In this embodiment, in order to enable the first processing system, the first processing system may run the corresponding event, and the screen-on event is to be recovered, for example, a reminding event reported when some applications shielded by the Framework layer receive new notification messages is recovered, so that the notification messages of the applications can be received and processed in time when the first processing system is re-enabled; and meanwhile, restoring the hardware awakening source, restoring hardware which can awaken the electronic equipment when the first processing system enters the dormancy waiting mask, such as a power key of the electronic equipment, so as to restore awakening of the electronic equipment through the power key, thereby processing corresponding events through the first processing system.

When the connection state of the display interface and the cable is updated to be connected, the electronic equipment is controlled to be switched from the first processing system to the second processing system, namely the first processing system stops running, the electronic equipment enters a dormant state, and the second processing system is started to process the external video input signal. The first processing system stops running, and the running events related to the first processing system are suspended, and meanwhile the display control unit is powered on, so that the waiting time after the second processing system is started can be shortened, and the external video input signals can be processed for outputting as soon as possible. In specific implementation, the suspending of the operation event related to the first processing system includes a play event or a document processing event executed by the first processing system, the multimedia playing is stopped or the multimedia is saved, the document is closed and is not executed any more, after the running application is closed, the bright screen event in the first processing system is further shielded, for example, a reminding event when a new message notification of the application is reported is shielded through a framework layer, and the first processing system is prevented from being started to process when the new message notification of the application is reported; in the process that the first processing system enters the dormancy, a hardware awakening source of the electronic equipment is shielded, some hardware capable of awakening the electronic equipment is shielded, for example, a power key of the electronic equipment is shielded, the first processing system is prevented from being awakened through the power key of the electronic equipment, and finally a display screen of the electronic equipment is closed. At this time, the display screen of the electronic device cannot be turned on any more through the power key of the electronic device to wake up the first processing system, but the input/output path of the electronic device is configured through the display control unit and the turning on of the display screen of the electronic device is controlled.
Specifically, the relevant parameters of the device are first acquired by the display control unit, for example: the screen brightness, the volume, the battery capacity or the battery temperature are used for confirming the state of the electronic equipment, and controlling whether the first processing system enters the dormant state or not according to the working state of the display control unit. When the display control unit operates normally, the first processing system is controlled to enter a dormant state, the electronic equipment starts the operation of the second processing system, and at the moment, the electronic equipment is switched from the first processing system to the second processing system; when the display control unit is abnormal in operation, the first processing system is not controlled to enter the dormant state, further operation of a user is waited, for example, the connection state of the interface and the cable is checked or whether the cable has a problem is confirmed, and after the situation that no problem exists is confirmed, next operation is carried out according to the operating state of the display control unit.
After the electronic device is controlled to start the second processing system, when the display control unit works normally, parameters of the device are configured through the display control unit, for example, screen output and initial screen brightness of the device, a sound box inside the switch device and initial volume are configured, so that the electronic device can output image content corresponding to the external video input signal. Of course, in the process of operating the second processing system, the user can also adjust the parameters of the device through the display control unit, for example, when the brightness of the surroundings changes, the brightness of the display screen is adjusted up or down, or when the surroundings are noisy, the volume of the playing is adjusted up. In addition, the electronic equipment can acquire the working state of the display control unit according to a preset period, so that when the working state of the display control unit is disconnected or abnormal, the connection state of a cable or a related problem source can be checked in time, and the playing of the video content can be resumed in time.
Of course, the user may also disconnect the input signal from the display interface of the electronic device when the electronic device runs the second processing system, so that the electronic device may be switched from the running second processing system to the first processing system, i.e., deactivate the second processing system and enable the first processing system to process the relevant task or process for processing the electronic device. Wherein switching to the first processing system may comprise: the event corresponding to the first processing system is executed, and specifically, the event corresponding to the first processing system comprises the following steps: restoring response to the screen-lighting event, for example, restoring a reminding event reported when some applications shielded by the Framework layer receive new notification messages, so that the notification messages of the applications can be received and processed in time when the first processing system is restarted, and the electronic device is controlled to start the first processing system; meanwhile, the hardware awakening source is recovered, that is, the hardware capable of awakening the electronic device, such as a power key of the electronic device, which enters the sleep waiting mask at the first processing system is recovered, so as to recover to awaken the electronic device through the power key, and thus, the corresponding event is processed through the first processing system; the method comprises the steps of switching input and output paths of the electronic equipment, controlling the display screen to be opened through the first processing system, controlling the display screen to be lightened after an initialization process of the display screen is completed, wherein the first processing system normally operates at the moment, and can process related events, such as multimedia playing, related application program access, document processing and the like.
