双域架构设计在HD与4K制作共存阶段的实践应用

Practical Application of Dual Domain Architecture Design in Coexistence Stage of HD and 4K Production

为了解决高清与超高清共存制作阶段的问题,同时兼顾传统广电与IP化转型需求,贵州广播电视台超高清(4K)全媒体转播车通过双域架构设计,采用IP+基带的双链路双冗余系统设计,实现多种场景模式制作方式,既能满足现阶段传统广电制作习惯,也能适应4K以及将来8K的IP制作和升级需求。

In order to solve the problem of co-existence stage of HD and UHD production,while taking into account the needs of traditional broadcasting and IP transformation,UHD(4K)Omni-Media OB Van of Guizhou Radio and Television Station is designed through dual-domain architecture,adopting IP+baseband dual-link and dual-redundancy system design,and realizing production methods for a variety of scene modes.It not only meets the custom of traditional radio and television production at the present stage,but also meets the demand of IP production and upgrade needs of 4K and 8K in the future.
