Introduction This manual describes how to use the WebView Livescope Ver. 3.6 Viewer Software. There are two types of viewers, Viewer for Java and the Viewer for PC, and the video sender can use one or the other as required. Both types provide the same basic functions for viewing videos, but differ in terms of other features and functions. The preparations for using the two viewer types and the required operating environment also differ depending on the computer hardware and software used to run the viewer.
WebView Livescope Overview ■ WebView Livescope is the system that allows camera control and live video distribution from a remote location. ■ The system is configured for a camera server and viewer software. The camera server distributes live video taken by the video camera to the Internet or an Intranet. The viewer software can display the video and remotely control the camera.
Viewer Overview There are two types of WebView Livescope Viewer Software: the Viewer for Java and the Viewer for PC. Viewer for Java This is a viewer written using Java. This viewer allows the camera server’s videos to be viewed on any computer with a Web browser that runs Java, regardless of the platform. Because the Java applet is downloaded when the viewer starts up, the first video takes some time to appear.
Viewer for PC This is a viewer that runs as an application. This viewer provides video display and camera control functions and appears in a separate window at startup. While the Viewer for PC has to be pre-installed, it offers the advantage of displaying the first video quickly. At present, only a Windows version of this viewer is available.
Operating Environment For the latest information, please refer to our WebView Product web page: http://www.canon.com/webview Viewer for Java Ver. 3.6 Operating System Windows 2000 (SP4)/ Windows XP (SP1a or SP2) Web Browser Netscape 7.1 or 7.2, or Microsoft Internet Explorer 6.0 (SP1 or SP2) Java VM MSVM Release 5.0.0.3810 (Java VM provided by Microsoft) Java Plug-in 1.4.
Chapter 1 Viewer for Java This chapter describes the preparations required for using the Viewer for Java and explains how to use the viewer.
Preparations for Using the Viewer for Java The Viewer for Java is automatically downloaded from the camera server. There is no need to install it in advance. However, depending on the type of Web browser you are using and your software settings, you must change your Web browser settings. Using Internet Explorer Internet Explorer has a setting that specifies whether the use of Java is permitted. From the “Tools” menu, select “Internet Options” and click the “Advanced” tab.
Using Netscape Netscape also has a setting that specifies whether the use of Java is permitted. Select “Preferences” from the “Edit” menu, click “Advanced” and then click in the “Enable Java” checkbox. * For Netscape 7.1 1 Note Viewer for Java c The settings for the Web browser vary depending on the version used. Refer to the settings given here and check your browser version.
e When You are Connected to a LAN Tip If the camera server is used via an Intranet and you specify the Web browser proxy setting manually, videos are distributed via the proxy. This can result in a slower frame rate and proxy server overload. Use the procedure shown below to set up a “No proxy” connection. Note that if you are accessing a camera server that is located outside a firewall on the internet, registration is not required for the camera server.
Preparations for Using the Viewer for Java ● Use a proxy server for your LAN 1 From the “Tools” menu, select “Internet Options” and click the “Connections” tab. 2 Click “LAN settings” to open the Local Area Network (LAN) Settings dialog box. 3 Tick “Use a proxy server for your LAN” in “Proxy server” and click “Advanced”. 4 In the “Exceptions” field, enter “Camera server IP address: HTTP conversion server service port”. If there are multiple settings, use a semicolon (;) as the separator (e.g. 192.168.100.
Preparations for Using the Viewer for Java ● Manual proxy configuration 1 From the “Edit” menu, select “Preferences”. 2 Select “Proxies” in “Advanced” and select “Manual proxy configuration”. 3 In the “No Proxy for” field, enter “Camera server IP address:HTTP conversion server service port”. If there are multiple settings, use a semicolon (;) as the separator (e.g. 192.168.100.1:80;192.168.0.20:80). 4 Click “OK” to close the Preferences dialog box. * For Netscape 7.
Starting Up the Viewer for Java The Viewer for Java is started up from the Web browser that displayed the Web page for distributing videos. To create a Web page for distributing videos, refer to the user’s manual of the camera server you are using. When the “Using Viewer for Java” button in the Web Browser that displayed the Web page for distributing videos is clicked, the Viewer for Java starts up and connects to the camera server.
Using the Viewer for Java “LiveApplet” Screen There are two types of Viewer for Java (→ p.6). The following is a description of “LiveApplet”. “LiveApplet” is a viewer with a GUI that allows the user to change the camera angle, zoom ratio and backlight adjustment settings. The functions of the GUI displayed on the Web browser are briefly described below.
6 Camera Control Status Window Used to display camera control information (“Camera controllable”, “Camera not controllable”, “Awaiting turn”, “Remaining camera control time”). 7 Start Control Button Used to acquire camera control privileges. 8 Backlight Adjustment Button Compensates for backlighting. Useful when the video appears dark due to backlighting. Click the button again to cancel.
Starting Camera Control Although multiple clients can simultaneously connect to the camera server, multiple clients cannot simultaneously control the camera. Consequently, “control privileges” has been introduced by which only the client who currently holds the control privileges can control the camera. Backlight adjustment and presets can also only be used when you have control privileges. Procedure Click the [Start Control] button to acquire control privileges.
Using the Viewer for Java Controlling the Camera Once you have been granted camera control privileges, you have complete control over the camera angle, the zoom ratio and the backlight adjustment setting.
