Embodiment

[0026] This embodiment provides a novel PDM audio and video test system, such as figure 1 As shown, including the interconnected PDM audio and video test device, test equipment platform and audio and video module, the PDM audio and video test device is used to analyze each audio measurement index of the audio and video module and simultaneously output each audio and video image. The test equipment platform is used to sample and analyze the data measured by the PDM audio and video test device, integrate the PDM audio measurement index and video measurement image data, and compare with the specified standard value. The test equipment platform analyzes and compares the difference between the audio and video indicators and the standard value through the VB assembly tool software, and completes the audio and video function detection work.

[0027] It can be, but is not limited to, the test equipment platform and the audio and video module are connected through two sets of SPK artif...

Abstract

The invention discloses a novel PDM audio and video test system. The system comprises a PDM audio and video testing device, a test equipment platform and an audio-video module which are connected witheach other. The PDM audio and video test device is used for analyzing each audio measurement index of the audio and video module and outputting various formats of data of a video image at the same time; and the test equipment platform is used for sampling and analyzing the data measured by the PDM audio and video test device, integrating the PDM audio measurement index and the video measurement image data and comparing the PDM audio measurement index and the video measurement image data with specified standard values. By adopting the technical scheme, the test is accurate and reliable, the measurement time is greatly shortened, the production efficiency is improved, and the manpower resources are saved.

Description

technical field [0001] The invention relates to the field of audio and video testing, in particular to a novel PDM audio and video testing system and method. Background technique [0002] At present, the existing audio and video modules are equipped with a relatively complex test system, usually using two to three test tooling positions, one is responsible for testing the video module function; the other is responsible for the PDM audio module testing function; the test data results also need to pass complex Connect to merge data. [0003] Disadvantages of the existing PDM audio and video test system: [0004] 1) It takes two test stations to complete the PDM audio and video test, the test efficiency is low, and the labor cost is increased; [0005] 2) The test module is easily damaged by high voltage (static electricity and ESD) when it passes through multiple test stations; [0006] 3) The audio sensor used in the audio and video test system is not consistent, which is ...
