tically reestablished

difficulties or because
the VB-C50FSi/VB-C50Fi is rebooted. If reconnection fails, another recon\
nection attempt is made
30 seconds later. If an audio connection is current when the connection \
is aborted, the audio
connection is also automatically reestablished.

Creating Web Pages forVideo Distribution
This chapter describes how to use the VB-C50FSi/VB-C50Fi
to webcast information.
Picture data can be distributed in various ways, including
displaying video or still pictures and displaying multiple
images on a Web page.

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-C50FSi/VB-C50Fi 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-C50FSi/VB-C5\
0Fi in response to
the request in step  3 and the video is distributed.
To distribute picture data by VB-C50FSi/VB-C50Fi, you create a dedicated\
 Web page. The viewers
that can be used with the VB-C50FSi/VB-C50Fi are “Viewer for Java (w\
ith 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-C50FSi/VB-C50Fi and can be accessed \
from the URL below.

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-C50FSi/VB-C50Fi ( → P.3-6).
Note
The VB-C50FSi/VB-C50Fi includes a built-in Web server. If the content of\
 the Web
pages used for distributing videos is stored onto the flash memory in th\
e VB-C50FSi/
VB-C50Fi, the VB-C50FSi/VB-C50Fi can be used by itself for distributing \
Web pages
and videos over the Web. Please refer to page 5-8 for procedures on how \
to save
Web page data.

There are 2 types of viewers: the Viewer for Java and the Viewer for PC.\
For a detailed explanation of the Viewers, please refer to “Viewer So\
ftware Overview” (→ P.2-14)
or to the Viewer Software User’s Manual (Viewer-E.pdf) on the CD-RO\
M.
Viewer for Java
The Viewer for Java provides 2 types of viewers: LiveApplet containing v\
ideo display and camera
control functions, and Glimpse containing a video display function. Beca\
use both viewers use the
WebView-HTTP transfer protocol, data can pass through firewalls with no \
need for special settings.

. Application examples
are also given.
Using the Viewer for Java to Distribute Videos
Using the Viewer for Java to Create a Web Page
When you use the Viewer for Java, the viewer applet to be used must be i\
ncorporated into the
Web page you provide. However, this is not especially difficult. The pag\
e can be created using the
HTML normally used to include an applet.
LiveApplet

Saving Web Page Data
The VB-C50FSi/VB-C50Fi is equipped with a Flash memory where Web page da\
ta can be saved.
Data is saved by transferring the data files using FTP. The data is plac\
ed as a file under /usr/html/
local.
Device File system URL(accessed by an ftp client) (accessed from a Web browser)
On-board flashftp://IP address/usr/html/local http://IP address/local/
memory
Note
● Output performance may suffer if there is insufficient free space in the\
 on-board
file system. Ensure that only the minimum amount of data required is sto\
red in the
on-board file system ( → P.3-28).
● Using “Restore Settings” ( → P.3-29, 7-21) deletes all saved data. Back up your
data before using this function.
