A technique for managing the streaming of digital video content involves providing a unicast stream to a client in response to the play out status of the unicast stream at the client. In particular, a unicast stream is provided to a client based on whether or not the unicast stream is intended for real- time playout at the client. In order to preserve valuable network resources, if the client does not intend the unicast stream for real-time playout, the unicast stream is not provided to the client. Network resources can also be conserved by utilizing one session between a stream server and a client to support more than one active unicast stream between the stream server and the client in the case where at least one of the active unicast streams is not intended for real-time playout at the client.

Technique de gestion de lecture de contenu vidéo numérique, par fourniture de flux unidiffusion au client, selon le statut de lecture de ce flux chez le client. En particulier, un flux unidiffusion est fourni au client selon que ce flux est destiné à la lecture en temps réel ou non. Dans le but de préserver des ressources de réseau précieuses, si le client ne destine pas ledit flux à une lecture en temps réel, on ne lui fournit pas un tel flux. Par ailleurs, il est possible de préserver les ressources de réseau en utilisant une session entre un serveur de flux et un client, pour présenter plusieurs flux unidiffusion actifs entre le serveur et le client, au cas où au moins l'un des flux unidiffusion actifs n'est pas destiné à la lecture en temps réel chez le client.
