摘要
随着《超高清视频产业发展行动计划(2019-2022年)》的发布与实施,为进一步实施“4K先行、兼顾8K”的行业发展战略,提升超高清电视播出系统的建设运行效率,有必要对12G SDI技术进行深入探究。文章基于12G SDI技术设计了超高清电视播出系统架构,分析了系统功能配置及实现情况,并从信号源接入转换、视频播放存储、播出控制、延时播出、高标清同播等方面展开了论述,希望能够为超高清电视播出系统的设计开发提供一些借鉴。
With the release and implementation of the"Action Plan for the Development of Ultra High Definition Video Industry(2019-2022)",it is necessary to conduct in-depth exploration of 12G SDI technology in order to further implement the industry development strategy of"4K first,considering 8K",and improve the construction and operation efficiency of ultra high definition television broadcasting systems.The article designs an ultra high definition television broadcasting system architecture based on 12G SDI technology,analyzes the system's functional configuration and implementation,and discusses aspects such as signal source access conversion,video playback storage,broadcasting control,delayed broadcasting,and high standard definition simultaneous broadcasting.It is hoped that this can provide some reference for the design and development of ultra high definition television broadcasting systems.
