Digital broadcasting system and data processing method
First Claim
1. A method of processing broadcast data in a broadcast transmitter, the method comprising:
- performing, by a Reed Solomon (RS) encoder, RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data in order to generate an RS frame belonging to an ensemble, the ensemble including signaling information data describing rating information of the mobile service data;
mapping data of the RS frame into a plurality of groups, wherein each of the plurality of groups includes a portion of data included in the RS frame, a plurality of known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the FIC data includes information for rapid mobile service acquisition, and wherein the TPC data includes FIC version information for indicating an update of the FIC data; and
transmitting a broadcast signal including the plurality of groups,wherein the FIC data and the TPC data are positioned between a first known data sequence and a second known data sequence among the plurality of known data sequences with each group.

Abstract
A digital broadcasting system and method of processing data therein are disclosed. A receiving system of the digital broadcasting system includes a baseband processor unit receiving a broadcast signal including mobile service data and main service data, the mobile service data configuring an RS frame, the RS frame including the mobile service data and at least one signaling information data describing rating information of the mobile service data, a management processor unit obtaining the rating information of the mobile service data by parsing the signaling information data from the RS frame, the management processor unit determining a presence or non-presence of a viewing restriction by comparing the obtained rating information of the mobile service data to viewing restriction rating information set by a user, and a presentation processor unit blocking the mobile service data if the viewing restriction of the mobile service data is determined.
