The system can locate on the entrance line of the video website and broadcasting network，run independently and stand guard its entryway to ensure that no illegal video can be send into the network even though the sending systems be hacked. Moreover，the system can locate on carrying network line and provide solutions for supervision of video fragmentation under multiple-screen fusion situation and copyright protection on transmit line in real time.
