Claim 14:
15. A method of transmitting a signal in a digital transmitter, the method comprising:
transmitting the signal including a service list table (SLT) and at least one service component which is carried by a Real-time Object delivery over Unidirectional Transport (ROUTE) session or a MPEG media transport protocol (MMTP) session,
wherein the ROUTE session includes Layered Coding Transport (LCT) channels, further each of the LCT channels is identified based on Transport Session Identifier (TSI) information,
wherein a LCT channel carries Service-based Transport Session Instance Description (S-TSID) information,
wherein the SLT provides at least one bootstrap information that allows a digital receiver to discover at least one Service Layer Signaling (SLS) information for each service,
wherein for ROUTE-delivered services, first bootstrap information includes a source IP address, a destination IP address and a destination port of at least one LCT channel carrying first SLS information,
wherein for MMTP-delivered services, second bootstrap information includes a destination IP address and a destination port of the MMTP session carrying second SLS information,
further the second bootstrap information does not include a source IP address.
