摘要
本文以中央广播电视总台4K IP化移动外场视频系统的实践应用为背景,结合相关理论知识,详细研究论述了4K IP化视频系统中超高清HDR和高清SDR兼容的工作模式以及同步PTP的搭建和设置方式,并给出了目前系统运行中较为稳妥的解决方法,同时就未来4K IP化视频系统的搭建提出了相关建议。
Combined with relevant theoretical knowledge, this paper takes practical application of 4 K IP-based EFP video system of CMG as a background, discusses in detail compatible working mode of UHD HDR and HD SDR in 4 K IP-based video system as well as construction and setting of synchronous PTP methods.It gives a more stable solution to current system operation and at the same time, puts forward relevant suggestions for construction of 4 K IP-based video systems in the future.
