标准摘要
[中文适用范围]： 描述了一种测量由于彩色信号中的随机噪声而导致的电视图像损伤的技术。应该认识到，可能存在其他机制，这些机制会引入似乎由随机噪声引起但无法测量的损伤。 [外文原描述]： Describes a technique for measuring the impairment of a TV picture due to random noise in a colour signal. The values which result from this measurement method make it possible to compare different video tape records, recording systems and video tapes for their random noise characteristics. Is intended for use with all IEC recognized video recording formats.
英文名称Measuring method for chrominance signal-to-random noise ratio for video tape recorders
