Patent Images
1. A method to be executed at least in part in a computing device for capturing a presentation during an online conference, the method comprising:
- initiating a hidden instance of a presentation viewer;
capturing presentation content from the hidden presentation viewer;
capturing annotations from the presentation;
combining the captured presentation content and corresponding annotations;
encoding the combined presentation and annotations into a video file; and
storing the video file for subsequent playback of the presentation true to its original form.

Abstract
Presentations during an online conference are captured for subsequent playback. An instance of a presentation viewer is deployed to capture the presentation. Annotations and timing data are captured separately. The presentation with the annotations is recorded through a video encoding codec in a desired format, while timing and similar data is stored as metadata. Multiple presentations may be recorded separately to conserve resources. The recordation and the metadata can be subsequently played back to a requesting user.

17. A computer-readable storage medium with instructions stored thereon for capturing a presentation during an online conference, the instructions comprising:
-
at a client device facilitating the online conference for a participant, initiating a hidden instance of a presentation viewer synchronously rendering the presentation; capturing presentation content from the hidden presentation viewer; capturing annotations from the presentation; encoding the captured presentation and annotations into a video file employing a timer-driven frame-sampling scheme at a screen capturing codec; recording presentation timing data from the presentation; recording the timing data as metadata; and storing the video file and the corresponding metadata for subsequent playback of the presentation. - View Dependent Claims (18, 19, 20)
