1. An apparatus for the transmission and reception of a block coded discrete cosine transformed digital video signal having coefficients representing a DC component and a plurality of AC components of various importance comprising:

  • means responsive to said digital video signal for separating and storing like spatial frequency components of said signal;

    means for assembling said like spatial frequency components into segments which define portions of a picture;

    means for generating addresses for said segments and adding said addresses to said segments;

    means for modulating said segments for transmission;

    means for demodulating said modulated segments upon reception;

    a second means coupled to said demodulating means for storing said like spatial frequency components responsive to said addresses; and

    means responsive to said addresses and coupled to said second storing means for reconstructing from said like spatial frequency components said block coded discrete cosine transformed digital video signal.
