<p>The method involves transmitting data encoded according to an initial coding type to receiving terminals (32, 33). Compatibility of respective capacities of the terminals with the type is controlled by a server (30). Data coding is adapted in accordance with capacity of one terminal before data transmission, by the server, so that the terminal can decode the data, if there is incompatibility between the type and the capacity.
