1. A method for transmitting a broadcast signal, the method comprising:
- generating service layer signaling (SLS) information for broadcast service data of a broadcast service, wherein the SLS information provides information for discover and acquisition of the broadcast service and content component of the broadcast service, and the SLS information processed by a delivery protocol, the delivery protocol being Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or MPEG Media Transport Protocol (MMT) protocol;
generating low level signaling (LLS) information, the LLS information including table ID information identifying a type of signaling information included in the LLS information; and
transmitting the broadcast signal including the broadcast service data, the SLS information and the LLS information,wherein the type of the signaling information includes service list table (SLT) information including information used for discovering the SLS information and building a basic service list, andwherein the SLT information includes SLS protocol information indicating a type of the delivery protocol of the SLS information as the ROUTE protocol or the MMT protocol and uniform resource locator (URL) information comprising a base URL used for obtaining the SLS information for the broadcast service via a broadband other than the delivery protocol,wherein the base URL is used to make an hypertext transfer protocol (HTTP) request for requesting a specific SLS signaling information to a signaling server, andwherein a response message for the HTTP request from the signaling server includes a metadata envelope including the specific SLS information, and the metadata envelop further includes next URL information comprising a URL for obtaining next scheduled update for the specific SLS information.
