description The invention discloses a 4G network based end-to-end high-definition video safe transmission system and method. The system comprises a video acquisition terminal, a video receiving terminal and a server terminal, wherein the video acquisition terminal is used for acquiring video image signals and is provided with a TF video encryption card which is used for carrying out video streaming encryption processing to the acquired video signals; the video receiving terminal is used for receiving video streaming data sent by the video acquisition terminal through 4G network; the server terminal comprises an NAT traversal server and used for establishing a 4G network based encrypted tunnel between the video acquisition terminal and the video receiving terminal and the video acquisition terminal and the video receiving terminal transmit the video streaming data through the IP encrypted tunnel. In the invention, through encrypting a video source with a TF card and by adoption of tunnel type end-to-end encrypted transmission of video data, a set of high-definition video double-encryption transmission system is established so that video transmission under 4G network is safer and more reliable.
