Fountain codes have been suggested as an efficient solution for multimedia communications over erasure packet network. Therefore, the unequal error protection (UEP) fountain codes schemes are needed for the multimedia data of different importance. This paper proposed a novel technique to optimize the degree distribution of the generalized fountain codes that can provide strong UEP property. We further verify our work with simulations. Simulation results show that the proposed fountain codes have a better decoding performance than the fountain codes without optimization.
