number of users viewing on the network, even if the parameters have been initially

finely tuned. Performance will also suffer due to poor connectivity because of the

network’s burst constraint.

Best Quality Images

To have the best video quality, set “Fixed quality” at “Detailed” or “Excellent” and adjust

the “Maximum frame rate” to match your network’s bandwidth. If your network is slow

and you receive “broken” images, go to the TCP or HTTP protocol in “MPEG-4 Protocol

Options” and choose a more appropriate mode of transmission. The images may suffer

a time delay due to a slower connection. The delay will also increase with added number

of users.

Somewhere between Real-time and best Quality Images

If you have a broadband network, set “Fixed quality” at “Normal” or better, rather than

setting “Constant bit rate.” You can also fix the bandwidth according to your actual

network speed and adjust the frame rate. Start from 30 fps down for best results but

do not go below 15 fps. If the image qualities are not improved, select a lower

bandwidth setting.
