Patent

CA 2506782

A resident application and a second application are provided in a set-top terminal (158-L) to receive a TV broadcast service and network personal video recorder (NPVR) service, respectively. The resident application is suspended in favor of the second application when a user changes from a broadcast channel to a NPVR enabled channel, and vice versa. In an embodiment where a digital video recorder (DVR) set-top terminal (158-L) is used, a DVR server therein provides trick mode functions (pause, rewind and fast-forward) before an NPVR session, e.g., a Look Back session, is established. In another embodiment, during an NPVR session the DVR server plays back recorded programming content downloaded from a communications network (140), and provides trick mode functions as well.

L'invention concerne la fourniture d'une application résidente et d'une seconde application dans un terminal décodeur, aux fins de réception d'un service de diffusion TV et d'un service de magnétoscope personnel sur réseau (NPVR) respectivement. L'application résidente est suspendue en faveur de la seconde application quand un utilisateur passe d'un canal de diffusion à un canal à activation NPVR et vice versa. Dans un mode de réalisation dans lequel un terminal décodeur de magnétoscope numérique (DVR) est utilisé, un serveur DVR confère des fonctions en mode d'enrichissement (pause, retour en arrière et avance rapide) avant l'établissement d'une session NPVR, par exemple, une session de retour en arrière. Dans un autre mode de réalisation, pendant une session NPVR, le serveur DVR lit un contenu de programmation enregistré et téléchargé à partir d'un réseau de communications et confère également des fonctions en mode d'enrichissement.
