Project Code: 14MR9100, Development of Service and Transmission Technology for Convergent Realistic Broadcast, Namho Hur

Abstract: An apparatus and method for broadcast signal frame using layered division multiplexing 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 shared by the core layer signal and the enhanced layer signal, using the time-interleaved signal.

KSP Keywords: Broadcasting system, Information shared, Next generation broadcasting systems, Power Levels, Time Interleaver, division multiplexing, layered division multiplexing, time-interleaved
