Abstract: A method of receiving broadcast signals is provided. The method includes receiving the broadcast signals and decoding a service layer table including bootstrap information from the received broadcast signals. The bootstrap information indicates an MPEG Media Transport Protocol (MMTP) session carrying service layer signaling. The method further includes decoding the service layer signaling from MPEG Media Transport (MMT) packets based on the MMTP and decoding a transport session description from a Real-Time Object Delivery over Unidirectional Transport (ROUTE) session. In addition, service components are delivered by the MMT packets based on MPEG Media Transport Protocol, and non-real time components are delivered by Layered Coding Transport (LCT) packets in the ROUTE session. The service components delivered in the MMT packets and the non-real time components delivered in the LCT packets are decoded, respectively.
