基于反向代理的县级有线互动电视平台的时移回看改造

Transformation of Time-shifting and Looking-back Functions of County-level Cable Interactive TV Platform Based on Reverse Agent

江苏广电网络整合完成后,存在着省、市、县的前端、网络、终端技术标准不统一、技术体系不相同的问题,难以满足业务和技术快速发展的需要。本文针对县级互动电视平台“统一技术、统一业务和统一管理”的目标,提出基于Nginx反向代理的时移回看改造思路。付诸实践后,能在一定程度上实现统一播控平台,减少前端平台的投资规模,降低运维难度,缩减维护成本的效果。

After the completion of Jiangsu Radio and television network integration,there are some problems,such as inconsistent technical standards and different technical systems of front-end,network and terminal in provinces,cities and counties,which are difficult to meet the needs of the rapid development of business and technology.Aiming at the goal of “unified technology,unified business and unified management” of county-level interactive TV platform,this paper puts forward a time-shifted TV program transformation scheme based on Nginx(an open source,high-performance,highly reliable Web and reverse proxy server) reverse proxy,which can unify the broadcast control platform,reduce the investment scale of the frontend platform,reduce the difficulty of operation and maintenance,reduce maintenance costs,and improve the level of safe broadcast.
