Abstract: An apparatus for transmitting broadcast signal according to the present invention includes an enhanced layer stream partitioner configured to generate first and second enhanced layer partitioned signals by partitioning an enhanced layer stream; first and second combiners configured to generate a first multiplexed signal corresponding to the first enhanced layer partitioned signal and a second multiplexed signal corresponding to the second enhanced layer partitioned signal; first and second power normalizers configured to reduce powers of the first multiplexed signal and the second multiplexed signal; first and second time interleavers configured to generate a first time-interleaved signal corresponding to the first enhanced layer partitioned signal and a second time-interleaved signal corresponding to the second enhanced layer partitioned signal; and first and second OFDM transmitters configured to transmit signals corresponding to the first time-interleaved signal and the second time-interleaved signal using an OFDM communication scheme.
