A new unequal error protection scheme based on FMO

In this paper we present a slice group based unequal error protection (UEP) scheme for video transmission over error- prone networks. We propose a method to assign macroblock to slice groups based on a variation of H.264/AVC dispersed FMO mode and k-means clustering algorithm. In addition, a Converged Motion Estimation (CME) is proposed to further improve our UEP scheme. The idea behind the CME is to make the macroblocks be referenced in a skewed manner, such that highly important macroblocks are converged on only a few and the use of redundancy for error protection is efficient. Our experiments on many video sequences show promising results.
