Abstract [en]

Scan processing is an analog electronic image manipulation technology which emerged in the late 1960's, reached its apex during the 1970's, and was made obsolete by digital computing in the 1980's. During this period, scan processing instruments such as the Scanimate (1969) and the Rutt/Etra Video Synthesizer (1973) revolutionized commercial animation and inspired a generation of experimental video artists. This paper presents a media archaeological examination of scan processing which analyzes the history and functioning of the instruments used, what sorts of possibilities they afforded their users, and how those affordances were realized with technology of the era. The author proposes the reenactment of historical media technologies as an investigative methodology which helps us understand the relation of past and present, and details a reenactment of scan processing involving the display of digitally synthesized audio signals on an analog Cathode Ray Tube vector monitor.

Abstract [en]

This dissertation investigates methods and strategies for reenacting historical sound and image synthesis instruments. A reenactment is neither a physical reconstruction nor a digital emulation, although it may involve aspects of both approaches. Rather, a reenactment explores the agencies of the persons, things, places, practices and ideas which gave rise to a specific audio/visual technology, and to the expressive possibilities which its users discovered in it. The reenactment then seeks congruences between these historical conditions and expressions, and those of our own time. In practice, the reenactment of an audio/visual instrument works through its historical conditions using modern technological means to address contemporary concerns. The results of this process could take the form of an analog instrument, a digital instrument, a hybrid device combining technologies of both, or even as an instrument of the future which does not exist yet. Regardless of its final form, the reenactment itself is an ongoing action rather than a fixed object, to be completed by persons through the practice of playing. 

Abstract [sv]

Denna avhandling undersöker metoder och strategier för att återskapahistoriska ljud- och bildsyntesinstrument. Ett återskapande är varken enfysisk rekonstruktion eller en digital emulering, även om den kaninnehålla aspekter av båda metoderna. Snarare utforskar ett återskapandede personer, ting, platser, praktiker och idéer som gav upphov till enspecifik audio/visuell teknik och de uttrycksmöjligheter som dessanvändare upptäckte i den. Återskapandet söker sedan kongruenser mellandessa historiska förhållanden och uttryck och de som råder i vår egentid. I praktiken innebär återskapandet av ett audio/visuellt instrumentatt man arbetar sig igenom dess historiska förutsättningar med hjälp avmoderna tekniska medel för att ta itu med samtida problem. Resultatet avdenna process kan ta formen av ett analogt instrument, ett digitaltinstrument, en hybrid som kombinerar teknik från båda, eller till ochmed som ett instrument från framtiden som ännu inte existerar. Oavsettdess slutliga form är själva återskapandet en pågående handling snarareän ett fast objekt, som ska fullbordas av personer genom att spela.
