SCALABLE INFORMATION SIGNAL, DEVICE AND METHOD FOR CODING SCALABLE INFORMATION CONTENT, DEVICE AND METHOD FOR CORRECTING ERRORS OF SCALABLE INFORMATION SIGNAL

摘要

1. An information signal with the possibility of multidimensional scaling, the components of which represent the substantial part of information - content in the form of constellations of levels in multidimensional combinations, characterized in that at least the first of the many components that carry the substantial part of information at the level of the first of the many dimensions, higher than the level of the initial dimension, where the second of the many components carrying information content appears, overlaps this second component, in which at least , the third of the many components, different from the first component, representing information content at the level of the second of the multiple coordinate sets, higher than the level of the second coordinate set, where the fourth of the many components carrying information content appears, overlaps this fourth element, where the information signal in each of the various constellations it is protected by the FEC protocol by introducing redundant information associated in such a way that each element of redundant information is dependent on the corresponding the existing component that carries the substantial part of the information in the corresponding constellation; redundant information associated with a constellation in which the first component represents information content is dependent on this first component, including the fragment that overlaps the second component, and redundant information associated with a constellation in which the third component represents information content depending on this third component, including its fragment that �
