Web Pages for Video Distribution
If you select a link requesting video in step  1, a file that includes the IP address information for the
VB-C50i/VB-C50iR is sent from the Web server in step  2. If you are using the Viewer for Java, the
applet is downloaded to the viewer PC from the VB-C50i/VB-C50iR in respo\
nse to the request in
step  3 and the video is distributed.
To distribute picture data by VB-C50i/VB-C50iR, you create a dedicated W\
eb page. The viewers
that can be used with the VB-C50i/VB-C50iR are “Viewer for Java (wit\
h 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 for the viewer.
The above page is built into the VB-C50i/VB-C50iR and can be accessed fr\
om the URL below.
http://
192.168.100.1*/
* The underlined portion is a sample IP address. Enter the actual IP addre\

Web Pages for Video Distribution
Tip
You can use the Language setting function for the Browser to create a mu\
lti-lingual
Web site. For example, if you set the French-language top page as index-\
fr.html and
the English-language top page as index.html and supply users with a URL address
terminates in slash, such as http://
192.168.100.1/sample/, the server will transmit a
file that corresponds with the language setting for the Browser. For fur\
ther information
on the Language setting function for the Browser, refer to the Browser H\
elp. * The underlined portion is a sample IP address. Enter the actual IP add\
ress set for the VB-C50i/VB-C50iR ( → P.3-6).
Note
The VB-C50i/VB-C50iR includes a built-in Web server. If the content of t\
he Web
pages used for distributing videos is stored onto the flash memory in th\
e VB-C50i/
VB-C50iR, the VB-C50i/VB-C50iR can be used by itself for distributing We\
b pages
and videos over the Web. Please refer to page 5-8 for procedures on how to save
Web page data.
