摘要
A method for transmitting data over a wireless network to a plurality of receivers connected to the wireless network is provided consisting of applying a superposition coded multicast or broadcast so as to create a multi-resolution multicast or broadcast signal to transmit data to the plurality of receivers as a scalable multicast or broadcast. The method consists of separating the data into one or more quality layers; converting the data in each quality layer into individual protected layer data streams by applying a protection or robustness means; modulating each said protected layer data stream using a modulation means, the modulations means for each said protected layer data stream not necessarily being the same; superimposing the modulated data of all layers into a single broadcasting or multicasting transmission block; and transmitting the single broadcasting or multicasting transmission block to the plurality of receivers linked to the wireless network.
