The data sources may include HDMI, DVI, and usb, among others. On the other hand, the NFC reader 100 may detect the NFC key file in the object to be identified near the NFC reader in real time to generate an identification signal, so that the video processing module 300 may switch its output content according to the identification signal and the data source switching signal, so as to lock the data source, and only after the validity check is completed, allow the video processing module 300 to switch its output content.
Further optionally, the video processing module 300 is specifically configured to, when receiving the data source switching signal, switch the output content according to the target identity identification signal if the NFC reader 100 detects a target NFC key file that matches the video processing module 300. Specifically, when the data source is switched and the data source switching signal is generated, the NFC reader 100 detects whether the object to be identified carrying the target NFC key file is close, and only when the NFC reader 100 detects the target NFC key file and generates the target identity signal, the video processing module 300 is allowed to switch the output content according to the data source switching signal. Specifically, the video processing module 300 may be allowed to switch the output content if the target NFC key file is detected within a preset period of time before or after the data source switching signal is received.
