| Abstract | By the year 2000, shopping, recording music and answering the phone might all be done while sitting at home, pressing a few buttons and issuing a few oral commands. The above scenario will likely be realised in the near future. The key is the most powerful digital invention of the era - the digital video disc, or DVD. It combines all the functions of a laser disc, a compact disc, a compact disc with read only memory, a recordable compact disc and an erasable compact disc. The comparatively high cost of the new digital video systems is likely to drop significantly with economies of scale. |
