## Abstract

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.

The digital receiver of claim 1, wherein the SLS information further includes a Media Presentation Description (MPD).

### Claim 4

A method of processing a broadcast signal in a digital receiver, the method comprising:
receiving, by a receiving module, the broadcast signal,
wherein 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, wherein 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 used to deliver 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),
wherein the service list table includes protocol information for indicating whether the type of delivery protocol is the ROUTE protocol or the MMTP,
wherein the bootstrap information includes at least one source Internet Protocol (IP) address, at least one destination IP address and at least one destination port of at least one Layered Coding Transport (LCT) channel that delivers the SLS information in response to the protocol information indicating that the type of delivery protocol is the ROUTE protocol, and
wherein the bootstrap information includes at least one destination IP address and at least one destination port of at least one MMTP session that delivers the SLS information and does not include at least one source IP address in response to the protocol information indicating that the type of delivery protocol is the MMTP; and
processing, by a processor, the service list table, the SLS information and the service components of the broadcast service,
wherein the method further comprises:
determining, by the processor, the type of delivery protocol used to deliver the SLS information based on the protocol information,
