Abstract

An information handling system includes a redirection module and an audio/video module. The redirection module receives an audio data frame and an image data frame, analyzes the image data frame for a trigger event. In response the trigger event being detected in the image data frame, the redirection module replaces the audio data frame with a silent audio data frame and provides the silent audio data frame to the audio/video module. Otherwise the redirection module provides the audio data frame to the audio/video module. The audio/video module receives and transmits either the audio data frame or the silent audio data frame.

Claims

1. A method comprising:

receiving, at a redirection module of an information handling system, an audio data frame and an image data frame;

analyzing the image data frame for a trigger event;

in response to detecting the trigger event in the image data frame, replacing the audio data frame with a silent audio data frame; and

providing either the audio data frame or the silent audio data frame to an audio/video module.

2. The method of claim 1, further comprising:

determining whether a modified image output has been selected;

modifying the image frame in response the modified image output being selected; and

providing the modified image frame with the silent audio data frame to the audio/video module.

3. The method of claim 2, wherein modifying the image r ne includes producing a still image frame.

4. The method of claim 1 wherein modifying the image ne includes blurring a portion of the image frame.

5. The method of claim 1, further comprising:

receiving a second audio data frame and a second image data frame;

analyzing the second image data frame to determine whether the trigger event is in the second image data frame; and

providing the second audio data frame and the second image data frame to the audio/video module instead of the silent audio data frame in response to the trigger event being detected in the second image data frame.

6. The method of claim 1, further comprising:

providing a visual output indicator to a user in response to the trigger event being detected, wherein the visual output indicator notifies the user that the silent audio data frame is being provided to the audio/video module.

7. The method of claim 1, wherein the event trigger is a gesture by the user.

8. An information handling system comprising:

a redirection module configured to receive an audio data frame and an image data frame, to analyze the image data frame for a trigger event, in response to the trigger event being detected in the image data frame to replace the audio data frame with a silent audio data frame and to provide the silent audio data frame, otherwise to provide the audio data frame; and

an audio/video module configured to communicate with the redirection module, the audio/video module configured to receive and transmit either the audio data frame or the silent audio data frame.

9. The information handling system of claim 8, wherein the redirection module is further configured to determine whether a modified image output has been selected, to modify the image frame in response the modified image output being selected, and to provide the modified image frame with the silent audio data frame to the audio/video module.

10. The information handling system of claim 9, wherein the modified image frame is a still image frame.

11. The information handling system of claim 9, wherein the modified image frame includes a blurred a portion of the image frame.

12. The information handling system of claim 8, wherein the redirection module is further configured to receive a second audio data frame and a second image data frame, to analyze the second image data frame to determine whether the trigger event is in the second image data frame, and to provide the second audio data frame and the second video frame to the audio/video module instead of the silent audio data frame in response to the trigger event being detected in the second video frame.

13. The information handling system of claim 8, further comprising:

a notification module configured to communicate with the redirection module, the notification module is configured to provide a visual output indicator to a user in response to the trigger event being detected, wherein the visual output indicator notifies the user that the silent audio data frame is being provided to the audio/video module.

14. The information handling system of claim 8, wherein the event trigger is a gesture by the user.

15. A method comprising:

receiving, at a redirection module of an information handling system, an audio data frame and an image data frame;

determining whether a trigger event is detected in either the image data frame or the audio data frame;

in response to detecting the trigger event, redirecting the audio data frame from an audio/video module to a voice input module; and

providing a silent audio data frame to the audio/video module.

16. The method of claim 15, further comprising:

determining whether a modified image output has been selected;

modifying the image data frame in response the modified image output being selected; and

providing the modified image data frame with the silent audio data frame to the audio/video module.

17. The method of claim 16, wherein modifying the image data frame includes producing a still image data frame.

18. The method of claim 16, wherein modifying the image data frame includes blurring a portion of the image data frame.

19. The method of claim 15, further comprising:

receiving a second audio data frame and a second image data frame;

determining whether the trigger event is detected in either the second image data frame or the second audio data frame; and

providing the second audio data frame and the second image data frame to the audio/video module instead of the silent audio data frame in response to the trigger event being detected.

20. The method of claim 15, further comprising:

providing a visual output indicator to a user in response to the trigger event being detected, wherein the visual output indicator notifies the user that the silent audio data frame is being provided to the audio/video module.
