摘　　要：随着4K超高清摄像机的普及,以及千兆、万兆、40Gb局域网的建设,电视台的播出控制系统将向4K超高清播出应用迈进。由于4K码率较高,在播出系统中应用基带信号进行播出的可能性不大,所以本文将主要分析基于IP流信号的4K播出系统应用及主要面临的问题。With the slow popularization of 4K ultra-HD cameras,and after the construction of a thousand trillion,mega,and 40Gb local area networks,the broadcasting control system in a TV station is moving to the 4K ultra-HD broadcasting application.Because 4K bit rate is higher,it is almost impossible to transmit the baseband signal in the broadcasting system.This paper analyzes the main problems in the 4K broadcasting system based on IP signal.
