1. A method for transmitting a broadcast signal in a transmitter, the method comprising:
- generating service layer signaling (SLS) information, wherein the SLS information provides information for discovery and acquisition of at least one broadcast service and at least one content component of the at least one broadcast service, further the at least one content component comprises an audio component or a video component;
generating low level signaling (LLS) information, the LLS information including identification information for identifying a type of at least one table; and
transmitting the broadcast signal including the SLS information and the LLS information,wherein the identification information included in the LLS information is used to represent a service list table (SLT) among the at least one table, further the SLT is used to enable a receiver to build a basic service list, and bootstrap a discovery of the SLS information for the at least one broadcast service, andwherein the SLT includes SLS protocol information for indicating a type of a delivery protocol of the SLS information and uniform resource locator (URL) information comprising a first URL used for obtaining the SLS information via a broadband other than the delivery protocol,wherein the first URL is used to make an hypertext transfer protocol (HTTP) request for requesting a specific SLS information to a signaling server, andwherein a response message for the HTTP request from the signaling server includes a metadata envelope, and the metadata envelope includes next URL information comprising a second URL for obtaining next scheduled update for the specific SLS information.
