The invention relates to a method for transmitting data, comprising the steps of: encoding data to be transmitted in the form of source symbols (S) grouped into a data block (DB), distributing the source symbols of the data block among sub-blocks (SB), calculating for each sub-block a respective repair symbol (R1-R9) by means of a linear combination of source symbols of the sub-block, and transmitting the data block in a stream of data blocks, by successively transmitting each sub-block of the data block, each sub-block being transmitted by transmission of the source symbols of the sub-block,followed by the repair symbol of the sub-block.
