Digital broadcasting system and method of processing data in digital broadcasting system
First Claim
1. A method of processing broadcast data in a broadcast receiver, the method comprising:
- receiving a broadcast signal, the broadcast signal comprising mobile service data, a signaling information table including access information of the mobile service data, fast information channel (FIC) data, and transmission parameter channel (TPC) data, wherein the mobile service data and the signaling information table are encapsulated into at least one of a plurality of RS frames, 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;
demodulating the received broadcast signal;
extracting the signaling information table from the demodulated broadcast signal;
acquiring status information of the mobile service data from the extracted signaling information table; and
identifying a status of the mobile service data using the status information,wherein the broadcast signal further comprises regularly spaced known data sequences, and wherein at least two of the known data sequences are spaced 16 segments apart and have different lengths.

Abstract
A digital broadcasting system and a data processing method are disclosed. The digital broadcast receiving system includes a baseband processor, a management processor, and a presentation processor. The baseband processor receives a broadcast signal including mobile service data and main service data. Herein, the mobile service data configure a Reed-Solomon (RS) frame, and the RS frame includes mobile service data and at least one channel configuration information on the mobile service data. The management processor acquires simple guide information on at least one of a current program and a next program of a corresponding channel from the channel configuration information and stores the acquired simple guide information. The presentation processor receives simple guide information of any one of the current program and the next program, wherein the programs are provided as mobile service through a user-selected channel, from the management processor and displays the received simple guide information on a portion of a display screen of the corresponding channel.
