Embodiment 1

[0038] Such as figure 1 As shown, the system for testing digital audio and video interfaces provided by this embodiment includes a device under test, a test terminal, a camera, a recording device and a USB HUB5. Wherein, the recording device is a USB Microphone 4 , the camera device is a USB WebCam 3 , the equipment to be tested is a notebook computer 1 , and the test terminal is a display 2 .

[0039] It should be noted that the device under test in the system for testing the digital audio-video interface provided by the present invention is not limited to a notebook computer, and actually the device under test may be various devices including a digital audio-video interface. In addition to the notebook computer in this embodiment, it can also be other devices including digital audio and video interfaces, such as smart phones, tablet computers, or desktop computers.

[0040] The digital audio-video interface of the notebook computer 1 is electrically connected with the corre...

Embodiment 2

[0046] Such as figure 2 As shown, the method for testing the digital audio-video interface provided in this embodiment is based on the system implementation for testing the digital audio-video interface provided in Embodiment 1. The method includes the following steps:

[0047] Step 101, electrically connect the digitized audio and video interface of the notebook computer 1 to the corresponding interface of the display 2, connect the USB interface of the USB Microphone4 to any downlink interface of the USB HUB5, and connect the USB interface of the USB WebCam3 to the For any other downlink interface of the USB HUB5, the uplink interface of the USB HUB5 is connected to a USB interface of the notebook computer 1, and the audio interface of the USB Microphone4 is electrically connected to the audio interface of the display 2;

[0048] Step 102, after the notebook computer 1 detects that the display 2 above its digital audio-video interface is connected, it controls the display 2...

Abstract

The invention discloses a method and system for testing a digital audio-video interface. The method comprises the following steps: S1, a digital audio-video interface of to-be-tested equipment is electrically with a testing terminal, and a camera device is electrically connected with the to-be-tested equipment; S2, the to-be-tested equipment controls the testing terminal to display a testing picture through the digital audio-video interface; S3, the to-be-tested equipment controls the camera device to shoot the testing picture displayed by the testing terminal to obtain to-be-analyzed imagingdata; and S4, the to-be-tested equipment analyzes the to-be-analyzed imaging data so as to determine whether the testing picture displayed by the testing terminal is normal. Through the method and system for testing the digital audio-video interface provided by the invention, an operator is unnecessary to check whether the video function is normal through visual inspection, the camera device can automatically accomplish the testing on the video function of the digital audio-video interface through once access, the manpower cost can be reduced, and the automatic testing degree is improved.

Description

technical field [0001] The invention belongs to the technical field of digital audio and video interface testing of electronic equipment, and in particular relates to a method and system for testing a digital audio and video interface. Background technique [0002] Many of the existing electronic devices include digital audio and video interfaces such as HDMI (High Definition Multimedia Interface) or DisplayPort (a high-definition digital display interface). Testing of audio and video functionality. Existing methods usually use the operator to visually check whether the external test terminal displays normally, and listen to the sound with the ear to see if it is normal; in addition, there is another method to judge through the external circuit board. In the above two methods, there are problems of low test stability, high manpower cost and low degree of automation. Contents of the invention [0003] The technical problem to be solved by the present invention is to overc...
