Examples
In order to solve the problem that the screen projection use experience of a user is influenced due to the fact that audio and video resources are synchronously played on screen projection equipment in the prior art, the invention aims to provide a screen projection method, a screen projection device, screen projection equipment, a screen projection system and a storage medium.
First, in order to more intuitively understand the scheme provided by the embodiment of the present application, a system architecture of the screen projection scheme provided by the embodiment of the present application is described below with reference to fig. 1.
Fig. 1 is a schematic application environment diagram of a screen projection method, apparatus, device and storage medium according to one or more embodiments of the present application. As shown in fig. 1, the mobile terminal establishes a communication connection with the screen projection device, so that the audio and video resources of the mobile terminal are projected on the screen projection device for playing. The mobile terminal may be, but is not limited to, a tablet computer, a smart phone, a Personal Digital Assistant (PDA), and the like, and the screen projection device may be a smart television, a large screen device for projecting a screen, and the like.
As shown in fig. 2, which is a flowchart of a screen projection method applied to a screen projection device provided in an embodiment of the present application, the screen projection method may include the following steps:
step S201, receiving an audio resource playing instruction initiated by the mobile terminal.
The audio resource playing instruction initiated by the mobile terminal can be triggered in response to the operation of the user. For example, a control for initiating an audio resource playing instruction may be set on a screen projecting application interface of the mobile terminal, and when a user wants to play an audio resource in a screen projecting audio and video resource on the mobile terminal side, the user may touch the control on the screen projecting application interface of the mobile terminal, and at this time, the mobile terminal generates an audio resource playing instruction and sends the instruction to a screen projecting device currently projecting a screen. And the audio resource playing instruction is used for indicating that the audio resource in the audio and video resource needing to be projected is played on the mobile terminal side.
In the embodiment of the application, the audio resource playing instruction is triggered in response to the operation of the user. It is understood that in some other embodiments, the audio resource playing command may be triggered by other triggering manners, for example, by voice control or some other operation on the mobile terminal (e.g., the mobile terminal is connected to a headset via a wired or bluetooth connection).
And S202, establishing an audio media channel with the mobile terminal.
After receiving an audio resource playing instruction initiated by the mobile terminal, the screen projection device establishes an audio media channel with the mobile terminal, wherein the audio media channel is used for sending audio resources.
In the embodiment of the application, the audio resource can be directly played through a loudspeaker at the mobile terminal, and can also be played only through a headset connected with the mobile terminal.
And when the audio resource can be directly played at the mobile terminal through the loudspeaker, an audio media channel is established with the mobile terminal after receiving an audio resource playing instruction initiated by the mobile terminal.
For the situation that the audio resource can only be played through the headset connected with the mobile terminal, the headset connection state of the mobile terminal can be carried in the audio resource playing instruction initiated by the mobile terminal, and the headset connection state can be connected or disconnected. And when the headset connection state carried in the audio resource playing instruction represents that the mobile terminal is currently connected with the headset, establishing an audio media channel with the mobile terminal. And when the headset connection state carried in the audio resource playing instruction represents that the mobile terminal is not connected with the headset currently, an audio media channel cannot be established with the mobile terminal.
In the embodiment of the application, the screen projection equipment can also pause playing of the audio and video resources being played when receiving the audio resource playing instruction initiated by the mobile terminal. It can be understood that, in some other embodiments, the screen projecting device may also continue to play the audio and video resources being played in the process of establishing the audio media channel with the mobile terminal after receiving the audio resource playing instruction initiated by the mobile terminal.
And S203, forwarding the audio resource in the audio and video resource to the mobile terminal through the audio media channel so as to play the forwarded audio resource on the mobile terminal.
The audio and video resources from the screen of the mobile terminal to the screen projecting device comprise audio resources and video resources, after an audio media channel is established with the mobile terminal, the screen projecting device can forward the audio resources in the audio and video resources to the mobile terminal, and the mobile terminal plays the forwarded audio resources after receiving the audio resources forwarded by the screen projecting device.
And S204, playing the video resource in the audio and video resource.
In the embodiment of the application, because the audio resources in the audio and video resources are sent to the mobile terminal and played at the mobile terminal, the screen projection device only needs to play the video resources in the audio and video resources at present, that is, the screen projection device plays the video resources in the audio and video resources, and stops playing the audio resources in the audio and video resources. Therefore, the video resource in the audio and video resource can be played on the screen projection equipment, and the audio resource in the audio and video resource can be played on the mobile terminal. When the audio sound played by the screen projection equipment is small or the user is far away from the screen projection equipment, the audio played by the screen projection equipment cannot be clearly heard, the mode can be adopted, the user can conveniently and clearly hear the audio content while the screen projection is realized, and therefore the screen projection use experience of the user is improved. Furthermore, the audio resources can be played through the headset connected with the mobile terminal, the played audio cannot interfere with other people, and user experience is further improved.
In the embodiment of the application, the screen projection equipment consumes a certain time in the process of forwarding the audio resource to the mobile terminal through the audio media channel, if the consumed time is short, the audio resource and the video resource can be basically kept synchronous, and a user cannot generate the feeling of audio lag. At this time, the video resource may be played while the audio resource is forwarded to the mobile terminal through the audio media channel.
If the time consumed by the screen projection equipment in the process of forwarding the audio resource to the mobile terminal through the audio media channel is long, the audio resource and the video resource cannot be kept synchronous, and if the video resource is played according to the normal playing progress all the time, a user can generate the feeling of audio lag. At this time, the video resource may be delayed from being played while the audio resource is forwarded to the mobile terminal through the audio media channel. The delay time is the estimated time for forwarding the audio resource to the mobile terminal through the audio media channel, and the estimated time can be determined according to multiple tests.
For example, the time consumed by the screen projection device in the process of forwarding the audio resource to the mobile terminal through the audio media channel is 400 milliseconds, and the time taken by the screen projection device to forward the audio resource to the mobile terminal through the audio media channel is 11 hours, 22 minutes, 33 seconds and 200 milliseconds, so that the video resource can be delayed to be played by 400 milliseconds. I.e. it can pause for 400 ms from 200 ms starting at 11 h 22 min 33 s and continue to play the video resource normally until 600 ms starting at 11 h 22 min 33 s.
Further, if the audio resource can only be played through the headset connected with the mobile terminal, the mobile terminal can also send the current headset connection state of the audio resource to the screen projection device in real time, the screen projection device obtains the current headset connection state of the mobile terminal in real time, and when the current headset connection state of the mobile terminal represents that the mobile terminal is not connected with the headset currently, the audio resource is stopped being forwarded to the mobile terminal and the audio resource in the audio and video resource is played synchronously. Therefore, the audio can be automatically switched to be played by the screen projection device when the mobile terminal is disconnected from the headset.
Therefore, by the screen projecting method described in the foregoing steps S201 to S204, an audio media channel is established with the mobile terminal in the screen projecting process, and the audio resource in the audio and video resource is forwarded to the mobile terminal through the audio media channel to be played, and the video resource in the audio and video resource is played at the screen projecting device, so that the audio resource can be played on the mobile terminal at the user side as required during screen projection, and the screen projecting experience of the user is improved. Meanwhile, the audio resources can be played through the headset connected with the mobile terminal, the played audio cannot interfere with other people, and user experience is further improved. Secondly, if the time consumed by the screen projection equipment in the process of forwarding the audio resource to the mobile terminal through the audio media channel is long, the video resource can be delayed to be played when the audio resource is forwarded to the mobile terminal through the audio media channel, so that the audio and the video are kept synchronous, the feeling of audio lag is not generated, and the screen projection effect is guaranteed. In addition, the current headset connection state of the mobile terminal can be acquired in real time, and when the current headset connection state of the mobile terminal represents that the mobile terminal is not connected with a headset currently, the forwarding of the audio resource to the mobile terminal is stopped, and the audio resource in the audio and video resource is played synchronously. Therefore, the audio can be automatically switched to be played by the screen projection equipment when the mobile terminal is disconnected from the headset.
