What is LDM (Layer division multiplex)?

Layered-division-multiplexing (LDM) is used to productively convey various administrations with various robustness and throughputs in one TV channel. It is utilized to give an adaptable multi-layer framework transmission through spectrum overlay. In Layer Division Multiplex (LDM) the signal to be communicated comprises various distinctive free signals superimposed together at various injection levels to form a multi-layer signal. Each layer can have its own attributes. LDM framework is fit for conveying robust high-definition (HD) mobile TV and ultra-HDTV administrations in one 6 MHz channel, with a higher spectrum proficiency.
