Abstract

Techniques are provided for converting live presentations into electronic media and managing captured media assets for distribution. An exemplary system includes capture devices that capture media assets of live presentations comprising a session, including image data of sequentially presented visual aids accompanying the live presentations and audio data. Each capture device has an interface for real-time image data marking of the image data for identification of individual images and session marking of the image data for demarcation of individual presentations of the session. A centralized device processes the captured media assets and automatically divides the captured media assets into discrete files associated with the individual presentations based on the session markings. An administrative tool manages the processed media assets to produce modified presentations and enables modification of the visual aid images identified by the image data markings. A production device formats the modified presentations for distribution on distribution media.

Claims

1. A method of capturing a live presentation, comprising:

capturing displayed media from a display device which displays said displayed media for viewing by an audience during a live lecture or conference presentation;

during the live lecture or conference presentation, detecting one or more changes in said displayed media, wherein the change includes at least one of;

a change in image data, an animation, user input, and display of video data;

recording an audio portion of a speaker'"'"'s presentation during the live lecture or conference presentation; and

in response to said detected one or more changes in displayed media, automatically synchronizing at least one change in displayed media with the audio portion of the speaker'"'"'s presentation.

2. The method of claim 1, wherein said displayed media is captured using a video graphics array (VGA).

3. The method of claim 1, further comprising:

distributing, by a content distribution engine, said captured displayed media and said recorded audio portion of the speaker'"'"'s presentation to a user.

4. The method of claim 3, wherein distribution of said captured displayed media and said recorded audio portion includes at least one of:

streaming video, streaming audio, and electronic file transmission.

5. A system for capturing a live presentation, comprising:

a display device configured to display media for viewing by an audience during a live lecture or conference presentation;

a capture device configured to capture said displayed media during the live lecture or conference presentation;

a processing device configured to detect, during the live lecture or conference presentation, one or more changes in said displayed media, wherein the change includes at least one of;

a change in image data, an animation, user input, and display of video data; and

a recording device configured to record an audio portion of a speaker'"'"'s presentation during the live lecture or conference presentation, wherein

the processing device is further configured to, in response to said detected one or more changes in displayed media, automatically synchronize at least one change in displayed media with the audio portion of the speaker'"'"'s presentation.

6. The system of claim 5, wherein said displayed media is captured using a video graphics array (VGA).

7. The system of claim 5, further comprising:

a content distribution engine configured to distribute said captured displayed media and said recorded audio portion of the speaker'"'"'s presentation to a user.

8. The system of claim 7, wherein the content distribution engine is configured to distribute said displayed projected media and said recorded audio portion using at least one of:

streaming video, streaming audio, and electronic file transmission.

9. The system of claim 5, wherein at least the display device and the capture device are a single device.

10. A non-transitory computer readable recording medium configured to store program code executable by one or more processing devices, wherein the program code, when executed by the one or more processing devices, is configured to perform a method for capturing a live presentation, the method comprising:

capturing displayed media from a display device which displays said displayed media for viewing by an audience during a live lecture or conference presentation;

during the live lecture or conference presentation, detecting one or more changes in said displayed media, wherein the change includes at least one of;

a change in image data, an animation, user input, and display of video data;

recording an audio portion of a speaker'"'"'s presentation during the live lecture or conference presentation; and

in response to said detected one or more changes in displayed media, automatically synchronizing at least one change in displayed media with the audio portion of the speaker'"'"'s presentation.

11. The non-transitory computer readable recording medium of claim 10, wherein said displayed media is captured using a video graphics array (VGA).

12. The non-transitory computer readable recording medium of claim 10, wherein the method further comprises:

distributing, by a content distribution engine, said captured displayed media and said recorded audio portion of the speaker'"'"'s presentation to a user.

13. The non-transitory computer readable recording medium of claim 12, wherein distribution of said captured displayed media and said recorded audio portion includes at least one of:

streaming video, streaming audio, and electronic file transmission.
