For "Super Audio CD" (SACD) the DSD signals are losslessly coded, using framing, prediction and entropy coding. Besides the efficiently encoded signals, a large number of parameters, i.e. the side- information, has to be stored on the SACD too. The side information comprises the prediction filter coefficients and the probability table which have been used for encoding, and which should be transmitted to the decoder. The smaller the storage capacity that is required for the side- information, the better the overall coding gain is. Therefore coding techniques are applied to the side-information too so as to compress the amount of data of the side information. The frames can be segmented, each segment having its own set of filter coefficients and probability table.

Pour les "Super Audio CD" (SACD), on code les signaux DSD par verrouillage de trame, prédiction et codage entropique. En plus des signaux efficacement codés, il faut stocker un grand nombre de paramètres ou informations latérales dans le SACD. Ces informations latérales comprennent les coefficients de filtre de prédiction et la table de probabilité qui ont été utilisées pour le codage, et qui devraient être transmises au décodeur. Plus la capacité de codage requise faible, plus le gain global de codage est bon. C'est pourquoi on applique également les techniques de codage aux informations latérales, de manière à compresser le volume de données contenues dans lesdites informations. Il est possible de segmenter les trames, chaque segment possédant son jeu de coefficients de filtre et sa table de probabilité en propre.
