本文件规定了互联网协议电视（IPTV）安全接口规范的一个潜在示例。A-POD规范并不是IIF标准或IPTV中唯一可能实现的可分离安全元素（SSE）。本文件中规定的解决方案实现了IPTV的物理可分离安全解决方案，该解决方案与现有的单向和多流CableCARD？标准协调并向后兼容。 因此，本标准中定义的解决方案可能不是实现IPTV可分离安全性的最有效方法。本文档定义了与服务/网络提供商的网络技术无关的IP流。请注意，本规范旨在与混合网络和有线电视系统兼容，因此可能与所有现有的IPTV部署不兼容。

This document specifies one potential example of an Internet Protocol Television (IPTV) security interface specification. The A-POD specification is not the only possible implementation of a Separable Security Element (SSE) within the IIF standards, or for IPTV in general. The solution specified in this document achieves a physically separable security solution for IPTV that is harmonized with and backwards compatible to the existing unidirectional and multi-stream, CableCARD¿ standards. As such, the solutions defined in this standard may not be the most efficient method for accomplishing IPTV separable security. This document defines the IP flows that are agnostic to the network technology of the service/network provider. Note that this specification was designed for compatibility with hybrid networks and cable systems, and therefore may not be compatible with all existing deployments of IPTV.
