IPTV行业从早期的私有系统逐步发展到如今有规范标准可遵循,为行业的健康发展提供了巨大帮助,同时由于多种标准体系的存在,也为行业人士在标准取舍过程中增加了很多困惑和挑战。金罗军博士继上期对基于NGN的下一代IPTV的几大标准体系进行介绍后,本期重点针对ATIS-IIF制定的IPTV高层次系统架构,分别从逻辑域及其相互间的接口、公共的分层组件和消费者家庭网络等几个方面进行了介绍,希望能够帮助国内行业人士了解这一标准体系。如果您对此有何建议和想法,欢迎发邮件至cui_muli@ccw.com.cn或者john.king.ca@gmail.com。
The gradual development of the IPTV industry from the early private systems to the current standard specifications can be followed, which has provided tremendous help to the healthy development of the industry. At the same time, due to the existence of a variety of standard systems, IPTV industry has also added a lot of confusion to the standard trade-off process challenge. Following the introduction of several major standards systems for NGN-based next-generation IPTV in the previous period, this issue focuses on the IPTV high-level system architecture developed by ATIS-IIF, starting from the logical domains and their inter-interface, public Layered components and consumer home networks were introduced in several aspects, hoping to help domestic industry professionals to understand the standard system.
