ABSTRACT:
A 3.times.3 sub-band coding-decoding circuit for coding and decoding video signals and a method thereof includes: a horizontal dividing section, a vertical dividing section, a vertical synthesizing section, and a horizontal synthesizing section. The transmitting signals are divided into a horizontally compressed low band, a horizontally compressed medium band and a horizontally compressed high band. From these three bands, first to sixth bands (LL-HL) are formed. At the receiving section, the six bands are restored into three bands, i.e., a vertically restored low band, a vertically restored medium band and a vertically restored high band. Then the three restored bands are finally restored to the form before the coding by expanding the horizontal components and by adding them together.
