Embodiment Construction

[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The present invention provides a method for video interface channel detection, referring to figure 1 , in the first embodiment, the video interface channel detection method includes:

[0038] Step S1, the signal generator sends the first image information to the current video interface of the image display device according to the video interface channel detection command sent by the debugging device, so that the image display device can be used as the current display image;

[0039] In this embodiment, there are many kinds of image display devices, which may be televisions, projectors, and the like. The operating system of the image display device may be an Android system or other smart operating systems. The signal generator has various video interfaces, such as audio and video interface, video graphics arra...

Abstract

The invention discloses a method and a system for video interface channel detection. The method for video interface channel detection includes following steps: a signal generator sends first image information to a current video interface of an image display device according to a video interface channel detection command sent by a debugging device so that the first image information is regarded as the current displayed image of the image display device; the debugging device sends a detection instruction to the image display device, wherein the detection instruction includes second image information corresponding to the first image information and an instruction for starting the detection; the image display device acquires the current displayed image according to the received detection instruction; and the image display device conducts image detection of the acquired images and the second image information and obtains a detection result. According to the method and the system, the efficiency for video interface channel detection of the image display device can be improved, and detection automation is realized.

Description

technical field [0001] The invention relates to the technical field of channel detection, in particular to a method and system for channel detection of a video interface. Background technique [0002] Image display devices, such as televisions and projectors, have more and more video interfaces, for example, televisions include Video Graphics Array (Video Graphics Array, VGA) interfaces, High Definition Multimedia Interface (High Definition Multimedia Interface, HDMI) interfaces, and the like. When the image display device is produced, each video interface must be tested to determine whether the hardware of each video port is normal. Usually, the detection of video interface channels is generally performed manually by workers to switch each signal source, and visually check whether the signals input through each video interface channel can be displayed normally. The efficiency of this detection method is low, and it is easy to have missed detection and cause the product to ...
