The embodiment of the application provides a synchronous display method, and the synchronous display method is applied to a synchronous display system. Fig. 1 shows one of schematic diagrams of a synchronous display system provided in an embodiment of the present application, as shown in fig. 1, a first device 102 is connected to a second device 104, the first device 102 is a master device of the synchronous display system, the second device 104 is a slave device of the synchronous display system, and the number of the second device 104 is at least one, where the number of the second device 104 may be one or multiple.
Fig. 2 shows one of the flow diagrams of the synchronous display method provided in the embodiment of the present application, and as shown in fig. 2, the synchronous display method includes:
step 202, in the process that a first device sends a first signal to at least one second device, the first device receives a first request from a target device in the at least one second device;
the first signal is used for controlling synchronous display of first equipment and at least one second equipment, the first equipment is master equipment, and the second equipment is slave equipment.
It should be noted that the sender of the first signal is a master device in the synchronous display system, and the receiver of the first signal is a slave device in the synchronous display system, so that the display content of the master device is synchronously displayed in the slave device.
the second device is capable of sending a first request to the first device as the master device when the second device is the slave device, wherein the first request is used for the request of the slave device to become the master device.
The first device is operable to select whether or not to grant the request by operating the first device after receiving the first request from the second device in a case where the first device is a master device, and to transmit a second signal to the second device in a case where the first device grants the request, the second device that has received the second signal becomes a master device, and the first device that has transmitted the second signal becomes a slave device.
It is to be noted that, in a case where a first device (master device) receives first requests from a plurality of different second devices (slave devices) at the same time, a user can select, by the first device, a second device to be the master device by transmitting a second signal to a target device among the plurality of different second devices.
In step 206, in the case that the target device transmits the first signal to the remaining second devices and the first device of the at least one second device, the first device and the at least one second device display the first content on the same screen, and the first content is associated with the first signal.
It should be noted that after the target device receiving the second signal becomes the master device, the first device sending the second signal automatically becomes the slave device, and all devices in the synchronous display system are controlled by the target device to perform on-screen display.
In the embodiment of the application, the synchronous display system comprises a first device and a second device connected with the first device, and in the process that the first device serving as a master device controls a plurality of second devices serving as slave devices to synchronously display, the second devices serving as the slave devices can initiate a first request for becoming the master device. And under the condition that the first equipment agrees with the first request, the second signal is transmitted back to target equipment in the second equipment, so that the second equipment receiving the second signal becomes master equipment, the first equipment and the rest of the second equipment are slave equipment, and the first equipment and the rest of the second equipment are controlled by the target equipment to perform synchronous display.
Specifically, the master device in the synchronous display system is a device for controlling the synchronous display system, that is, the content displayed by each device in the synchronous display system is controlled and adjusted by the master device. The slave device is a device controlled by the master device in the synchronous display system. In the synchronous display system, during operation, the master device controls the plurality of slave devices to synchronously display the same display content with the master device, the slave devices can send a first request to the master device at any time to request to become the master device, and when the current master device agrees to the first request, the slave device sending the first request becomes the master device and the master device receiving the first request becomes the slave device.
The synchronous display system is exemplarily applied to a video conference, during which a master device in the synchronous display system controls participating electronic devices to perform synchronous display, and the content of the synchronous display is controlled by the master device, wherein the synchronous display system can be selected as not only the display content of the master device but also the display content of a slave device. In the synchronous display process, under the condition that a user of the slave equipment in the synchronous display system needs to display contents for other conference participants, the user of the slave equipment sends a first request to the master equipment, and the user of the master equipment controls whether the master equipment agrees with the first request according to actual requirements. In the event that the first request is granted, the slave device that sent the first request becomes the master device to control the synchronized display content of the electronic devices participating in the video conference.
In the related art, the master device of the synchronous display system can only perform one-way synchronization on the slave devices, such as the master device performing screen sharing on the slave devices, or the master device performing remote control on the slave devices. Under the condition that the reverse synchronization requirement exists in the process of unidirectional synchronization of the master device to the slave device, synchronous connection needs to be reestablished, and the operation is complex.
In the embodiment of the application, in the process that the first device serving as the master device controls the second device serving as the slave device to perform synchronous display, the second device serving as the slave device can send a first request for becoming the master device to the first device, and the second device sending the first request becomes the master device under the condition that the first device agrees with the first request, so that the master device identity and the slave device identity of the connected first device and second device can be switched at any time, and under the condition that the slave device has a requirement for performing reverse synchronization on the master device, synchronous connection does not need to be reestablished, thereby simplifying the operation steps of a user.

under the condition that the first device sends a first signal comprising first display content to the plurality of second devices, the first device and the second devices synchronously display the current first display content of the first device, and the first display content of the first device is changed, so that the display contents of the first device and the plurality of second devices in the synchronous display system are changed.
Under the condition that the first device sends a first signal comprising second display content to the plurality of second devices, the first device and the second devices synchronously display the current second display content of the second devices, and the second display content of the second devices changes, so that the display contents of the first device and the plurality of second devices in the synchronous display system change.
In the case where the first device transmits the first signal including the first display content and the second display content to the plurality of second devices, the first device and the second devices synchronously display the first display content and the second display content, that is, the first device and the second devices synchronously display the entire display contents of both.

Namely, the master device and the slave device in the synchronous display system synchronously display the first content in the master device and the second content in the slave device.
