Control information on a data broadcasting application for each delivery segment is distributed.An application service descriptor for each delivery segment is arranged into an MP table stored in a PA message on the side of a broadcast station. Each application service descriptor indicates information on one application type and priority of the application type. A receiver further selects a specific MH-AIT and data transmission message, on the basis of the priority for each application type, indicated with the application service descriptor, and a default AIT flag.
