Over the past few years, with the rapid adoption of broadband communication and advances in multimedia content capture and delivery, Web-based meetings and lectures, also referred to as e-meeting and e-lecture, have become popular among businesses and academic institutions because of their cost savings and capabilities in providing self-paced education and convenient content access and retrieval. In fact, the technological achievements in capture, analysis, access, and delivery of e-meeting and e-lecture media have already resulted in several working systems that are currently of regular usage. This paper gives an overview of existing work as well as state-of-the-art in these two research areas which are bound to affect the way we teach, learn, and collaborate.
