有条件接入系统中的用户基础事实报告和受保护内容传送 – 要求 |
ITU-T J.1036建议书旨在解决与条件访问系统(CAS)相关的两大问题,即低报漏报用户数量和内容盗版导致广播机构、内容提供商和政府收入损失。大多数国家已在有线电视、直接到户(DTH)、互联网协议电视(IPTV)和空中前端(HITS)等分发平台实施了数字可寻址系统(DAS),DAS使签约用户能够选择频道和套餐。条件访问系统(CAS)和签约用户管理系统(SMS)是DAS环境不可或缺的组成部分。CAS负责对内容进行加密并以安全和加密的方式仅向授权用户传送,而SMS则负责处理用户管理功能。服务质量取决于分发平台所有者(DPO)部署的CAS和SMS系统。 由于内容提供商和广播公司无法控制CAS和SMS,因为它们部署在DPO端,他们经常抱怨因各种不当行为(如低报漏报用户数量、向未经授权的用户分发频道以及内容盗版)造成的收入损失。因此,有必要为CAS系统制定基准,规定以功能要求为重点的技术规范,以确保如实报告用户数量并向授权用户进行受保护的内容传送。创建一个防止部署低于标准的CAS的框架,对因此类系统的脆弱性而造成的潜在威胁和收入损失进行预防性控制,从而带来经济效益,提高服务质量,并改善最终消费者的体验。因此,此建议书详细阐述了CAS的各种功能要求,例如日志要求、报告要求、数据库要求、安全要求、服务要求等。在CAS性能方面遵守这些要求将解决上述关切。 |
