1. A broadcast transmitter comprising:
- a Reed-Solomon (RS) frame encoder for generating an RS frame by adding RS parity data and Cyclic Redundancy Check (CRC) data to an RS frame payload, the RS frame payload comprising a plurality of mobile and handheld (M/H) transport packets, each of the plurality of M/H transport packets including an M-byte header, k stuffing bytes, and an (N-M-k)-byte payload, wherein the (N-M-k)-byte payload includes mobile service data, wherein N and M are natural numbers, and k is equal to or greater than 0;
a group formatter for mapping a portion of the RS frame into at least one region of a group that includes a plurality of regions and adding known data sequences, fast information channel (FIC) data and transmission parameter channel (TPC) data to the group, wherein the FIC data contains information for rapid mobile service acquisition, and wherein the TPC data contains FIC version information for identifying an update of the FIC data; and
a modulator for modulating a broadcast signal including the group.

Abstract
A digital broadcasting system and a method of processing data are disclosed, which are robust to error when mobile service data are transmitted. To this end, additional encoding is performed for the mobile service data, whereby it is possible to strongly cope with fast channel change while giving robustness to the mobile service data.

8. A method of processing broadcast data in a broadcast transmitter, the method comprising:
-
generating, by a Reed-Solomon (RS) frame encoder, an RS frame by adding RS parity data and Cyclic Redundancy Check (CRC) data to an RS frame payload, the RS frame payload comprising a plurality of mobile and handheld (M/H) transport packets, each of the plurality of M/H transport packets including an M-byte header, k stuffing bytes, and an (N-M-k)-byte payload, wherein the (N-M-k)-byte payload includes mobile service data, wherein N and M are natural numbers, and k is equal to or greater than 0; mapping, by a group formatter, a portion of the RS frame into at least one region of a group that includes a plurality of regions and adding known data sequences, fast information channel (FIC) data and transmission parameter channel (TPC) data to the group, wherein the FIC data contains information for rapid mobile service acquisition, and wherein the TPC data contains FIC version information for identifying an update of the FIC data; and modulating, by a modulator, a broadcast signal including the group. - View Dependent Claims (9, 10, 11, 12, 13, 14)
