Multi-source audio broadcast to an audio sink device
View Patent ↗One embodiment sets forth a technique for managing an audio broadcast. The technique includes transmitting first access information for a first audio stream to one or more sink devices, wherein the first access information is used by the sink device(s) to play first audio content transmitted from a first source device and the first audio content is transmitted over the first audio stream. The technique also includes receiving a first request from a second source device to transmit second audio content to the sink device(s), wherein the first request comprises second access information for a second audio stream. The technique further includes transmitting the second access information to the sink device(s), wherein the second access information is used by the sink device(s) to play the second audio content transmitted from the second source device and the second audio content is transmitted over the second audio stream.
1 . A computer-implemented method for managing an audio broadcast, the method comprising:
transmitting first access information for a first audio stream to one or more sink devices, wherein the first access information is used by the one or more sink devices to play first audio content transmitted from a first source device, the first audio content being transmitted to the one or more sink devices over the first audio stream;
receiving, at a host device, a first request from a second source device to transmit second audio content to the one or more sink devices, wherein the first request comprises second access information for a second audio stream; and
transmitting the second access information from the host device to the one or more sink devices, wherein the second access information is used by the one or more sink devices to play the second audio content transmitted from the second source device, the second audio content being transmitted to the one or more sink devices over the second audio stream.
2 . The computer-implemented method of claim 1 , further comprising:
receiving a termination of the second audio stream from the second source device;
receiving a second request from a third source device to transmit third audio content to the one or more sink devices, wherein the second request comprises third access information for a third audio stream over which the third audio content is transmitted; and
transmitting the third access information for the third audio stream to the one or more sink devices.
3 . The computer-implemented method of claim 1 , wherein the first audio stream comprises a first isochronous stream and the second audio stream comprises a second isochronous stream.
4 . The computer-implemented method of claim 1 , further comprising receiving an approval of the first request prior to transmitting the second access information to the one or more sink devices.
5 . The computer-implemented method of claim 1 , wherein the first request is received via an advertisement from the second source device.
6 . The computer-implemented method of claim 1 , wherein the first access information comprises at least one of an address of the first source device or timing information associated with the first audio stream.
7 . The computer-implemented method of claim 1 , further comprising establishing a link-layer connection with the one or more sink devices prior to transmitting the first access information.
8 . The computer-implemented method of claim 1 , wherein the first access information is transmitted from the first source device to the one or more sink devices.
9 . The computer-implemented method of claim 1 , wherein the first audio stream comprises at least one of a broadcast isochronous stream or a connected isochronous stream.
10 . The computer-implemented method of claim 1 , wherein the one or more sink devices comprise at least one of a portable speaker, a headphone, or a mobile device.
11 . One or more non-transitory computer readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:
transmitting first access information for a first audio stream to one or more sink devices, wherein the first access information is used by the one or more sink devices to play first audio content transmitted from a first source device, the first audio content being transmitted to the one or more sink devices over the first audio stream;
receiving, at a host device, a first request from a second source device to transmit second audio content to the one or more sink devices, wherein the first request comprises second access information for a second audio stream; and
transmitting the second access information from the host device to the one or more sink devices, wherein the second access information is used by the one or more sink devices to play the second audio content transmitted from the second source device, the second audio content being transmitted to the one or more sink devices over the second audio stream.
12 . The one or more non-transitory computer readable media of claim 11 , wherein the instructions, when executed, further cause the one or more processors to perform the steps of:
receiving a termination of the second audio stream from the second source device; and
retransmitting the first access information for the first audio stream to the one or more sink devices, wherein the first access information is used by the one or more sink devices to play third audio content transmitted from the first source device, the third audio content being transmitted to the one or more sink devices over the first audio stream.
13 . The one or more non-transitory computer readable media of claim 11 , wherein the instructions, when executed, further cause the one or more processors to perform the step of receiving an approval of the first request prior to transmitting the second access information to the one or more sink devices.
14 . The one or more non-transitory computer readable media of claim 11 , wherein the first audio stream comprises a connected isochronous stream and the second audio stream comprises a broadcast isochronous stream.
15 . The one or more non-transitory computer readable media of claim 11 , wherein the first access information comprises at least one of an address of the first source device or timing information associated with the first audio stream.
16 . The one or more non-transitory computer readable media of claim 11 , wherein the first request comprises a context associated with a user of the second source device.
17 . The one or more non-transitory computer readable media of claim 11 , wherein the first request is received from a mobile application on the second source device.
18 . The one or more non-transitory computer readable media of claim 11 , wherein the one or more sink devices comprise at least one of a portable speaker, a headphone, or a mobile device.
19 . The one or more non-transitory computer readable media of claim 11 , wherein the first source device comprises at least one of a smart microphone, a mobile phone, a tablet computer, a personal computer, a laptop computer, a media player, a smartwatch, or a television.
20 . A system, comprising:
a memory that stores instructions, and
a processor that is coupled to the memory and, when executing the instructions, is configured to:
transmit first access information for a first audio stream to one or more sink devices, wherein the first access information is used by the one or more sink devices to play first audio content transmitted from a first source device, the first audio content being transmitted to the one or more sink devices over the first audio stream;
receive, at a host device, a first request from a second source device to transmit second audio content to the one or more sink devices, wherein the first request comprises second access information for a second audio stream; and
transmit the second access information from the host device to the one or more sink devices, wherein the second access information is used by the one or more sink devices to play the second audio content transmitted from the second source device, the second audio content being transmitted to the one or more sink devices over the second audio stream.
