Abstract

In some aspects, the disclosure is directed to methods and systems for providing a hybrid low power, high bandwidth media transport protocol between media sinks and media sources by splitting control and synchronization commands to a low power communication interface, and media data to a high bandwidth unidirectional communication interface. Media sinks need not transmit via the high bandwidth unidirectional communication interface, reducing power consumption, which may be particularly beneficial for small devices with limited battery capacity such as wireless earbuds.

Claims (40)

1. A system comprising:

a first media sink comprising a first communication interface and a second communication interface, the first communication interface in communication with a media source and a second media sink via a first communication medium, the second communication interface in communication with the media source via a second communication medium, the second communication medium having a higher bandwidth than the first communication medium, wherein the first media sink is configured to:

receive, with the first communication interface via the first communication medium, first synchronization information from the second media sink, the first synchronization information indicative of a first one or more time periods for the media source to transmit a media segment to the second media sink via the second communication medium and a second one or more time periods for the second media sink to respond to the media source via the first communication medium;

aggregate the first synchronization information from the second media sink with second synchronization information indicative of a third one or more time periods for the media source to transmit the media segment to the first media sink via the second communication medium and a fourth one or more time periods for the first media sink to respond to the media source via the first communication medium; and

forward, with the first communication interface via the first communication medium, the first synchronization information from the second media sink to the media source in the aggregated first and second synchronization information.

2. The system of claim 1 , wherein the second one or more time periods are subsequent to the first one or more time periods.

3. The system of claim 1 , wherein the first media sink is further configured to transmit a response to the media source during the fourth one or more time periods, the response comprising an acknowledgement of successfully received data from the media source during the third one or more time periods.

4. The system of claim 1 , wherein the first media sink is further configured to transmit a response to the media source during the fourth one or more time periods, the response comprising a negative acknowledgement indicating an absence of successfully received data from the media source during the third one or more time periods.

5. The system of claim 1 , wherein each time period is equal in duration.

6. The system of claim 1 , wherein time periods of the third one or more time periods are different in duration from time periods of the fourth one or more time periods.

7. The system of claim 1 , wherein the first communication interface uses less power than the second communication interface.

8. The system of claim 1 , wherein the first media sink is further configured to receive, with the first communication interface via the first communication medium, a notification from the second media sink indicating the second media sink has not received the media segment within the second one or more time periods.

9. The system of claim 8 , wherein the first media sink is further configured to forward, with the first communication interface via the first communication medium to the media source, the notification from the second media sink indicating the second media sink has not received the media segment within the second one or more time periods.

10. A method comprising:

receiving, with a first communication interface of a first media sink via a first communication medium, first synchronization information from a second media sink, the first synchronization information indicative of a first one or more time period for a media source to transmit a media segment to the second media sink with a second communication interface via a second communication medium and a second one or more time periods for the second media sink to respond to the media source via the first communication medium, the second communication medium having a higher bandwidth than the first communication medium;

aggregating, by the first media sink, the first synchronization information from the second media sink with second synchronization information indicative of a third one or more time periods for the media source to transmit the media segment to the first media sink via the second communication medium and a fourth one or more time periods for the first media sink to respond to the media source via the first communication medium; and

forwarding, with the first communication interface of the first media sink via the first communication medium, the first synchronization information from the second media sink to the media source in the aggregated first and second synchronization information.

11. The method of claim 10 , wherein the second one or more time periods are subsequent to the first one or more time periods.

12. The method of claim 10 , further comprising:

transmitting, with the first communication interface of the first media sink via the first communication medium, a response to the media source during the fourth one or more time periods, the response comprising an acknowledgement of successfully received data from the media source during the third one or more time periods.

13. The method of claim 10 , further comprising:

transmitting, with the first communication interface of the first media sink via the first communication medium, a response to the media source during the fourth one or more time periods, the response comprising a negative acknowledgement indicating an absence of successfully received data from the media source during the third one or more time periods.

14. The method of claim 10 , wherein each time period is equal in duration.

15. The method of claim 10 , wherein time periods of the third one or more time periods are different in duration from time periods of the fourth one or more time periods.

16. The method of claim 10 , wherein the first communication interface uses less power than the second communication interface.

17. The method of claim 10 , further comprising:

receiving, by the first media sink with the first communication interface via the first communication medium, a notification from the second media sink indicating the second media sink has not received the media segment within the second one or more time periods.

18. The method of claim 17 , further comprising:

forwarding, by the first media sink with the first communication interface via the first communication medium to the media source, the notification from the second media sink indicating the second media sink has not received the media segment within the second one or more time periods.

19. A system comprising:

a first media sink comprising a first communication interface and a second communication interface,

the first communication interface in communication with a media source via a first communication medium and a second media sink via the first communication medium, the second communication interface in communication with the media source via a second communication medium, the second communication medium having a higher bandwidth than the first communication medium, wherein the first media sink is configured to:

transmit, with the first communication interface via the first communication medium, first synchronization information to the second media sink, the first synchronization information indicative of a first one or more time periods for the media source to transmit a media segment to the first media sink via the second communication medium and a second one or more time periods for the first media sink to respond to the media source via the first communication medium,

wherein the second media sink is configured to:

aggregate the first synchronization information from the first media sink with second synchronization information indicative of a third one or more time periods for the media source to transmit the media segment to the second media sink via the second communication medium and a fourth one or more time periods for the second media sink to respond to the media source via the first communication medium; and

forward, with the first communication interface via the first communication medium, the first synchronization information from the first media sink to the media source in the aggregated first and second synchronization information; and

wherein the first media sink is further configured to:

transmit, with the first communication interface via the first communication medium, a notification to the second media sink indicating the first media sink has not received the media segment within the second one or more time periods,

wherein the second media sink is further configured to forward, to the media source, the notification indicating the first media sink has not received the media segment within the second one or more time periods.

20. The system of claim 19 , wherein the first communication interface uses less power than the second communication interface.
