Abstract

Method of adapting intended to permit information processed according to the CEPT 1 standard to be displayed on a telematic terminal of the type provided for application of the CEPT 2 standard. This method provides translation of the colours of one palette according to the CEPT1 standard into one of the colours of another palette according to the CEPT2 standard, as a function of the luminance of the colours of the first palette, an approximation of the CEPT 1 alphanumeric character matrices until a matrix according to the CEPT 2 standard is obtained and transcription of the change in coloration of an animated image by flicking from one colour to another for each of the individually coloured alphanumeric or graphic elements involved in the image in question.
