It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

The method is applied to a scene of performing function test on the audio and video interface. As shown in fig. 1, the technical solution provided by the embodiment of the present invention specifically includes:
and S110, acquiring original data input by the audio and video interface, and analyzing the original data to obtain analyzed data.
The analysis data comprises at least one analysis image and analysis sound corresponding to the analysis image.
Specifically, the audio/video interface may be a transmission interface of digital high-definition audio/video stream. The audio/video Interface may be a High Definition Multimedia Interface (HDMI), a dp (display port) Interface, or another Interface. The HDMI interface is adopted as a line transmission path by display equipment such as a television, a projector and the like, a set-top box used at home and a well-known game host platform. DisplayPort can provide a number of different connection solutions for PCs, monitors, display panels, projectors, and high-resolution content applications. The scheme can test the audio and video interface function of the equipment integrated with the audio and video interface so as to test whether the data output by the audio and video interface of the equipment is correct or not. According to the scheme, the original data output by the audio and video interface of the equipment can be obtained, and the original data is analyzed to obtain the analyzed data. The original data is serial data, including audio data and video data. The analysis data is parallel data and comprises at least one analysis image obtained by analyzing video data in the original data and analysis sound corresponding to the analysis image obtained by analyzing audio data in the original data. The format of the analysis image may be RGB format, and the format of the analysis image may also be YCbCr format. The form of the analysis sound may be stereo, mono, left, right, surround 4, or surround 8. The method of analyzing the original data to obtain the analyzed data may refer to the related art.
And S120, if the target image matched with the first standard image of the standard data exists in the analysis data, determining the target data meeting the test condition in the analysis data.

The standard data can be obtained by analyzing data output by equipment with a normal audio/video interface function, and the standard data can also be obtained in other forms.
Wherein, the scheme starts to execute the test action only when the image synchronization signal is received. Specifically, the image synchronization signal indicates the start of one frame of image. Since the raw data is continuously input, the analysis data obtained by analyzing the raw data is also continuous. In the process of continuously inputting the analysis data, the beginning of each frame of analysis picture corresponds to an image synchronization signal. According to the scheme, if the target image matched with the first standard image of the standard data exists in the analysis data, for example, the consistency rate of the target image and the first standard image is more than 95%, the analysis data corresponding to the standard data is found, and the target data meeting the test condition in the analysis data can be determined.

Specifically, the comparison result may be a numerical value, which is a similarity value between the target data and the standard data, or a difference value between the target data and the standard data. The comparison result may be consistent or inconsistent, for example, whether the format of the target image is consistent with the format of the corresponding standard image, and whether the format of the target sound is consistent with the format of the corresponding standard sound. According to the scheme, each target image in the target data can be compared with each standard image in the standard data respectively to obtain the comparison result of each target image, and then the comparison result of the target data is obtained. According to the scheme, each target image in the target data can be compared with each standard image in the standard data, the sound corresponding to each target image is compared with the sound corresponding to each standard image in the standard data, the comparison result of each target image and each target sound is obtained, and the comparison result of the target data is further obtained.

The method and the device can determine the result of the audio/video interface function test according to the comparison result of the target data and the standard data and the preset constraint condition, such as the number of tested frames of images, the total image consistency rate of the target data and the standard data, the total sound consistency rate of the target data and the standard data, and the like.

And by analogy, comparison results of all the analysis images in the target data are obtained.
Therefore, the comparison result is obtained by comparing each target image in the target data with each standard image. The video function test of the audio and video output interface can be realized, the test efficiency can be improved, the test cost is saved, and the test space is saved.
In another possible embodiment, optionally, comparing the target data with the standard data to obtain a comparison result, including: and comparing each target image in the target data with each standard image respectively, and comparing the target sound corresponding to each target image with the standard sound corresponding to each standard image to obtain a comparison result.

Respectively acquiring the sound of the two frames of images at 0.02s, namely respectively acquiring the analytic sound and the standard sound when 0.02s, comparing the similarity of the two sounds, and judging whether the sound types are the same, for example, whether the sound types are all monophonic, stereophonic, left channel and right channel; in the case of surround sound, it is not all 4 surround sound, or it is not all 8 surround sound. It is possible to judge whether or not the 0.02s analyzed sound matches the standard sound recorded before and the content of the change in the 0.02s sound. And by analogy, obtaining a comparison result of the target data.
Therefore, the comparison result is obtained by comparing each target image in the target data with each standard image respectively and comparing the target sound corresponding to each target image with the standard sound corresponding to each standard image. The audio and video function test of the audio and video output interface can be realized, the test efficiency can be improved, the test cost is saved, and the test space is saved.
