Abstract
Equipment and method for generating a broadcast signal frame by using layered division multiplexing are disclosed. The equipment for generating a broadcast signal frame, according to one embodiment ofthe present invention, comprises: a combiner for combining a core layer signal and an enhanced layer signal of differing power levels so as to generate a multiplexed signal; a power normalizer for lowering the power 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 to be 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 start position information of physical layer pipes (PLPs) and time interleaver information shared between the core layer signal and the enhanced layer signal.
