Many lecture recording and presentation systems transmit slides or chalkboard content along with a small video of the instructor. As a result, two areas of the screen are competing for the viewer’s attention, causing the widely known split-attention effect. Face and body gestures, such as pointing, do not appear in the context of the slides or the board. To eliminate this problem, this article ...

Even though a tremendous adoption growth-triggered by the increased broadband connections to Internet user homeshas occurred since 200 I , little is known regarding who the early adopters may be, the reasons why they adopt webcasting and what types of content wi l l be most viable for adoption. This study examined the potential factors that could help predict webcasting adoption. In particular,...

In webcasts that involve both a local and remote audience, the amount of interaction with remote participants is typically very limited. Video conferencing offers a much higher level of interactivity, but is constrained by high bandwidth requirements and poor scalability. Our research aims to bring some of the advantages of videoconferencing to ePresence, an open-source webcasting infrastructur...

In Italy, public meeting webcasts are frequently adopted by local public administrations to support the “information provision” process. This is supposed to increase the citizens’ awareness and participation to public life. In the paper, the experience gathered from the design of both the architecture of a webcasting system and the “webcast’s production and distribution process” is presented. T...

Webcasts can adopt techniques developed by television to obtain higher quality. Television production techniques, however, cannot be integrated into webcast production without considering the fundamental di erences in the underlying infrastructure. We have developed a general webcast production model composed of three stages (i.e., sources, broadcast, and transmission) to address these di erenc...
