BROADCAST SIGNAL FRAME GENERATION DEVICE AND BROADCAST SIGNAL FRAME GENERATION METHOD USING BOUNDARY OF PHYSICAL LAYER PIPES OF CORE LAYER

摘要

Disclosed are a broadcast signal frame generation device and method using a boundary of physical layer pipes of a core layer. The broadcast signal frame generation device 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 enhanced layer signal; 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 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 time interleaver information corresponding to the time interleaver, wherein 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.
