With the rapid development of automobile technology, in the field of vehicle consumption, people change from traditional consumption meeting the use of vehicle functions to new consumption pursuing the life experience of vehicles, the number of screens in the vehicles also becomes more and more, and different vehicle-to-machine systems can be respectively corresponding to different screens.
Currently, a screen in a car system also has a screen throwing capability, for example, to receive and output multimedia content thrown by electronic devices such as a mobile phone, a tablet and the like. However, because the corresponding car machine systems between different screens independently operate, when the screen switching is required between different screens, the transmission of the multimedia resources can only be performed in the form of video stream copying. Therefore, when the user switches and plays the multimedia content between different screens, the problem of high switching delay of the screen of the multimedia data is particularly obvious.
Aiming at the problem, the embodiment of the application provides a screen switching method, a device, electronic equipment, a readable storage medium and a vehicle, which can reduce the time delay of screen switching and improve the stability of screen switching.
In the embodiment of the application, the screen switching method can be applied to a first vehicle system, and a screen data transmission path is arranged between the first vehicle system and each second vehicle system.
For example, a plurality of vehicle systems may be included in a vehicle, each of which may be built based on a System on Chip (SoC). Optionally, in the system-on-chip, for example, a central processing unit (Central Processing Unit, CPU), an image processing unit (Graphics Processing Unit GPU), a signal processor (Digital Signal Processing, DSP), a neural network processing unit (Natural Processing Unit NPU), and memory and various types of Input/Output (I/O) interfaces, etc. may be integrated, without specific limitation. A complete control system may be included in the vehicle system, and software applications may also be embedded. For example, an interface system can be preset in the vehicle-mounted system, and the interface system can receive and output multimedia contents put in electronic equipment such as a mobile phone, a tablet and the like, so that interaction between the vehicle-mounted system and the electronic equipment is realized.
As a specific example, a plurality of screens included in one vehicle, for example, a center control screen, a co-driver screen, a sunroof screen, a rear passenger screen, and the like. Different car machine systems can be corresponding to different screens, and the same car machine system can be corresponding to two screens, so that specific limitation is not adopted. Specifically, for example, the first vehicle system is equipped with a screen a, and the second vehicle system is equipped with a screen B and a screen C. After the electronic device performs screen projection on the screen A in the first vehicle system, based on the screen projection switching method provided by the embodiment of the application, the multimedia content corresponding to the screen projection can be rapidly switched to the screen B of the second vehicle system.
The following describes a screen-switching method provided by an embodiment of the present application with reference to the accompanying drawings, and fig. 1 shows a schematic flow chart of the screen-switching method provided by an embodiment of the present application. As shown in fig. 1, the screen-shot switching method may include steps 110 to 150.
Step 110, controlling the first multimedia output end to output the screen-throwing data.
Specifically, the screen projection data includes multimedia content, and an electronic device such as a mobile phone, a tablet, or the like can acquire the multimedia content. Exemplary, multimedia content such as video, pictures, audio, text, and the like. The multimedia content may come from a network, may come from a storage space local to the electronic device, and is not particularly limited herein.
In some embodiments, the electronic device may transmit the screen projection data to the first vehicle system by mirroring the screen projection, or by on-line screen projection. A microcontroller (Microcontroller unit, MCU) for processing the screen throwing data CAN be further configured in the vehicle, communication interaction CAN be carried out between the MCU and the first vehicle system through a controller area network (Controller Area Network, CAN), the electronic equipment CAN also select to access the MCU, and the screen throwing data are transmitted to the first vehicle system through the MCU.
Before the first vehicle system receives the screen projection data sent by the electronic device and controls the first multimedia output end in the first vehicle system to output the screen projection data, the screen projection output resolution of the screen projection data can be preset. For example, the first vehicle system may include the following steps before receiving the screening data: and receiving screen-throwing control information, wherein the screen-throwing control information comprises screen-throwing output resolution of the multimedia output end. Next, receiving the transmitted screen projection data of the electronic device, and controlling the first multimedia output end in the first vehicle system to output the screen projection data, which may specifically include: receiving screen throwing data sent by electronic equipment; and controlling the first multimedia output end to output the screen-throwing data according to the screen-throwing output resolution.

It will be appreciated that the first vehicle control system may receive user input to the adjustment control during the screen projection process, or may receive user input to the adjustment control prior to the start of the screen projection process. After the first vehicle system obtains the screen-throwing control information, the first multimedia output end can be controlled to output the screen-throwing data based on the screen-throwing output resolution.
The first vehicle control system can also perform communication interaction with the MCU, and receives screen-throwing control information sent by the MCU. As a specific example, fig. 2 is a schematic structural diagram of a projection data transmission system according to an embodiment of the present application. As shown in fig. 2, the MCU may include a video signal query chip or a video signal control chip, and when the multimedia content includes video data, the MCU may perform information interaction with the electronic device based on the video signal query chip or the video signal control chip, to determine the screen output resolution of the video. For example, in the information interaction process, for example, when the user inputs the screen-throwing output resolution through the electronic device, the MCU sends the screen-throwing output resolution input by the user to the first vehicle system, so that the first vehicle system can control the first multimedia output end to output the screen-throwing data according to the screen-throwing output resolution. Under the condition that the user does not input the screen-throwing output resolution, the MCU can also determine the screen-throwing output resolution according to the resolution of the video data, and when the output resolution of the first multimedia output end can meet the resolution of the video data, the resolution of the video data can be used as the screen-throwing output resolution. The screen input resolution may be set according to the application scenario, and is not particularly limited herein.
According to the embodiment of the application, the screen-throwing output resolution of the first multimedia output end can be conveniently adjusted, and the flexibility of screen-throwing control is improved.
In some embodiments, the first multimedia output comprises a first display screen and a first audio output unit; receiving the screen projection data sent by the electronic device, and controlling a first multimedia output end in a first vehicle machine system to output the screen projection data, wherein the method specifically comprises the following steps: receiving screen throwing data sent by electronic equipment; analyzing the screen throwing data to obtain image data and/or audio data; when the screen throwing data are analyzed to obtain image data, displaying the image data based on a first display screen; when the screen throwing data are analyzed to obtain audio data, the audio data are played based on the first audio output unit.
Optionally, a chip based on a Power Delivery Protocol (PD) may be configured in the MCU, and when the electronic device may further select to access the MCU, the MCU may transmit the screen-projection data to the first vehicle system, so that a transmission rate of the screen-projection data between the electronic device and the MCU may be improved.
In some embodiments, the first display screen and the first audio output unit in the first vehicle system take the example that the projection data includes video data, and the first vehicle system may parse the video data to obtain image data and audio data. After obtaining the image data, transmitting the image data to a first display screen for display through a CameraServer; after the audio data is obtained, the audio data can be transmitted to the first audio output unit for playing through AudioService. Among them, the functions of the camera server include turning on/off a first display screen, resolution setting, resolution change notification, displaying image data, resolution query, displaying link copy, and the like. The AudioService functions include audio focus control, audio channel control, and the like. In some embodiments, the MCU may further directly parse the video data to obtain image data and audio data, and then may directly send the image data and the audio data to the first vehicle system, so as to improve the adaptation capability of the MCU.
In this embodiment of the present application, when the user wants to switch the multimedia output end when the first multimedia output end in the first vehicle system outputs the screen-casting data, a screen-casting switching request may be sent to the first vehicle system, specifically as step 120.
And 120, when receiving a screen switching request carrying identification information, determining a target vehicle system to which a target multimedia output end corresponding to the identification information belongs from at least one second vehicle system.
Specifically, the screen-drop switching request includes that the user wants to switch to the target multimedia output terminal. For example, after the electronic device performs screen projection on the screen a in the first vehicle system, if the user wants to switch the screen projection to the screen B of the second vehicle system, the electronic device may select to project the screen to the screen B, so that the first vehicle system may receive the screen projection switching request. For another example, the user may set the screen B for selecting the switch in the first vehicle system, and thus the first vehicle system may also receive the screen switching request.
In the embodiment of the present application, each multimedia output terminal corresponds to one screen identification information, that is, a screen ID. According to the screen identification information, the first vehicle system can quickly determine the target vehicle system from the second vehicle system so as to switch the screen to the target multimedia output end in the target vehicle system.
And step 130, sending a first screen throwing request to the target vehicle machine system.
The method comprises the steps that a first screen throwing request is sent to a target vehicle machine system, so that the target vehicle machine system can respond to the first screen throwing request to start a display screen, and the display screen comprises a CameraServer; the target vehicle system may further start the first audio output unit in response to the first screen projection request, for example, specifically including AudioService. When the target vehicle system needs to start the first audio output unit, the audio focus can be applied, so that the audio data can be output from the first audio output unit corresponding to the target vehicle system.
And 140, responding to the screen-throwing starting information fed back by the target vehicle machine system, and sending a first control signal to a screen-throwing data transmission channel corresponding to the target vehicle machine system to control the screen-throwing data transmission channel to be conducted.
Specifically, after the multimedia output end of the target vehicle machine system is started, the screen-throwing starting information can be fed back to the first vehicle machine system, and the first vehicle machine system can send a first control signal to the screen-throwing data transmission channel corresponding to the target vehicle machine system in response to the screen-throwing starting information so as to conduct the screen-throwing data transmission channel.
In some embodiments, after sending the first screen-throwing request to the target vehicle machine system, the first vehicle machine system may further detect an operation state of the first multimedia output end in response to screen-throwing start information fed back by the target vehicle machine system; when the running state of the first multimedia output end is the output state, the running state of the first multimedia output end is controlled to be the closing state.
Specifically, for example, after the first vehicle machine system receives the screen-throwing start information fed back by the target vehicle machine system, it can be judged whether the first multimedia output end in the system is still continuously outputting the screen-throwing data. When the running state of the first multimedia output end is the output state, the running state of the first multimedia output end is controlled to be the closing state.
Specifically, controlling the running state of the first multimedia output terminal to be the off state includes: controlling the first display screen to stop displaying the image data; and controlling the first audio output unit to stop playing the audio data.
For example, when the display screen outputs the image data, the display screen in the first vehicle system may be turned off, stopping outputting the image data. The first vehicle system also detects whether the audio output unit is in an audio output state, and when the first audio output unit is in the audio output state, the first vehicle system can release the audio focus at the time, so that the first audio output unit is controlled to stop playing audio data, and the audio data can be output from a target multimedia output end in the target vehicle system.
And step 150, transmitting the screen throwing data to the target vehicle machine system through the screen throwing data transmission path so that the target vehicle machine system controls the target multimedia output end to output the screen throwing data.
The first vehicle system sends the screen throwing data to the target vehicle system through the data transmission channel so that the target vehicle system controls the target multimedia output end to output the screen throwing data.
In some embodiments, after sending the first control signal to the corresponding on-screen data transmission path of the target vehicle system, the method further includes: and controlling the first multimedia output end to stop outputting the screen throwing data. In an exemplary embodiment, after the first vehicle system sends the screen projection data to the target vehicle system through the data transmission path, the first multimedia output end in the first vehicle system may be controlled to stop outputting the screen projection data. For example, the first display screen no longer displays the image data in the screen-in data, and the audio output unit no longer outputs the audio data in the screen-in data.
In the embodiment of the application, since the screen-throwing data transmission channel is arranged between the first vehicle machine system and the target vehicle machine system, the first vehicle machine system controls the screen-throwing data transmission channel to be conducted by sending the first control signal to the screen-throwing data transmission channel, and then the screen-throwing data is sent to the target vehicle machine system through the data transmission channel, so that the target multimedia output end can be directly controlled to output the screen-throwing data after the screen-throwing data is received by the target vehicle machine system, the processing procedures such as decompression and the like are not needed for the screen-throwing data, the time delay of the screen-throwing switching is effectively reduced, and the stability of the screen-throwing switching is improved.
As a specific example, the drop data transmission path includes a hardware video stream replication link of the deserializer; the step 140 may specifically include: and sending a first control signal to a screen-throwing data transmission channel corresponding to the target vehicle machine system so as to start a hardware video stream copying link of a deserializer in the screen-throwing data transmission channel.
The hardware video stream replication link of the deserializer can comprise a video signal deserializer and the like, and high-speed data communication can be realized through the hardware video stream replication link of the deserializer.
In some embodiments, a first control signal to initiate a hardware video stream replication link of the deserializer may be preset. For example, the first control signal may be high, i.e. by applying the first level to the hardware video stream replica link of the deserializer, turning on the hardware video stream replica link of the deserializer.
When the target vehicle machine system receives the screen throwing data based on the hardware video stream copying link of the deserializer, the multimedia output end is switched from the first multimedia output end to the target multimedia output end.
The above step 150 is specifically related to transmitting the screen-throwing data to the target vehicle system through the hardware video stream duplication link of the deserializer. For a plurality of vehicle-mounted systems of the same vehicle content, the screen-mounted data is transmitted by fully utilizing the hardware channels duplicated by video links among different vehicle-mounted systems, so that the screen-mounted data can be directly output by the target multimedia output end without processing processes such as decompression and the like on the screen-mounted data, thereby effectively reducing the time delay of screen-mounted switching and improving the stability of screen-mounted switching.
As another specific embodiment, based on the same inventive concept, the screen switching method of the present application may also be applied to a second vehicle system, where the second vehicle system is connected to the first vehicle system in a communication manner, and a screen switching data transmission path is included between the second vehicle system and the first vehicle system, and the second vehicle system includes a target multimedia output end, and the method includes: receiving a first screen projection request sent by a first vehicle machine system; responding to a first screen-throwing request, and feeding back screen-throwing starting information to a first vehicle machine system; receiving screen throwing data sent by a first vehicle machine system through a data transmission channel; and controlling the target multimedia output end to output the screen throwing data.
In some embodiments, the drop data transmission path includes a hardware video stream replication link of the deserializer; receiving screen projection data sent by a first vehicle machine system through a data transmission path, wherein the screen projection data comprises: and receiving the hardware video stream replication link transmission screen throwing data of the first vehicle system through the deserializer.
The hardware video stream replication link of the deserializer can comprise a video signal deserializer and the like, and high-speed data communication can be realized through the hardware video stream replication link of the deserializer. When the target vehicle machine system receives the screen throwing data based on the hardware video stream copying link of the deserializer, the multimedia output end is switched from the first multimedia output end to the target multimedia output end.
In the embodiment of the application, since the screen-throwing data transmission channel is arranged between the first vehicle machine system and the target vehicle machine system, the first vehicle machine system controls the screen-throwing data transmission channel to be conducted by sending the first control signal to the screen-throwing data transmission channel, and then the screen-throwing data is sent to the target vehicle machine system through the data transmission channel, so that the target multimedia output end can be directly controlled to output the screen-throwing data after the screen-throwing data is received by the target vehicle machine system, the processing procedures such as decompression and the like are not needed for the screen-throwing data, the time delay of the screen-throwing switching is effectively reduced, and the stability of the screen-throwing switching is improved.
For more clear explanation of the embodiment of the present application, fig. 3 is a schematic diagram of another screen-switching flow provided in the embodiment of the present application. In connection with fig. 3, the MCU may send the screen-throwing data to a first screen-throwing control Application (APP) corresponding to the first vehicle system, where in a process of outputting the screen-throwing data by the first vehicle system, the first screen-throwing control APP may receive a screen-throwing switching request, where the screen-throwing switching request includes screen identification information. Taking the example that the screen identification information corresponds to the multimedia output end of the second vehicle system, after the first screen-throwing control APP receives the screen-throwing switching request, the first vehicle system sends a notification for starting the multimedia output end to the DevCtrlService in the second vehicle system through the DevCtrlService. After the DevCtrlService in the second machine system receives the notice, the second screen-throwing control APP is started, and the CameraService and the audioService are started. After the camera service is started, a camera data stream, specifically, for example, image data, may be requested from the camera server. After the multimedia output terminal in the second vehicle system is started, feedback information, for example, that the multimedia output terminal of the second vehicle system is started, may be sent to the DevCtrlService in the first vehicle system. After receiving the feedback information, the first vehicle machine system can confirm the self-screen-throwing state, and close the self-image output end, such as the CameraService, and release the audio focus under the condition that the self-screen-throwing is started. And then starting the CameraService in a mode of not displaying the image so as to continuously receive the screen projection data. After the first vehicle system is successfully started by the camera service, a notification of the success of the starting of the camera service can be sent to the second vehicle system, and correspondingly, after the second vehicle system receives the notification, the second vehicle system requests to start the hardware video stream replication link of the deserializer to the first vehicle system. After the DevCtrlService in the first vehicle system receives the request, the request can be forwarded to the first screen-throwing control APP so that the first screen-throwing control APP can be sent to the second vehicle system through the hardware video stream replication link of the deserializer, and the second vehicle system can conveniently output screen-throwing data through the multimedia output end to realize screen-throwing switching.
