The set of data transmission metrics includes, but is not limited to, at least one of the following parameters: transmission bandwidth, transmission rate, and transmission delay.

Specifically, for the case of dividing according to the interface content of the application, it can be understood that, since the running interface of the application may include a plurality of running interfaces, and the function associated with each running interface is generally fixed, under the condition that the running interface of the application is relatively stable, the bandwidth, the rate, and the time delay of the electronic device for transmitting the data associated with the running interface are also generally relatively fixed, so that the developer can divide different internal running scenes according to the running interface and configure a suitable data transmission index set for each internal running scene. For example, for a game application, the operation interface of the game application includes a mall interface, a setting interface, a group battle interface, and the like, the data transmission bandwidth, the data transmission rate, and the data transmission delay requirements of the mall interface and the setting interface are relatively low, and the data transmission rate, the data transmission delay requirements of the group battle interface are relatively high, so that an index set with low index requirements can be configured for the inside operation scene corresponding to the mall interface and the setting interface, and an index set with high index requirements can be configured for the inside operation scene corresponding to the group battle interface.

The database can be sent to the intelligent projector by the electronic equipment in advance, and can also be downloaded from the cloud by the local end of the intelligent projector, and the database is not limited uniquely here.

Therefore, in this example, the intelligent projector can quickly acquire the data transmission index set matched with the current scene identifier by querying the pre-stored database, so as to accurately locate the index set capable of meeting the data transmission requirement of the current scene, and further create a target transmission channel meeting the requirement, which is beneficial to improving the accuracy and the real-time performance of the playing control of the intelligent projector.

As can be seen, in this example, for a scene in which the electronic device is wirelessly connected, the intelligent projector may enable the first wireless communication module supporting the high index requirement based on the high resolution video requirement, and instruct the electronic device to enable the adaptive second communication module, so as to create a target transmission channel according to a protocol supported by the first and second wireless communication modules, and receive screen projection data through the target transmission channel, thereby implementing dedicated channel configuration for an internal operating scene, and improving intelligence and accuracy of playing control performed by the intelligent projector.

In one possible example, the target application comprises a video application, and an internal running scene of the video application comprises a video content playing scene with a target resolution; the intelligent projector establishes a target transmission channel according to the data transmission index set, and the method comprises the following steps: the intelligent projector determines to use a first port and a second port according to the data transmission index set, wherein the first port and the second port are high-definition digital display interfaces (displayports) or high-definition multimedia interfaces (HDMI), the first port is arranged on the intelligent projector, and the second port is arranged on the electronic equipment; detecting the connection state of a first port of the intelligent projector and a second port of the intelligent projector; and when detecting that the first port and the second port are in a connected state, creating a target transmission channel according to the first port and the second port.

Therefore, in the example, the intelligent projector can intelligently select the high-definition video port for data transmission according to the resolution requirement of the video content aiming at the wired connection scene, so that the content to be played can be smoothly played, and the playing control intelligence of the intelligent projector is improved.

In one possible example, the target application comprises a game application, an internal execution scenario of the game application comprises a group battle scenario; the intelligent projector establishes a target transmission channel according to the data transmission index set, and the method comprises the following steps: the intelligent projector determines a target communication module and a target interface which are adapted to the group battle scene according to the data transmission index set, wherein the target communication module comprises a first communication module and a second communication module, the first communication module and the second communication module are high-definition digital display interfaces (HDPLAP) or high-definition multimedia interfaces (HDMI), the first port is arranged on the intelligent projector, the second port is arranged on the electronic equipment, the target interface comprises a first interface and a second interface, the first interface and the second interface are high-definition digital display interfaces (HDPLAP) or high-definition multimedia interfaces (HDMI), the first port is arranged on the intelligent projector, and the second port is arranged on the electronic equipment; enabling the first communication module and the second communication module, and setting the first port and the second port to be in a connection state; and creating a first transmission channel according to the first wireless communication module and the second wireless communication module, and creating a second transmission channel according to the first port and the second port, wherein the first transmission channel is used for transmitting the image data of the group battle scene, the second transmission channel is used for transmitting the voice data of the group battle scene, and the screen projection data comprises the image data and the voice data.

The group battlefield scene refers to a scene in which multiple users play games synchronously in the same game map.

As can be seen, in this example, since the group battle scene is not only large in data volume but also low in required delay, different data transmission channels can be created to transmit the image data and the voice data in the group battle scene respectively, so that the image data and the voice data are transmitted in parallel, the data transmission rate is increased, the play delay is reduced, and the screen projection stability and smoothness are improved.

In one possible example, before the smart projector receives a screen projection request from the electronic device, the method further comprises: the intelligent projector acquires gesture actions of a user through the millimeter wave antenna array module; and when the gesture action of the user is detected to be a preset gesture action, starting the intelligent projector.

The preset hand action may be any personalized action configured by a user, or a fixed gesture action pre-configured by a developer, and is not limited herein.

Therefore, in the example, the intelligent projector can collect gesture actions of the user through the millimeter wave antenna array module, the intelligent projector can be conveniently started through gesture action comparison, the user does not need to press physical keys or operate through a remote controller and the like, and operation convenience is improved.

In one possible example, the method further comprises: the intelligent projector acquires content data being played when detecting a discharge instruction; determining the minimum electric quantity for playing the content by the local terminal according to the content data; determining dischargeable electric quantity according to the residual electric quantity of the local terminal and the minimum electric quantity; and performing a discharging operation according to the dischargeable electric quantity.
