With　the　rapid　development　of　electronic　and　computing　technology,　a　growing　number　of　new　applications　in　the　area　of　3D　video　have　come　into　sight,　including　the　popular　interactive　3D　service.　In　this　paper,　the　system　architecture　of　a　user-driven　interactive　3D　video　streaming　transmission　is　presented,　which　is　simple　to　be　realized　with　legacy　displays.　In　particular,　a　novel　idea　is　proposed,　in　which　the　viewer＇s　position　is　determined　using　face　detection　and　tracking　technology,　and　then　the　location　information　is　employed　as　feedback　to　the　video　server-side　in　real　time,　and　at　last　the　server　adaptively　selects　the　best　matched　parts　of　video　stream　data　with　the　user＇s　viewing　angle.　Under　the　existing　network　bandwidth　conditions,　the　proposed　system　enables　the　viewers　to　select　their　viewing　directions　at　their　willing　and　enjoy　a　high　quality　of　3D　experience　anywhere　they　like.　©　2012　GIRI.
