the audio playback presented in each paired audio device. In this way, each device can produce an audio playback associated with different streams simultaneously. In some examples, the managing device is one of the two devices or a peripheral device, e.g., a smartphone. In some examples, each data stream contains data used to generate a priority level for each data stream. The managing device can allow a data stream having a higher priority level or the data stream with a detected change to “barge-in” causing the playbacks of each device to be associated with a different data stream. Additionally, each device is capable of assuming the role of “stream scanner” to prevent uneven power consumption between the devices within the system.
1 . A device for managing data streams from multiple sources, the device comprising: an acoustic transducer; and circuitry comprising: a radio configured to scan for multiple data streams; and at least one processor configured to:
detect an isochronous data stream from a first audio source, and
in response to identifying a change in the isochronous data stream while causing audio playback from a data stream from a second audio source, automatically initiate audio playback at the acoustic transducer using the isochronous data stream, wherein identifying the change in the isochronous data stream includes identifying that an audio stream of the isochronous data stream has changed from an inactive state to an active state;
wherein the device is wireless connected to a second device, and in response to identifying the change in the isochronous data stream, the device causes the second device to initiate audio playback using the isochronous data stream;
wherein the audio playback using the isochronous data stream at the device and the second device is performed in synchrony.
2 . The device of claim 1 , wherein the data stream from the second audio source is another isochronous data stream.
3 . The device of claim 1 , wherein the data stream from the second audio source is a Bluetooth Classic Audio data stream.
4 . The device of claim 1 , wherein the isochronous data stream is a Bluetooth Low Energy Audio data stream and wherein the isochronous data stream includes audio data encoded using the Low Complexity Communications Codec (LC3).
5 . The device of claim 1 , wherein the audio playback from the data stream from the second audio source is stopped and/or muted prior to initiating audio playback using the isochronous data stream.
6 . The device of claim 1 , wherein the initiating of the audio playback using the isochronous data stream includes mixing audio data from the isochronous data stream with audio data from the data stream from the second audio source.
7 . A method for managing data streams from multiple sources, the method comprising:
scanning, via a radio, for multiple data streams;
detecting, via at least one processor, an isochronous data stream from a first audio source;
identifying, via the at least one processor, a change in the isochronous data stream while causing audio playback from a data stream from a second audio source, wherein identifying the change in the isochronous data stream includes identifying that an audio stream of the isochronous data stream has changed from an inactive state to an active state;
in response to identifying the change, automatically initiating audio playback at an acoustic transducer using the isochronous data stream;
in response to identifying the change in the isochronous data stream, initiating audio playback using the isochronous data stream at a remote device;
wherein the audio playback using the isochronous data stream and the audio playback at the remote device is performed in synchrony.
8 . The method of claim 7 , wherein the data stream from the second audio source is another isochronous data stream.
9 . The method of claim 7 , wherein the data stream from the second audio source is a Bluetooth Classic Audio data stream.
10 . The method of claim 7 , wherein the isochronous data stream is a Bluetooth LE Audio data stream and wherein the isochronous data stream includes audio data encoded using the Low Complexity Communications Codec (LC3).
11 . The method of claim 7 , wherein the audio playback from the data stream from the second audio source is stopped and/or muted prior to initiating audio playback using the isochronous data stream.
12 . The method of claim 7 , wherein initiating audio playback using the isochronous data stream includes mixing audio data from the isochronous data stream with audio data from the data stream from the second audio source.
