1. A video signal compression apparatus, comprising:

  • a scanner which is operative to scan a quantized set of video frequency coefficients of an individual sub-block according to a scanning pattern which is selected from a plurality of scanning patterns to produce a set of reordered coefficients;

    an entropy coder which is operative to entropy encode the set of reordered coefficients and output an entropy encoded signal; and

    a transmitter which transmits the entropy encoded signal and a scan selection signal that is not entropy encoded,wherein the scan selection signal indicates the scanning pattern.
