One SDK Manual
3. Minimum System Requirement
Hardware: Pentium4 CPU based PC, one empty PCI slot.
Software: Microsoft Windows XP, Windows Vista or Windows 7, DirectX 9 and above. Please note
although running the main Voverlay.exe application does not require it, running the sample
VoverlayVB.exe application will need the Microsoft .Net Framework 3.5 and above to be installed.
4. Hardware Installation
Un-plug the PC’s power cable, open PC case, locate a free PCI slot, plug in the VOVERLAY card and
screw it firmly to the back-panel.
Plug in video cables between the external video input/output devices and VOVERLAY. To view the
incoming video mixed with overlaid text/graphics, eternal TV monitors need to be connected to the output
sockets of the VOVERLAY card. Alternatively, video capture cards like Inventa MPEGIO/USBOSDM2
etc. can be used to accept video output signals from VOVERLAY to view the video with overlaid
text/graphics.
5. Software Installation
Software installation has two steps: device driver software installation and application software installation.

5.1 After hardware installation, the MS Windows will inform that new hardware is found:
5.2 Put the Voverlay installation CD into PC’s CD/DVD drive, click “Next” button, let Windows search
for device driver specifically from the “driver” folder on the installation CD Disk. During the driver
installation, ignore those warnings claiming the device driver “has not passed Windows Logo
testing…” etc, press “Continue Anyway” to keep going, until the driver is installed, then check the
Windows’ “ControlPanel” to make sure the
“System->Hardware->DeviceManager ->Sound, video and game controllers” category has a device
driver line “Voverlay ver b for windows XP/Vista/7” listed for every Voverlay card there without
question mark or exclamation mark:

When device driver has been installed properly, Windows will have a pop-up message box at the
lower right corner of the screen:
Please note: after re-installing MS Windows on a PC with VOVERLAY card remaining seated
in PCI slot, one “Multimedia Controller/PCI Device” or similar line will appear in the
Windows’ ControlPannel->System->Hardware->DeviceManager window, preceded by a
yellow question mark or exclamation mark, since Windows will not(cannot) install the device
driver software. This item will need “update driver” operation(right-mouse click then select
“Update driver…”) to install the proper driver software from the “driver” folder on the Setup
CD, before the VOVERLAY card and application software can be used properly. Alternatively,
you can delete this question-mark/exclamation-mark preceded item(right-mouse click them
then select “Uninstall”), highlight the PC’s name in the DeviceManager window then select
“Scan for Hardware Changes”:
