Changes in the management of information in audio-visual archives following digitization: Current and future outlook

This article attempts to offer an overview of the current changes that are being experienced in the management of audio-visual documentation and those that can be forecast in the future as a result of the migration from analogue to digital information. For this purpose the documentary chain will be used as a basis to analyse individually the tasks that are more significantly affected by this documentary and technological revolution. Although this article will focus on the management of television audio-visual information and the changes in ordinary documentation activities, the results may also be applied to other institutions working with the moving image. Automatic classification, automatic indexing, voice and video recognition and automatic generation of thesauri are some of the elements considered as potential and/or feasible methods to deal with and understand the information management activity of television channels.
