tesselated TV

For the RESULT project, Robin Mudge developed Tesselated Television, a method that could take the hundreds of individual video learning objects, used in the on-line learning system, and turn them into a regular Television program for transmission over the air.
Example video learning object link.

The word tessellation comes from the Latin ‘tessela’ meaning ‘…to fit together exactly, leaving no spaces’, and the concept of TTV is based upon such a definition. However, there is one major difference. Normally, the tesselated pattern (usually called a mosaic) is made up of pieces identical in shape. In TTV, the shapes, (video learning objects) used to create the mosaic ( linear television program) are not identical – herein lies the challenge.
By utilizing existing resources TTV will provide tailor-made programming that:
*    spans all age groups
*    is entertaining
*    is suitable for a broad range of ability levels
*    has the potential to be curriculum specific
*    is subject related
*    can be used in conjunction with other modes of learning.
The segments and components that have been carefully chosen from existing material, are fused together to form a structured and dynamic ‘whole’ program or scheduled sequence – the ultimate in 21c technological recycling and at the heart of the ‘Produce Once Use Many Times’ production philosophy. By using this technique, the same material can be used many times by making only small changes to individual bits of the ‘whole’. In this way a program could have many different versions encompassing different abilities or learning styles.

The Virtual Campus

It is well known that much valuable learning occurs through informal conversation and meetings within the University and School campus. Digital Slate aims to facilitate the same kind of campus-based environment to enable valuable informal learning amongst students attending on-line course and who are geographically remote from each other. Even though students may be attending courses at different times, in different places and completing them at different paces, the extensive communication and collaboration tools provided by the digitalSLATE Learning Management System enable these students to conduct informal conversations and meetings with each other. However, just providing the tools of communication is not enough to guarantee that conversations will start. Digital Slate staff manages the virtual campus environment.

The Walters Art Museum Interactive Educational TV Services

The Walters Interactive TS service delivers a series of regular live video presentations from the galleries of the Walters Art Museum for K-12 students who are unable to visit the museum in person.
These live ‘field trips’ are delivered in real time over the Internet and displayed in a classroom environment on a large screen TV or projector connected to a desk top computer. There is a ‘text based’ back channel through which students (and teachers) can ask questions of the presenters, throughout the presentation, who can then respond in an appropriate manner and in real time.
The aim is to provide an experience for the students that is ‘as good as being there’
To achieve this aim, the project has adopted a new video streaming service from LiveStream that allows the Walters to create and deliver it’s own Interactive TV Channel over the Internet; ‘Walters ITV’.
Unlike similar streaming services, LiveStream have developed a small, foolproof, camera interface (the LiveStream Broadcaster) which mounts directly onto a light weight, HD camcorder and connects it to the live channel totally wirelessly.  As Livestream says ‘the LiveStream Broadcaster is an HD live broadcasting device that works seamlessly with the New LiveStream service to deliver the industry’s first affordable unlimited ad-free HD live streaming end-to-end solution’.
The channel and live broadcast is controlled from an iPhone/iPad app, which also displays questions being asked by the students (and other viewers)
This complete hand held system allows a more mobile, fluid, informal and responsive production style to be used, more akin to actually being in the galleries than static camera positions (required for more traditional videoconferencing delivery systems) could ever deliver.
