When　the　new　generation　video　encoding　standard　H.264/AVC　achieved　higher　compression　ratio　and　transmission　robustness,　computational　complexity　was　increased　acutely,　and　was　unfavorable　in　real-time　environmental　application.　Combined　the　visual　perception　characteristics　and　video　encoding　information,　a　new　extraction　method　for　motion　region　of　interest　and　optimized　coding　scheme　were　proposed　in　this　paper.　The　simulation　results　show　that　the　proposed　method　can　obtain　video　motion　region　of　interest　accurately,　and　the　optimized　coding　scheme　can　achieve　reduction　of　53.11%　encoding　time　on　average　with　almost　the　same　quality　and　bit-rate　compared　with　H.264/AVC,　and　can　be　unified　with　other　H.264/AVC　fast　coding　technology　to　enhance　the　encoding　speed　further,　in　order　to　satisfy　the　heterogeneous　networks　and　diversity　terminal　environment.　©　2011　IEEE.
