Webcasting of Traditional Chalkboard Lectures: The EyA System - E. Canessa, C. Fonda and M. Zennaro, EURODL
In our experience, to produce rich-media presentations and videos for Internet streaming both the type of audience and their available computer/networking facilities need to be considered. In this regard it is necessary to select low-bandwidth compliant applications that can keep the video quality as high as possible, and to follow as much as possible the proposed open standards for the authoring of audio-visual presentations in order to make them visible under many platforms and operating systems. Also relevant to mention is to automate as much as possible the production of the presentations and to reduce the costs of any post-processing and editing (in terms of human resources and financial costs). The final result should be similar (or as much as closer) to a high quality learning experience for the remote audience. This is still an open technological challenge for research, in particular, in the case of the recording of traditional chalkboard lectures.
