Abstract:
1. A method for transmitting, via a wave-based transmission infrastructure using an access method relying on multiplexing that is at least time division multiplexing of content from at least one channel, each piece of content being arranged into one base data layer and at least one enhancement data layer, respectively associated with different transmission time slices, and broken down into portions transmitted during the time slices respectively associated with their layers, the method comprising: inserting, in a chosen location of each portion of a base data layer to be transmitted, within a chosen network layer, at least one learning sequence processed according to a configuration scheme identical to that used to process the enhancement data layer, wherein the formation of each learning sequence, the locations chosen for inserting the learning sequence, and the network layer within which the insertion is carried out, are indicated through a signaling message and extracting, upon receipt of a base data layer portion of a piece of content, the learning sequence inserted into a chosen network layer, then estimating the reception quality based on that extracted learning sequence, and allowing it to use the next portion of the enhancement data layer of the content whenever the estimated quality is above a chosen threshold.
