关于swfobject.embedSWF的问题

各位我这儿这些代码是什么意思：
<script language="javascript" type="text/javascript">
        $(document).ready(function(){
            swfobject.embedSWF("flash/top.swf", "mainGallery", "695", "298", "9.0.0", "", {}, { menu: "false", scaleMode: "noScale", bgcolor: "#EEEEEE" , base : "." });
            swfobject.embedSWF("flash/right.swf", "subGallery", "458", "256", "9.0.0", "", {}, { menu: "false", scaleMode: "noScale", bgcolor: "#EEEEEE" , base : "." });
            swfobject.embedSWF("flash/player.swf", "videoPlayer", "458", "256", "9.0.0", "", {imgUrl: "video.jpg", flvUrl: "video.flv"}, { menu: "false", scaleMode: "noScale", bgcolor: "#EEEEEE" , base : "." });
        });
    </script>
