A method for receiving in a set top box receiver compliant to receive a bundle of transport streams and connected to an IP multicast network, a transport stream from a bundle. The method comprises obtaining a multicast file of stream information (702, 703) multicasted at a service provider offer localisation, processing the stream information to determine a stream localisation (LN 1,1 -LN 1,4 , LN 2,1 - LN 2,3 ) within the IP multicast network, the stream localisation having previously been attributed to the transport stream, obtaining IP packets multicast at the stream localisation, and extracting packetized data from the obtained IP packets, thereby obtaining the transport stream. |
