Title
(EN) METHOD AND SYSTEM FOR AUDIO-VISUAL LIVE CONTENT DELIVERY
(FR) PROCÉDÉ ET SYSTÈME DE DISTRIBUTION DE CONTENU EN DIRECT AUDIOVISUEL
Abstract
(EN)
An audio-visual live content delivery system includes: a client (110) having access to a provider network (102) via a gateway (140); an audio-visual live content delivering equipment (120) comprising a multicaster for transmitting audio-visual live contents in multicast form via the provider network (102); a de-multicaster (150) being able to perform a conversion in unicast form of audio-visual live contents received in multicast form from the multicaster; and a controller (130) managing routing of requests to get audio-visual live contents. The client (110) performs a discovery procedure aiming at receiving information on potential presence and availability of the de- multicaster (150). When the client (110) intends receiving a targeted audio-visual live content, the client (110) sends to the controller (130) a request providing indication of presence and availability, or not, of the de-multicaster (150). Then the controller (130) decides how redirecting the client (110) to fulfill the request, according at least to the indication of presence and availability, or not, of the de-multicaster (150).

L'invention concerne un système de distribution de contenu en direct audiovisuel qui comprend : un client (110) ayant accès à un réseau de fournisseur (102) par l'intermédiaire d'une passerelle (140) ; un équipement de distribution de contenu en direct audiovisuel (120) comprenant une station de multidiffusion pour transmettre des contenus en direct audiovisuels sous une forme de multidiffusion par l'intermédiaire du réseau de fournisseur (102) ; un station de dé-multidiffusion (150) pouvant effectuer une conversion sous forme de monodiffusion de contenus en direct audiovisuels reçus sous forme de multidiffusion à partir de la station de multidiffusion ; et un dispositif de commande (130) gérant le routage des demandes pour obtenir des contenus en direct audiovisuels. Le client (110) effectue une procédure de découverte visant à recevoir des informations relatives à la présence et à la disponibilité potentielles de la station de dé-multidiffusion (150). Lorsque le client (110) a l'intention de recevoir un contenu en direct audiovisuel ciblé, le client (110) envoie au dispositif de commande (130) une demande fournissant une indication de présence et de disponibilité, ou non, de la station de dé-multidiffusion (150). Ensuite, le dispositif de commande (130) décide comment rediriger le client (110) afin de satisfaire la demande, selon au moins de l'indication de la présence et de la disponibilité, ou non, de la station de dé-multidiffusion (150).
