Communication technology has a manipulative power and effect on the field of education in general. These technologies have been increasingly used in education and training for many years to meet different needs. The increased use of technology in education and training has brought new disciplines into education field. Web based distance education is one of the newest forms of education, which depends on communication and information technology. As a new and modern approach to deliver instruction, many institutions are offering both academic and non-academic web-base educational courses. In this paper, we argue that a broadcast-centric solution can be utilized to provide educational services to an entire region via Digital Video Broadcasting (DVB). This distance learning solution can provide equity access to resources for several schools of a large region or access for undergraduate and postgraduate students of a wide-spread university system. This approach includes combinations of broadcast delivery, local redistribution of content, direct access, and interactive access to the material over the broadcast infrastructure. This approach also requires that special consideration be given to the organization of content for distribution. We will discuss related issues and technologies for distance learning.
Education, as a public institution, is being redefined by technology access. There is growing consensus about the value of digital libraries of educational multimedia content 1, especially to reach populations in regions that have limited access to quantity and quality content. For these resources to be of value, teachers and students must be able to reach them. A regional digital library would provide needed content, a common language, and a central location for coordination of services. A regional education infrastructure for equity access is also needed and must be coordinated with the development of the Digital Library 1.
Digital broadcast networks, as implemented in direct broadcast satellite (DBS) 2, hybrid fiber coax (HFC) networks, and wireless terrestrial broadcast networks, are being used for delivery of digital compressed video. The emergence of the digital video broadcast (DVB) standard has added capabilities for near video on-demand (NVOD), time delay broadcast, real-time and non- real-time transactions. But applications enabled by these technologies are limited to a download model or require a return channel for direct interactivity.
