Description

[0002] Currently, most in-vehicle devices have the function of playing Bluetooth music. However, when casting audio applications from a terminal device to an in-vehicle device, due to application incompatibility or system permission restrictions, the in-vehicle device cannot obtain detailed information about the playback content in the audio application, such as song title, artist information, playback progress, or lyrics. The in-vehicle device's interface only displays the audio playback interface set by the system. If users need to obtain more detailed audio information, they need to obtain it from a mobile phone with a smaller screen, which reduces the utilization rate of the in-vehicle screen and is also detrimental to driving safety.

The presentation of this phrase in various locations throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] To better understand the information processing method and related products provided in the embodiments of this application, the system architecture of the information processing method applicable to the embodiments of this application will be described below.

[0045] Please see Figure 1A , Figure 1A This is a schematic diagram of the architecture of the information processing system provided in an embodiment of this application. Figure 1A As shown, the system architecture may include in-vehicle equipment and terminal equipment, and the terminal equipment and in-vehicle equipment may establish Bluetooth communication or wireless communication connection.

[0046] In this embodiment, the aforementioned vehicle-mounted device or terminal device may be a portable terminal device that also includes other functions such as a personal digital assistant and / or music player, such as a mobile phone, tablet computer, or wearable terminal device with wireless communication capabilities (such as a smartwatch). Exemplary embodiments of the portable terminal device include, but are not limited to, portable terminal devices running iOS, Android, Microsoft, or other operating systems. The aforementioned portable terminal device may also be other portable terminal devices, such as a laptop computer.

[0047] As can be seen, in this embodiment, the terminal device responds to a media data control command triggered by the user for the first application and sends media data to the in-vehicle device. The in-vehicle device receives the media data sent by the terminal device, wherein the media data originates from the first application in the terminal device. The in-vehicle device sends the media data to the terminal device so that the second application on the terminal device generates projection data based on the media data. The terminal device receives the media data sent by the in-vehicle device, configures the media data according to the second application to generate corresponding projection data, and sends the projection data to the in-vehicle device. The in-vehicle device receives the projection data sent by the terminal device; based on the projection data and the media data, the in-vehicle device renders the target page corresponding to the first application in a preset page. In this way, terminal devices can avoid situations where they cannot control media data due to the inability of applications to obtain relevant data information. This enables terminal devices to control media data during cross-device screen mirroring, which is beneficial to improving user experience. Furthermore, the in-vehicle device can render media data based on the second application, thereby enabling screen mirroring of media data corresponding to the first application on the terminal device. Moreover, after establishing an audio transmission connection with the terminal device, the in-vehicle device can not only play the audio from the terminal device, but also obtain and display detailed audio information from the terminal device, making it convenient for users to obtain audio information and enhancing the richness of interactive content on the in-vehicle terminal.

[0048] Please see Figure 1B This is a flowchart illustrating an embodiment of an information processing method provided in this application. Applied to in-vehicle devices, in this embodiment the in-vehicle infotainment system (IVR) is a device installed inside a car. The IVR enables communication between people and the car, and between the car and the outside world. The terminal device is a mobile phone. The information processing method described in this embodiment includes the following steps:

[0049] 101. The vehicle-mounted device receives media data sent by the terminal device, wherein the media data originates from a first application in the terminal device.

[0050] The aforementioned vehicle-mounted equipment can communicate with terminal devices, specifically through Bluetooth, USB data transmission, or wireless network protocols.

[0051] The aforementioned first application is installed on the terminal device, and this first application may include audio applications. The aforementioned media data originates from this first application, and this media data may include the song being played, the song title, lyrics, the singer, etc., which are not limited here.

[0052] The in-vehicle device can receive a screen projection command from the terminal device after establishing a Bluetooth communication connection with the terminal device; and receive media data sent by the terminal device according to the Bluetooth data transmission channel corresponding to the Bluetooth communication connection.

[0053] 102. The vehicle-mounted device sends the media data to the terminal device, so that the second application on the terminal device generates screen projection data based on the media data.

[0054] 103. The vehicle-mounted device receives the screen projection data sent by the terminal device.

[0055] The second application, installed on the terminal device, differs from the first application and is primarily used for screen projection. In this embodiment, the second application is a vehicle-to-everything (V2X) application developed based on in-vehicle equipment, enabling data interaction between the terminal device and the in-vehicle equipment.

[0056] In this case, incompatibility may occur between the in-vehicle device and the terminal device due to differences in operating systems. That is, after media data from the first application is transmitted to the in-vehicle device, the in-vehicle device may not be able to perform the functions corresponding to the first application, such as music playback. Therefore, in this embodiment, the in-vehicle device receives the media data sent by the first application in the terminal device via a Bluetooth data transmission channel, and then sends the media data back to the second application in the terminal device. The second application analyzes the media data to obtain projection data, and then transmits the projection data and the media data to the in-vehicle device, so that the media data is displayed on the in-vehicle device's screen.

[0057] The aforementioned projection data is generated by the second application based on the aforementioned media data. The projection data includes rendering data, page layout rules, etc. The in-vehicle device generates a display interface based on the projection data and media data, so that the interactive interface of the in-vehicle device displays the aforementioned media data in the display mode of the second application.

[0058] 104. The in-vehicle device renders the target page corresponding to the first application in a preset page based on the screen projection data and the media data.

[0059] The preset page can be set by the user or be the system default; no specific limitation is made here. This preset page can be specified in the in-vehicle device, or it can be generated in real-time in the background after the in-vehicle device receives the screen mirroring command sent by the terminal device. This preset page can refer to the page preset in the in-vehicle device before screen mirroring is implemented based on the aforementioned screen mirroring data and media data.

[0060] The projection data includes rendering data, which includes at least one of the following: image rendering data, text rendering data, style rendering data, etc., without limitation.

[0061] Optionally, the specific data in each type of the above rendering data can be referred to as a rendering element. For example, image rendering data may include multiple rendering elements, such as foreground elements and background elements, where both foreground and background elements can be composed of RGB values. Similarly, text rendering data may include multiple rendering elements, such as multiple characters, each of which can be called a rendering element.

[0062] In specific implementation, the preset page may include multiple grids, each grid corresponding to a coordinate. Rendering the target page corresponding to the first application on the preset page may include the following steps: The in-vehicle device can select multiple target grids from the multiple grids on the preset page based on the aforementioned projection data, and group the multiple grids to obtain multiple grid sets, each grid set corresponding to a rendering element. Thus, the coordinates corresponding to the rendering data in each grid set can be determined, resulting in multiple coordinate sets, each coordinate set including at least one coordinate, each coordinate corresponding to a rendering element. Finally, based on different rendering elements, data corresponding to the rendering elements can be selected from the media data to obtain multiple target data, each target data corresponding to a rendering element. Then, based on each coordinate set, the corresponding target data can be filled into or adapted to the corresponding coordinates. Finally, the aforementioned target page can be generated. This enables the projection function, allowing projection of audio applications.

[0063] In one possible example, rendering the target page corresponding to the first application on a preset page based on the projection data and the media data may include the following steps: parsing the projection data to obtain page layout rules and rendering data, wherein the rendering data includes at least one of the following: image rendering data, text rendering data, and style rendering data; parsing the media data to obtain audio data and page display data corresponding to the second application; determining the mapping relationship between the page display data and the rendering data according to the page layout rules; and rendering the target page corresponding to the first application on the preset page based on the mapping relationship, the playback data, the page display data, and the rendering data.

[0064] The aforementioned rendering data includes at least one of the following: image rendering data, text rendering data, style rendering data, etc., which are not limited here.

[0065] The aforementioned media data may include audio data and page display data corresponding to the second application. Due to limitations in the display space of the in-vehicle device or preset page display rules (e.g., larger fonts or smaller display area on preset pages compared to the terminal device), when casting media data from the second application to the in-vehicle device, the media data can be filtered to select only the most important data for casting, thus obtaining the desired page display data.

[0066] The data displayed on the aforementioned page may include at least one of the following: song title, image data, artist, lyrics, etc., without limitation.

[0067] The audio data mentioned above is different from the data displayed on the page. The audio data can refer to digitized sound data, including sound characteristics such as pitch, melody, and rhythm.

[0068] In practical implementation, the aforementioned page layout rules can be used to plan the layout of a preset page to determine the page display data corresponding to each area, thereby obtaining the mapping relationship between the page display data and the rendering data. Based on the mapping relationship and the rendering data, the page display data is rendered on the preset page accordingly. Then, based on the playback data, the corresponding audio data in the current preset page can be determined. Finally, the target page can be obtained. In this way, the screen casting function for media data in the first application on the terminal device can be realized.

[0069] Optionally, the above method may further include the following steps: filtering the page display data according to the page layout rules to obtain the page display data corresponding to each area in the preset page; determining the maximum data display volume for each area in the preset page according to the page layout rules; if the data volume of the page display data i corresponding to area i is greater than or equal to the maximum data display volume corresponding to area i, then splitting the page display data to obtain multiple sub-page display data, and rotating the multiple sub-page display data in area i at a preset speed, preset period, and preset switching method, wherein area i is one of the areas corresponding to the preset page.

[0070] In this embodiment of the application, if lyrics need to be played but the page area for displaying the lyrics is small, the lyrics can be split into multiple sub-lyrics and dynamically displayed in a carousel manner. In this way, dynamic playback of page display data such as lyrics can be achieved according to the preset page space and page display rules, which is beneficial to improving the user experience.

[0071] Optionally, after rendering the target page corresponding to the first application in the preset page, the above method may further include the following steps: in response to a control command triggered by a user on the target page, identifying the control command; if the control command is a first control command, controlling the target page; if the control command is a second control command, sending the control command to the terminal device, receiving target media data sent by the terminal device, and updating the target page according to the target media data. When a user triggers a control command on the target page, the control command is sent to a second application. After identifying the control command, the second application generates a corresponding execution command and sends the execution command to the in-vehicle device. After receiving the execution command, the in-vehicle device sends the execution command to the first application in the terminal device via a Bluetooth data transmission channel. The first application receives the execution command and processes the corresponding events according to the execution command.

[0072] Users can operate the terminal device to control the playback, switching, display, volume adjustment, and other functions of songs on the target page of the in-vehicle device.

[0073] The first control instruction differs from the second control instruction. The first control instruction can be used to control the page and does not require updating media data to achieve page control; for example, the first control instruction may include functions such as playing or pausing a song. The second control instruction can be used to control the page, but requires updating media data after page control to achieve page control; for example, the second control instruction may include switching to the next or previous song.

[0074] The aforementioned control commands include any one of the following: play song command, switch song command, pause song command, and volume control command. Of course, other control commands may also be included, which are not limited here.

[0075] As can be seen, in the embodiments of this application, it is possible to determine whether media data needs to be updated for different control commands in order to realize the control function corresponding to the control command.

[0076] Furthermore, since the two applications on the terminal device cannot access each other's data, if the aforementioned control command is a second control command, the target media data can be sent to the second application on the terminal device. Then, the terminal device can reconfigure the corresponding screen projection data for the in-vehicle device based on the target media data to obtain the target screen projection data, and send this target screen projection data to the in-vehicle device. The in-vehicle device can update the target page based on the target screen projection data to respond to the second control command. Thus, in this embodiment, the inability to control media data due to the inability of applications on the terminal device to obtain relevant data information can be avoided. This allows the terminal device to meet the control needs for media data (such as switching to the next or previous song) during screen projection, thereby improving the user experience.

[0077] As can be seen, the information processing method provided in this application, when applied to an in-vehicle device, receives media data sent by a terminal device, wherein the media data originates from a first application in the terminal device; sends the media data to the terminal device so that a second application on the terminal device generates projection data based on the media data; receives the projection data sent by the terminal device; and renders the target page corresponding to the first application in a preset page based on the projection data and the media data. Thus, the rendering of media data can be achieved based on the second application, thereby enabling the projection of media data corresponding to the first application in the terminal device.

[0078] In other embodiments, the second application may draw the image to be projected based on the media data. The image to be projected is the target page corresponding to the first application. The image to be projected is transmitted to the vehicle device as projection data via the Bluetooth data transmission channel. The vehicle device receives the projection data, forms the image, and displays it on the vehicle device display screen.

[0079] Consistent with the above, please refer to Figure 2 This is a schematic flowchart of an embodiment of an information processing method provided in this application. The information processing method described in this embodiment is applied to a terminal device, which is connected to an in-vehicle device for screen projection. The terminal device includes a first application and a second application, and includes the following steps:

[0080] 201. The terminal device responds to the media data control command triggered by the user for the first application and sends the media data to the vehicle-mounted device.

[0081] 202. The terminal device receives the media data sent by the vehicle-mounted device.

[0082] 203. The terminal device configures the media data according to the second application to generate corresponding screen projection data.

[0083] 204. The terminal device sends the projection data to the vehicle-mounted device.

[0084] The first application and the second application are different. The first application may refer to an audio application APP, and the second application can be used to draw or configure the projection data of the media data corresponding to the first application. The projection data may include rendering data, page layout rules, etc. The rendering data can be used to display the media data on the terminal device.

[0085] In this application, the user can initiate a media data control command in the second application of the terminal device. This media data control command can be used to project the screen onto the in-vehicle device. Furthermore, a communication connection can be established between the terminal device and the in-vehicle device via Bluetooth, and the media data corresponding to the media data control command can be sent to the in-vehicle device.

[0086] Since the two applications on the terminal device cannot obtain specific data, meaning the second application cannot communicate with the first application, media data can be sent to the in-vehicle device and then transmitted to the second application on the terminal device. However, because the terminal device and the in-vehicle device are incompatible, the in-vehicle device cannot render the media data to obtain the rendered target page. Therefore, the second application can configure the corresponding preset page on the in-vehicle device to obtain projection data for media rendering on the in-vehicle device. This projection data can then be sent to the in-vehicle device, which can further process cross-terminal information based on it.

[0087] In one possible example, configuring the screen casting data corresponding to the media data according to the second application may include the following steps: obtaining a preset mapping relationship between applications and screen casting data; and determining the screen casting data corresponding to the second application based on the mapping relationship.

[0088] The terminal device can store a preset mapping relationship between applications and screen projection data. This application can be not limited to audio apps, but can also be a video app. In specific implementation, the mapping relationship between applications and screen projection data can be determined based on the relationship between different applications and the configuration parameters of the vehicle device (e.g., display size, display name, display kernel type, operating system corresponding to the display, etc.). In this way, screen projection data adapted to the vehicle device can be configured.

[0089] The mapping relationship described above can be set by the user or by the system default, and is not limited here. Users can set page layout rules for the first application in the second application, or they can directly design the page UI in the second application. Then, when casting the first application to the in-vehicle device, the media data can be rendered according to the user-designed page layout rules to achieve cross-terminal casting. In this way, users can configure it according to their preferences, which helps improve the user experience.

[0090] As can be seen, the information processing method provided in this application, when applied to a terminal device, responds to a media data control command triggered by a user for a first application, sending the media data to the in-vehicle device; receiving the media data sent by the in-vehicle device; configuring the media data according to a second application to generate corresponding projection data; and sending the projection data to the in-vehicle device. This avoids the situation where control over media data cannot be achieved due to the inability of applications in the terminal device to obtain relevant data information, and enables the terminal device to meet the control needs for media data during cross-device projection, thus improving the user experience.

[0091] Consistent with the above, please refer to Figure 3A This is a schematic flowchart of an embodiment of an information processing method provided in this application. The information processing method described in this embodiment includes the following steps:

[0092] 301. The terminal device responds to the media data control command triggered by the user for the first application and sends the media data to the vehicle-mounted device.

[0093] 302. The vehicle-mounted device receives media data sent by the terminal device, wherein the media data originates from a first application in the terminal device.

[0094] 303. The vehicle-mounted device sends the media data to the terminal device, so that the second application on the terminal device generates screen projection data based on the media data.

[0095] 304. The terminal device receives the media data sent by the vehicle-mounted device.

[0096] 305. The terminal device configures the media data according to the second application to generate corresponding screen projection data.

[0097] 306. The terminal device sends the screen projection data to the vehicle-mounted device.

[0098] 307. The vehicle-mounted device receives the screen projection data sent by the terminal device.

[0099] 308. The in-vehicle device renders the target page corresponding to the first application in a preset page based on the projection data and the media data.

[0100] For a detailed description of step 301 above, please refer to Figure 2 The corresponding steps of step 201 in the described information processing method, and the detailed descriptions of steps 302-303 above, can be found in [reference needed]. Figure 1B The corresponding steps of steps 101-102 in the described information processing method, and the detailed descriptions of steps 304-306 above, can be found in [reference needed]. Figure 2 The corresponding steps 202-205 of the described information processing method, and the detailed descriptions of steps 307-308 above, can be found in [reference needed]. Figure 1B The corresponding steps of steps 103-104 of the described information processing method will not be repeated here.

[0101] For example, please refer to Figure 3B , Figure 3B This is an interactive schematic diagram of an information processing method provided in this application embodiment. As shown in the figure, the user can select whether to display the first information processing on the in-vehicle device in the application interface corresponding to the first application. If the user selects "yes", the media data can be sent to the in-vehicle device via Bluetooth. For example, if the song currently being played by the first application is "Me and My Motherland", then the media data related to the song (e.g., song name, audio data, singer, lyrics, etc.) can be sent to the in-vehicle device. After receiving the media data, the in-vehicle device can send the media data to the second application in the terminal device. The second application can configure the projection data adapted to the display of the in-vehicle device based on the media data, such as rendering data and page layout rules. Furthermore, the in-vehicle device can further render a preset page based on the media data and projection data to obtain a target page. The target page can display the media data and play the audio data through the audio output device corresponding to the in-vehicle device.

[0102] As can be seen, through the information processing method provided in this application embodiment, the terminal device responds to a media data control command triggered by the user for the first application and sends media data to the in-vehicle device. The in-vehicle device receives the media data sent by the terminal device, wherein the media data originates from the first application in the terminal device. The in-vehicle device sends the media data to the terminal device so that the second application on the terminal device generates projection data based on the media data. The terminal device receives the media data sent by the in-vehicle device, configures the media data according to the second application to generate corresponding projection data, and sends the projection data to the in-vehicle device. The in-vehicle device receives the projection data sent by the terminal device; based on the projection data and the media data, the in-vehicle device renders the target page corresponding to the first application in a preset page. In this way, terminal devices can avoid situations where they cannot control media data due to the inability of applications to obtain relevant data information. This enables terminal devices to control media data during cross-device screen mirroring, which is beneficial to improving user experience. Furthermore, the in-vehicle device can render media data based on the second application, thereby enabling screen mirroring of media data corresponding to the first application on the terminal device.
