Le procédé comprend les étapes suivantes : un terminal détermine des données cibles à compresser (S101) ; le terminal détecte un type de données cible des données cibles (S102) ; le terminal détermine, selon le type de données cible, un processus cible pour la compression des données cible (S103), le processus cible étant un processus servant à effectuer une compression de données à l'aide d'un mode de compression prédéfini correspondant au type de données cible ; et le terminal appelle le processus cible pour compresser les données cibles (S104). Un processus de compression de données peut être sélectionné de manière flexible selon le type de données cible, en vue de la compression des données cibles.
