H.264/AVC　standard　achieved　excellent　encoding　performance　of　at　the　cost　of　increased　computational　complexity　and　falling　encoding　speed.　In　order　to　overcome　poor　real-time　encoding　performance　of　H.264/AVC,　aiming　at　computing　redundancy,　based　on　the　integration　of　visual　selective　attention　mechanism　and　low　complexity　encoding　of　information　analysis　and　visual　perception,　making　use　of　the　distribution　of　motion　vector　and　the　relationship　between　the　mode　decision　probability　and　the　human　visual　attention　a　low-complexity　H.264/AVC　video　coding　scheme　is　implemented　in　this　paper.　The　simulation　results　show　that　the　approach　encoding　effectively　resolves　the　conflict　between　coding　accuracy　and　speed,　saving　about　80%　coding　time　on　average,　which　effectively　maintains　good　video　quality　and　overall　improves　the　encoding　performance　of　H.264/AVC.　©　2011　IEEE.
