Abstract: A method of transmitting at least one signal over a broadcast network, a broadband network or a hybrid network in a digital transmitter, the method includes generating service layer signaling (SLS) information for at least one service, the at least one 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 service; and transmitting the at least one signal. 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, a MMTP message is delivered by the MMTP session signaled in the SLT, the MMTP message includes a caption asset descriptor, and the caption asset descriptor includes profile information for representing image captions or text captions.
