A: Yes. Even though you do not have a camera, your XtX can receive
video images of others.

A: No. If you download a demo version of XtX from our web
page, you can try it out for about 14 days from its installation
or until its master expiration date whichever comes fast. Please
note that the demo is only allow once (14days) per PC which XtX
is installed. After expiration of the Demo, 2nd download and installation
is not permitted. We encourage you to purchase
it after the Demo.

Q: Does XtX Software support Windows 2000?
A: Yes. Current version of XtX 2.1 works on Windows 2000.
Q: Does XtX Software support Firewall?
A: No. Due to unique user network envirnment, it is not cost
effective for us to provide firewall option.

Q: What other video input devices does the XtX support?
A: XtX was developed to Microsoft's Video for Windows API specifications,
and it supports any standard Video for Windows capture device.
You can use a parallel port camera such as Connectix (Logitech)
QuickCam or a video capture card such as WINNOV, Diamond Multimedia,
Philips, etc.
Q: Does XtX work over modems?
A: Yes. XtX works over a 28.8 kbps modem connected to the Internet.
Q: Will XtX operate over ISDN?
A: Yes. XtX supports video conferencing over any Internet connection
of 28.8 kbps or higher including ISDN, ADSL, Frame Relay, T1 or
LAN as long as TCP/IP protocol is supported.
Q: How many users can be connected simultaneously using XtX
Software?
A: The current XtX supports point-to-point and Multi-Point videoconferencing
up to 10 participants.However, please remember that more users
are conneted, it result in poorer total performance when Internet
access speed is limited.
Q: How can I connect to more than two
persons simultaneously using XtX?
A: Simply keep calling one person after another. You do not need
to disconnect a person you have already connected to prior to
calling an additional person. Please remember that up to three
user conferencing is recommended for 28.8 kbps Internet connection.
If you have a much faster access to the Internet, you can connect
up to 10 persons. Since XtX dose not use multicasting technology
in order to make more than two user conference, each conference
participants have to make own connections among each other.
Q: What is multicasting?
A: Multicasting is the ability to send a single data stream to
many computers. CU-SeeMe and some other Internet videoconferencing
software utilize this technology with a reflector or server. However,
XtX does not use this technology to achieve Multi-Point connection.
Q: Does XtX support H.320, H.323, H.324?
A: No. Currently XtX dose not support these standards. Often
times, even if software become compliant there is no guarantee
for connectivity among other compliant software due to differences
in implementation methods.
