Experience choppiness in Netmeeting or InternetPhone
or other 3rd party conferencing software when you do
video conferencing.
If you experience choppiness in Netmeeting or Internet Phone, the
followings may be the possible cause:
1. Check the modem connection.
You need to check whether your modem connection speed
has dropped, or the modem connection speed at the other
end may be low. Your connection will depend on your ISP
(Internet Service Provider). Busy traffic during peak hours
may reduce the connection speed.
2. Check whether full-duplex audio is enabled.
If you use Internet Phone and have enabled your sound
card's full-duplex option, you can listen and talk at the same
time (e.g. standard telephone conversation). In order for you
to do this, the person that you are talking with also needs to
have a full-duplex card. Otherwise, you will experience
intermediate pauses during conversation.
If the other person uses a half-duplex sound card, you must
wait for the other person to stop talking before you can talk
(e.g. talking on walkie-talkie).
3. Check other application driver is enabled.
If you had installed Yamaha SoftSynthesizer, check that
your sampling rate is not at 44KHz. It is recommended to
use 22KHz sample rate for video conferencing. Otherwise,
disable the Yamaha SoftSynthesizer driver. Reboot the
system for the changes to take effect. This will improved
any choppiness.
4. Check Video is enabled.
If you have setup a video camera together with your audio
card, you will experience choppiness because more data are
being sent out to the network (internet).
