Hue angle based symbol transmission and symbol loss compensation

Disclosed among others, a method (100, 300), comprising converting (306) a sequence of symbols in a first sequence of color angles, and the advertisements (104) or effecting of displaying (103) at least a partial representation of a time sequence of primitives on a display unit (35), wherein each display element of the time sequence of primitives associated with angles of color a respective hue angle of the first series, which determines the color value of at least part of the display element. a method (100, 400, 500, 900), comprising detecting (401, 402) a sequence of samples, each comprising color angle information, or from which each hue angle information is obtainable, viewed from a on a display unit (35) is disclosed further comprising at least partial representation of a time sequence of primitives, or obtaining a such detected sequence of samples, wherein each display element of the time sequence of primitives a respective hue angle of a first series is associated with color angles, that sets the color value of at least part of the display element, and wherein the first sequence of color angles on a conversion from a first sequence of symbols is based on the at least a portion representing a first sequence of information items, and determining (403, 405-410) of a representation of the first sequence of information elements at least based on the detected Fo lge of samples. corresponding devices are disclosed further (2, 4) and computer programs for the respective embodiments of this method and system (3) with such devices (2, 4).
