Abstract

A transmitting/receiving system and a data processing method of the same are disclosed herein. The receiving system may include a receiving unit, a first processing unit, and a second processing unit. The receiving unit receives a broadcast signal including mobile service data from at least one slot. The first processing unit acquires FIC segments divided from an FIC chunk of at least one sub-frame. Herein, each FIC segment comprises a 2-byte segment header and a 35-byte segment payload. The segment header includes an FIC type information, a number of a corresponding FIC segment, and a number of a last FIC segment among the FIC segments divided from the FIC chunk. The second processing unit obtains the FIC chunk including signaling information between at least one ensemble and at least one mobile service from respective payloads of the FIC segments, based upon the acquired FIC type information, number of the corresponding FIC segment, and number of the last FIC segment of each FIC segment.
