Embodiment Construction

[0014] The method of the invention can be used to test whether the image storage medium played by the computer is normal, especially for the playback test of the VCD disk and the playback test of the DVD disk. figure 1 and figure 2 The schematic diagrams of the principles of VCD and DVD playback tests using the method of the present invention are given respectively.

[0015] Method of the present invention can basically be summarized as:

[0016] Make VCD (DVD) samples on the prototype machine, that is, call DirectX to play VCD (DVD) discs and capture each frame of image and save it as a sample file;

[0017] Play the VCD (DVD) disc on the machine to be tested, and obtain the number of lost frames, frame transmission interval, frame delay, and average playback rate (frame / second) by calling the function in DirectX, and compare it with the defined standard to judge whether it is in the playback process Frame loss, frame transmission interval is too large, frame delay is too ...

Abstract

The invention discloses method to detect storage medium for displayed image in computer is whether normal, which is to use same image storage medium sample disk on window OS supported DirectX8.0 or higher version. Include samples on sample computer, intercept every frame image and store to sample document; display image storage medium on computer waiting for detection, intercept and store image to memory zone; compare the every image in memory zone with corresponding images in standard sample document, if images are almost consistent, the detection succeeds, or failure. The invention can detect whether storage medium is wrong in large scale, decrease workload of workers, cut detection time and decrease its cost; it can be expanded according to real need and fit to multiple media. The invention can also detect read disk capability of CD driver and data transmission rate.

Description

technical field [0001] The invention relates to a method for testing whether a computer plays an image storage medium normally, in particular to a method for batch testing whether a computer optical drive plays VCD and DVD discs normally, and belongs to the field of computer and information technology. Background technique [0002] With the rapid development of computer technology, optical drive has become a must-have device for every computer, especially when the computer is sold to end users, it is often used to play image storage media, such as various VCD discs or DVDs Therefore, it is necessary to test the computer for playing VCD (DVD) after the computer system is assembled. The simplest method is to directly open the media player or DVD player of Windows itself, and directly play the image storage medium in the optical drive, such as VCD or DVD disc, and at the same time, the tester visually inspects the content played in the media player However, the playback speed ...
