Abstract

In one embodiment, an apparatus can include: a status detector configured to determine a status associated with an input stream; a parameter controller configured to adjust a parameter in response to a change in the status; and a rendering controller configured to receive the input stream, and to provide a rendered stream in response to the input stream and the parameter.

Claims

1. An apparatus, comprising:

a configuration controller configured to provide predetermined settings in response to a user input and default settings, wherein the default settings are received from a server, and the user input is configured to change the predetermined settings from the default settings;

a status detector configured to determine a status associated with an input stream that is received by the status detector, wherein the status detector is configured to use a voice identification, an emergency indication, and a detected user action, in the status determination based on the predetermined settings;

a parameter controller configured to adjust a parameter in response to a detected change in the status from the status detector, wherein the adjusted parameter is identified in the predetermined settings; and

a rendering controller configured to receive the input stream, and to provide a rendered stream in response to the input stream and the adjusted parameter.

2. The apparatus of claim 1, comprising a device configured with an Internet protocol, IP, application, wherein the device comprises the configuration controller, the status detector, the parameter controller, and the rendering controller.

3. The apparatus of claim 1, wherein the change in status comprises a change from a secondary participant to a primary participant in a virtual talk group.

4. The apparatus of claim 1, wherein the voice identification is provided in association with the input stream to identify an originator of audio from another apparatus coupled to the server.

5. The apparatus of claim 1, wherein the emergency indication is provided in association with the input stream from another apparatus coupled to the server.

6. The apparatus of claim 1, wherein the detected user action comprises invocation of a voice replay buffer.

7. The apparatus of claim 1, wherein the parameter comprises at least one of a volume setting and a stereo setting.

8. The apparatus of claim 1, wherein the input stream is received via a multicast network.

9. The apparatus of claim 1, wherein the rendered stream comprises a generated version of the input stream, the input stream comprising IP signaling.

10. A method, comprising:

storing predetermined settings in an endpoint in response to a user input and default settings, wherein the default settings are received from a server, and the user input is configured to change the predetermined settings from the default settings;

receiving an input stream at a status detector and a rendering controller in the endpoint;

adjusting a parameter when a status associated with the input stream changes, wherein the status is determined in the status detector using a voice identification, an emergency indication, and a detected user action, based on the predetermined settings; and

providing a rendered stream in response to the input stream and the adjusted parameter, wherein the adjusted parameter is identified in the predetermined settings.

11. The method of claim 10, wherein the voice identification is provided in association with the input stream to identify an originator of audio from another endpoint coupled to the server.

12. The method of claim 10, wherein the emergency indication is provided in association with the input stream from another endpoint coupled to the server.

13. The method of claim 10, wherein the detected user action comprises invocation of a voice replay buffer.

14. The method of claim 10, wherein the adjusting the parameter comprises changing at least one of a volume setting and a stereo setting.

15. The method of claim 10, wherein the receiving the input stream in the endpoint comprises receiving the input stream from a multicast network, the input stream comprising Internet protocol, IP, signaling.

16. A system, comprising:

a plurality of endpoints coupled via a network; and

an interoperability server coupled to each of the plurality of endpoints, wherein at least one of the endpoints comprises;

a configuration controller configured to provide predetermined settings in response to a user input and default settings, wherein the default settings are received from the interoperability server, and the user input is configured to change the predetermined settings from the default settings;

a status detector configured to determine a status associated with an input stream that is received by the status detector, wherein the status detector is configured to use a voice identification, an emergency indication, and a detected user action, in the status determination based on the predetermined settings;

a parameter controller configured to adjust a parameter in response to a detected change in the status from the status detector, wherein the adjusted parameter is identified in the predetermined settings; and

a rendering controller configured to receive the input stream, and to provide a rendered stream in response to the input stream and the adjusted parameter.

17. The system of claim 16, wherein the voice identification is provided in association with the input stream to identify an originator of audio from another endpoint coupled to the server.

18. The system of claim 16, wherein the emergency indication is provided in association with the input stream from another of the plurality of endpoints coupled to the interoperability server.

19. The system of claim 16, wherein the detected user action comprises invocation of a voice replay buffer.

20. The system of claim 16, wherein the parameter comprises at least one of a volume setting and a stereo setting.

21. The system of claim 16, wherein the network comprises a multicast network, the input stream comprising Internet protocol, IP, signaling.

22. An endpoint, comprising:

a processor; and

a memory that includes instructions, wherein the endpoint is configured for;

storing predetermined settings in response to a user input and default settings, wherein the default settings are received from a server, and the user input is configured to change the predetermined settings from the default settings;

receiving an input stream in the endpoint at a status detector and a rendering controller;

adjusting a parameter when a status associated with the input stream changes, wherein the status is determined in the status detector using a voice identification, an emergency indication, and a detected user action, based on the predetermined settings; and

providing a rendered stream in response to the input stream and the adjusted parameter, wherein the adjusted parameter is identified in the predetermined settings.
