  26. 26. The future of Television <ul><li>Prof. R.L. Koolhaas – Wired Aug 2004 </li></ul><ul><li>“ With the introduction of digital TV, the concept of video or audio footage will become obsolete, replaced by the generic nature of digital files.” </li></ul>
  27. 27. The future of Television: Consequences <ul><li>The following are potential consequences: </li></ul><ul><ul><li>Files will be stored and retrieved easily and, furnished with ' metadata ', also searched more effectively. The TV station will be a searchable data archive, much like a library. </li></ul></ul><ul><ul><li>Video on demand and bandwidth on demand will create a new balance between what a TV station wants its viewers to look at and what the viewer wants to watch. The TV station will be a content provider rather than a broadcaster only. </li></ul></ul><ul><ul><li>Interactivity will allow a TV station to communicate directly with its viewers, with profound implications for the kind of programs that will be produced. The TV station will be not only the mouth, but also the ears of the nation. </li></ul></ul><ul><ul><li>With the advent of digital cinema, TV and movies will simply be different resolutions of the same material, with profound implications for production, storage and distribution. </li></ul></ul><ul><ul><li>From being a specialised “manufacturer” of TV content, the digital TV station will become the central hub in a network for the production and distribution of moving images, and could take a much more widely defined cultural role. </li></ul></ul>
