Broadcast signal tranmission device, broadcast signal reception device, broadcast signal tranmission method, and broadcast signal reception method

A receiving system for processing a broadcast signal, the receiving system comprising:

• a tuner configured to receive the broadcast signal including signal frames, the signal frames including service data for a service that is carried by one or more Real-Time Object Delivery over Unidirectional Transport (ROUTE) sessions, low level signaling information for fast channel scans and service acquisition of one or more services including the service, and physical layer signaling information including information for identifying whether the low level signaling information is included in a current signal frame, wherein the low level signaling information includes first service identification information for identifying the service, service category information for the service and capability information for the service;
• a demodulator configured to demodulate data of the signal frames;
• an error correction decoder configured to decode the physical layer signaling information, the low level signaling information, and the service data in the demodulated data;
• and
• a processor configured to provide the service to a user by processing the service data based on the physical layer signaling information and the low level signaling information.

A transmitting system for a broadcast signal, the transmitting system comprising:

• a first forward error correction (FEC) encoder configured to encode service data for a service that is carried by one or more Real-Time Object Delivery over Unidirectional Transport (ROUTE) sessions;
• a second FEC encoder configured to encode low level signaling information for fast channel scans and service acquisition of one or more services including the service;
• a Low Density Parity Check (LDPC) encoder configured to encode physical layer signaling information including information for identifying whether the low level signaling information is included in a current signal frame, wherein the low level signaling information includes first service identification information for identifying the service, service category information for the service and capability information for the service;
• a modulator configured to modulate data of signal frames that include the encoded service data, the encoded low level signaling information and the encoded physical layer signaling information;
• and
• a transmitter configured to transmit the broadcast signal including the modulated data.

A method of processing a broadcast signal in a receiving system, the method comprising:

• receiving, by a tuner, the broadcast signal including signal frames, the signal frames including service data for a service that is carried by one or more Real-Time Object Delivery over Unidirectional Transport (ROUTE) sessions, low level signaling information for fast channel scans and service acquisition of one or more services including the service, and physical layer signaling information including information for identifying whether the low level signaling information is included in a current signal frame, wherein the low level signaling information includes first service identification information for identifying the service, service category information for the service and capability information for the service;
• demodulating, by a demodulator, data of the signal frames;
• decoding, by an error correction decoder, the physical layer signaling information in the demodulated data;
• decoding, by the error correction decoder, the low level signaling information in the demodulated data;
• decoding, by the error correction decoder, the service data in the demodulated data;
• and
• providing, by a processor, the service to a user by processing the service data based on the physical layer signaling information and the low level signaling information.
