Abstract

The present interactive recording and playback technique provides the ability to archive the content, the discussions and the metadata of a meeting or similar event; then aggregate, search and annotate across this data; and finally edit, combine, or split various recordings to create new presentations. This interactive recording and playback technique provides rich productivity and innovation that is unavailable today.

Claims

1. A computer-implemented process for recording a multi-media event and reformatting the captured data into a universal format for playback, comprising the process actions of:

simultaneously recording multiple data tracks in multiple formats and from multiple sources, wherein each data track is independent from the other data tracks and operates in parallel; and

publishing the captured multiple data tracks in multiple formats from multiple data in a universal format.

2. The computer-implemented process of claim 1 wherein the universal format is accessible using only a web browser and a media player that can be embedded in the web browser.

3. The computer-implemented process of claim 1 wherein the published tracks are indexed using multiple indices and a master timeline.

5. The computer-implemented process of claim 1 wherein at least some of the captured multiple data tracks are image or video data captured with a panoramic camera and wherein the image data is published as a panoramic image.

6. The computer-implemented process of claim 1 wherein one or more tracks of the published multiple data tracks in the universal format are fully editable.

7. The computer-implemented process of claim 3 wherein one or more of the published tracks can be selected for replay using one or more of the multiple indices.

8. The computer-implemented process of claim 3 wherein the multiple indices comprise a meeting content index that indexes when content presented in the web conference changes and a speaker index that indexes when a speaker in the web conference changes.

4. The computer-implemented process further comprising replaying portions of the selected tracks of the published multiple data tracks in the universal format.

9. A computer-implemented process for playing back tracks of data in multiple formats and simultaneously captured from multiple sources and converted into a universal format comprising the process actions of:

selecting tracks of data simultaneously captured from multiple sources and in multiple formats and converted into a universal format, wherein each data track is independent from the other data tracks and operates in parallel; and

playing each of the selected tracks in a synchronized manner using a web browser and a media player that is embeddable in the web browser.

10. The computer-implemented process of claim 9 wherein perceived playback quality of the played selected tracks is dynamically detected and adjusted to provide improved playback quality by playing only portions of the selected tracks.

11. The computer-implemented process of claim 9 wherein playback quality is automatically adjusted by selecting which of the selected tracks can be replayed given an available amount of processing bandwidth.

12. The computer-implemented process of claim 9 wherein the selected tracks are stored on a server and wherein the selected tracks are played on a client in a synchronized manner.

13. The computer-implemented process of claim 9 wherein the selected tracks are stored on one or more clients and wherein the selected tracks are played on a client in a synchronized manner.

14. The computer-implemented process of claim 9 wherein portions of the selected tracks can be edited by a timeline editor that can edit the order of the selected tracks and content editors that can edit the content of the selected tracks

15. A system for capturing data from multiple sources in multiple formats for a web conference and replaying portions of the captured data in a universal format comprising:

a capture module for capturing data in the form of audio, video and meeting content presented in the web-conference in its most native format;

a recording management module that coordinates publishing of the data in the native format to the universal format;

a publishing module for converting the captured data in a universal format into a format that can be played back using a web browser; and

a playback module that comprises a web browser.

16. The system of claim 15 further comprising an editing module for editing the data in the universal format.

17. The system of claim 15 wherein the capture module further comprises:

a user interface for allowing a user to prescribe the parameters for the capture of the data;

a meeting content capture module for capturing meeting content at a client and a server on a network; and

an audio-video capture module for capturing audio and video at a client and on a server on a network.

18. The system of claim 15 wherein the publishing module further comprises:

a preprocessing module that automatically merges and synchronizes the captured data to a common timeline;

a core publishing module that publishes the data in a universal format and produces multiple indexes to access the published data using the common timeline.

19. The system of claim 18 wherein the publishing module automatically generates the captured data in a universal format, comprising converting electronic slides with animation into a web-renderable format;

converting any imaging document into non-scaled scrollable graphics;

rendering image slides at full fidelity without color banding;

converting files used in application sharing to WMV format;

converting annotations to slides into a scalable device independent rendering instructions; and

converting poll slides into a DHTML and VML format.

20. The system of claim 15 wherein the publishing module publishes the data in the background in a manner so as not to interfere with a user performing other operations using the user interface.
