Classification: CPC H | IPC H

Claim 10:
11. 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.
