Chapter4 Using IP/TV Viewer
Playing a Program
Up to four viewer windows that are open at the same time are supported. Ho wev er ,
IP/TV does not limit the number of viewer windows you can open at one time. If
you have subscribed to more than four programs that run simultaneously, you will
only receive four programs at one time. When one program ends a nd you cl ose
that viewer window, another program will begin playing.
Note Displaying multiple IP/TV viewer windows may result in poor video
performance, especially on less powerful computers. If you want t he be st
possible quality, stop playing all IP/TV programs you are not watching and
close other applications that you are not using.
IP/TV Viewer performs best on faster machines, and when receiving data through
less congested networks. When these conditions are not met, IP/TV provides
lower-quality reception.
If the video you are watching appears jerky and you notice that your c omputer has
a lot of disk activity, your computer may be running low on memory.
Here are a few suggestions on how to get the best performance from IP/TV Viewer
on your computer:
•Close applications you are not using, especially applications that require
significant bandwidth on your local network.
•IP/TV supports multiple windows; however, you may want to close these
windows rather than minimize them to receive multimedia streams.
•Trade sound quality for better video quality.
•If you only want to listen to a program while you are working in an othe r
program, you may want to disable the video. See the “Advanced Topics”
section on page 4-35.
•If the program is an 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. Consult the contact
person on the MBone program contact list regarding the quality of the MBone
program.
•Use the Pause button if video is not needed.
