Ways Towards a Natural Television Picture

Abstract

An objective of information technology should be to offer to human beings a representation of acoustic and visual events as natural as possible. Audio technology has approached remarkably to the objective of a natural representation of acoustic events by the introduction of compact disk technology. In video technology, comparable progress towards natural representation of pictures has not been obtained so far: The moving picture requires a bandwidth approximately 1000 times higher than studio sound, the state of the art in information technology so far did not allow a more sophisticated processing and transmission of such wideband signals, keeping economical aspects in mind. Only progress obtained recently in different fields of information technology, such as microelectronics, digital signalprocessing, display terminal technology, satellite technology, optical communications technology, and developments in this field expected in the near future, from now on allow to start with efforts to improve the quality of television picture as far as to natural representation of pictures.
