Image data transmission method

摘要

The method involves transmitting and/or storing digital data, especially image data, over a data channel, in which at least one discreet wavelet transformation is performed, which produces respectively at least two data bands from the data. The data bands produced by the discreet wavelet transformation are further processed individually and independently of the processing and transmission and/or storage of other data bands. INDPENDENT CLAIMS are also included for: (1) digital data transmission and/or storage device (2) storage element, e.g. CD-ROM or diskette (3) preparation method for digital data before storage and/or transmission (4) precoding method (5) coding method for precoded image data (6) generation method for thumbnails out of wavelet-transformed image data
