- In this paper, we present framing and multiple-physical layer pipe (PLP) structures for layered division multiplexing (LDM)-based next generation terrestrial broadcasting systems. As a framing structure, single-layer frames and multi-layer frames can be simultaneously transmitted by a time division multiplexing (TDM) approach. In addition to a conventional multiple-PLP strategy, which is basically time-divisioned, layer-divisioned multiple-PLP strategies are introduced in order to implement low complexity and high efficiency LDM systems. In the case that the cells of upper layer and lower layer are super-imposed, a practical consideration of lower layer cell indication is addressed. Performance analysis is given when multiple PLPs are serviced with different TDM and LDM configurations.
