Exploring new boundaries for e-learning: multicasting via satellite

To manage successful virtual distance learning programs, education institutes should implement multimedia enriched learning materials which can be used in multiple environments/situations. This not only opens up new markets but also gives teachers and learners flexible access to rich online learning resources, leading to new pedagogic practice and giving students better preparation for the challenges in the workplace. However, several studies have reported frustrations with learners and educators due to technical problems, particularly the lack of broadband capacities. An innovative IP multicasting approach to take advantage of video and multimedia elements is described, which are commonly difficult to deliver over the Internet. The Content Conductor, an open modular framework, provides a platform for fully integrated provisioning and service management of multicast communications and allows the seamless integration of different types of hardware equipment and application software. As a result of the unique characteristics of this system, broad e-learning modalities become available and manageable.
