Transmitting/receiving system and method of processing data in the transmitting/receiving system
First Claim
1. A method of processing data in a broadcast transmitter, the method comprising:
- encoding broadcast service data for a broadcast service in order to generate a Reed-Solomon (RS) frame belonging to an ensemble;
encoding transmission parameter channel (TPC) data;
encoding fast information channel (FIC) data; and
transmitting a first frame including data in the generated RS frame, the encoded TPC data and the encoded FIC data,wherein the first frame comprises a plurality of second frames,wherein the TPC data include information for at least one of the plurality of second frames,wherein the FIC data comprise an FIC chunk that includes an FIC chunk header and an FIC chunk payload,wherein the FIC chunk payload includes an ensemble identifier for identifying the ensemble, at least one ensemble loop and at least one service loop,wherein the FIC chunk header comprises first length information, second length information and third length information,wherein the first length information indicates a length of at least one extension field added to the FIC chunk header,wherein the second length information indicates a length of at least one extension field added to the at least one ensemble loop, andwherein the third length information indicates a length of at least one extension field added to the at least one service loop.

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.
