Abstract

La présente invention concerne des procédés et des systèmes (Fig. 8) assurant des services numériques complets tels que vidéo à la demande, diffusion numérique ainsi qu'un décodeur universel (600) capable d'assurer ces divers services numériques. Cette transmission est rendue possible par une pluralité d'architectures de matériel et par des méthodes complémentaires de transmission de données permettant d'identifier ces services distincts via un guide électronique des programmes. Le décodeur universel (600) selon la présente invention est en mesure de distinguer entre les différents services à partir d'informations reçues du guide électronique des programme et comporte une architecture matérielle spécifique avec mémoire de grande capacité. La présente invention concerne également des options d'écoute telles que multi-diffusion et caractéristiques de programmation VCR virtuelles avec fonctions pause, enregistrement et plans figés, sans la volatilité et la mauvaise qualité d'une diffusion en continu sur Internet. Par ailleurs, ces divers services numériques sont dispensés via une liaison de communication unidirectionnelle.
