Digital broadcasting system and method of processing data in digital broadcasting system
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 a mobile service and on a signaling information table including access information of the mobile service to form an RS frame;
dividing 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, regularly spaced 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, wherein the TPC data includes FIC version information for indicating an update of the FIC data, and wherein at least two of the known data sequences are spaced 16 segments apart; and
transmitting a broadcast signal including the plurality of groups,wherein the signaling information table further includes basic information about the mobile service, the basic information including start time information, duration information, and title information of the mobile service.

Abstract
A digital broadcast receiver and a control method thereof are disclosed. The control method of the digital broadcast receiver includes receiving a broadcast signal into which mobile service data and main service data are multiplexed, extracting transmission parameter channel (TPC) signaling information and fast information channel (FIC) signaling information from a data group in the received mobile service data, acquiring a program table describing virtual channel information and a service of an ensemble, which is a virtual channel group of the received mobile service data, using the extracted FIC signaling information, selectively detecting a first message descriptor mapped with time information or a second message descriptor not mapped with time information, using the acquired program table, performing a control operation to display a message defined in the detected message descriptor.
