基于云架构的4K超高清播出分发系统设计与实现

Design and Implementation of 4K UHD Broadcast and Distribution System Based on Cloud Architecture

为满足4K超高清节目的直播、转播和录播,本文提出了一种采用软件定义的超高清视频播出分发流程设计基于云架构的4K超高清播出分发系统的方案,可以用较低的延迟、更快捷的系统上线周期以及更低的系统建造成本在互联网上播出和分发超高清频道,系统的实现在一定程度上提升了当地超高清的整体发展水平。

In order to meet live broadcasting, rebroadcasting and recording of 4K UHD programs, this paper proposes a solution for designing a 4 K UHD broadcast and distribution system based on cloud architecture using a software-defined UHD video broadcast and distribution process, which can broadcast and distribute UHD channels on the Internet with lower delay, faster system launch cycle and lower system construction cost. The implementation of the system has improved overall development level of local UHD industry to a certain extent.
