Creating Web Pages

62 63

This section describes how to use the Java Viewers to provide video images. Application examples are also given.

This is a LiveApplet sample page which

transmits live pictures from the video

and allows users to control the camera.

This is a sample page which displays live video

at a low frame rate. You can also click to use

LiveApplet to operate the camera at a high rate.

This sample page shows the layout

for four still video images.

This is a sample page for an applet in which the

user specifies the camera control parameters

and a live still video image is displayed.

Viewing Sample Pages

Ready-made video transmission sample pages are provided with the VB101. Follow the procedure below

to view these pages. Refer to these pages when creating your own Web pages.

Launch your Web browser and enter the following URL:

http://

192.168.100.1*/sample/

* The underlined portion is a sample IP address. Enter the actual IP address of the camera server.

Viewing the Pages

The page shown below appears with links to the other sample pages. Click on the link to the

sample page you want to view.

Tip

Using a Java Viewer to Transmit Video Images

When you use a Java Viewer, the viewer applet to be used must be incorporated into the web

page you provide. However, this is not especially difficult. The page can be created using the

HTML normally used to include an applet.

LiveApplet

<applet codebase="http://192.168.100.1*/-wvdoc-01-/LiveApplet/"

code="LiveApplet.class" archive="LiveApplet.zip"

width=450 height=380>

<param name=url value="http://

192.168.100.1*/">

</applet>

Glimpse

<applet codebase="http://192.168.100.1*/-wvdoc-01-/Glimpse/"

code="Glimpse.class" archive="Glimpse.zip"

width=160 height=120>

<param name=url value="http://

192.168.100.1*/">

</applet>

Enter the parameters required by the applet between the <applet> -</applet> tags.

Use the <param> tag for parameters other than the common attributes for applets (codebase,

code, archive, width and height).

Using a Java Viewer to Create a Web page

* The underlined portion is a sample IP address. Enter the actual IP address of camera server.

In Netscape Navigator 3.X, <param> tag values may not be read correctly depending

on the character codes used in the page. If this occurs, the problem can be remedied

by specifying a "ISO-8859-1" as the character set in the <meta> tag at the beginning

of the page in which the applet is running.

Example:

html;charset=ISO-8859-1">

However, if the <meta> tag is used, some characters encoded by the scheme other

than iso-8859-1 will not be displayed correctly. if you want to use foreign languages

in the same page, consider using the frames to construct the page.
