The Internet contains countless valuable multimedia and technical materials. Quite often it is an urgent requirement for users to be able to provide real-time video, audio and animation playback for free or at a low price. For the current bandwidth and modems used, it is not possible to broadcast digital movies in real time, to broadcast the Vienna New Year’s Concert or the NBA Finals , Many programs allow free or low-cost downloads, but download time is daunting, one of the important reasons for the speed bottleneck is Modem.
