Abstract: A broadcast signal transmitting method is disclosed. The broadcast signal transmitting method comprises the steps of: processing at least one component of a broadcast service on the basis of a delivery protocol; generating service layer signaling (SLS) information including information on the component; generating service list table (SLT) information including bootstrap information for acquiring the SLS information; and generating a signal frame including a physical layer pipe (PLP) by performing a physical layer processing on the at least one component, the SLS information and the SLT information.
