1. A method of processing broadcast data in a receiver, the method comprising:
- receiving a broadcast signal including broadcast service data encoded at a code rate, transmission parameters, first signaling information and second signaling information which provide information for acquisition of a service;
demodulating the received broadcast signal;
first decoding the transmission parameters in the demodulated broadcast signal;
second decoding the first-decoded transmission parameters;
block de-interleaving the broadcast service data in the demodulated broadcast signal; and
decoding the block de-interleaved broadcast service data,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, andwherein the transmission parameters include information for identifying the code rate of the broadcast service data.

Abstract
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.

5. A receiver for processing broadcast data, the receiver comprising:
-
a tuner to receive a broadcast signal including broadcast service data encoded at a code rate, transmission parameters, first signaling information and second signaling information which provide information for acquisition of a service; a demodulator to demodulate the received broadcast signal; a first decoder to first decode the transmission parameters in the demodulated broadcast signal; a second decoder to second decode the first-decoded transmission parameters; a de-interleaver to block de-interleave the broadcast service data in the demodulated broadcast signal; and a decoder to decode the block de-interleaved broadcast service data, 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 code rate of the broadcast service data. - View Dependent Claims (6, 7, 8)
