Abrégé
(EN)
A networked personal video recording ('PVR') system (310) couples a plurality of clients (350) to one or more PVR media servers (330) over a network (340). One or more PVR media servers (330) include television tuners (924) to tune television signals. A storage medium buffers (230) the television signals to implement PVR functionality. For example, the PVR media server(330) records television programs for clients. Clients are assigned to television tuners (924), and the clients display television programs received at the assigned tuner. The network(340) transfers the buffered television signals to the clients.

Un magnétoscope numérique en réseau ( PVR ) relie une pluralité de clients à un ou plusieurs serveurs de supports PVR au sein d'un réseau. Un ou plusieurs serveurs de supports PVR comprennent des syntoniseurs de télévision pour les signaux de télévision. Un support de stockage met les signaux de télévision en mémoire tampon pour la mise en oeuvre de la fonctionnalité PVR. Par exemple, le serveur de supports PVR enregistre des programmes d télévision pour des clients. Ces clients se voient attribués des syntoniseurs de téléviseur et affichent les programmes de télévision reçus sur le syntoniseur qui leur ont été attribué. Le réseau transfert les signaux de télévision tamponnés aux clients.
