由于4K超高清(Ultra High Definition,UHD)和高动态范围(High Dynamic Range,HDR)技术的快速发展及其在广播电视制播中的广泛应用,传统广播电视台急需进行技术升级和系统优化.在这一背景下,4K超高清融媒体转播车视频系统的设计与优化尤为关键.视频系统不仅需要处理更高分辨率的视频信号,而且必须兼顾HDR内容的传输与处理,还要保持与现有制播流程的兼容性.基于此,系统地对 4K超高清融媒体转播车视频系统进行设计优化,包括对摄像机、切换台以及数据交换系统的优化设计,旨在提升视频系统的整体性能,确保高质量的直播信号传输和处理,同时增强系统的灵活性和未来兼容性,为观众提供更加出色的视听体验.
Design and Optimization of 4K Ultra High Definition Video System for Broadcasting and Television Stations
Due to the rapid development of 4K Ultra High Definition(UHD)and High Dynamic Range(HDR)technologies and their wide application in broadcasting,traditional broadcasting stations are in urgent need of technology upgrading and system optimization.In this context,the design and optimization of 4K UHD video system is particularly critical.The video system not only needs to handle the higher resolution video signal,but also must take into account the transmission and processing of HDR content,and maintain the compatibility with the existing production and broadcast process.Based on this,the design and optimization of the video system of the 4K UHD fusion media broadcasting vehicle were systematically carried out,including the optimization design of the camera,the optimization design of the switching station and the optimization design of the data exchange system,aiming to improve the overall performance of the video system,ensure high-quality live signal transmission and processing,and enhance the flexibility and future compatibility of the system.To provide the audience with a better audio-visual experience.
