手持式音视频产品性能测试方法的研究

Research in the performance measurement methods of handheld audio&video digital products

本文主要介绍了手持式音视频产品音频和视频性能测试的测试方法。音频的测试是将标准音频信号源输入到被测产品,通过音频测试仪进行测试;视频的测试是将标准视频源输入到被测产品后,采用主观与客观相结合的方法进行。通过加强对手持式音视频产品性能的测试,规范产品的检测方法,加强企业的质量意识,从而形成有效的质量控制方法。

The paper introduced the measurement methods of audio performance and video performance of the handheld digital products.The measurement of audio is to copy the standard audio signal source into the measured products and to test with the Audio Tester.The measurement of video is to copy the standard video source into the measured products and to measure in the method of combining subjective with objective.Through reinforcing the measurement of the handheld audiovideo digital products,we regulate the measurement methods of products and strengthen the quality sense of enterprises,generating an effectual method of quality controlling.
