At present, the screen projection technology is integrated into life and work of people, and is widely applied to scenes such as conferences, teaching and the like. With the rapid development of screen projection technology, the one-to-one screen projection mode is difficult to meet the requirements of users, and therefore, one-to-many, many-to-one and the like screen projection modes are generated.
Generally, in a many-to-one screen projection mode, the screen projection receiving terminal and the screen projection transmitting terminals are included, each screen projection transmitting terminal transmits screen projection resources to be projected to the screen projection receiving terminal, and after the screen projection receiving terminal receives the screen projection resources, since each screen projection resource needs to be compressed and the like, a large amount of computing resources need to be consumed, and the problems of screen projection screen blocking, blocking and the like are easily caused.
Based on this, the embodiment of the application provides a screen projection method to reduce resource consumption of a screen projection receiving end and reduce the problems of screen projection screen blocking, deadlocking and the like.
Referring to fig. 1, fig. 1 is a flowchart of a screen projection method according to an embodiment of the present disclosure. As shown in fig. 1, a screen projection method provided in an embodiment of the present application is applied to a screen projection receiving end, and includes:
s101, responding to a screen projection control event, and determining a screen projection sending end corresponding to the screen projection control event.
In this step, the screen-casting receiving end may be connected to one or more screen-casting sending ends, and receive screen-casting resources sent by each screen-casting sending end, and when a screen-casting control event is detected, the screen-casting sending end corresponding to the screen-casting event may be determined according to the screen-casting event and the currently accessed screen-casting sending end.
In one possible embodiment, the screen-projection control event includes at least one of:
the method comprises the steps of detecting a screen throwing adding request corresponding to any screen throwing sending end, detecting a screen throwing withdrawing request corresponding to any screen throwing sending end and detecting a screen throwing equipment deleting instruction.
Here, the user may control the number of screen-casting transmitting terminals connected to the screen-casting receiving terminal and transmitting the screen-casting resources through the screen-casting receiving terminal or in another manner, and the screen-casting receiving terminal and the screen-casting transmitting terminal may implement screen casting through Wi-Fi (wireless internet access), DLNA (DIGITAL LIVING NETWORK ALLIANCE ), WiDi (intel wireless display, wireless high definition technology), AirPlay (AirPlay), and the like.
Here, the screen projection transmitting terminal and the screen projection receiving terminal may be terminals with a screen projection function, such as a smart phone, a computer, and a tablet computer.
When the screen-casting control event is a screen-casting addition request sent by a screen-casting sending terminal, the screen-casting sending terminal which has currently established screen-casting connection with the screen-casting receiving terminal and the screen-casting sending terminal which sends the screen-casting addition request can be used as the screen-casting sending terminal corresponding to the screen-casting control event; when the screen-casting control event is a screen-casting exit request, the connection between a screen-casting receiving terminal and a screen-casting sending terminal sending the screen-casting exit request can be disconnected, a screen-casting window corresponding to the screen-casting sending terminal sending the screen-casting exit request is closed, and then the screen-casting sending terminal which is currently in screen-casting connection with the screen-casting receiving terminal is determined to be the screen-casting sending terminal corresponding to the screen-casting control event; when the screen-casting control event is a screen-casting device deletion instruction, the screen-casting connection between the screen-casting receiving terminal and the screen-casting sending terminal indicated by the screen-casting device deletion instruction can be disconnected, and the screen-casting sending terminal which establishes the screen-casting connection with the screen-casting receiving terminal after disconnection is determined to be the screen-casting sending terminal corresponding to the screen-casting control event.
S102, screen projection parameters corresponding to each screen projection sending end are determined according to the number of the screen projection sending ends.
In this step, after determining the number of screen-projecting sending terminals corresponding to the screen-projecting control event, the graphical user interface of the screen-projecting receiving terminal may be divided into a plurality of display areas according to the number of screen-projecting sending terminals, each display area may correspond to one screen-projecting sending terminal, and a screen-projecting window corresponding to the screen-projecting sending terminal is generated in the display area, and the size of each screen-projecting window may be the same or different. After the screen projection windows are generated, the size of each screen projection window can be used as the corresponding screen projection parameter. The size of the screen projection window is a specific numerical value capable of representing the size and the shape of the screen projection window. The screen projection sending terminal can set screen projection resources sent by the screen projection sending terminal based on the screen projection parameters so as to adapt to the size of a screen projection window. The screen projection receiving end can directly display the screen projection resources in the corresponding screen projection window after receiving the screen projection resources, the screen projection receiving end is prevented from compressing the screen projection resources and the like, the occupation of computing resources of the screen projection receiving end is effectively reduced, and the situations of blockage, blockage and the like of screen projection pictures are reduced.
S103, sending the screen projection parameters to the corresponding screen projection sending ends, so that the screen projection sending ends send screen projection resources to the screen projection receiving ends according to the screen projection parameters.
In this step, after the screen projection receiving end sends the screen projection parameters to each screen projection sending end, the screen projection receiving end can determine the resolution and the code rate for pushing the screen projection resources according to the received screen projection parameters, and send the screen projection resources to the screen projection receiving end according to the determined resolution and code rate. For example, the resolution and the code rate of the screen projection resources can be determined according to the mapping relationship between the screen projection parameters and the resolution and the code rate.
For the screen projection sending end which establishes screen projection connection with the screen projection receiving end, the sending of the original screen projection resource can be interrupted, the screen projection resource is collected again according to the resolution and the code rate corresponding to the newly received screen projection parameter, and the screen projection resource is sent to the screen projection receiving end; and for the newly added screen projection sending end which does not establish screen projection connection with the screen projection receiving end, directly re-collecting screen projection resources according to the resolution and code rate corresponding to the received screen projection parameters, and sending the re-collected screen projection resources to the screen projection receiving end.
And S104, receiving and displaying the screen projection resources sent by each screen projection sending terminal.
Therefore, when the number of the screen-casting sending ends is increased or decreased, the screen-casting sending ends can determine the screen-casting parameters of each screen-casting sending end according to the number of the new screen-casting sending ends, and enable the screen-casting sending ends to transmit screen-casting resources according to the screen-casting parameters.
Because the screen projection resources received by the screen projection sending end are screen projection resources matched with the screen projection window, operations such as compression and the like are not needed, processing performed by the screen projection receiving end can be dispersedly transferred to the screen projection sending end, the occupation of running resources of the screen projection receiving end is effectively reduced, and the problems of screen projection screen blocking, blocking and the like caused by overhigh resource occupation are reduced.
Referring to fig. 2, fig. 2 is a flowchart of a screen projection method according to another embodiment of the present application. The descriptions of S201, S204, and S205 may refer to the descriptions of S101, S103, and S104, respectively, and the same technical effect can be achieved, which is not described in detail herein.

Illustratively, if the number of the screen-casting sending terminals is three, screen-casting windows in a four-grid form can be generated, wherein three screen-casting windows respectively display screen-casting resources sent by one screen-casting sending terminal, and the remaining screen-casting windows are in a standby state; if the number of the screen-casting sending ends is increased to five, generating a screen-casting window in a six-grid form; or generating screen projection windows with equal or similar proportions according to the display size of the screen projection sending end.
S203, determining screen projection parameters corresponding to each screen projection sending end according to the screen projection windows, wherein the screen projection parameters comprise screen projection window sizes of the screen projection resources.
In this step, after the screen projection windows are generated, the size of each screen projection window can be determined, and after the screen projection sending end receives the corresponding screen projection window size, the resolution and the code rate of the screen projection resource can be determined, so that the screen projection resource is collected according to the determined resolution and code rate and is sent to the screen projection receiving end.
Specifically, the resolution and the code rate of the screen projection resource can be determined according to the corresponding relationship among the preset size, the preset resolution and the preset code rate.
And S204, sending the screen projection parameters to the corresponding screen projection sending end, so that the screen projection sending end sends screen projection resources to the screen projection receiving end according to the screen projection parameters.
And S205, receiving and displaying the screen projection resources sent by each screen projection sending terminal.
In a possible implementation manner, the sending the screen-casting parameter to the corresponding screen-casting sending terminal so that the screen-casting sending terminal sends the screen-casting resource to the screen-casting receiving terminal according to the screen-casting parameter includes:
and aiming at each screen projection sending end, sending the screen projection window size of the screen projection resource corresponding to the screen projection sending end, so that the screen projection sending end determines the resolution and the code rate of the screen projection resource according to the screen projection window size, and sends the screen projection resource to the screen projection receiving end according to the determined resolution and code rate.
Therefore, the performance resource consumption of the screen projection receiving end can be optimized, the performance consumption of the screen projection receiving end cannot be increased by multiple times when multiple paths of screens are projected, smooth operation of the screen projection receiving end can be guaranteed, and the resolution and the code rate of the screen projection resources sent by the screen projection sending end are coded according to the size given by the screen projection receiving end, so that the size of a data stream of the receiving end does not need to be compressed at the screen projection receiving end, and the screen projection receiving end can be clearly displayed in a screen projection window of the screen projection receiving end. Therefore, the problem of definition of the screen projection window at the receiving end is solved.
Because the sent data is optimized data, excessive unnecessary data is not transmitted in the transmission process, so that network resources, CPU resources and memory resources of the screen projection sending end and the screen projection receiving end are saved, and the usability of software is greatly improved.
