Abstract
Disclosed are a device and a method for generating a broadcast signal frame corresponding to a time interleaver for supporting a plurality of operation modes. The device for generating a broadcast signal frame, according to one embodiment of the present invention, comprises: a combiner for generating a multiplexed signal by combining, at different power levels, a core layer signal and an enhancedlayer signal; a power normalizer for lowering power of the multiplexed signal to power corresponding to the core layer signal; a time interleaver for generating a time-interleaved signal by performinginterleaving applied to both the core layer signal and the enhanced layer signal; and a frame builder for generating a broadcast signal frame including a preamble for signaling time interleaver information corresponding to the time interleaver, wherein the time interleaver performs the interleaving in one of a plurality of operation modes.
