Table 4-5 Indicator Colors (continued)

Color

Meaning

 

 

Red

Reception quality is poor. Video may be very jerky and audio

 

may not be clear.

 

 

Gray

Insufficient data has been reported for IP/TV to display quality

 

levels. This indicator turns gray for a few seconds after a video

 

window is opened, or if transmission is interrupted.

 

 

When IP/TV Viewer performance degrades for no apparent reason, you can use the reception quality indicators to determine whether the problem is local to your computer or common to other computers viewing the same program:

If both indicators show poor reception quality levels, the problem is also detected by most or all of the computers viewing the same program. The problem is probably caused by a fault either in the server that is transmitting the program or in the network itself.

Contact the system administrator responsible for the server or a network manager for assistance.

Note If the program is an Internet-accessed MBone session, the cause of poor reception might be external to your corporate network, and thus beyond the ability of your system administrator or network manager to correct.

If the left indicator shows low reception levels while the right indicator shows normal levels, the problem is likely due to a fault somewhere with the local network or your computer.

Note If your computer does not meet the hardware requirements listed in Chapter 2, “Installing IP/TV Viewer,” your system may have insufficient processing power for the program you are viewing.

If these tips do not resolve the problem, contact your system administrator for assistance.
