DIGITAL BROADCAST SYSTEM FOR TRANSMITTING/RECEIVING DIGITAL BROADCAST DATA, AND DATA PROCESSING METHOD FOR USE IN THE SAME

摘要

The present invention is directed to a digital broadcast system and a data processing method. A broadcast signal in which mobile service data and main service data are multiplexed is transmitted and received. Then, in a broadcasting receiver, the program table information including information about a service or a program of an ensemble is parsed according to an identifier of the ensemble in which the mobile service data are multiplexed, in the received broadcast signal. And a mobile service is outputted by using the mobile service data and the parsed program table information.

1. A method of processing broadcast data in a transmitter, the method comprising:
encoding broadcast service data for a service at a first code rate; block interleaving the encoded broadcast service data; convolutional interleaving the block-interleaved broadcast service data; first encoding transmission parameters to add parity data to the transmission parameters; second encoding the first-encoded transmission parameters at a second code rate; and transmitting a frame that includes the convolutional interleaved broadcast service data and the second-encoded transmission parameters, wherein the frame further includes first signaling information and second signaling information which provide information for acquisition of the service, wherein the first signaling information includes information for identifying a broadcast stream within which the broadcast service data are carried, service type information for indicating a type of the service, and information for indicating whether or not the service is hidden, wherein the second signaling information includes Internet Protocol (IP) address information for accessing of the broadcast service data, and wherein the transmission parameters include information for identifying the first code rate and information related to the frame.
