A method for transmitting a broadcast signal, the method comprising:
- processing broadcast service data based on a delivery protocol, the delivery protocol corresponding to a Real-Time Object Delivery over Unidirectional Transport, ROUTE, protocol or an MPEG Media Transport, MMT, protocol;
- generating low level signaling, LLS, information;
- encapsulating the LLS information and the broadcast service data;
- and
- generating a signal frame by physical layer processing the LLS information and the broadcast service data,
- wherein the LLS information is encapsulated into an IP packet with a well-known address to receivers,
- wherein the LLS information comprises LLS ID information identifying a type of the LLS information, and
- wherein the type of the LLS information further comprises at least one of EA information providing information related to emergency alert and screen clear information providing information related to screen clear to avoid obscuring display image.
An apparatus for transmitting a broadcast signal, the apparatus comprising:
- a signaling generator processing broadcast service data based on a delivery protocol, the delivery protocol corresponding to a Real-Time Object Delivery over Unidirectional Transport, ROUTE, protocol or an MPEG Media Transport, MMT, protocol and generating low level signaling, LLS, information;
- an IP encapsulator encapsulating the LLS information and the broadcast service data;
- and
- a physical layer processor generating a signal frame by physical layer processing the LLS information and the broadcast service data,
- wherein the LLS information is encapsulated into an IP packet with a well-known address to receivers,
- wherein the LLS information comprises LLS ID information identifying a type of the LLS information, and
- wherein the type of the LLS information further comprises at least one of EA information providing information related to emergency alert and screen clear information providing information related to screen clear to avoid obscuring display images.
