CODING DEVICE AND METHOD, DECODING DEVICE AND METHOD AND TRANSMISSION SYSTEM Russian patent published in 2008 - IPC H04N5/92 H04N7/30 G06T5/00 

FIELD: information technology.

SUBSTANCE: in a wavelet transformation process, there is filtering with increment on lines, with a defined number of lines, as a result of which data coefficients for one line, corresponding the component of the lowest band, is generated in form of an increment. In the first time there is processing for line number 1 to line number 7, of coefficient C1 of the upper band component, coefficient C2 and coefficient C3, and coefficient Ca of the lower band component. Coefficient Cb and coefficient Cc, are generated at level 1 division, and at level 2 division. Coefficient C4 of the upper band component and coefficient C5 of the lower band component are additionally generated from coefficient Ca, coefficient Cb and coefficient Cc. These coefficients are reconfigured in order from the lower band to the upper band, and are transmitted to a synthesis filter. The synthesis filter filters the coefficients in the order in which they were transmitted. Images are generated and output.

EFFECT: coding with compression and decoding data images and output of decoded data images with little delay.
