基于PQA600的电视节目制播全链路图像质量分析

Image Quality Analysis of TV Program Production and Broadcasting Based on PQA600

随着广播电视系统数字技术的飞速发展,电视系统数字信号的测试标准正在不断完善。当前,关于数字视频的研究集中在抖动、眼图等接口指标上,而评价方法决定了数字图像质量的评价质量。数字电视系统测量方法可以分为主观评价和客观评价两种方法。基于此,对于电视节目直播全链路的图像质量进行探讨,利用PQA600图像质量分析仪来分析全链路各个节点和端到端的电视节目图像质量,为提高电视节目全链路图像质量提供参考。

With the rapid development of digital technology in radio and television system, the test standard of digital signal in television system is constantly improving. The current research on digital video focuses on jitter, eye diagram and other interface indicators. The evaluation method determines the quality of digital image evaluation. The current digital television system measurement methods can be divided into subjective evaluation and objective evaluation methods. In this paper, the image quality of the whole link of live TV program is discussed, and the PQA600 image quality analyzer is used to analyze the image quality of TV programs at each node and end to end of the whole link, providing a reference for improving the image quality of TV programs in the whole link.
