## Abstract

A method for transmitting a broadcast signal in a digital transmitter, includes generating, by a processor, service data of a broadcast service and service signaling information for signaling the service data, the service data including first service components delivered on a Moving Picture Experts Group (MPEG) Media Transport Protocol (MMTP) session or second service components delivered on a Real-Time Object Delivery over Unidirectional Transport (ROUTE) session; generating, by the processor, a service list table including bootstrap information and protocol information for a type of delivery protocol of the service signaling information, wherein the protocol information for the type of delivery protocol of the service signaling information relates to the MMTP or the ROUTE; generating, by the processor, a broadcast signal including the service signaling information, the service list table, and the first or second service components; and transmitting, by a broadcasting antenna, the generated broadcast signal.
