Abstract
A high-efficient coding apparatus and method for compressing a digital video signal such as a color television signal, by dividing the digital video signal into a plurality of sub-bands, formatting the video signal of each sub-band into blocks per every plurality of picture elements, performing an orthogonal transform to each formatted block and coding coefficients obtained by the orthogonal transform.
