Abstract: A process for annotating a video in real-time on a mobile device. The process may include creating one or more markers, allowing a user of the mobile device to annotate the video while one or more users within a group of users are annotating the streaming video in real-time. The process may include receiving a selection from the user for which he or she seeks to annotate within the video. The process further includes displaying a text box for a frame or range of frames selected by the user seeks for annotation, and receiving a submitted text box from the user and propagating the annotations within the submitted text box to one or more users within the group in real-time.

Abstract: A system and method to enable fine-grained, contextual annotations of streaming videos by one or more users, prioritizing the use of screen space on mobile devices by allowing users to draw or place threaded comments while utilizing a touch-based interface, reducing distractions caused by a* cluttered interface. By enabling the user to control annotations beginning at a particular timestamp within the streaming video, the present invention optimizes screen real estate on mobile devices efficiently. Contextual commenting is enabled using a combination of perspectives, which highlight the parts of the video being annotated, while dimming out the rest of the screen elements and flexible extension of a user's comments across one or many frames of the streaming video. Using a simple touch-based interface the present invention is intuitive and further enables the user to select the vicinity around which he or she wishes to increase sensitivity or have finer control.
