Abstract

A method and device for transmitting or receiving a broadcast signal are discussed. The method for transmitting the broadcast signal can include processing one or more Internet Protocol (IP) packets into link layer packets, processing the link layer packets to output the broadcast signal, and transmitting the broadcast signal. The one or more IP packets can carry components of a service and service signaling information for signaling the components of the service. The broadcast signal can further include a service list table. The service list table can include one or more of service identification information for identifying the service, capabilities information related to the service, channel number information of the service, category information for indicating a type of the service, protocol information for representing a type of a protocol used to deliver the service signaling information.
