Abstract: This paper studies and analyses the video software and its transport character. With the result of the transport character it makes a little tool to test the transmission of ADSL network by end to end. So it draws some conclusion of the video software’s character and its reciprocal condition with ADSL network. It verifies all these conclusions by real test.
