Abstract
A method for broadcasting over an IP multicast network an offer of multimedia services received in form of a bundle of transport streams, comprises attributing for each offer (offer 1, offer 2) a determined service provider offer localization (LN0,1, LN0,2) of the IP multicast network, and creating a file of offer information (701) describing for each offer a relation to it attributed service provider offer localization. For each offer transport stream information is extracted from its bundle, the transport stream information comprising a transport stream identification (TS1,1 ? TS1,4, TS2,1 TS2,3) for each transport stream. For each transport stream identification is attributed a determined stream localization (LN1,1 LN1,4, LN2,1 LN2,3) within the IP multicast network. For each offer is created a file of stream information (702, 703) describing for each transport stream a relation to its attributed stream localization.
