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.
Claims12
A Layered Division Multiplexing (LDM)-based broadcast relay apparatus, comprising:
- one or more hardware processor to implement:
- a first layer symbol generation unit for outputting a first layer broadcast signal based on a Layered Division Multiplexed (LDM) broadcast signal received;
- a data buffer unit for storing the received LDM broadcast signal for a delay time before the outputting of 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 LDM broadcast signal.
A Layered Division Multiplexing (LDM)-based broadcast relay method using an LDM-based broadcast relay apparatus, comprising:
- outputting a first layer broadcast signal on a received Layered Division Multiplexed (LDM) broadcast signal received;
- storing the received LDM broadcast signal for a delay time before the outputting of the first layer broadcast signal;
- and
- outputting a second layer broadcast signal by eliminating the first layer broadcast signal from the stored LDM broadcast signal.
