Claim:
1. A method for transmitting a broadcast signal, the method comprising: encoding Data Pipe (DP) data corresponding to a Data Pipe (DP) carrying at least one broadcast service or at least one service component; mapping the encoded DP data to constellations; Multiple Input Multiple Output (MIMO) encoding the mapped DP data; time-interleaving the MIMO encoded DP data; generating at least one signal frame including the time-interleaved DP data; inserting MIMO pilots into the generated at least one signal frame according to at least one pilot pattern, wherein the MIMO pilots are encoded according to one of two MIMO pilot encoding algorithms, a Hadamard encoding algorithm and a Null encoding algorithm; orthogonal frequency division multiplexing (OFDM) modulating the generated at least one signal frame; and transmitting at least one broadcast signal including the modulated at least one signal frame.
