About MultiMedia

Taken literally, the term 'MultiMedia' implies the use of many 
different kinds of communication media to convey a single message. 
However in recent years the word has earned a more specific 
meaning, namely the combination of a computer with video, audio 
and the printed page, united for the purpose of adding colour and 
depth to the information presentation process, with the help of a 
computer.

MultiMedia is the communication style of the nineties. In education 
and training, traditional learning material is brought to life, with 
video and audio technology adding a new dimension. As a 
promotional tool, the MultiMedia-based information system is a 
powerful method of retaining the browser's interest; small wonder 
that big-time retailers such as Rover cars are using this technology in 
consumer marketing programmes. Or that large institutions such as 
museums use MultiMedia stations to guide their visitors around 
buildings. The beauty of MultiMedia is that while digitally controlled 
(and therefore self-contained), it can be interactive, letting you 
explore a subject freely, accessing supporting material, images, film 
and sounds in your own time, and according to your own 
preferences.

The Acorn RISC computer, with its multi-tasking desktop and 
highly graphical user interface, is the ideal platform for MultiMedia 
work. This is emphasised by the advent of CD-ROM to the Acorn 
platform, and by the sheer quality of material which can be shown on 
the Acorn desktop. Even the traditional 'barrier' of a fixed 256-colour 
desktop palette was lifted with the appearance of the ColourCard 
graphics accelerator card.

The Eagle package

Eagle provides multi-media capabilities for both audio and video (
still and moving images). You can use Eagle either as a standalone 
package or in conjunction with other movie editing applications.
