Abstract
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 in sub-blocks (SB), calculating for each sub-block a respective repair symbol (R1-R9) by 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 transmitting the source symbols of the sub-block, followed by the repair symbol of the sub-block.
Claims14
A data transmission method, comprising the steps of:
- encoding data to be transmitted in the form of source symbols grouped into data blocks,
- assigning each data block a number of repair symbols, and for each block of data:
- distributing the source symbols of the data block into sub-blocks, the number of sub-blocks being equal to the number of repair symbols allocated to the data block,
- assigning a repair symbol to each sub-block of the data block,
- calculating the repair symbol of each sub-block of the data block by a linear combination of source symbols of the sub-block and source symbols of preceding sub-blocks in the data block, and
- transmitting the data block in a stream of data blocks, successively transmitting each sub-block of the data block, each sub-block being transmitted by transmitting the source symbols of the sub-block, followed by the repair symbol of the sub-block.
