Abstract
A method and device are provided for the transmission of data. After organizing the data into words all having the same number of bits, tables are formed each comprising a plurality of words, the words of these tables are coded by means of an error correcting code, and the bits of each table are transmitted using an interleaving method, at a transmission rate sufficient so that, during the time of formation of the table of rank N, a number R of tables, of rank N, N-1, N-2, . . . , N-R are transmitted. The reverse operations are carried out at reception. This method makes it possible to tolerate interruptions in transmission having a relatively long duration, without introducing too great a delay between the source and the user circuit.
