Abstract
An apparatus and a method for generating a broadcast signal frame using layered division multiplexing are disclosed. The broadcast signal frame generation apparatus according to one embodiment of thepresent 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 thepower of the multiplexed signal to a power corresponding to the core layer signal; a time-interleaver for generating a time-interleaved signal by performing interleaving which is applied to the corelayer signal and the enhanced layer signal together; and a frame builder for generating a broadcast signal frame including size information of physical layer pipes (PLPs) and a preamble for signalingtime-interleaver information which is shared with the core layer signal and the enhanced layer signal.
