Abstract: A receiving system and a data processing method are disclosed. The receiving system includes a receiving unit, a demodulator, a first handler, and a second handler. The receiving unit receives a broadcast signal including fast information channel (FIC) data, mobile service data, and a service signaling channel, the FIC data including a field indicating that a table signaling service guide bootstrap information to the service signaling channel is included therein, and the mobile service data and the service signaling channel are packetized into an RS frame belonging to a desired ensemble. The demodulator demodulates the received broadcast signal. The first handler acquires service guide bootstrap information from the table included in the service signaling channel. And, the second handler accesses a service guide announcement channel by using the service guide bootstrap information.
