- Abstract
- An apparatus and method for broadcast signal frame using a boundary between Physical Layer Pipes (PLPs) of a core layer are disclosed. An apparatus for generating broadcast signal frame according to an embodiment of the present invention includes a combiner configured to generate a multiplexed signal by combining a core layer signal and an enhanced layer signal at different power levels; 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 time interleaver information corresponding to the time interleaver, the time interleaver uses one of time interleaver groups, and a boundary between the time interleaver groups is a boundary between Physical Layer Pipes (PLPs) of a core layer corresponding to the core layer signal.
