It is unsymmetrical as the user accesses the Internet Data, which requires higher speed in down stream and less speed in up stream. But the traditional correspond device and network are based on symmetrical mode. Under such symmetrical condition, the percentage of utilization of Internet resource and communication facilities is very low. And it does not meet the needs of downloading the content-rich book, software and audio data through the way of dialing to access Internet.
DVB Satellite and Cable TV Broad Band IP Access System, which are based on the unsymmetrical mode, totally different from the traditional alternate mode, greatly improve the transmission speed and save the cost and bandwidth.
