Request concerning disclosure of live videos
With respect to the disclosure of live videos, we request that sufficient consideration be given to
matters of privacy and rights not to be photographed. Canon considers the following points concerning
such matters when it operates camera sites for which it has been responsible to install and operate:
-We take measures such as adding limitations on zoom magnifications so that people cannot
make special specifications.
-When videos are taken of specific buildings, interiors and the like, we install the camera only after
receiving approval from the administrator.
Please note that the operator of the camera site and not Canon has full responsibility regarding the
disclosure of live videos.

If you are interested in having your Website linked from our WebView World Website,
please contact us from one of the following options (Be sure to read “Request
Concerning the Disclosure of Live Pictures” in the Introduction page):

2. Read “2. Links from WebView World” in the CD-ROM’s ReadMe-E.txt and e-mail us
with the required information.
*Note that the link may be refused in some cases.
Web Pages for Video Distribution
To distribute live video using the VB150, you create a dedicated web page. The viewers that can be used
with the VB150 are “Viewer for Java” (with or without camera control function) and “Viewer for PC”, and
detailed parameters can be specified for each of these. You need to determine which of these viewers is
supported and create the Web page.
c
Note
●File Names
The VB150 can handle file names consisting of up to 8 characters followed
by a 3-character extension. Note that the names of applets built into the
VB150 are exceptions to this rule.
●The VB150 includes a built-in Web server. If the content of Web pages used
for distributing video is stored onto a the flash memory, the VB150 can be
used alone for distributing Web pages and videos over the Web. Refer to
step 3 on page 113 for information on saving content.
The above page is built into the VB150 and can be accessed from the URL below.
http://192.168.100.1*/
*The underlined portion is a sample IP address. Enter the actual IP address set for the VB150 (→VB150
User’s Manual P.38).
e
Tip
You can use the Language setting function for the Browser to create a multi-
lingual Web site. For example, if you set the French-language top page as
index-fr.htm and the English-language top page as index.htm and supply
users with a URL address terminates in slash, such as http://vb150/sample/,
the server will transmit a file that corresponds with the language setting for
the Browser. For further information on the Language setting function for the
Browser, refer to the Browser Help.

Viewer for Java
The Viewer for Java provides two types of viewers: LiveApplet containing video display and
camera control functions, and Glimpse containing a video display function. Because both viewers
use the WebView-HTTP transfer protocol, data can pass through firewalls with no need for special
settings.
Viewer Overview
There are two types of viewers: the Viewer for Java and the Viewer for PC.

Viewing Sample Pages
Ready-made video distribution sample pages are provided with the VB150. 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 set for the VB150 (→
VB150 User’s Manual P.38).

Guide to Creating Web Pages for Video Distribution
This section describes how to use the Viewer for Java to provide videos. Application examples are also given.
Using the Viewer for Java to Distribute Videos
When you use the Viewer for Java, 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/">
<param name=cabbase value="LiveApplet.cab">
</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/">
<param name=cabbase value="Glimpse.cab">
</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).
Creating a Web Page that Uses the Viewer for Java
* The underlined portion is a sample IP address. Enter the actual IP address set for the VB150.

● Writing IP Addresses
Using the Web server functions built into the VB150, IP addresses can be
expressed as <_I_P_A_D_D_R_> (all upper-case characters, including the angle
brackets) in the two file types (htm,wvh) used by the Web server in the VB150.
Since <_I_P_A_D_D_R> is replaced with the actual IP address when accessed,
the Web page does not need to be changed even when the IP address for the
VB150 is changed. In addition, NAT can be supported by specifying a Web page
global address. (→P.22, VB150 User’s Manual P.57)

Using Glimpse and LiveApplet Together
This section describes how to create a Web page that allows clients to use Glimpse to download
quickly and display live video at a low frame rate, and then use LiveApplet to view video at a high
frame rate and control the camera when they find videos they are particularly interested in.
