OPTIMIZED METHOD OF TRANSMITTING LAYERED CONTENTS TO MOBILE TERMINALS AND VIA A RADIO INFRASTRUCTURE WITH ACCESS PROCEDURE OF TDM/TDMA/OFDMA TYPE, AND ASSOCIATED PROCESSING DEVICE

摘要

A method is dedicated to the transmission, via a transmission infrastructure (RC), using waves and with an access procedure relying on at least time division multiplexing, of contents of at least one channel, each of which is arranged in a base data layer and at least one layer of improvement data associated respectively with different transmission timeslots, and which are sliced into portions transmitted during the timeslots respectively associated with their layers. This method comprises i) the insertion at a chosen location of each portion to be transmitted of a base data layer, at the level of a chosen network layer, of at least one learning sequence processed according to a configuration scheme identical to that used to process said improvement data layer, and ii) on receipt of a portion of a base data layer of a content in a terminal (TC), the extraction of the learning sequence inserted at the level of a chosen network layer, then the estimation of the quality of reception on the basis of this extracted learning sequence, and the authorization to use the portion of the improvement data layer of the content when the estimated quality is greater than a chosen threshold.
