With the VSS-1 system, the video received from a remote Skype video call shows on the big screen in conference room . . .

Here’s Skype’s description/definition of  some of the issues relating to video Quality

video resolution of the three types of video cameras that Skype can support and that will appear on the conference room screens –

HD-capable, High Quality & Standard Quality.

1. HD-capable - Make Skype video calls in Hi-Definition – in geek-speak that’s 1280 x 720 pixel resolution at up to 30 frames per second.

2. High Quality - See smiles and waves in High Quality Video –  VGA quality with 640x480 pixel resolution at up to 30 frames per second. Great because: You can increase the size of your video call window without losing picture quality.

3. Standard Quality - If you’re just starting out these webcams are perfect. Great because: The simplest and most cost-effective solution for making video calls from Skype.

So one of the key factors affecting video quality is the camera that’s being used at the remote Skype sites.

Another key factor is the Available Bandwidth on the link between the sites.
