When a plurality of projection devices receive the broadcast signal, the communication connection with the electronic device can be established according to the broadcast signal.
Step S102: the electronic equipment receives equipment information and first screen projection parameters returned by at least one projection equipment according to the broadcast signals.
After receiving the broadcast signal sent by the electronic device, the projection device feeds back device information of the projection device and first screen projection parameters to the electronic device, wherein the device information may include a device identifier, and the first screen projection parameters may include one or more of contrast, brightness, resolution, network signal strength of the projection device, parameters representing whether the projection device has the capability of outputting sound, and parameters representing that multiple electronic device projections can be received for multi-split projection.
Step S103: and the electronic equipment determines second screen projection parameters corresponding to the projection equipment according to the equipment information and the first screen projection parameters returned by the projection equipment.
The second screen projection parameters may include resolution, frame rate, compression rate, parameters of whether to acquire and transmit sound, frame rate, and the like of the object to be projected, and may be specifically selected according to actual needs.
After receiving the first screen projection parameters fed back by each projection device, the electronic device determines second screen projection parameters corresponding to each projection device according to the first screen projection parameters, for example, the electronic device determines the resolution of the object to be projected according to the resolution of the projection device, so that the resolution of the object to be projected is matched with the resolution of the projection device; for another example, the frame rate of the electronic device, the timeout time of the TCP interface and reception, the maximum buffer upper limit of the TCP transmission, etc. may be set according to the network signal strength of the projection device; and determining whether the projection equipment has the sound output capability or not according to the parameter representing whether the projection equipment has the sound output capability or not, wherein if the projection equipment does not have the sound output capability, the electronic equipment does not acquire and transmit sound, namely, when the object to be projected is sent to the projection equipment, the sound transmission is not performed, so that network transmission resources and electronic equipment operation resources are saved.
It should be noted that the first screen projection parameter acquired by the projection device may be selected according to actual needs, and the second screen projection parameter of the electronic device may be determined according to the first screen projection parameter fed back by the projection device.
Step S104: and the electronic equipment sends the object to be projected to the corresponding projection equipment according to the second projection screen parameters corresponding to the projection equipment.
After determining the second screen projection parameters corresponding to each projection device, the electronic device performs projection with the second screen projection parameters, for example, adjusting the resolution of the object to be projected to the resolution determined in the second screen projection parameters, and/or compressing the object to be projected according to the compression rate in the second screen projection parameters, and/or sending the object to be projected at the frame rate in the second screen projection parameters, and/or sending the object to be projected to the projection device without sound transmission according to the parameters for which sound acquisition and transmission are not performed in the second screen projection parameters.
By the above manner, the projection method of the embodiment can enable the electronic device to set different second projection parameters for projection of different projection devices when the electronic device is simultaneously connected with the plurality of projection devices, so that the projection parameters of the electronic device can be matched with the projection parameters of each projection device, the problems of projection image blur or projection image proportion mismatch and the like are reduced, and the projection effect is improved.
Further, before step S103, the projection method of the present embodiment further includes the following steps: the method comprises the steps that electronic equipment receives a selection request of a user, wherein the selection request refers to an instruction of the user for selecting an object to be projected; after receiving a selection request of a user, the electronic equipment determines the category of an object to be projected selected by the user according to the selection request, wherein the category of the object to be projected comprises characters, images, videos and the like.
Therefore, acquiring the second screen projection parameters corresponding to each projection device according to the device information and the first screen projection parameters returned by each projection device specifically comprises: and the electronic equipment determines second screen projection parameters corresponding to the projection equipment according to the type of the object to be projected, the equipment information returned by the projection equipment and the first screen projection parameters. Specifically, for three categories of text, image and video, the compression rate in the second screen projection parameter of the electronic device may be set as: text < image < video, frame rate set to: text < image < video, resolution set to: text > image > video, transmission rate set to: text < image < video; that is, when the objects to be projected are text, image and video, respectively, the electronic device sets the compression rates of the text < the compression rate of the image < the compression rate of the video for different objects to be projected, sets the frame rates of the text < the frame rate of the image < the frame rate of the video for different objects to be projected, and analogizes the settings of the resolution and the transmission rate. Therefore, the electronic equipment uses different projection parameters to perform projection corresponding to different categories, and the projection effect is improved.
In this embodiment, after the electronic device sends the object to be projected to the corresponding projection device according to the second screen projection parameter corresponding to each projection device, the method further includes the following steps: the electronic equipment receives first operation information and/or environment information fed back by the projection equipment, wherein the first operation information comprises network signal intensity, load condition, equipment abnormal signal and equipment temperature of the projection equipment, and the environment information comprises environment brightness; the electronic equipment adjusts the second screen projection parameter according to the first running information and/or the environment information; and the electronic equipment sends the object to be projected to the projection equipment according to the adjusted second screen projection parameters.
Specifically, the projection device can acquire first operation information and/or environment information of the projection device in real time in the projection process, and then feed the first operation information and/or the environment information back to the electronic device, so that the electronic device adjusts a second screen projection parameter according to the received feedback information, for example, when the network signal intensity of the projection device is reduced, but the load is normal, and the device abnormal signal indicates no abnormality and the device temperature is normal, the electronic device adjusts the timeout time of a TCP interface to be prolonged, and reduces a TCP transmission buffer area, thereby avoiding data transmission leakage; or when the device temperature of the projection device is too high and the load is too high, the electronic device will lower the frame rate and lower the compression rate.

In the projection process, the electronic device can also monitor the operation information of the electronic device in real time, so that the projection parameters are adjusted in real time according to the operation information of the electronic device, for example, the electronic device monitors that the load of the electronic device is large, the calculation amount of the electronic device can be reduced by reducing the resolution and/or the frame rate of the object to be projected, and the like, and then the object to be projected is sent to the projection device at a lower resolution and/or frame rate to perform projection.
In addition, after the electronic device acquires the second operation information of the electronic device, the method further includes:
the electronic equipment acquires a second correction parameter according to the second operation information;
and the electronic equipment sends the second correction parameter to the projection equipment, so that the projection equipment adjusts the first projection parameter according to the second correction parameter.
The second correction parameter may include, for example, a network adjustment notification, a volume adjustment notification, or a brightness adjustment notification, among others.
Therefore, in the projection method of the embodiment, the first screen projection parameter of the projection device and the second screen projection parameter of the electronic device are adjusted in real time by acquiring the running information of the electronic device and the running information and/or the environmental information of the projection device, so that the screen projection parameters can be adjusted in real time according to the actual projection condition, and the screen projection effect can be improved.
