In this paper the forward error correction (FEC) codes useful for multimedia wireless
transmissions are discussed. The class of usable codes are produced by multiple
description (packet equivalence during transmission) after an initial hierarchical
representation stage (joint source channel coding). The Mojette transform is used to perform
the implementation. A fair comparison with other optimal codes (systematic or not) is
provided. JPEG2000 images transmission under a wireless link shows possible strategies.
