1. A method for transmitting a broadcast signal, the method comprising:
- generating service layer signaling (SLS) information comprising information for discovery and acquisition of broadcast service data;
encoding the broadcast service data and the SLS information based on a delivery protocol;
generating service list table (SLT) information comprising bootstrap information for acquiring the SLS information;
User Datagram Protocol (UDP)/Internet Protocol (IP) encapsulating the broadcast service data, the SLS information, and the SLT information; and
generating a signal frame by physical layer processing the broadcast service data, the SLS information, and the SLT information,wherein the delivery protocol is a Real-Time Object Delivery over Unidirectional Transport (ROUTE) protocol or an MPEG Media Transport (MMT) protocol.
