摘要

P the invention relates to the transmission of an analog signal audio frequency during the time characteristics of the synchronization pulses of a signal of the television / p & & p & the process of the transmission comprises a coding of the sound signal consisting of the converted into words of n bits has a frequency twice the frequency - line and a emit for each synchronization pulse four n-bit words corresponding to the different samples, which introduces redundancy in two and a decorrelation between the various samples. The method comprises a brief, which consists in comparing the two representations of the same sample, issued when two pulses of syncronisation and is chosen as a function of the result of the comparison, a representation for each sample. / p & & p & the invention applies in particular during storage in a video disk. / p
