- Abstract
- A method of generating a broadcast signal frame includes: generating a power-reduced enhancement layer signal by reducing a power of the enhancement layer signal; generating a multiplexed signal by combining the core layer signal and the power-reduced enhancement layer signal; reducing a power of the multiplexed signal to a power level corresponding to a core layer signal to generate a power-reduced multiplexed signal; generating a time-interleaved signal by performing interleaving applied to both the core layer signal and the power-reduced enhancement layer signal in the power-reduced multiplexed signal; and generating a broadcast signal frame, the broadcast signal frame including a preamble for signaling injection level information corresponding to the reduced power enhancement layer signal.
