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.

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.
■ Example of a Web page for video distribution (VB150’s built-in page)
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.36).
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 111 for information on saving content.
e
Tip
You can use the Language setting function for the Browser to create a multilingual 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 Overview
There are two types of viewers: the Viewer for Java and the Viewer for PC.
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.

Using the Viewer for Java to Distribute Videos
This section describes how to use the Viewer for Java to provide videos. Application examples are also given.
Creating a Web Page that Uses the Viewer for Java
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/"
Guide to Creating Web Pages for Video Distribution
code="LiveApplet.class" archive="LiveApplet.zip"
width=450 height=380>

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).
* 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.55)

If the MIME setting is not specified correctly for the Web server, you may not
be able to launch the Viewer for PC. Be sure to specify the setting correctly.
Creating wvh files
This section describes how to create the wvh file required for launching the Viewer for PC application.
Use a text editor or similar program to create a new text file and type the following type of
1
code in the file:
(Example)
192.168.100.1 65310
192.168.100.1 65311
wvhttp:192.168.100.1 80
● The first line gives the IP address (or host name) of the VB150 and the TCP port
Guide to Creating Web Pages for Video Distribution
number used for the video transmission service.
The default setting is 65310 (→VB150 User's Manual P.54). The default setting will be
used if no particular value is specified.
● The second line gives the IP address (or host name) of the VB150 and the TCP port
number used for the camera control. The default setting is 65311 (→VB150 User's
Manual P.54). The default setting will be used if no particular value is specified.
● The third line gives the setting for the Viewer for PC to use HTTP protocol. After
"wvhttp:", type in the IP address of the VB150 and "80" as the HTTP port number. As a
result of this, you will be able to view video images from the VB150 through firewalls.
* Type in the actual IP address (or host name) set for the VB150 .
After you save the text file and quit the text editor program, create a wvh file by changing
2
the file name and extension. Be sure to add the ".wvh" extension, as in "WebView.wvh".
File names can contain up to 8 characters. (eg. WebView)
e
Tip
Viewer for PC supports WebView Livescope protocol and HTTP protocol.
● WebView Livescope protocol: Cannot be viewed through firewalls. This
protocol is primarily for clients who are connected directly to the Internet.
● HTTP protocol: In general, this protocol is used with Web browsers. By
using this protocol, clients inside firewalls can view videos by penetrating
firewalls. The Viewer for Java also uses this protocol.

Using the Viewer for PC to Distribute Videos
Example of a Web Page that Uses the Viewer for PC
This section describes an sample Web page in which the Viewer for PC is used.
1
Click the link to launch the
viewer.
Include the tags that link to the wvh file in the text or images in the Web page.
1
<A HREF="WebView.wvh">Let's view the image</A>
e
Tip
22
19
To use the sample page template in the VB150 to supply videos,
specify <A HREF=http://IP address of the VB150/sample/helper/default.wvh>.
Distributing Videos Using a Browser Only
You can also use the WebView-HTTP protocol to provide videos from the camera directly to a Web
browser. Some example of this are described in this section.
Displaying the Live Video
at Access as a Still Picture
When a client accesses the Web page that provides videos, the video shot at that point can be
supplied as a still picture.

<IMG SRC=http://192.168.100.1/-wvhttp-01-/GetStillImage>
(or)
<IMG SRC=http://192.168.100.1/-wvhttp-01-/GetOneShot>
* The underlined portion is a sample IP adderess. Enter the actual IP address set for the VB150.
Displaying a Specified Number Of Live Video
Frames As a Video at Access
The Server Push format provided as an extended function by Netscape Communications Corp.
can be used to distribute multiple-frame images. However, these images can only be displayed on
Netscape Navigator. In the coding example below, 100 frames of live video are distributed when
the client accesses the server.
<IMG SRC=http://192.168.100.1/-wvhttp-01-/GetOneShot?frame_count=100>
* The underlined portion is a sample IP adderess. Enter the actual IP address set for the VB150.
e
Tip
● frame_count=no_limit
This setting removes the limits on the number of image frames.
● Be sure to specify the camera if the Video Input (→ VB150 User’s Manual
P.40) setting on the VB150 is set to Multiple.

Distributing Videos Using a Browser Only
Displaying Live Video from a Specified Angle
as Still Pictures
By specifying the camera angle as a parameter in the HTML code beforehand, you can display
the picture from a specified camera angle. The example below displays a still picture shot with the
camera panned right by 40° and tilted down 10°.
<IMG SRC=http://192.168.100.1/-wvhttp-01-/GetStillImage?p=40&t=-10>
* The underscored portion is a sample IP address. Enter the actual IP address set for the VB150.
■GetStillImage Parameters
Description
Parameter
p/pan
c
Note
24
21
Specifies the camera pan angle. "p" is a 1°unit, and "pan" is a 0.01°unit. For
example if the camera pans right 20°, then p is 20 and pan is 2000. If this
parameter is omitted, the camera pan angle is not controlled.
t/tilt
Specifies the camera tilt angle. "t" is a 1°unit, and "tilt" is a 0.01°unit. If this
parameter is omitted, the camera tilt angle is not controlled.
z/zoom
Specifies camera zoom. "z" is ten times the zoom ratio of the widest angle,
and "zoom" is the view angle in 0.01°units (horizontal direction. If this
parameter is omitted, camera zoom is not controlled.
b/back_light
Specifies camera backlight compensation. When this parameter is set to on, the picture
captured will be bright and when this parameter is set to off, the picture captured will be
dark. If this parameter is omitted, camera backlight compensation is not controlled.
camera_id
Assigns the numbers 1 to 4 to camera 1 to 4. If this parameter is omitted, the
camera that is currently selected will be used.
delay
Waiting time until camera focus is stabilized (in milliseconds). Specified in the
range 0 to 10000.
option
Specifies how errors are dealt with. When "skip_on_error" is specified, the
process will be continued. When "quit_on_error" is specified, the process will
be aborted. The following errors can occur: failure to acquire camera control
right, loss of camera control, camera selection errors and camera control
errors. To omit, the default value is "quit_on_error".
seq
Allows any number (sequence number) to be specified to avoid displaying old
still pictures (numeric value).
v/image_size
Specifies the display size of the picture. Settings of 640 x 240, 320 x 240, and
160 x 120 are possible. Styles for v and image_size are different: For v, only
the horizontal size is specified, as in "v=640", for instance; while for
image_size, both horizontal and vertical sizes are specified, as in
"image_size=320x240", for instance.
q/quality
Specifies picture quality. Use an integer between 1 and 99. If omitted, the
value set in the VB150 is used.
If old still pictures are displayed, you can prevent this recurring by specifying
a sequence number in the "seq" parameter.
Example of video distribution using one global address
One fixed global address is required if the VB150 is being used to distribute live video on the Internet. An
Internet service provider (ISP) that offers a single-address fixed global address service can be used (Note:
a router with NAT function is required).
Example:
In this example, we use the global address
192.168.1.10 assigned by the ISP. We also set the
private address 192.168.100.2 in the VB150 (and
192.168.100.1 for the router).

A sample page of the VB150 is automatically generated based on the IP address that was actually
assigned (192.168.100.2 in this case). In this case, this page cannot be viewed in the Viewer for
Java or the Viewer for PC when “http://192.168.1.10/sample/” is accessed through the Internet.
Set "Global Address for Web Pages" (→ VB150 User's Manual P.55) to 192.168.1.10. If you are
not using the VB150's Web server, describe the Web pages for distributing videos as follows.
Set the Viewer for Java description (→ P.6) as follows:
