Apparatus for error correction coding a data stream of information in blocks of information coded by error correction, a process to perform the coding for error correction.A recording, and apparatus for blocks of error correction information encoded for error correction in a data stream of serial information
APPROPRIATE FOR COLLECTION OF ERROSS BY CODING A FLOW OF INFORMATION DATA IN BLOCKS OF INFORMATION CODED BY CORRECTION OF ERROS ES, PROCESS TO CONDUCT CODING BY ERROR CORRECTION, GRAVATION PORTER, AND, APPROPRIATE FOR CORRECTION BLOCKS OF ERROR INFORMATION CODED BY ERROR CORRECTION IN A FLUX OF SERIOUS INFORMATION DATA"A device is presented to encode, with correction of errors, a flow of information in blocks of information coded by error correction,comprising an input terminal (20) for reception of the information stream. An error correction coding unit (22) is present to perform an error correction encoding step on parts of the information stream in order to obtain the blocks of information coded by correction of error, a block of information coded by error correction comprising a plurality of n sync blocks, each block sync comprising a word sync and a part of the information coded by error correction,where n is a positive integer greater than 3. An output terminal (24) is present to provide blocks of information coded by error correction. According to the invention, the error correction coding unit (22) is adapted to provide one of mutually different sync words to each of the sync blocks in the information block coded by error correction, in such a way that the sequence of two sync words from two subsequent sync blocks in the information block coded by error correction is unique for each subsequent two sync blocks in the information block coded by error correction,m being a whole number for which it applies 2 m n.
