Abstract:
The invention concerns a method for broadcasting a plurality of multimedia programmes generated by operators of different services, whereby one or more network headends broadcast (in 102) on a reference multicast address a list associating identifiers of service operators with at least one first level service multicast address, the reference multicast address being previously known to all the terminals capable of receiving and multiplexing broadcast multiplexed contents and said reference multicast address being different from all the broadcasting multicast addresses.
