NewTek TriCaster 2 Elite (3 RU) - Manual (Page 207)

For a system running Apple’s OS X ® :
1. Double-click Terminal in the Applications\Utilities folder.
2. Type the following command into the Terminal (without quotations) and then add the IP number,
and press
Enter :
“ping – c 4 ipnumber. ”
(So, for example, you might type: ping – c 4 192.168.1.101)
The response will be similar to the Windows ® example described above. Again, a ping failure indicates a
problem with the network connection.

SPEED TESTS
Are you sure your upload bandwidth is adequate to the bitrate you’ve set for your stream? Why not test and
make sure? Again, a number of websites provide free speed testing. These will give you a basic idea of what
your local bandwidth really is. One site which provides a list of online speed test resources is:

18.8.3 WHERE IS THE PROBLEM?
With regard to streaming issues, don’t overlook the fact that your NewTek live production system is just one
of the pieces of the puzzle. There are many others that are just as important. One useful thing to try is to
check the streaming file. Archive the streaming output file locally, and then examine it to see if it has any
problems. This file corresponds exactly to what the encoder is sending the downstream server. In cases of
sync problems, low frame-rate problems, audio popping problems, etc., if it's an encoding issue, the problem
will be seen in this file. On the other hand (if the file looks good), then the issue has to be after the encoder
(perhaps a network problem or CDN configuration mismatch).
