Canon VB101 appendix Broad band Video Distribution Function, Remote camera control from the viewer

Features of the VB101

The VB101 is a system that distributes live videos via the Internet or an Intranet. It can be used in a wide

variety of applications such as distributing live videos or monitoring from a Web site. The system is

configured of the VB101 and viewer software. Please use the supplied viewer software to view videos

distributed from the VB101 or to control a camera.

■Broad band Video Distribution Function

Video can be captured at a maximum of 30 fps. Motion-JPEG is used to compress the video

images. The network auto switches between Ethernet 100 MBPS and 10 Mbps, and if a PC card

modem is used, the analog public line network or the PFS network (PIAFS) can also be used.

Since video quality (1-99) and the frame rate (0.1-30 fps) can be freely set, video can be

distributed under conditions that best suit the network bandwidth.

■Simultaneous video reception by up to 40 users

Up to 40 clients can view videos simultaneously with a single VB101 unit.

■Remote camera control from the viewer

Two types of viewer software are provided: Helper Viewer and Java Viewer. These viewers can be used to freely control the angle (pan and tilt) and the zoom magnification of cameras installed in a remote location, enabling viewing videos with plenty of ambiance.

■Control for up to 4 cameras

Up to 4 video cameras can be connected to the VB101, and videos that you view can be switched from the viewer. If Canon Communications VC-C4/VC-C4R cameras are used, you will be able to control all cameras (using the cascade function of the VC-C4/VC-C4R).

■Panorama picture creation function and various settings

The camera's entire recordable area can be created as a panorama picture and saved. The saved picture can then be used to easily and visually set view restrictions and presets.

■Camera position preset function

When presets such as camera angles (direction in which camera is aimed or zoom position) are stored in advance, the camera can be controlled by simply selecting the desired preset from the viewer. Up to 8 sets of presets can be stored.

■View restriction function

Restrictions can be applied to zoom magnifications and angle settings to prevent viewers from seeing certain camera angles. When using the VB101 to operate a fixed point camera over the Internet, for example, it is possible to consider privacy when distributing videos (page 1, "Request Concerning the Disclosure of Live Pictures").

■Built-in Web server and FTP server

The VB101 has a built-in Web server. If Web page data is written onto a flash memory card (sold separately), the VB101 will be able to distribute Web pages and videos over the Web. Since the VB101 also has a built-in FTP server, Web page data can be sent from a remote location as a file (FTP).
