- In this paper, we present an efficient transmission method of multiple broadcasting services using Layered Division Multiplexing (LDM) and Scalable High Efficiency Video Coding (SHVC) for the next generation terrestrial digital broadcasting such as Advanced Television Systems Committee (ATSC) 3.0. Based on a two-layer LDM technology, each Physical Layer Pipe (PLP) carries each of Base Layer and Enhancement Layer video streams of SHVC, in order to maximize channel utilization when multiple broadcasting services are delivered in a single radio frequency (RF) channel. A performance analysis is conducted when the proposed combination of LDM and SHVC is compared with other combinations such as Time Division Multiplexing (TDM) and/or HEVC simulcast broadcasting. A constant quality measurement is introduced to evaluate the performance of video codec in conjunction with a physical layer system. The proposed combination of LDM and SHVC is implemented in hardware and verified in a real field environment.
