AI-generated Abstract
The Great Courses successfully transitioned its extensive library of educational content to digital formats using Elemental Server, a powerful transcoding solution. Faced with the challenge of modernizing delivery platforms and converting a vast amount of video material, The Great Courses leveraged Elemental Server's high-quality video processing capabilities and technical support to improve accessibility and revenue streams. By converting high-definition content to various web-friendly formats, the company expanded its reach to a broader audience, fulfilling the growing demand for lifelong learning.

Transcoding, the conversion between different representations of Web content at an intermediate proxy, can ameliorate mismatches between the complex content provided by an origin server, and the limited bandwidth to, or display capabilities of, a Web client. Existing transcoding systems use implicit information, such as the HTTP Content-type, to control when and how they convert between representations. This approach must balance the risk of losing important information against the intended goal (such as bandwidth reduction), often without sufficient information to make the optimal choice.

Abstract The web is emerging as the primary data dissemination and e-commerce mechanism. Users access the Internet from a wide variety of devices with different resource constraints in terms of their processing, storage, network and display capabilities. Users are not only accessing the Internet from traditional desktops, but they are also using mobile devices such as palmtops and laptops as well as newer consumer devices such as webtops and navigation systems.

The aim of this tutorial is to present the challenges and opportunities that online education offers our Universities today, and to illustrate them with the description of the design and implementation of an online course in neural networks. There are many issues involved in the process of providing traditional courses from different disciplines using the Internet; the majority of current

The large diffusion of e-learning technologies represents a great opportunity for underserved segments of population. This is particularly true for people with disabilities for whom digital barriers should be overstepped with the aim of reengaging them back into society to education. In essence, before a mass of learners can be engaged in a collective educational process, each single member should be put in the position to enjoy accessible and customized educational experiences, regardless of the wide diversity of their personal characteristics and technological equipment. To respond to this demand, we developed LOT (Learning Object Transcoder), a distributed PHP-based serviceoriented system designed to deliver flexible and customized educational services for a multitude of learners, each with his/her own diverse preferences and needs. The main novelty of LOT amounts to a broking service able to manage the transcoding activities needed to convert multimedia digital material into the form which better fits a given student profile. Transcoding activities are performed based on the use of Web service technologies. Experimental results gathered from several field trials with LOT (available online at http://137.204.74.83/∼lot/) have confirmed the viability of our approach.
This session will use three activities/discussions to help you learn to evaluate and increase instructor and student presence in online courses.
