Abstract: A method of transmitting at least one broadcast signal in a digital transmitter is discussed. The method includes generating service layer signaling (SLS) information for at least one broadcast service, the at least one broadcast service consisting of at least one continuous video component, at least one continuous audio component and at least one closed caption component; generating a service list table (SLT) for providing bootstrap information that allows a receiver to discover the SLS information for the at least one broadcast service. Further, the bootstrap information includes a destination IP address and a destination port of a MPEG media transport protocol (MMTP) session carrying MMTP-specific SLS; and transmitting the at least one broadcast signal.
