摘　　要：CATV自动寻址与收视控制信息系统将通讯、计算机、软件、自动化控制等理论结合起来,能够对收视末端进行自动寻址和控制收视状态。本系统通过主控软件系统把收视用户交费信息以及地址信息编码后,生成数字信号发送到FSK数据加密调制器,再由FSK数据加密调制器发送到CATV前端混合器,由CATV前端混合器将编码数字信号和电视信号混合后传输到智能寻址集中分配器,最后由智能寻址集中分配器控制用户收视状态。The system of automatic addressing and control of televiewing in CATV integrates with the theories about communication, software, automatization cortrol, etc, in order to automatically search for CATV terminal addressing and controlling the audience state. This system first codes the information of the fee and address. After turning the code into digital signal, it is sent to the FSK data encrypt modulator, and also sent to the CATV synthesizer by this modulator. The coding digital signal and the television signal are commixed by the CATV synthesizer, and the commixed signal is again sent to the automatic addressing concentrated distributive organ. Lastly, the audience televiewing state is controlled.
