BROADCASTING SIGNAL FRAME GENERATION APPARATUS AND METHOD USING LAYERED DIVISIONAL MULTIPLEXING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18450004 titled 'BROADCASTING SIGNAL FRAME GENERATION APPARATUS AND METHOD USING LAYERED DIVISIONAL MULTIPLEXING
Simplified Explanation
The patent application describes an apparatus and method for broadcasting signals using layered division multiplexing.
- The apparatus includes a combiner that combines a core layer signal and an enhanced layer signal at different power levels.
- A power normalizer reduces the power of the combined signal to match the power level of the core layer signal.
- A time interleaver performs interleaving on both the core layer signal and the enhanced layer signal to generate a time-interleaved signal.
- A frame builder generates a broadcast signal frame that includes a preamble for signaling time interleaver information shared by the core layer signal and the enhanced layer signal, using the time-interleaved signal.
Original Abstract Submitted
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.
