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:
- forming data groups, wherein each of the data groups is composed of data blocks and includes a portion of mobile service data in a Reed-Solomon (RS) frame, signaling data and known data sequences, wherein a third data block of the data blocks includes a first known data sequence of the known data sequences, wherein a fourth data block of the data blocks includes a second known data sequence and a third known data sequence of the known data sequences and the signaling data, wherein a fifth data block of the data blocks includes a fourth known data sequence of the known data sequences, wherein a sixth data block of the data blocks includes a fifth known data sequence of the known data sequences, and wherein a seventh data block of the data blocks includes a sixth known data sequence of the known data sequences; and
transmitting a transmission frame including data of the data groups, the transmission frame being composed of a plurality of sub-frames,wherein the RS frame belonging to an ensemble is built by performing RS-CRC (Cyclic Redundancy Check) encoding on the mobile service data, the ensemble comprising a service map table (SMT) that includes access information of the mobile service data,wherein the signaling data include transmission parameter channel (TPC) data that include information for indicating a current sub-frame number within the transmission frame, andwherein the SMT further includes profile information, audio sampling rate information and language information for the mobile service data.

Abstract
A digital broadcasting system and a method for controlling the same are disclosed. A method for controlling a digital broadcast receiving system includes the steps of receiving a broadcast signal having mobile service data and main service data multiplexed therein, extracting transmission parameter channel (TPC) signaling information and fast information channel (FIC) signaling information from a data group within the received mobile service data, by using the extracted fast information channel (FIC) signaling information, acquiring a program table describing virtual channel information and service of an ensemble, the ensemble being a virtual channel group of the received mobile service data, by using the acquired program table, detecting a descriptor defining basic information required for accessing the received service, and, by using the detected descriptor, controlling the receiving system to enable access to the corresponding service.
