In a method, an apparatus and a computer program product for service decomposition in IP-broadcast networks, a full service bundle is detected within a first transport stream protocol having a plurality of broadcast packets corresponding to respective broadcast services. The respective service identifiers of the plurality of broadcast packets are evaluated, and the full service bundle is decomposed to create a plurality of decomposed broadcast packets on the basis of the service identifiers. For at least one same service identifier the corresponding plurality of decomposed broadcast packets is sent with the first transport stream protocol as a main service bundle, and for at least one remaining same service identifier the corresponding plurality of decomposed broadcast packets is sent with a second transport stream protocol as a sub service bundle. The second transport stream protocol contains synchronization information of the first transport stream protocol.
