Abstract

The invention relates to an automatic video measuring system based on LabVIEW and VideMASTER. The automatic video measuring system comprises a VideoMASTER video measuring instrument. The VideoMASTER video measuring instrument comprises a measuring computer mainframe, a plurality of data collecting cards and a displayer. Each data collecting card is provided with two video signal input ports. A LabVIEW-based video measuring platform is arranged in the measuring computer mainframe and comprises a hardware configuration module, a data collecting module, a data analysis module, a data display module, a data storge module, and a report generation module. The measuring system can automatically measure formats such as simulation composition, standard high definition components and VGA and formats such as digital HDMI and DVI.

Description

technical field [0001] The invention relates to the technical field of video signal measurement, in particular to a video automatic measurement system based on LabVIEW and VideoMASTER. Background technique [0002] With the development of TV technology, various types of video signals have appeared, mainly in the form of analog / digital, composite / component, standard definition / high definition, etc. The test of various types of video signal parameters is very important to the research and development of related video equipment. The development of video technology has promoted the improvement of video test level, and in turn, the enhancement of video test capability has created conditions for the update of video technology. [0003] With the development of digital technology, the vast majority of video signals are generated digitally. But this by no means means that analog measurements are no longer necessary. For example, one of the main output methods of a set-top box rece...
