- >>What do I need for a video conference?
A video conferencing system, a monitor and an ISDN connection. - >>My business partner in London has a video conferencing system of another manufacturer. Can we still hold a video conference?
Yes, naturally, this is not a problem, the H.320 Standard was introduced for that purpose. For more details on this, write to info@vidofon.de - >>About 4 years ago, the picture quality was still not good. That has changed in the meantime. What does that depend on?
The picture quality during transmission depends in the first place, on the bandwidth. The higher the bandwidth, the better the transmission quality. The bandwidth increases with the number of ISDN lines used and subsequently, so does the quality. The coding algorithm was also permanently optimized regardless of the bandwidth. Today, this essentially provides for a sharper picture. - >>Can one set the bandwidth?
Yes. - >>What about the data security? Can one hack the conference connection from outside?
No, the data is sent encrypted and only the partner system can decrypt it. 
top- >>Does the system use the Internet as transmission medium?
The Internet can be used depending on the connection and signal, however it cannot be guaranteed for quality of service. - >>How many ISDN connections can I use?
You can use up to 12 ISDN connections or one primary-multiplexer connection (S2M) respectively. - >>What costs will I incur during the connection?
Normal telephone costs, multiplied by the number of occupied lines. We will be glad to help you. For more details, write to us at info@vidofon.de - >>We will use our own company network. Can I use the video conferencing in the network too?
Yes, most systems are network compatible. - >>Instead of using the ISDN number, can I also specify an IP address?
Yes, if the system has IP functionality. - top
- >>During the conference with my partner in New York, I want to play a video cassette. What do I have to do?
The video recorder connector is normally located at the back panel of the video conferencing system. Connect both devices and if needed, use the remote control to switch to the video recorder. - >>What is the required bandwidth to integrate videos from a cassette into the conference?
You must use at least 2 ISDN lines, we recommand 3-4 lines. - >>Can I hold a video conference with multiple stations simultaneously?
Yes, with a multipoint-compatible system. - >>What is multipoint?
Multipoint means multiple stations simultaneously. In a multipoint conference, you are connected to multiple stations simultaneously (e.g. up to 4 stations) - >>My presentation comprises PowerPoint slides. How can I integrate them into the conference?
Use a network card to connect your laptop with the video conferencing system, and transmit the slide directly in your video conference. - top
- >>What is a MCU?
A MCU is a "Multipoint Control Unit". Hence, it is a kind of "Bridge", which multiple stations can dial into in order to hold a conference together. - >>Does ViDOFON supply a complete solution?
Yes.
