Problems solved by technology

In this way, the whole test process must be watched by someone, which is a waste of manpower
In addition, since human evaluation is subjective and there is no uniform performance evaluation standard, it is very likely that the evaluation will be wrong.

Embodiment Construction

[0030] like figure 1 As shown, the test system 99 includes a video playback device 100 and a test device 200 . The testing apparatus 200 is used for testing the playback performance of the video playback apparatus 100 . The video playing device 100 is used for playing a specific video segment for testing, and generates a start signal when the specific video segment starts to be played. Usually the above-mentioned specific video segment has video characteristics corresponding to the playback performance to be tested. For example, if the smoothness of the video playback device 100 needs to be tested, each adjacent two images in the corresponding specific video segment have continuity.

[0031] The testing device 200 includes an imaging element 210 , a first storage unit 220 , a decomposition unit 230 , a scaling unit 240 , an analysis unit 250 , a second storage unit 260 , a comparison unit 270 and an output unit 280 .

[0032] The camera element 210 is used to capture the vi...

Abstract

The invention relates to a testing apparatus, which is used for testing a playing performance of a video playing device. The video playing device is used for playing a specific video episode used for testing; and when the playing is started, a starting signal is generated. The testing apparatus comprises a shooting element, a decomposition unit, an analysis unit, a comparison unit and an output unit. The shooting element responds to the starting signal and shoots the video played by the video playing device. The decomposition unit decomposes the shot video into an image sequence according to a playing speed of the video playing device. The analysis unit selects images according to a predetermined rule and makes comparison on data information of the selected images to analyze a playing characteristic parameter of the video playing device. The comparison unit determines an error between the playing characteristic parameter of the video playing device and a video characteristic parameter of the specific video episode, wherein the playing characteristic parameter is obtained by the analysis; and according to the error, a playing performance of the video playing device is determined. And the output unit outputs the playing performance of the video playing device. In addition, the invention also provides a testing method.

Description

technical field [0001] The invention relates to a testing system, in particular to a device and a testing method for testing the playback performance of a video playback device. Background technique [0002] Usually, when developing a video playback device, the playback performance of the video playback device is tested. The existing test method is to evaluate the playback performance of the video playback device by watching the video with human eyes. In this way, someone must watch the entire testing process, which is a waste of manpower. In addition, since human evaluation is relatively subjective and there is no uniform performance evaluation standard, it is likely that the evaluation will be wrong. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide a test device which is convenient for testing the playback performance of the video playback device. [0004] In addition, it is also necessary to provide a test method which is convenient for t...
