Abstract

A method, apparatus, and electronic device for audio-video conferencing are disclosed. A memory may store an initial historical configuration parameter representation of an initial historical configuration parameter for a set of historical video data. A processor may determine a primary initial configuration parameter based on the initial historical configuration parameter representation. An audio-video capture mechanism may capture a current set of video data using the primary initial configuration parameter. An audio input may receive an audio trigger. A configuration control mechanism may switch automatically between the primary initial configuration parameter and a primary subsequent configuration parameter based on the audio trigger.

Claims

1. A method for audio-video shot management, comprising:

extracting a set of historical video data of a video capture mechanism that have a matching historical video subject characteristic;

determining a set of initial historical configuration parameters and a corresponding set of initial historical configuration parameter representations for the set of historical video data;

determining a current video subject characteristic from a sample image; and

comparing the historical video subject characteristic to the current video subject characteristic to determine, based on an analysis of the set of initial historical configuration parameters, a primary initial configuration parameter for the video capture mechanism to capture a current set of video data based on the set of initial historical configuration parameter representations.

2. The method of claim 1, further comprising:

determining an alternate initial configuration parameter for the video capture mechanism to capture the current video data based on the set of initial historical configuration parameter representations.

3. The method of claim 2, further comprising:

receiving a user selection of the primary initial configuration parameter.

4. The method of claim 1, further comprising:

categorizing a configuration parameter of the set of historical video data as a subsequent historical configuration parameter.

5. The method of claim 4, further comprising:

storing a subsequent historical configuration parameter representation of the subsequent historical configuration parameter; and

determining a primary subsequent configuration parameters based on the subsequent historical configuration parameter representation.

6. The method of claim 5, further comprising:

switching automatically between the primary initial configuration parameter and the primary subsequent configuration parameter based on an input.

7. The method of claim 6, wherein the input is at least one of a user input, an audio trigger, a video trigger or a motion trigger.

8. The method of claim 1, wherein the primary initial configuration parameters includes at least one of pan, tilt, zoom, or brightness.

9. The method of claim 1, wherein the current video subject characteristic is one of geographical area of interest, gender of subject, age of subject, size of subject, or number of subjects.

10. The method of claim 1, further comprising weighting the historical video subject characteristic.

11. A teleconference apparatus for audio-video conferencing comprising:

a memory;

a video capture mechanism; and

a processor configured to;

extract a set of historical video data of the video capture mechanism that have a matching historical video subject characteristic;

determine a set of initial historical configuration parameters and a corresponding set of initial historical configuration parameter representations for the set of historical video data;

determine a current video subject characteristic from a sample image; and

compare the historical video subject characteristic to the current video subject characteristic to determine, based on an analysis of the set of initial historical configuration parameters, a primary initial configuration parameter for the video capture mechanism to capture a current set of video data based on the set of initial historical configuration parameter representations.

12. The telecommunications apparatus of claim 11, wherein the processor determines an alternate initial configuration parameter based on the set of initial historical configuration parameter representations.

13. The telecommunications apparatus of claim 11, wherein the memory stores a subsequent historical configuration parameter representation of a subsequent historical configuration parameter of the set of historical video data and the processor determines a primary subsequent configuration parameter based on the subsequent historical configuration parameter representation.

14. The telecommunications apparatus of claim 11, further comprising:

a configuration control mechanism that switches automatically between the primary initial configuration parameter and the primary subsequent configuration parameter based on an input.

15. An electronic device for audio-video recording comprising:

a video capture mechanism;

a processor configured to;

extract a set of historical video data of the video capture mechanism that have a matching historical video subject characteristic;

determine a set of initial historical configuration parameters and a corresponding set of initial historical configuration parameter representations for the set of historical video data;

determine a current video subject characteristic from a sample image; and

compare the historical video subject characteristic to the current video subject characteristic to determine, based on an analysis of the set of initial historical configuration parameters, a primary initial configuration parameter for the video capture mechanism to capture a current set of video data based on the set of initial historical configuration parameter representations;

a memory that stores the primary initial configuration parameter and a primary subsequent configuration parameter;

an audio input that receives an audio trigger; and

a configuration control mechanism that switches automatically between the primary initial configuration parameter and the primary subsequent configuration parameter based on the audio trigger.

16. The electronic device of claim 15, wherein the configuration control mechanism switches automatically between the primary initial configuration parameter and the primary subsequent configuration parameter based on a video trigger.

17. The electronic device of claim 16, wherein the primary initial configuration parameter includes at least one of pan, tilt, zoom, or brightness.
