Recent trends suggest that multimedia (in particular audio and video) will increase their share of Internet traffic, and that users are becoming more and more acquainted with viewing multimedia content on their computers and mobile devices. Scholarly institutions are experimenting since several years with the distribution of video-lectures, which are generally not meant as a replacement of traditional lectures, but rather as a different kind of support of the educational process. After recalling the pioneering ideas, discussed in this chapter is the pedagogical soundness of the idea of using videos over Internet for teaching and learning. Later reviewed are the various directions that research has taken over the last 10 years to support and enhance this modality.
Chapter Preview


The possibility of using digital video for distance education was envisioned already 15 years ago when F. Tobagi (1995) built in Stanford a prototypical architecture for distributing digital video lectures. Although using (analogical) video for recording lectures had been in use for more than a decade, the digital approach was obviously superior in terms of ease of distribution of the didactic material, asynchronous and multiple simultaneous accesses. Moreover it was promising in terms of possibility for cross-referencing of learning resources.
