We combine full audio and video recording in the conference room with ZOOM webinar in HD quality. Remotely controlled cameras enable combinations of views and make online participants feel the atmosphere in the conference. Duplex audio transmission can broadcast questions and comments from online participants in the conference room, which significantly increases interactivity. We offer comprehensive online conference management with chats, Q&A, polls, quizzes, and recording of the conference in HD quality, available one day after the conference. The recording as well as the presentations are stored in a user-protected section of the web and visible only for registered participants.
