摘要
通过对有线电视可寻址收费管理系统的技术分析，得知不同厂家的射频开关方式系统和末端加扰方式系统的产品兼容需要其编码的调制频率、调制方式（如调频或调幅）相同，解码算法一致。在不具备兼容性的情况下，仍能通过并联共用方法应用不同厂家的产品。
Through the technical analysis of the CATV addressable charee managment system, it can be seen that the compatibility of the RF switching type and foo-end scramble type products produced by dtherent manufactories requlres the cooaination of their code modulation freqUency, medulation methods and decding algorithms respectively. In, the case of being incompatible, the thent manufactory products can be used together with the parallel cooperation scheme.
