ABSTRACT:
A subband coding method and encoding/decoding system suitable for a high definition television which is possible to compress data more effectively. Frequency band of input data is analyzed into a high-band component and a low-band component in the two-dimensional diagonal direction, the diagonal low-band component is analyzed again into orthogonal high-band component and low-band component and the diagonal high-band component and the orthogonal high-band component are coded, and then the orthogonal low-band component is continuously analyzed until it has a desired size by repeating the previous analysis procedures.
