Abstract
The present invention relates to an apparatus for the digitization of videofrequency television signals making it possible to improve the subjective definition of known systems using a non-orthogonal structure of points and to obviate the disadvantages of said system structure. This apparatus comprises on reception an analog-digital converter by high speed sampling corresponding to the full definition of the processed spectrum followed by an inhibitor of one sample out of every two and on reception, a conventional decoder, whose analog output signal is added to the other part of the spectrum resulting from a logic processing of the original binary train or stream.
