How digitalisation changed it?
Digitalisation appeared in all industries: print, music (audio) and film (movie). Digital formats were discovered and storing techniques were invented. Slowly all media types started to converge to the same medium: The multi-media personal computer (PC). That’s what we call media convergence. All industries strived with recording and archiving. So compression technologies (zip, JPEG, MPEG, HDTV) and distribution channels evolved: CD-Digital audio, DVD, Blue-ray, till we reached the point where the compressed data and the speed of the internet networks become comparable, and no physical storage was used any more.
Content editing also evolved, and from specialist studios we experienced PC accessible multi-media applications that gave the whole process in our hands in all media. First we experienced how we edit our „type-writer style” manuscripts to word-processed, later Desk-top published (DTP) publications. Graphic, audio and video editing followed this multi-media revolution, that was deeply accelerated by enthusiastic early inventor scholars who pioneered in using those techniques in education themselves.
Nowadays the different forms of content development are living together: Publishing, converting, on-line content (text audio, video) industry, Educational technology centers in schools or universities, educational technology technicians or simple ICT professionals still help scholars to produce or to „digitise” content. But slowly more and more teachers, trainers learn and use digital tools to produce and organise digital content themselves. This course is made for them.
