Hybinar (hybrid+seminar) – web-service for production, marking up and distribution ofinteractive multimedia content in real time. Multimedia content is accessible both for live and on-demand viewing. The best way to visualize Hybinar technology is a multitrack recorder. Each informationtype (video, audio, presentation slides, closed captions, text, hyperlinks, questions,tweets) is recorded on a separate track. The information is arranged along the common vector of time (timeline).
