- Abstract
- An apparatus and method for generating a broadcast signal frame using layered division multiplexing are disclosed. An apparatus for generating a broadcast signal frame according to an embodiment of the present invention comprises: a combiner for generating a multiplexed signal by combining a core layer signal and an enhanced layer signal at different power levels; a power normalizer for lowering the power of the multiplexed signal to power corresponding to the core layer signal; a time interleaver for generating a time-interleaved signal by performing interleaving which is applied to both thecore layer signal and the enhanced layer signal; and a frame builder for generating a broadcast signal frame including a bootstrap and a preamble using the time-interleaved signal.
