Satellite multicasting improves educational information delivery

21.03.2006


A project supported by the European Space Agency has combined satellite multicasting techniques and improved content management to enhance information delivery for education .



The use of information and communications technology in schools all over Europe is on the increase. Although the various Ministries of Education have set up networks that offer recommendations on content, as well as advice and support to educators, challenges still remain in the take-up of information technology in schools.

The ESA supported project SchoolCast aims to resolve at least some of these issues by having developed a system that improves the way in which schools access information from the Internet. The key is in improving the management of content, multicasting specific multimedia rich content to groups and sub-groups of schools and then providing feedback to stakeholders about precisely how schools are using this content.


Improved content management

SchoolCast allows the agencies responsible for schools, such as school boards or similar government institutions, to select the most relevant content from the Internet, organise it to suit their own needs and ensure that legal questions on the use of the material are resolved.

The content can then be transmitted via satellite at night, when it is less expensive. Schools equipped with satellite antennas receive the content and store it for use in the classroom the following day.

Multicasting saves on satellite capacity

The SchoolCast content is multicast to schools via a satellite network. Multicasting enables more efficient delivery of data to multiple destinations on a network. Particularly with video-streaming, multicasting via satellite can translate into a significant saving of resources.

Not only does SchoolCast take advantage of a satellite network but the system architect has designed the system to ’push’ the most frequently used websites out to the users, where they are cached locally. This approach also greatly reduces the amount of satellite capacity being used.

Consortium

The project has been made possible through a consortium of four commercial companies and two public institutions. ATiT Ireland is the Prime Contractor of the ESA supported project; Global Communication and Services GmbH from Austria is responsible for the multicasting software; Web-Sat Ltd. from Ireland provides the two-way Internet via satellite network; Intel® IT Innovation from Ireland lend support in the non-satellite take-up of the service.

The National Centre for Technology in Education (NCTE) is the main stakeholder and both evaluates the service and provides content; HEAnet are a key test user of the network.

Field Trials

SchoolCast has been field tested and validated in educational environment. ’Speed and reliability’ were the impressions of teachers taking part in the trials. Teachers can benefit from materials and sites that have been sourced by their peers with content that fits perfectly into their local teaching needs.

The service has proven itself to be both user-friendly and transparent. The service will import any content which can be packaged for multicast. The market potential for SchoolCast has been assessed and numerous opportunities exist throughout Europe.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
