Classification: CPC H | IPC H

Claim 15:
16. 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.
