- An apparatus and method for generating a broadcast signal frame including preamble for signaling injection level information. An apparatus for generating broadcast signal frame according to an embodiment of the present invention includes an injection level controller configured to generate a power reduced enhanced layer signal by reducing a power of an enhanced layer signal; a combiner configured to generate a multiplexed signal by combining a core layer signal and the power reduced enhanced layer signal; a power normalizer configured to reduce the power of the multiplexed signal to a power level corresponding to the core layer signal; a time interleaver configured to generate a time-interleaved signal by performing interleaving that is applied to both the core layer signal and the enhanced layer signal; and a frame builder configured to generate a broadcast signal frame including a preamble for signaling injection level information corresponding to the injection level controller.
