摘要： As the integration of telecommunications networks, cable TV networks and the Internet in China, the users who choose digital TVs to enjoy kinds of programs will become more and more. However, the security problem of the digital signal transmission process is still a crucial problem and hinders the rapid development of the application of digital TVs. A security system for the data transmission of digital TVs is proposed in this paper. The system consists of two parts: the attack detection platform and the graded protection and response emergency system for the whole network. By utilizing the composite digital watermarks, we offer a method for protection and detection in the system-wide. Furthermore, the system realizes the illegal content detection, protection, warning, location and handling in a real-time manner. Besides, the system achieves no blind spot detection and graded response and protection for the whole networks. Finally, we propose a test bed to simulate the proposed security1 system.
