Digital image information coding method e.g. for video communication, has input signal divided into 2 partial signals for separate coding and transmission

摘要

The coding method has an input signal (X) to be coded divided into a number of partial signals (X1,X2), each corresponding to the image information for a sub-group of the image points or the image information for the full image with a reduced resolution and coded separately to provide 2 coded partial signals (X1',X2'). Also included are Independent claims for the following: (a) a coding device for digital image information; (b) a decoding device for coded image information for a digital image; (c) a coding and decoding device for image information of a digital image
