APPARATUS FOR TRANSMITTING BROADCAST SIGNALS, APPARATUS FOR RECEIVING BROADCAST SIGNALS, METHOD OF TRANSMITTING BROADCAST SIGNALS AND METHOD OF RECEIVING BROADCAST SIGNALS

摘要

The present invention proposes a method of transmitting a broadcast signal. The method of transmitting the broadcast signal according to the present invention proposes a system capable of supporting a next-generation broadcast service in an environment that supports next-generation broadcasting using a terrestrial broadcast network and an Internet protocol network. In addition, the present invention proposes an efficient signaling scheme for both the terrestrial broadcasting network and the Internet protocol network in the environment that supports next-generation broadcasting.

1. A method of providing a broadcast service at a PD (Primary Device), the method comprising:
receiving broadcast signals; processing the broadcast signals to output a SLT (Service List Table) and ROUTE (Real-Time Object Delivery over Unidirectional Transport) packets; parsing the SLT including bootstrap information, the bootstrap information indicating a transport session carrying SLS (Service Layer Signaling), wherein the SLS signals service data of the broadcast service, and the service data includes streaming components of the broadcast service and app components; obtaining the SLS by accessing the transport session carrying the SLS; and obtaining the streaming components and the app components by using the SLS, wherein the app components include data related to an app-based enhancement of the broadcast service, and wherein the app components are NRT (Non-Real Time) components.
