Taking a camera as an example for explanation: the camera is connected with the tested equipment through a network, the camera can transmit the collected audio and video data to the tested equipment through the network connection, and the electronic equipment capable of simultaneously playing the test video and the test audio is placed in front of the camera, so that the equipment head can collect the audio and video data and send the audio and video data to the tested equipment in real time, and the tested equipment plays the test video and the test audio based on the received audio and video data.
The method comprises the steps that a test video played by a tested device can be detected in different modes according to the content type of a target video frame, for example, if the target video frame is a video frame containing a preset special image (such as a circular image, a kitten or a puppy, etc.), image recognition is carried out on the test video played by the tested device to determine whether the video frame currently played by the tested device is the target video frame, if the video frame currently played contains the preset special image, the target video frame is detected, and if the video frame does not contain the preset special image, the target video frame is not detected; if the target video frame is a video frame with a specific color, the color sensor can be used for detecting the test video played by the tested equipment, if the currently played video frame is the video frame with the specific color, the target video frame is detected, and if the currently played video frame is not the video frame with the specific color, the target video frame is not detected; if the target video frame contains an optical signal image, a video frame of a preset brightness picture can be displayed, and the test video played by the tested device can be detected by the photosensitive sensor, that is, in an embodiment, the step of detecting the test video played by the tested device specifically includes:
