1. A Layered Division Multiplexing (LDM)-based broadcast relay apparatus, comprising:
- a memory; and
one or more hardware processors to execute an operation including;
receiving a Layered Division Multiplexed (LDM) broadcast signal including a first layer broadcast signal and a second layer broadcast signal,outputting the first layer broadcast signal based on the received LDM broadcast signal,storing the received LDM broadcast signal in the memory for a delay time,eliminating the output first layer broadcast signal from the stored LDM broadcast signal to output the second layer broadcast signal, andtransmitting the output second layer broadcast signal that results from the eliminating of the output first layer broadcast signal from the stored LDM broadcast signal.

Abstract
Disclosed herein are a Layered Division Multiplexing (LDM)-based broadcast relay apparatus and method. The LDM-based broadcast relay apparatus includes a first layer symbol generation unit for outputting a first layer broadcast signal based on a received Layered Division Multiplexed (LDM) broadcast signal, a data buffer unit for storing the received LDM broadcast signal for a delay time before the first layer broadcast signal is output, and a second layer symbol generation unit for outputting a second layer broadcast signal by eliminating the first layer broadcast signal from the stored broadcast signal.
