Abstract:
1. A method of processing a digital broadcast signal, the method comprising: encoding, at a digital broadcast signal transmitter, signaling data for signaling of mobile service data; forming, at the digital broadcast signal transmitter, data groups, wherein forming the data groups comprises mapping the mobile service data into corresponding locations of the data groups, adding known data sequences and at least one segmented known data sequence to the data groups, and adding the signaling data between a (K)th known data sequence and (K+1)th known data sequence of the known data sequences, wherein the data groups include a first data group, a second data group and a third data group; transmitting, at the digital broadcast signal transmitter, the digital broadcast signal including the data groups, wherein the first data group is a preceding adjacent data group to the second data group and the third data group is a succeeding adjacent data group to the second data group in time order in the digital broadcast signal; and wherein the signaling data includes at least first information indicating whether a segmented known data sequence of the second data group is concatenated to a segmented known data sequence of the first data group to form a known data sequence, or second information indicating whether a segmented known data sequence of the second data group is concatenated to a segmented known data sequence of the third data group to form a known data sequence.
