摘要： A digital receiver for processing a broadcast signal includes a receiving module configured to receive the broadcast signal. Further, the broadcast signal includes service components of a broadcast service, service layer signaling (SLS) information for the broadcast service and a service list table for providing bootstrap information, and the service components include at least one of audio or video data. Further, the bootstrap information is different based on a type of delivery protocol of the SLS information, and the type of delivery protocol corresponds to either a Real-time Object delivery over Unidirectional Transport (ROUTE) protocol or a Moving Picture Experts Group (MPEG) Media Transport Protocol (MMTP). The digital receiver also includes a processor configured to process the service list table, the SLS information and the service components of the broadcast service.
