摘要
本文介绍了一种全新交互电视架构,该架构基于HFC+IP网络,遵循国际国内规范,技术标准兼容性强且更为开放。采用智能判断规则,极大地发挥了现存HFC+IP网络的优势。系统特点:视频主要通过HFC网络传输,综合交互业务则通过IP网络传输。系统支持标清、高清、超高清和3D电视节目格式并能使点播、时移/回看等交互电视业务快速发展。新的交互电视架构为我们提供了一个系统、一个终端、两个平台,有助于广电网络运营商在三网融合背景下竞争力的提升。
The paper introduces a brand new interactive TV infrastructure which is using on HFC＋IP network.The project has satisfied compatible and open up for others.It precise follows the standard of international and china.Due to an intelligent determination principle,it has an outstanding performance and ability to play more talents that the system helps existing HFC＋IP network.System attractive traits： video are mainly transferring via HFC,the combination interactive service are using via IP.the system not only support SD,HD,SHV and 3D content types,but also provide nPVR,Time Shift function,etc.It promotes the development of interactive TV.The new interactive TV infrastructure supply to us one system,one terminal,two platforms and also increase competitive of broadcast television network operator during tri-network integration.
