Web Pages for Video Distribution Features of the Java Viewers These viewers are supplied as Java applets. They run on Web browsers that are Java-capable, such as the Netscape Navigator and Microsoft Internet Explorer browsers. The applets are downloaded from the camera server to the Web browser and are then run by the Web browser. The features of the Java Viewers are described below. Video distribution and camera operation using the WebView-HTTP protocol. Penetrate firewalls to access external sites. Because they are automatically downloaded, the Java Viewers do not need to be pre-installed by the client. Java Viewers run on a wide variety of platforms . e Because the Java applets are downloaded using the HTTP protocol when the Tip Viewer starts up, the start up time is longer than the Helper Viewer. 5 Java Viewer Types Creating Web Pages Two Java Viewers are "LiveApplet", which has video display and camera control functions, and "Glimpse", which only has video display functions. Because both viewers use WebView-HTTP as the transfer protocol, they do not require special settings to penetrate firewalls. IViewer Types Viewer Name LiveApplet Glimpse Functions Displays videos from the VB101. Allows camera control. Allows overlays and superimposition of bitmaps in the video frame. * Because video is not displayed until the viewer has finished downloading, video display takes longer than with the Helper Viewer. Allows the video distribution interval to be set. * Downloading is faster than "LiveApplet" because it has only simple functions and size is small. 93
