How is live broadcasting with Lecture Capture different than live broadcasting through Virtual Classroom?

Live broadcasting with Lecture Capture is a one-way broadcast experience of a physical classroom lecture to remote students. Because it is a one-way broadcast, it is not an interactive experience and there is no option for interaction between viewers and instructor. By contrast, Kaltura Virtual Classroom is an interactive learning experience between instructor and students and includes dedicated tools for real-time interaction and collaboration (polls, quizzes, hand raise, whiteboards etc).
