Abstract
IP data is multicast from one or more servers () in sessions through a network (N) comprising a plurality of routers (R) in a multicast tree to transmission sites (S) of a DVB-T network, where the data is encapsulated by IPEsand transmitted uni-directionally to mobile user equipment (UE). A controller () builds up a schedule of session data concerning sessions transmitted by the servers () and instructs the IPEs to send join messages to receive data for selected sessions. The join messages may include the address of the source and may be transmitted in good time before the start of the session.
