ok read this at the mean question belowe this and tell me what did it meen slowe upload speed?

Question

If the image quality is poor while transmitting video over the Internet using video enabled programs such as MSN Messenger, Yahoo! or AOL Instant Messenger, your connection speed to the Internet directly affects the image quality of the transmitted video. Corporate LAN, DSL/cable modem connections will result in the best image quality experience, while dial-up connections may result in choppy and overall poor quality because of the slower connection speed. Even broadband connections such as DSL/cable modem may experience choppy video at times because of Internet traffic or slow upload speeds. If the image appears clearly in the camera software, most likely your Internet connection may be responsible for the poor image quality in your video program.

Answer 1

Most DSL lines have very high DOWNLOAD speeds, that means things coming into your computer are very fast.

However, most also have limited "upload speeds" -- the speed you send data out to the internet.

With a web cam the outbound or "upload speed" is critical. If that speed is too low your images will be degraded due the the "outbound" speed of the webcam signal.

Some typical DSL speeds are 1.5M download / 256 upload
or 3M download / 384 upload etc so you see that the outbound data from your machine is MUCH slower than the information you receive. If it is too slow, the "viewer" of your webcam over the internet will get a "choppy" picture.
