In a broadcast network environment comprising a first broadcast network and a second broadcast network, each broadcast network for broadcasting a plurality of services, each service identifiable by a respective service identity, and in which mobile receivers are assisted to handover reception of a service from one of said first and second broadcast network to the same or a similar service in the other of said first and second broadcast networks, by transmitting handover data toward said mobile receivers, which handover data comprises a mapping between a service identity of a service in said first broadcast network and a corresponding service identity of the same or a similar service in said second broadcast network, a method of generating said handover data for transmission to said mobile receivers,
characterised by the steps of said first broadcast network:
(a) receiving a broadcast signal from said second broadcast network;
(b) for said service identity in said first broadcast network, using a likely common identifier to search for one or more corresponding service in service information data found in said broadcast signal, whereby if available said corresponding service identity of the same or a similar service in said second broadcast network is discovered.
