Abstract
Described are systems and methods that allow a video conference participant to efficiently review semantically meaningful events within the video streams shared by their peers. Because participants are engaged in real-time communication, it is important to provide tools that let them quickly jump back to past events that were shown previously, not requiring them to manipulate a standard video timeline. Our techniques thus find meaningful events in the video stream such as scrolling pages, moving windows, typing text, etc. Using these techniques, a participant can then easily go back to e.g. the last PDF page shown by a peer, while still listening to the live audio.
