- Abstract
- An apparatus and a method for generating a broadcasting signal frame that includes a preamble for signalling injection level information are disclosed. The broadcasting signal frame generating apparatus according to an embodiment of the present invention comprises: an injection level controller for reducing the power of an enhanced layer signal so as to generate a power-reduced enhanced layer signal; a combiner for combining a core layer signal with the power-reduced enhanced layer signal so as to generate a multiplexed signal; a power normaliser for reducing the power of the multiplexed signal to a power corresponding to the core layer signal; a time-interleaver for performing interleaving that is applied to both the core layer signal and the enhanced layer signal so as to generate a time-interleaved signal; and a frame builder for generating a broadcasting signal frame that includes a preamble for signalling injection level information corresponding to the injection level controller.
