摘要

电视制作播出（以下简称制播）呈现系统经历了从黑白到彩色、从模拟到数字的演进历程，目前正处于从高标清向超高清快速发展的阶段.传统电视高清基带系统信号传输速率仅为1.5 Gbps，无法承载4K/8K超高清信号（48 Gbps@8K，12 Gbps@4K），且高清电视亮度动态范围只有10

，而人眼在无瞳孔调节时可视范围为10

，因此超高清电视应按照人眼识别的能力，将亮度动态范围提升至10

.本文针对超高清无压缩跨域多址互联网协议（Internet Protocol，IP）交换和高动态范围（High Dynamic Range，HDR）制播呈现等技术实现的难题，围绕全台4K/8K演播室、总控、播出及收录等超高清系统全链路的建设情况，全面介绍4K/8K超高清电视的制播呈现系统及关键技术，重点阐述系统超高清IP信号交换、8K超高清

视频成像和图像处理、视频智能增强、扩展现实（eXtended Reality，XR）虚实融合制作、三维菁彩声、异构网络视音频同步传输和4K/8K超高清终端显示等技术创新点，以及超高清高动态特性的采集、制作、播出和呈现全流程节目制播能力.

Abstract

The television production and presentation system has undergone an evolution from black and white to color

and from analog to digital. Currently

it is in a stage of rapid development from high definition (HD) to ultra-high definition (UHD). The signal transmission rate of the traditional HD baseband system is only 1.5 Gbps

which is unable to carry 4K/8K UHD signals (48 Gbps@8K

12 Gbps@4K). Moreover

the luminance dynamic range of HD television is only 10

while the human eye's visible range without pupil adjustment is 10

. Therefore

UHD television should enhance the luminance dynamic range to 10

in accordance with the human eye's recognition ability. Focusing on the technical challenges such as uncompressed cross-domain multi-address Internet Protocol (IP) switching and high dynamic range (HDR) production and presentation for UHD

this paper comprehensively introduces the UHD television production and presentation system and key technologies

with a particular emphasis on the innovative points of UHD IP signal switching

8K UHD video imaging and image processing

video intelligent enhancement

extended reality (XR) virtual-real fusion production

Audio Vivid

heterogeneous network audio-video synchronization transmission

and 4K/8K UHD terminal display

as well as the full-process program production and presentation capabilities of UHD high dynamic characteristics.
