1. A method for transmitting a broadcast signal, the method comprising,:

  • generating, by a processor, service data of a broadcast service and service signaling information for signaling the service data, the service data including first service components delivered by using a Movie Picture Everts Group (MPEG) Media Transport Protocol (MMTP) and second service components delivered by using a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol;

    generating, by the processor, a service list table, the service list table including bootstrap information and protocol type information for the broadcast service,wherein protocol type information indicates which one of the MMTP or the ROUTE protocol is used for delivering the service signaling information for the broadcast service, the bootstrap information identifies a transport session carrying the service signaling information for the broadcasts service, and the transport session identified by the bootstrap information has a transport protocol type indicated by the protocol type information;

    generating, by the processor, a broadcast signal including the first and second service components, the service signal information, and the service list table; and

    transmitting, by a broadcasting antenna, the generated broadcast signal through a broadcast network,wherein when the protocol type information indicates that the service signaling information is delivered according to the MMTP, the service signaling information for the broadcast service is carried in an MMTP session identified by the bootstrap information, andwherein the service signaling information carried in the MMTP session includes information used for accessing ROUTE sessions which deliver the second service components of the broadcast service based on the ROUTE protocol.
