作为在有线电视版权保护中起到关键作用的条件接收算法软件CAS,在给用户提供优质服务的同时,也为合法的内容版权保驾护航,只有健康的“三网融合”生态体系构建起来,才能看到更好电视,数字电视之花才会更加艳丽多姿。不过有线电视自数字化改造以来就受到各种技术条件和市场环境的影响,未对CAS条件接收规范进行统一,源自欧洲DVB-C的数字电视CA加密体系主导了各地运营商的技术架构,由各CA公司以非国家标准协议的方式控制主要市场格局。据相关报道称:“这种以各自CA的私有封闭技术标准的加密系统将全国大大小小的广电运营商分割得支离破碎,在这种情况下,即使一些省网完成了整合,也会让整合后的省级广电运营商离”统一规划,统一经营“的目标相距甚远,大幅度增加了运营成本。如果连省内的规范都不能统一,国家有线电视网络公司即使成立,也可能沦为一个空架子。”
As a conditional access algorithm software CAS that plays a key role in the copyright protection of cable television, while providing users with excellent services, it also escorts legitimate copyright of the content. Only the healthy “triple play” ecosystem is built In order to see better television, digital television will be more colorful and colorful flowers. However, cable TV has been affected by various technical conditions and market environment since its digitalization. It has not unified the CAS acceptance criteria. The digital television CA encryption system originated from DVB-C in Europe dominates the technical structure of operators. Each CA company controls the main market pattern in a non-state standard agreement. According to the relevant report, “This kind of encryption system, which is based on the private closed technology standard of its own CA, has fragmented large and small radio and television operators all over the country. In this case, even if some provincial networks have completed the integration, After the integration of the provincial radio and television operators from the ”unified planning, unified management “ goal far apart, a substantial increase in operating costs.If even the norms can not be unified within the province, even if the national cable network companies set up, but also May be reduced to an empty shelf. ”
