Abstract

L'invention concerne un système et un procédé d'enregistrement vidéo numérique (DVR) qui rend inutiles les tampons vidéo circulaires antérieurs et résout les problèmes connexes par l'utilisation des informations provenant d'un service de guides de programmes pour spécifier le tampon de longueur appropriée. Ainsi, les anciennes parties d'un programme ne sont pas effacées pour cause de limitation de la capacité de la mémoire tampon, et les ressources du système ne sont pas inefficacement attribuées aux petits programmes. L'invention est particulièrement compatible avec la lecture et l'enregistrement intégrant des fonctions de pause et de rediffusion instantanée. Selon le choix de l'utilisateur, tout programme en cours de lecture ou d'enregistrement peut être stocké dans une mémoire à long terme.
