Abstract
A system for the transmission of digital data elements corresponding to at least one application each comprising at least one stream of data elements, the data elements being constituted by digital elements distributed in the time-frequency space and transmitted in the form of symbols constituted by a multiplex of orthogonal carrier frequencies modulated by a set of the digital elements and broadcast simultaneously, the symbols being organized in successive frames, each frame being organized in at least one data conveying channel, each channel being constituted by a succession of at least one consecutive symbol. The data elements may advantageously be transmitted, in each channel, either in transparent mode or in packet mode.
