摘要
随着IP技术的发展,有线电视前端由传统ASI架构转变为IP架构,信号分发系统由传统的SDH发展到以OTN为基础的第三代数字传输网,以满足新业务拓展的技术要求。本文通过介绍数字电视前端系统IP架构及OTN光传送网的优势,重点阐述基于IP架构的OTN节目分发系统的设计方案与播出安全保障措施。
With the development of IP technology, CATV front-end has changed from traditional ASI architecture to IP architecture, and signal distribution system has been developed from traditional SDH to the third generation digital transmission network based on OTN, which is to meet the technical requirements of new business expansion. By introducing the IP architecture of digital television front-end system and the advantages of OTN optical transmission network, this paper focuses on the design scheme of OTN program distribution system based on IP architecture and the safe broadcasting solution.
