<p>A method of transmitting a data file over a communication medium (100), comprising determining relative desired reconstruction time frames for different parts of the file, allocating different transmission rates for the different parts of the file responsive to said determining, dividing the file into sections, encoding the sections using a FEC (forward error correction) code having the property that a file section can be reconstructed once a sufficient amount of encoded data relating to that data section is received (104), and transmitting the encoded sections to have effective retransmission rates matching said different retransmission rates (102), such that the parts can be reconstructed in their respective desired time frame.</p> |
