Embedded　video　surveillance　has　become　a　large　market　as　the　number　of　installed　cameras　around　us　can　show.　At　the　same　time,　video　compression　technique　has　been　rapidly　developed　in　recent　years.　As　a　new　generation　of　video　coding　compression　standard,　extensive　attention　has　been　given　to　H.264/AVC.　On　the　other　hand,　because　of　good　cost-effective　and　low-power　consumption,　DSP　is　widely　used　in　the　fields　of　embedded　system　and　multimedia　processing.　There　are　needs　for　embedded　video　surveillance　that　can　make　use　of　the　video　compression　technique　in　more　efficiency　security　systems.　In　this　paper,　a　scheme　of　design　and　implementation　about　video　surveillance　system　based　on　H.264/AVC　is　designed　and　described　It　is　built　on　ADSP-BF561,　with　a　wide　range　of　peripheral　interface,　to　achieve　several　functions,　such　as　video　compression,　data　stream　control,　network　transmission,　PTZ　and　so　on.　The　experimental　results　indicate　that　the　stability　and　other　expected　features　of　system,　including　Real-time　surveillance　video　encoding,　can　be　ensured.
