A method for delivering a targeted audio-visual live content to a client, the method being performed by an audio-visual live content delivery system including: - the client located in a local area network interconnected to a provider network by a gateway providing access to the provider network or located in the gateway providing access to the provider network; - an audio-visual live content delivering equipment comprising one or more servers among which a multicaster for transmitting audio-visual live contents in multicast form via the provider network; - a de-multicaster in the gateway providing access to the provider network or in any device located in the local area network, the de-multicaster being able to perform a conversion in unicast form of audio-visual live contents received in multicast form from the multicaster; - a controller managing routing of requests to get audio-visual live contents; characterized in that the method comprises: - the client performs a discovery procedure (200; 210; 500; 510; 701; 901; 911; 1111) aiming at receiving, from the gateway providing access to the provider network and from any device connected to the local area network, information on potential presence and availability of the de-multicaster; and when the client intends receiving the targeted audio-visual live content: - the client sends to the controller a request (201; 211; 503; 513; 704; 904; 914; 1114) to get the targeted audio-visual live content which provides indication of presence and availability, or not, of the de-multicaster; - the controller decides how redirecting the client to fulfill the request to get the targeted audio-visual live content, according at least to the indication of presence and availability, or not, of the de-multicaster. - the client located in a local area network interconnected to a provider network by a gateway providing access to the provider network or located in the gateway providing access to the provider network; - an audio-visual live content delivering equipment comprising one or more servers among which a multicaster for transmitting audio-visual live contents in multicast form via the provider network; - a de-multicaster in the gateway providing access to the provider network or in any device located in the local area network, the de-multicaster being able to perform a conversion in unicast form of audio-visual live contents received in multicast form from the multicaster; - a controller managing routing of requests to get audio-visual live contents; characterized in that the method comprises: - the client performs a discovery procedure (200; 210; 500; 510; 701; 901; 911; 1111) aiming at receiving, from the gateway providing access to the provider network and from any device connected to the local area network, information on potential presence and availability of the de-multicaster; - the client performs a discovery procedure (200; 210; 500; 510; 701; 901; 911; 1111) aiming at receiving, from the gateway providing access to the provider network and from any device connected to the local area network, information on potential presence and availability of the de-multicaster; and when the client intends receiving the targeted audio-visual live content: - the client sends to the controller a request (201; 211; 503; 513; 704; 904; 914; 1114) to get the targeted audio-visual live content which provides indication of presence and availability, or not, of the de-multicaster; - the controller decides how redirecting the client to fulfill the request to get the targeted audio-visual live content, according at least to the indication of presence and availability, or not, of the de-multicaster. - the client sends to the controller a request (201; 211; 503; 513; 704; 904; 914; 1114) to get the targeted audio-visual live content which provides indication of presence and availability, or not, of the de-multicaster; - the controller decides how redirecting the client to fulfill the request to get the targeted audio-visual live content, according at least to the indication of presence and availability, or not, of the de-multicaster.
