Abstract

L'invention concerne un procédé d'affichage de sous-titre, consistant : à acquérir des données de texte ayant une longueur préréglée dans un fichier de sous-titre d'une vidéo avant que la vidéo ne soit lue par un terminal ; à sélectionner des formats de codage pris en charge par le terminal pour décoder les données de texte respectivement ; à calculer des degrés de correspondance entre les données de texte après avoir été décodées dans les formats de codage et les textes et/ou les signes de ponctuation dans une table de code interne correspondante dans un stock de mots ; et à régler le format de codage ayant un degré de correspondance le plus élevé parmi les formats de codage ayant les degrés de correspondance qui sont supérieurs à une valeur préréglée comme format de décodage par défaut du fichier de sous-titre pour décoder le fichier de sous-titre lorsque la vidéo est lue par le terminal. L'invention concerne également un dispositif d'affichage de sous-titre. La présente invention améliore la précision et la commodité d'affichage de sous-titre.
