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 localisation (LN<SUB>0,1</SUB>, LN<SUB>0,2</SUB>) 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 localisation. For each offer transport stream information is extracted from its bundle, the transport stream information comprising a transport stream identification (TS<img id="custom-character-00001" he="3.13mm" wi="1.44mm" file="US20060156362A1-20060713-P00900.TIF" alt="custom character" img-content="character" img-format="tif"/>1,1 ? TS<SUB>1,4</SUB>, TS<SUB>2,1 </SUB>TS<SUB>2,3</SUB>) for each transport stream. For each transport stream identification is attributed a determined stream localisation (LN<SUB>1,1 </SUB>LN<SUB>1,4</SUB>, LN<SUB>2,1 </SUB>LN<SUB>2,3</SUB>) 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 localisation.
