Overview
WebView Livescope is a system for transmitting to a computer live images taken by a video
camera (Canon VC-C4/VC-C4R/VC-C3/VC-C1 MK-II) installed in a remote location, via the
Internet/Intranets.
The image recipient (hereafter called the "client") can easily view the image with a Web
browser. Moreover, since the operator can easily control the camera from a remote Web
browser via a network, images of a highly on-site feel can be transmitted in real-time.
Introduction
Images from the WebView Livescope server are displayed on a special viewer. This viewer
can be embedded into a Web page, enabling the creation of appealing Web pages and
greatly expanding the possibilities of the Internet/Intranets, such as monitoring from remote
locations using a Web browser, to achieve networks that are more useful for business.
Because WebView Livescope uses the HTTP protocol in addition to its own conventional
protocol, it is now possible, as long as an environment for viewing external Web pages exists,
to view images from external WebView Livescope camera servers even from within corporate
LANs where firewalls have been erected.
WebView Livescope is an image transmission system that enables users to
actively (by performing operations by oneself) view live (showing now) video
from homepages by allowing users to change camera angle and zoom magnification.

the user's purposes.
5
Features
■ Easy transmission of live images to the Internet or an Intranet
Uses HTTP protocol in addition to the unique (WebView-TCP) transmission protocol. Image data
can be sent through a firewall without changing network administration settings.
■ Transmission and reception of high-resolution video
WebView Livescope uses the Motion-JPEG image compression system and supports the Osprey100 capture board from ViewCast.com and the Meteor, Meteor II and Meteor/PPB capture boards
from Matrox.
■ Detailed camera control
When the Canon VC-C4 Communication Camera is used, the user can control
the camera angles (pan and tilt) and zoom ratio just as if he or she were actually
behind the camera. It is also possible to set restrictions limiting the camera
angles and zoom ratios that can be used.
■ Four cameras controlled by the same server
WebView Livescope supports up to 4 cameras concurrently.
This gives better image quality and a wider field of view.
■ Communication camera is freely controllable by users receiving live
images.
You can easily control pan/tilt angles, zoom magnification and backlight compensation features of
a remotely installed camera from your computer screen via a network. Camera position can also
be input in advance by using the [Preset] feature. The client can move the camera into the desired
position instantly just by selecting a registered preset.
■ Concurrent video reception by up to 100 users
One server can be used to view video by up to 100 users at a time. The number of concurrent
accesses is set on the camera server to suit the bandwidth of the network being used.
■ Control privileges to prevent contention for camera control
The introduction of control privileges means that contention between multiple clients concurrently
trying to control the camera can be avoided. The default period for which a client has exclusive
control of the camera is 20 seconds. (This can be changed at the server.)
6
■ Support for multiple concurrent image sizes
You can select any of 4 image sizes (640×480, 320×240, 160×120 and 80×60) and transmit them
simultaneously.
■ Enhanced security functions
Video distribution destinations can be restricted using IP addresses.
Introduction
■ Automatic sample page generation function
This function automatically modifies the contents of the sample web page files based on the
camera server settings. The sender can create web pages based on these sample pages. The
wvh files used to start up the helper viewer from the web browser can also be generated
automatically and sent.
■ Panorama image generation function
Version 3.1 of the software features a new function that automatically controls the camera as it
shoots multiple images and then integrates and stores those images as a single panorama image.
The camera angle and zoom ratios in a stored panorama image can be controlled from the viewer
for realistically direct operation. This function also improves the user interface since the panorama
image can be used by the administrator to set the field of view or specify preset positions.
■ Firewall penetration
The helper viewer provides a firewall penetration function previously available only on Java
viewers. This enables video images to be sent regardless of the user's software environment.
■ Automatic shooting, recording and uploading of still images at set intervals
Version 3.1 provides a still image collection function that collects still images shot by the camera
at regular intervals, uploads the collected images to an FTP server and automatically transmits
the images from the web server. Still images shot by the camera according to a preset schedule
can be saved to a local disk on the camera server or uploaded to a specified FTP server.
■ Access log analysis for a quick and clear snapshot of system usage
In version 3.1, the collected access log data is analyzed and the access status displayed as a
graph or table to give a clear and accurate picture of system usage for each user. This picture
shows information such as the number of accesses per day, the periods of heavy usage and the
access time for each individual, and can also be accessed remotely.
7
System Configuration
The web server and camera server are connected to the viewer using IP (Internet Protocol).
Normally, the live video is distributed via the internet, but ordinary public phone lines or ISDN lines
can also be used for a direct connection.

Information Sending Side
Web Server
The web server is the computer that runs the web server software. When
accessed from a web browser, this server sends HTML data to the browser.
WebView Livescope Camera Server
This server is made up of a camera and a computer that
is equipped with an image capture board and runs the
VC-C4
COMMUNI
f:4-64mmCATION CAMERA
1:1.4-2.8
camera server software. Normally, the server modules
start up automatically when the computer is switched on.
■ Server Module Types and Functions
Module
10
Functions
Camera control
server
This server receives camera control protocol signals from clients such as the
helper viewer and HTTP conversion server and performs camera control
functions such as pan and tilt. The camera control protocol used is the
WebView-TCP camera control protocol.
Video capture server
This server performs JPEG compression on video signals received from the
camera (VC-C4/VC-C4R/VC-C3/VC-C1 MK-II) via the capture board (Osprey100, Meteor or Meteor-II/PPB) and sends the compressed signals to a client such
as a helper viewer or HTTP conversion server. The protocol used is the dedicated
WebView-TCP video transmission protocol.
HTTP server
This server converts the dedicated WebView-TCP video transmission and
WebView-TCP camera control protocols to the HTTP 1.0-based WebViewHTTP protocol. This module can also operate as a simple web server.
Upload server
This server provides a still image collection function that periodically collects
video data according to a specified schedule and either saves the collected
images to a local disk or uses the FTP protocol to upload the images to a web
server machine connected to the network.
Maintenance server
This server receives communications from the WebView Livescope manager
and modifies settings on the camera server or restarts related services. This
server program can be used to manage the camera server from a remote
location. The communications protocol used is the dedicated WebView-TCP
remote maintenance protocol.
System Configuration
WebView Livescope Manager
The WebView Livescope Manager allows the camera server to be managed
from a remote location.
■ Application Types and Functions
Application
Function
The WebView Livescope manager allows each of the camera server modules to
be managed remotely. This application also starts up the administrative viewer
(see below) and the web browser used for access log analysis.
Administrative viewer
This is a helper viewer for the administrator which allows camera control
operations that can only be performed by the camera server administrator and
allows interactive specification of camera presets and restrictions on the field of
view. The administrative viewer can be started up when the WebView
Livescope manager is connected to the camera server. The administrative
viewer also allows the administrator to control the camera during operations
when camera control by ordinary users is forbidden.
Access log analysis
tool
This consists of a CGI program and HTML that analyzes the server access
logs collected on the camera server and then visually presents the viewer
access statistics for the camera server to the administrator. Under the default
settings, HTML pages are downloaded to the client (web browser) by the HTTP
conversion server and the CGI program is also launched by the HTTP
conversion server.
Introduction
WebView Livescope
manager
Information Receiving Side
WebView Livescope Viewer
Viewer software is used to view video images sent from the camera
server on a web browser. The two types of viewer software are
described in the table below.
■ Viewer Software Types and Functions
Viewer Software
a
IMPORTANT
Function
Java viewer
The Java viewer allows images from the Camera Server to be viewed on a web browser that
is capable of running Java applets.
Because the Java viewer is downloaded automatically, it does not need to be installed
beforehand like the helper viewer, and it is compatible with any platform capable of running
Java applications.
Where firewalls are installed, this viewer penetrates the firewalls unconditionally since it uses
the HTTP protocol. However, operation may be unstable with some platforms or web browser
types.
Also, because the viewer is downloaded when the web site loads, it starts up and runs more
slowly than the helper viewer.
Helper viewer
This is a helper application launched from a web browser and used to view video images sent
from the camera server.
The helper viewer must be installed beforehand.
Because it does not need to be downloaded. the helper viewer launches more quickly than the
Java viewer. If a viewer will be used frequently, use the helper viewer rather than the Java viewer.
Where firewalls are installed, this viewer penetrates the firewalls unconditionally since it uses the
HTTP protocol.

Caution
Before you begin the installation
If there is web server software already installed on the PC to be used for installation,
you must avoid conflicting the port number of WebView Livescope HTTP server and
web server. To ensure that the WebView Livescope HTTP server can penetrate
firewalls, it is installed with a default port number of 80. To ensure that the web
server and HTTP server do not both use port number 80, you should change the web
server port number to a number such as 8080. A precondition of this is that you use
the WWW server function (see P.53).
Starting the Installer

Notes on Using the Software
This section provides some points to note and items to refer to when you are using WebView
Livescope camera server software.
Connection distance between the camera server and the
camera (VC-C4/VC-C4R/VC-C3/VC-C1 MK-II)
Use a cable no longer than 15 meters, as stipulated in the RS-232C standard. Successful
operation cannot be guaranteed if a cable longer than 15 meters is used. (When using cascade
connections, a cable no longer than 15 meters should be used to connect each camera. Refer
to P.18 for information on cascade connections.)
When a WWW server is running on the same computer as the
camera server
Use the WWW server function.
* For more information on using a proxy web server, refer to "Setting the Web Server Functions"
on P.53.
For subjects not suited to auto focusing, such as night scenes
or objects with no light-dark contrast, set the camera to "Far
Fixed".
* For more information on the auto focus settings, see "Changing the Camera Settings" on P.38.
If the camera server is connected to the internet or an intranet,
1 fixed IP address is always required.
* Dynamic IP addresses using DHCP cannot be assigned.

Chapter 2
Camera Server Setting
This chapter describes how to specify the settings for the WebView Livescope
camera server and how to manage the server and monitor its status.
Camera Server Setting
The camera server settings can be specified either on the computer on which the camera server
software was installed (local maintenance) or by from a computer connected to the network (remote
maintenance).
Using the Remote Maintenance Function to Set Up the Camera Server
The WebView Livescope manager can be used to change the camera server settings from a
remote computer connected to the camera server via a network.
● To use the remote maintenance function to set up the camera server, the WebView
Livescope manager program must be installed on the computer connected to the network
(see P.20).
● The computer on which the manager program is installed must be running Windows 95,
Windows 98, Windows NT 4.0 or Windows 2000 with IE 4.0 or later installed (see P.12).
● To use the remote maintenance function, the camera server must first be set up to allow
remote maintenance.*
● Remote maintenance cannot be conducted across a firewall.
* For information on how to set up the camera server, see "Setting the Remote Maintenance
Usage Conditions" on P.33.

Administrator's Privileges
The administrative viewer has the following special privileges not available
to ordinary viewers:
● The administrative viewer has unlimited video connection time. After
completing the setup, you should quit the manager viewer.
● When the administrative viewer acquires camera control privileges, it
forcibly retains continued camera control even when a request for camera
control privileges is received from an ordinary user. After completing
camera server setup, you must quit the administrative viewer.
Alternatively, you can click the control privileges button in the
administrative viewer again to relinquish control privileges.
● When a view restrictions has been set on the camera server, the
administrative viewer can control the camera beyond the specified field of
view. However, during setup, note that ordinary viewers can also view the
areas outside the specified field of view.

camera movement is
automatically restricted.
Camera Server Setting
● The limits on the angles of pan and tilt are imposed not by the
camera's range of movement, but by the angle of the field of view.
Consequently, the camera's range of movement narrows when the
wide-angle limits in the zoom ratio (angle of view) adjustment are set
wide.
When wide-angle is selected,
the field of view will be
exceeded if the camera's
range of movement remains
unchanged. Accordingly, the
range of movement is
automatically reduced.

Chapter 4
Creating Web Pages
This chapter describes how to use WebView Livescope to transmit
information. Video can be transmitted in a number of ways, including
displaying video or still images on a web page and displaying multiple images.
The Sender's Web Page
The sender with the camera server installed builds a web page to be used for video image
transmission. To view the video images, the client must use a viewer provided by the sender. The
two viewers that can be used are "Java viewers" and the "helper viewer". The sender decides in
advance which viewer will be supported and builds a dedicated web page for the viewer. Be sure that
you fully understand the features of each type of viewer before you design your web page.

video images.

Features of Java Viewers
These are viewers supplied as Java applets and can be run by any web browser that runs
Java, including the current mainstream browsers, Netscape Navigator and Microsoft Internet
Explorer. The applets are downloaded from the HTTP conversion server in the camera
server to the web browser and then run on the web browser. The features of the Java
viewers are listed below.
Java viewers use the WebView-HTTP protocol for video transmission
and camera operation. They can penetrate firewalls and access
external sites.
Because Java viewers are automatically downloaded, they do not need
to be pre-installed on the user’s PC.
Java viewers run on a wide range of platforms.
e
Note
Because Java applets are downloaded each time you connect to the camera
site and view live video, the Java viewer startup time is longer than that for
the helper viewer.
4
Creating Web Pages
Java Viewer Types
The Java viewers include "LiveApplet", which has video display and camera control
functions, "Glimpse", which has only a video display function, and "PanoramaSnap", which
features a still image display function. Because the viewers all use the WebView-HTTP
transmission protocol, they can penetrate firewalls without requiring special settings.

Features of the Helper Viewer
The helper viewer is an application started from a web browser. Unlike the Java viewers, the
helper viewer must be pre-installed on the client's computer. The features of the helper
viewer are outlined below.
While the helper viewer must be pre-installed, once installed it launches
quickly and is stable to run.
The helper viewer uses both the WebView-TCP and WebView-HTTP
protocols and can penetrate firewalls to access external sites.
The helper viewer can be run as a standalone application.

Viewing Sample Pages
A number of sample web pages for video transmission are provided with the WebView
Livescope camera server. These sample pages can be viewed using the procedure given
below. Refer to these pages when you create your own web page.
Viewing the Pages
1
From the [Start] menu, select [Programs]-[WebView Livescope]-[Home Page Sample].
Alternatively, enter the camera server URL from your web browser. The URL is as
follows:
http://192.168.100.10*/-wvdoc-01-/SamplePages/index.html
* The underscored portion is a sample IP address. Enter the actual camera server IP
address.
Also, if the camera server's HTTP conversion server port number is 80, only the camera
server host name is required. If not, you must include the camera server host port
number (eg. 192.168.100.10:8080).

Using Java Viewers to Send Information
This section describes how to use a Java viewer to supply video images and provides examples of
applications.
Creating Web Pages that Use Java Viewers
When you use a Java viewer, the viewer applet used must be embedded in the web page
provided to the client. However, this is not especially difficult. A web page of this sort can be
created simply using the type of HTML coding normally used to embed an applet.
LiveApplet
<applet codebase=http://192.168.100.10* /
-wvdoc-01-/LiveApplet/" code="LiveApplet.class" width=450 height=380>
<param name=cabbase value="LiveApplet.cab">
<param name=url value="http://192.168.100.10* /">
</applet>
Glimpse
<applet codebase="http://192.168.100.10*/
-wvdoc-01-/Glimpse/" code="Glimpse.class" width=160 height=120>
<param name=cabbase value="Glimpse.cab">
<param name=url value="http://192.168.100.10*/">
</applet>
PanoramaSnap
<applet codebase="http://192.168.100.10*/
-wvdoc-01-/PanoramaSnap/" code="PanoramaSnap.class" width=600 height=250>
<param name=cabbase value="PanoramaSnap.cab">
<param name=url value="http://192.168.100.10*/">
</applet>
The parameters required by the applet are included between the <applet> and </applet>
tags.
The applet parameters other than the common applet parameters codebase, code, width
and height are coded using the <param> tag.
* The underscored portion is a sample IP address. Enter the actual camera server IP address.
Also, if the camera server's HTTP conversion server port number is 80, only the camera server
host name is required. If not, you must include the camera server host port number (eg.
192.168.100.10:8080).
82
e
Note
Shortening the Applet Download Time
You can reduce the time required to download an applet by archiving multiple class
files into a single CAB or ZIP file.
Using Internet Explorer
Internet Explorer supports compressed archive (CAB) files. WebView Livescope
provides the LiveApplet.cab, Glimpse.cab and PanoramaSnap.cab archives in the
folder used for applet installation.
<applet code="LiveApplet.class" width=450 height=380>
<param name="cabbase" value="LiveApplet.cab">
</applet>
● This "cabbase" parameter is ignored by browsers other than Internet Explorer.
Using Netscape Navigator
Netscape Navigator supports uncompressed standard ZIP files.
WebView Livescope provides the LiveApplet.zip, Glimpse.zip and PanoramaSnap.zip
files in the folder used for applet installation. These files should be coded inside the
applet tags and specified as zip files using the archive attribute.
<applet archive="LiveApplet.zip" code="LiveApplet.class" width=450
height=380>
4
</applet>
Creating Web Pages
● Navigator 4.x also supports compressed ZIP files, but uncompressed ZIP files should
still be used so that the applet will run on earlier versions (3.x).
Providing compatibility with Internet Explorer and Netscape Navigator
To ensure that the maximum possible number of clients can view the video images, the
applet tags should be coded so as to be compatible with both the mainstream browsers.
<applet archive="LiveApplet.zip" code="LiveApplet.class" width=
450 height=380>
<param name="cabbase" value="LiveApplet.cab">

show_toolbar
Yes
Specifies whether the toolbar area is displayed. The toolbar area is always displayed
unless the "off" setting is specified here. If "false" is specified in the "controllable"
parameter, this specification is ignored.
superimpose
Yes
This function superimposes a bitmap image on the video image. Specify "bitmap-filename,x.y". The
bitmap file must be a GIF-format file (transparent GIF images are supported). The "x" and "y"
parameters specify the coordinates at which the bitmap image is superimposed on the video image.
If these are omitted, the bitmap is superimposed in the center of the video image.
No
Sets the URL that specifies the HTTP conversion server and the HTTP conversion
server IP address and port number. Connection to the HTTP conversion server is
only performed if this parameter is specified correctly. The IP address and port
number specified in this parameter must match the IP address and port number
specified in the codebase parameter.
Yes
Specifies the video display size (in pixels). This parameter specifies the width. (The
height is governed by the width.) The display size can be set to values between 80
and 640. Any value can be specified as the width. The image height is calculated as
three-quarters of the width.
Eg. video_width="240" (height = 240 x 3/4 = 180)
No
Specifies the size of the area assigned for use by the applet (in pixels). If a value
smaller than the applet drawing area is specified, the applet may be displayed
incorrectly. If a camera control GUI is to be added (controllable=true), increase the
width by 130 and the height by 140.
Eg. For an image size of 320x240, specify width=450 and height=380.

open_image_time
When a startup image is specified in the "open_image" parameter, this parameter specifies the time
for which that image is displayed. The display time is strictly a guideline and is not exact. The unit
used is milliseconds (ms: 1/1000 sec.). The default setting is 0. The image is displayed until the first
live video frame appears. Values between 0 and 30000 (30 seconds) can be set.
95
■ Glimpse
Parameter
96
Can be set
Description
capture_size
Yes
This parameter specifies the size at which the image is captured. The following
settings can be specified: "640x480", "320x240", and "80x60". If this parameter is
omitted, optimum values for width and height will be set automatically.
code
No
Specifies the applet (Glimpse) file name. Code as "Glimpse.class". The applet
(Glimpse) is only downloaded if this parameter is specified correctly.
codebase
No
The directory in which applets are held. This parameter is coded in the following
format:
http://HTTP conversion server IP address:port number/folder/.
The "HTTP conversion server IP address" portion can be specified using the host
name, but because a security violation arises on some web browsers when the host
name cannot be referenced by DNS, always specify the IP address. The applet
(Glimpse) is only downloaded if this parameter is specified correctly. The default
folder specification is "-wvdoc-01-/Glimpse".
comment
Yes
Specifies the comment text displayed as an overlay in the applet window (Japanese
cannot be used). If this parameter is omitted, no comment is displayed.
hostname
Yes
Specifies the host name displayed on the applet (Japanese text cannot be used).
This name is used in messages as the host name during connection, etc. If this
parameter is omitted, no host name is shown.
show_counter
Yes
This function superimposes the frame count on the video image. Specify "on" or "off".
The default setting is "off".
show_hostname
Yes
sleep
Yes
This function superimposes the host name on the video image. Specify "on" or "off".
The default setting is "off". Note that this parameter is only valid when the
"hostname" parameter is specified.
Specifies the time interval for image updating (in milliseconds). Because the interval
used varies depending on the performance of the computer, the update interval
specified here is not guaranteed. If this parameter is omitted, the image is updated
every 5 seconds. Because the Glimpse applet is intended to be used for displaying
lists of multiple sites, parameters of this time are provided as a way of reducing the
load. Intervals between 0 and 300,000 ms (5 minutes) can be specified. If 0 is
specified, time interval adjustment is not performed.
url
No
Sets the URL that specifies the HTTP conversion server and the HTTP conversion
server IP address and port number. Connection to the HTTP conversion server is
only performed if this parameter is specified correctly. The IP address and port
number specified in this parameter must match the IP address and port number
specified in the codebase parameter.
width
height
No
Specifies the size of the area assigned for use by the applet (in pixels). In Glimpse,
because the applet area and the display area are the same size, you should specify
the width and height of the image itself.
Eg. For an image size of 320x240, specify width=320 and height=240.
Using Java Viewers to Send Information
■ PanoramaSnap

higher). If this parameter is omitted, "1" is used.
code
No
Specifies the applet (PanoramaSnap) file name. Code as " PanoramaSnap.class". The
applet (PanoramaSnap) is only downloaded if this parameter is specified correctly.
codebase
No
The directory in which applets are held. This parameter is coded in the following
format:
http://HTTP conversion server IP address:port number/folder/.
The "HTTP conversion server IP address" portion can be specified using the host
name, but because a security violation arises on some web browsers when the host
name cannot be referenced by DNS, always specify the IP address. The applet
(PanoramaSnap) is only downloaded if this parameter is specified correctly. The
default folder specification is "-wvdoc-01-/PanoramaSnap".
frame_name
Yes
Specifies the name of the frame used to display the captured image. If this parameter
is omitted, a new browser window opens and the image appears in that window.
Yes
Specifies the page displayed when a button is clicked. If this parameter is omitted, only
the still image is displayed. The page specified in the template_file parameter must be
stored in the same folder as the page that includes the applet. If the page is not found, a
browser page inclusion error occurs. Also, the frame used to display the page is the
frame specified in the frame_name parameter. If the frame is not explicitly specified in
frame_name, this parameter is ignored.
No
Sets the URL that specifies the HTTP conversion server and includes the HTTP
conversion server IP address and port number. Connection to the HTTP conversion
server is only performed if this parameter is specified correctly. The IP address and
port number specified in this parameter must match the IP address and port number
specified in the codebase parameter.
No
Specifies the size of the area assigned for use by the applet (in pixels). The
recommended settings are width=600 and height=250.
Because these settings vary depending on the type of camera and the visible range
settings, it is advisable to adjust them as you see fit.

Creating wvh Files
This section describes how to create the wvh files needed to launch the helper viewer
application.
Creation Procedure
1
a
IMPORTANT
Use a text editor to create a new text file and type the following into the text file:
(Example) 192.168.100.10 65310
192.168.100.10 65311
#WebView V3.0 wvh extension
wvhttp:192.168.100.10 80
● The first line is the IP address (or host name) of the computer running the video
server and the TCP port number used by the video server for internet services.
● The second line is the IP address (or host name) of the computer running the
camera control server and the TCP port number used by the camera control server
for internet services.
For the IP address, type in the actual camera server IP address (or host
name).
4
Creating Web Pages
● The third line is the extension used from WebView Livescope version 3.0. The
hash symbol (#) at the beginning of the line indicates that this is a comment line.
From the third line onwards, use the following format:
[Header]:[HostName][Port][Option]
The following can be specified as the header:
wvhttp:
This specifies the conversion server host name. If no conversion server is
connected, use just the header with no host name. To connect to the
conversion server for images only, specify "v" as an option. For a WebViewHTTP connection, specify "vc" as the option (can be omitted).
2
Save the text file, quit the text editor and create a wvh file by modifying the file name
and the file extension. You must always add the ".wvh" extension (eg.
"WebView.wvh"). You should also save the wvh file in a folder close to the web page
being created.
99
Example of Creating a Web Page that Uses the Helper Viewer
This section describes an example of the creation of a web page that uses the helper
viewer.
The launched and
displayed helper
application
Click the link to launch the
1 helper application.
100
Using the Helper Viewer to Send Information
The images and text on the web page include tags that link to wvh files.
1
<A HREF="WebView.wvh"> Watch the video!!</A>
When you click on "Watch the video!!" in the sample web page shown above, a helper
application is launched and you can receive video signals from the camera.
e
Note
Using the Automatic Sample Generation Function to Create a Web
Page
By using the Automatic Sample Generation Function provided in the HTTP
conversion server in the camera server, you can create a web page that uses
the helper view without having to set up the web server or create wvh files.
The HTML coding is shown below.
1
<A HREF=http://192.168.100.10*/-wvdoc-01-/SamplePages/Helper/
4
default.template.wvh>
Watch the video!!</A>
Automatic Sample Generation Function
Creating Web Pages
If you use this function, you do not need to add a web server MIME setting for
saving data transmission pages, which makes this a very useful approach for
users who save their web pages on their service provider's server.
This is a function that automatically modifies sample page template files
stored on the camera server based on the camera server settings and sends
the modified files to the client. This allows the sender to distribute video to
clients with the minimum of effort.
* The underscored portion above is a sample IP address. Enter the actual camera server IP
address.
Also, if the camera server's HTTP conversion server port number is 80, only the camera server
host name is required. If not, you must include the camera server host port number (eg.
192.168.100.10:8080).
101
Using a Browser Alone to Send Video
The WebView-HTTP protocol can be used to provide video images directly from the camera to a
browser. This section describes an example in which the protocol is used in this way.
Displaying Live Video
as Still Images During Access
Images shot by the camera can be provided as still images each time the client accesses
the web page that provides the images.
<IMG SRC=http://192.168.100.10*/-wvhttp-01-/GetStillImage>
or
<IMG SRC=http://192.168.100.10*/-wvhttp-01-/GetOneShot>
Displaying Live Video as a Movie with
a Specified Number of Frames During
Access
The Server Push format provided as an extended function by Netscape Communications
Corp. can be used to transmit multiple-frame images. However, these images can also be
displayed on browsers other than Netscape Navigator. In the coding example below, 100
frames of live video are transmitted when the client accesses the camera server.
<IMG SRC=http://192.168.100.10*/-wvhttp-01-/GetOneShot?frame_count=100>
102
Displaying Live Video from a Specified
Angle as Still Images
By specifying the camera angle as a parameter in the HTML code beforehand, you can view the
image at a specified camera angle. The example below displays a still image shot with the
camera panned right by 40° and tilted down 10°.
<IMG SRC=http://192.168.100.10*/-wvhttp-01-/GetStillImage?p=40&t=-10>
■ GetStillImage Parameters
Parameter
Description
Specifies the camera pan angle (VC-C4: -100 to 100; VC-C4R: -170 to 170; VC-C3: -90 to
p (pan)
90; VC-C1: -50 to 50).
Specifies the camera tilt angle (VC-C4: -30 to 90; VC-C4R: -90 to 10; VC-C3: -30 to 25; VCt (tilt)
C1: -20 to 20).
Specifies the camera zoom ratio (VC-C4: 10 to 126; VC-C4R: 10 to 126; VC-C3: 10 to 101;
z (zoom ratio)
VC-C1: 10 to 74).
Specifies the backlight compensation (on: backlight compensation used; off: backlight
b (backlight compensation) compensation not used).
Specifies the video image size (640, 320, 160 or 80).
seq
Allows any number to be specified to avoid displaying old images (numeric value).
cache_id
Displays images cached in the server (camera number).
c
Caution
● If old images are displayed, you can prevent this recurring
by specifying a sequence number in the seq parameter.
● If the camera angle is specified, the image is not displayed
until the camera operation has been performed.
Consequently, on pages that are frequently accessed, user
wait time will often increase. When this is likely to occur,
specify the cache_id parameter. Images cached in the HTTP
conversion server can be retrieved without operating the
camera. (The cache is valid for one minute.)
4
Creating Web Pages
v (image size)
* The underscored portion is a sample IP address. Enter the actual camera server IP address.
Also, if the camera server's HTTP conversion server port number is 80, only the camera server
host name is required. If not, you must include the camera server host port number (eg.
192.168.100.10:8080).

Chapter 5
Still Image Recording Service
This chapter describes how to set up a still image storage service that
uses the upload server functions.
Still Image Recording Service
The Still Image Recording Service is made possible by the upload server running on the WebView
Livescope camera server. This service stores images according to a preset schedule and
automatically uploads those images to the web server. This provides a low-cost way of sending still
images since a permanent internet connection is not required.

The collected still images and HTML pages are automatically uploaded
to the web server running the FTP server. Uploading to the FTP server
can be performed via a LAN or a dial-up connection.
The web server runs on the same machine as the camera server to
permit still image distribution.
After uploading, CGI commands can be used for web server calls.
The camera server does not require a permanent internet connection,
allowing low-cost operation of a still-image camera site.

Using the Still Image Recording Service to Send Information
When the Still Image Recording Service is used to provide video images, image are shot according
to the specified schedule and those images are then uploaded to the web server. When this occurs,
successive web pages must be generated to include the images. Accordingly, WebView Livescope
has an "Automatic Page Generation Function" that automatically generates and uploads web pages.
This function can be used to send stored images over the web.
Sample Pages
First, refer to the sample pages. See P.80 for information on how to view
sample pages.

uploaded.
2
This file displays the links to stored images shown in the left frame. Because the
number of images stored increases when images are uploaded, this file is updated
(added to) each time an image is uploaded.
This file is the page that displays stored images in the right frame. Because this file is

the WebView camera server.
Specify the settings below to use the WWW server function.
Selecting the Settings
1
Make a schedule reservation in the Still Image service settings (see P.107 onwards).
Leave the directory for the upload place and the upload place folder for the schedule
set to the default settings.
- "Upload place" -> "Directory"
C:\Program Files\Canon\WebView\DownloadRoot\Upload
- "Schedule (reserved schedule name)" -> "Upload" -> "Upload place"

c
Caution
2
If the WebView camera server is not installed in the above location
(C:\Program Files...), change the setting to match the folder in which the
server was installed.
The sample pages can be viewed at the following URLs:
● Automatically generated page

* The underscored portion is a sample IP address. Enter the actual camera server IP
address.
Also, if the camera server's HTTP conversion server port number is 80, only the
camera server host name is required. If not, you must include the camera server
host port number (eg. 192.168.100.10:8080).
120
Using the Still Image Recording Service to Send Information
When a Remote Web Server is Used to Send Automatically Generated
Pages
If a web server is set up separately from the WebView camera server, you can use the
sample pages (see P.80) by copying the required files from the WebView camera server to
the web server and then modifying some of the files. Because the FTP server is used for
uploading, the FTP server and web server must run on the same machine.
Selecting the Settings
1
Make a schedule reservation in the Still Image Recording Service settings (see P.107
onwards). For the files in the example described below, set the web server home
folder to WWWRoot, the IP address to 192.168.100.10, and the port number to 80.
2
Copy the "Upload" folder in the "SamplePages" folder in the webview server home
folder (default: C:\Program Files\Canon\WebView\DownloadRoot) into the WWWRoot
folder.
Create a new image storage folder called "image1" in the copied "Upload" folder.
3
Modify the HTML file coding so that it will run the applet sample pages. Open the
applet.template.html and script.template.html files in the respective "AppletSample1/2/
3" folders in the copied "Upload" folder and replace the web server IP addresses and
5
port numbers in the following:
http://_HTTP_SERVER_HOST_AND_PORT_/-wvdoc-01-/SamplePages
http://192.168.100.10/
c
Caution

Because the applet may not run if you use a host name as the IP address,
always specify the IP address.
The sample pages can be viewed at the following URLs:
● Automatically generated page
http://192.168.100.10/Upload/Image1/index.html
● Applet sample 1

Applet Samples
Sample pages that include applets designed for viewing images and observing the results
are provided with the WebView camera server.
Applet Sample 1: Link List
To reduce the time involved in searching a large number of images for the image you want to
view, this sample applet allows you to first index the images by date and caption, then list
images in the selected index, and then display the images and information.

When the user selects one of the items in the list
displayed in area
displayed in area
, the stored image is
. The image display HTML file
for displaying the stored image in area is
automatically created by the upload server.
e
Note
To use the image display HTML file, the name of the image display HTML file
to be viewed must somehow be obtained. The upload server creates image
display HTML files using the "Upload file name" setting specified in the
WebView Livescope manager's "Still Image Service". (See P.113 for more
information on the "Upload file name" setting.)
In this sample, the JavaScript program in script.template.html automatically
generates the file name using the same algorithm as the upload server.

Troubleshooting
Problem
I cannot access the camera server from a network.
Solution
Camera server
● Restart the PC on which the camera server is running.
● Check the Windows NT "Network" settings.
Check that the IP address, subnet mask, gateway and DNS server settings are entered
correctly. Always restart your PC after you change the network settings.
● Check that the Ethernet cable is connected correctly.
Viewer
● Check that the camera server IP address (or host name) is specified correctly.
● If the connection uses the WebView HTTP protocol, you can only penetrate firewalls for access
if the proxy server is set up correctly. Specify an HTTP proxy that uses an ordinary web
browser.
● If the connection uses the WebView TCP protocol, you can penetrate firewalls without using a
proxy. You can set up a TCP proxy, but the proxy must use the WebView dedicated proxy
software. (See P.40 in the Viewer manual.)
Problem
Images are not displayed.
Solution
Camera server
● Check that the camera is switched on.
● Check that the video cable is correctly connected to the camera and PC.
● If the input port connection position for the video capture board is incorrect, the image is
displayed in blue with the Osprey-100 and in black with Meteor boards. If this occurs, check that
the input port is specified correctly (see P.40).
● To improve the quality of the image, check the image settings (see P.34).
Viewer
● For the helper viewer, check that the viewer has been installed correctly (see P.21).
● For a Java viewer, check operating environment settings such as the web browser version. Visit
the WebView World web page for the latest information. URL: http://www.x-zone.canon.co.jp/
WebView-E/index.htm.
Problem
I can't control the camera.
Solution
Camera server
● Check that the camera is switched on.
● Check that the RS cable used for camera control is correctly connected to the camera and PC.
● Check that the correct serial port is being used for PC connection and that the serial port in the
server settings panel is correct (see P.39).
● If field of view restrictions are specified, check the settings (see P.44).
● If the VC-C4 camera has been connected using a cascade connection, check that the other
cameras are on and that the RS cable has been connected properly. (If a camera connected in
a cascade connection is Off, it will take approximately one minute after the camera is switched
On until it is ready to use. This also applies when there is RS cable trouble.)
132
Problem
The helper viewer won't launch.
Solution
Camera server
● Check that the MIME type settings for the helper viewer in the web server are specified correctly (see P.98).
● Check that the server wvh file is coded correctly (see P.99).
Viewer
● Check that the viewer has been installed correctly (see P.21).
Problem
The server load is at 100%.
Solution
Camera server
● If you are using an Osprey-100 video capture board and have selected streaming capture,
images are transmitted with maximum efficiency but the load on the server is increased and can
adversely affect other processes. If this is occurring, use frame capture mode or reduce the
transmission frame rate.
Problem
The results of access log analysis are not displayed correctly.
Solution
Camera server
● There may be a problem with the working data created by access log analysis tool. Use the
access log analysis settings to delete the damaged working data and then restart your web
browser (see P.73).
Problem
Solution
I am using the version 3.10 helper viewer to connect to an older version of the camera
server.
● The version 3.10 helper viewer can be connected to an older version of the camera server, but
the following restrictions then apply:
- If you are connecting to a version 1.x, version 2.0 or VB101, panorama images cannot be
displayed. However, the panorama window can be used to control the camera.
- If you are connecting to version 2.0, the version 2.0 preset function cannot be used by the
version 3.10 helper. However, you can switch cameras.
I am using an old version of the helper viewer to connect to the version 3.10 camera
server.
Solution
● Old versions of the helper viewer can be connected to the WebView version 3.10 server, but the
following restrictions then apply:
- The version 1.0 helper cannot use the preset function, camera selection function or panorama
function.
- The version 2.0 helper cannot use the preset function or panorama function.
Problem
The message "Failed to connect" appears when you try to connect to the camera
server with WebView manager.
Solution
● When the connection is from a remote, check that the host name and port number are correct.
● When the connection is over a camera server machine, check that the network settings for the
machine are correct.
