DPCM. The simplest form of predictive compression operates at the pixel level with a technique called differential PCM (DPCM). In DPCM, we compare adjacent pixels and then transmit only the difference between them. Because adjacent pixels often are similar, the difference values have a high probability of being small and they can safely be transmitted with fewer bits than it would take to send a whole new pixel. 3, record 1, English, - differential%20pulse%2Dcoded%20modulation%20coding

Le codage MIC différentiel (MIC D) consiste à ne transmettre d'une image que les éléments qui ont changé par rapport à la précédente. 3, record 1, French, - codage%20DPCM

Le codage DPCM (Delta PCM ou modulation Delta) permet de réduire l'encombrement en codant la différence entre les valeurs successives échantillonnées et non plus les valeurs elles-mêmes. Le nombre de bits nécessaire pour le codage est moindre. 1, record 1, French, - codage%20DPCM
