The accuracy of the detection further improves the user experience.

或者，在图1所示实施例中的信号参数可以是高宽比信息，显示设备可以从接收到的视频信号中获取视频信号的高宽比信息，即图1所述步骤101具体可以为：Alternatively, the signal parameter in the embodiment shown in FIG. 1 may be the aspect ratio information, and the display device may obtain the aspect ratio information of the video signal from the received video signal, that is, the step 101 described in FIG. 1 may specifically be:

在接收到外部输入设备通过HDMI输入的视频信号之后，显示设备检测视频信号的高宽比信息是否与已配置的HDMI版本的EDID信息中的高宽比信息一致。After receiving the video signal input by the external input device through the HDMI, the display device detects whether the aspect ratio information of the video signal coincides with the aspect ratio information in the EDID information of the configured HDMI version.

其中，已配置的HDMI版本的EDID信息中包含高宽比信息，例如：若已配置HDMI2.0版本，则其EDID信息中的高宽比信息为21:9。The EDID information of the configured HDMI version includes aspect ratio information. For example, if the HDMI2.0 version is configured, the aspect ratio information in the EDID information is 21:9.

在本发明实施例中，显示设备可以检测接收到的视频信号的高宽比信息是否与已配置的HDMI版本的EDID信息中的高宽比信息一致，若不一致，则表示接收到的视频信号为异常信号，显示设备切换HDMI版本，使得可以由显示设备识别视频信号的异常及完成HDMI版本的切换，而不需要用户在发现画面异常之后通过手动操作切换HDMI版本，适用性好且有效改善用户体验。In the embodiment of the present invention, the display device may detect whether the aspect ratio information of the received video signal is consistent with the aspect ratio information in the EDID information of the configured HDMI version. If not, the received video signal is Abnormal signal, the display device switches the HDMI version, so that the display device can recognize the abnormality of the video signal and complete the switching of the HDMI version, without the user switching the HDMI version by manual operation after finding the abnormality of the screen, the applicability is good and the user experience is effectively improved. .

进一步地，信号参数在除了包含上述的高宽比信息之外，还可以包含信号类型，该信号用于在检测到视频信号的信号参数中的高宽比信息与已配置的HDMI版本的EDID信息中的高宽比信息一致的情况下，进一步确定视频信号是否异常。Further, the signal parameter may further include a signal type for detecting the aspect ratio information in the signal parameter of the video signal and the EDID information of the configured HDMI version in addition to the aspect ratio information described above. In the case where the aspect ratio information in the middle is consistent, it is further determined whether the video signal is abnormal.

具体的，显示设备在检测到视频信号的信号参数中的高宽比信息与已配置的HDMI版本的EDID信息中的高宽比信息一致的情况下，检测视频信号的信号参数中的信号类型是否与已配置的HDMI版本的EDID信息中的信号类型一致。Specifically, the display device detects whether the signal type in the signal parameter of the video signal is consistent if the aspect ratio information in the signal parameter of the detected video signal is consistent with the aspect ratio information in the EDID information of the configured HDMI version. Consistent with the signal type in the EDID information of the configured HDMI version.

若检测到视频信号的信号参数中的信号类型与已配置的HDMI版本的EDID信息中的信号类型一致，则确定该视频信号为正常信号，不需要进行HDMI版本的切换。If it is detected that the signal type in the signal parameter of the video signal is consistent with the signal type in the EDID information of the configured HDMI version, it is determined that the video signal is a normal signal, and the HDMI version is not required to be switched.

若检测到视频信号的信号参数中的信号类型与已配置的HDMI版本的EDID信息中的信号类型一致，则确定该视频信号为异常信号，显示设备将切换HDMI版本。If it is detected that the signal type in the signal parameter of the video signal is consistent with the signal type in the EDID information of the configured HDMI version, it is determined that the video signal is an abnormal signal, and the display device will switch the HDMI version.

在本发明实施例中，在检测到视频信号的信号参数中的高宽比信息与已配置的HDMI版本的EDID信息中的高宽比信息一致的情况下，将利用信号参数中的信号类型对视频信号进行进一步的检测，能够有效提高视频信号检测的准确率，进一步改善用户体验。In the embodiment of the present invention, in the case that the aspect ratio information in the signal parameter of the detected video signal is consistent with the aspect ratio information in the EDID information of the configured HDMI version, the signal type pair in the signal parameter is utilized.
