The vehicle system can control the display component to display key information. And after the vehicle-mounted system displays the key information on the display component so as to realize that a user executes preset control processing on the key information, the terminal equipment executes corresponding operation corresponding to the corresponding preset control processing. In some application scenarios, the preset control process may be operations such as playing music, pausing music, and the like. In some application scenarios, the display of the key information by the vehicle system control display component may be displaying key information (ID 3 information) corresponding to music data. In some application scenarios, the preset processing performed by the user on the displayed key information may be preset processing of playing music performed by the vehicle-mounted system on the displayed key information (ID 3 information), which may enable the control terminal Device (Apple Device) to perform an operation corresponding to the corresponding playing music. In some application scenarios, the preset process performed by the user on the displayed key information may be a pause music preset process performed by the vehicle-mounted system on the displayed key information (ID 3 information), and it may be realized that the terminal Device (Apple Device) is controlled to perform an operation corresponding to the corresponding pause music.

Exemplary, as shown in fig. 2, fig. 2 is a schematic structural diagram of interaction between a terminal device and a display component in an embodiment of a data display method of the present application.

And the vehicle-mounted system analyzes and processes the media data to obtain key information corresponding to the media data. And the vehicle-machine interconnection service assembly in the vehicle-machine system receives the key information and stores the key information into the vehicle-machine interconnection service assembly. The vehicle-to-machine interconnection service component can be connected with a display component in the vehicle-to-machine system. The vehicle-mounted system can send the key information to the media client and/or the instrument panel in the display component through the vehicle-mounted interconnection service component. The vehicle system can control the display component to display the key information. It can be considered that the key information is stored in the vehicle-to-machine interconnection service component, and at this time, the vehicle-to-machine interconnection service component can be a database capable of storing the key information. In particular, the vehicle-to-machine interconnection service component may be a list or database that holds audio files or video files. The vehicle-computer interconnection service component in the vehicle-computer system can be a transfer component between the terminal equipment and the display component, the vehicle-computer system stores the key information after the analysis of the media data in the transfer component, and the vehicle-computer system can forward the key information to the media client and/or the instrument panel in the display component through the vehicle-computer interconnection service component, so that the subsequent control of the display component to display the key information is facilitated.

It is understood that the information displayed by the vehicle system at the display assembly or the information contained in the displayed user interface may be media information. In some application scenarios, the media information may be at least part of the key information. In some application scenarios, the media information may be media data. In some application scenarios, the media information may be integrated information obtained by integrating at least part of the key information and the media data after a preset process.

In some embodiments, the step S12 may include the following steps: firstly, format conversion is carried out on media data by using a vehicle-machine interconnection plug-in service to obtain conversion data supported by a vehicle-machine interconnection service component. And secondly, calling a service implementation interface in the vehicle machine protocol service, and loading the conversion data into a service implementation class. And then, analyzing the converted data by using the service realization class to obtain the key information of the media data.

In some application scenarios, the vehicle-to-machine interconnection plug-in service may perform format conversion on the received data to obtain a data format or a data type corresponding to the converted data set according to the preset requirement. In some application scenarios, the vehicle-to-machine interconnection plug-in service may perform format conversion on the received data, so as to obtain a data format or a data type corresponding to the converted data supported by the vehicle-to-machine interconnection service component. In some application scenarios, the on-board interconnect plug-in service may be a service (CarPlayPluginService) that interfaces with the apple SDK. Apple SDK (Software Development Kit) is a set of development tools and frameworks provided by apple corporation for building and developing applications based on the apple operating system (e.g., iOS, iPadOS, macOS and watch os). In some application scenarios, a TCP/IP network protocol stack may be created between the terminal device and the in-vehicle interconnect plug-in service. The vehicle-mounted interconnection plug-in service can read media data sent to terminal equipment (Apple Device) through a network protocol stack (TCP/IP).

The vehicle-mounted interconnection plug-in service receives the call back created by the communication session, and simultaneously creates a read-write channel from the vehicle-mounted interconnection plug-in service to the vehicle-mounted protocol service. The communication session may be a CarPlay session. The CarPlay session may refer to a communication session established between a car machine system (CarPlay system) and a terminal Device (Apple Device). The vehicle-mounted protocol service can be a component or a functional module capable of carrying out data analysis processing in the vehicle-mounted system. In some application scenarios, the in-vehicle protocol service may be an exchange data protocol service (iapsiervice). The vehicle-mounted protocol service can analyze and process the media data sent by the vehicle-mounted interconnection plug-in service after passing through the read-write channel. After the vehicle-mounted protocol service receives the media data, the vehicle-mounted system can call a service implementation interface (hidl interface) in the vehicle-mounted protocol service to load the media information into a service implementation class (impl implementation class) in the vehicle-mounted protocol service. The service implementation class can be a specific functional module capable of realizing information analysis processing in the vehicle-to-machine protocol service. The number of service implementation classes may be multiple. In some application scenarios, the service implementation class may be a service implementation class (impl implementation class) in a car set protocol service. And the vehicle-mounted system analyzes and processes the media data by utilizing the service implementation class to obtain the key information.

Exemplary, as shown in fig. 3, fig. 3 is a schematic structural diagram of interaction between a terminal device and a vehicle-to-machine interconnection service component in an embodiment of the data display method of the present application. Firstly, the vehicle-mounted system analyzes and processes the media data, and the step of obtaining key information of the media data can be realized by using vehicle-mounted interconnection plug-in services and vehicle-mounted protocol services between the terminal equipment and the vehicle-mounted interconnection service component. A TCP/IP network protocol stack channel can exist between the terminal equipment and the vehicle-machine interconnection plug-in service, and a read-write channel can exist between the vehicle-machine interconnection plug-in service and the vehicle-machine protocol service. It can be appreciated that the read-write channel described above may implement the transmission of IAP data. And the terminal equipment sends the media data to the interconnection plug-in service of the vehicle-to-vehicle machine through a TCP/IP network protocol stack channel. And carrying out format conversion processing on the received media data by using the vehicle-to-machine interconnection plug-in service to obtain conversion data, wherein the conversion data can be supported or compatible by a vehicle-to-machine interconnection service component. The vehicle-mounted interconnection plug-in service can send the conversion data to the vehicle-mounted protocol service through the read-write channel. The vehicle-mounted system can call a service implementation interface in the vehicle-mounted protocol service and load the conversion data into a service implementation class in the vehicle-mounted protocol service. And analyzing the converted data by using the service realization class to obtain key information of the media data. The key information can be transmitted to the vehicle-to-vehicle interconnection service component by the following vehicle-to-vehicle system, and the key information is stored in the vehicle-to-vehicle interconnection service component.

It can be considered that the interaction of the interconnected media data in the display assembly can be improved by utilizing the vehicle-to-vehicle interconnection plug-in service and the vehicle-to-vehicle protocol service between the terminal equipment and the vehicle-to-vehicle interconnection service assembly to analyze the media data into key information.

In some embodiments, the number of key information is a plurality, and the step S13 may include the following steps: first, a connection between a media browser service in the interconnected service component of the vehicle machine and a media browser in the media client is established. The control media session then sends at least part of the critical information to the media controller of the media client.

The media browser service may be a functional module in the vehicle-to-machine interconnection service component that is capable of connection and data interaction with the media client. In some application scenarios, the media browser service may be a mediabrowser service. In some application scenarios, the media browser service may be a service inherited from mediabrowser service in the vehicle-to-machine interconnection service component, and illustratively, the media browser service may be a carryover mediabrowser service inherited from mediabrowser service in the vehicle-to-machine interconnection service component. It is understood that the media browser service in the vehicle-to-machine interconnection service component may be a server. The media client may be a functional module in the media client that is capable of connecting and data interaction with a media browser service of the vehicle-to-machine interconnection service component. In some application scenarios, the media browser may be a MediaBrowser media browser. In some application scenarios, the media browser may be inherited from MediaBrowser in the media client. It may be appreciated that the media browser in the vehicle-to-machine interconnection service component may be a client corresponding to a server in the vehicle-to-machine interconnection service component.

And establishing connection between the media browser service in the interconnection service component of the vehicle machine and the media browser in the media client. The connection between the server and the client can be established by the vehicle-mounted system, or the pairing between the server and the client can be completed. In some application scenarios, based on the connection between the media browser service and the media browser in the media client, since the client and the server are in asynchronous communication, a large number of callbacks are employed, and thus there are a large number of callbacks between the server and the client.

The control media session sends at least part of the critical information to the media controller of the media client. The media session may be a session service class in a service end corresponding to the vehicle-machine interconnection service. In some application scenarios, the media session may be a MediaSession media session. The media session may be a session for managing audio playback and media control. The media session may provide a standardized way for the media client to interact with media controls, audio focus management, media metadata and status updates, audio buttons and notification controls, and management notification bars, etc., providing a better audio playback experience. In some application scenarios, a media session may be used for media control, through which a media session a media client may send various media control commands, such as play, pause, next, last, etc., to control the media being played. In some application scenarios, a media session may be used for audio focus management, through MediaSession, an application may request and manage audio focus. Audio focus is a mechanism for controlling audio priority and coordination among multiple applications to ensure that the most appropriate application obtains audio output rights. In some application scenarios, media sessions may be used for media metadata and status updates, with MediaSession allowing applications to update metadata information of the media, such as song title, artist, album art, etc. It may also provide current play status, such as play, pause, stop, etc., so that other components (e.g., notification bars, lock screen controls, etc.) may be updated in time. In some application scenarios, a media session may be used for audio buttons and notification control, through which an application may handle hardware key events associated with audio, such as a play pause key on a headset. Meanwhile, the media session can also manage the media control panel in the notification bar, so that the user can conveniently control the playing and suspending of the media from the notification bar.

The media controller of the media client may be a media control class of the media client capable of performing data interaction with the session service class of the server. The media controller may also be a class for controlling the operation of the media player and displaying the views of the media controller. In some application scenarios, the media controller of the media client may be a MediaController media controller. The media controller may be used to control the operation of the media player and display the media controller view. In some application scenarios, a media controller may provide a set of methods and callbacks for managing media playback, media control, and interactions. In some application scenarios, the media controller may be used for media control, and MediaController provides a set of media control methods, such as play, pause, fast forward, fast reverse, last song, next song, etc., that can conveniently control the operation of the media player. In some application scenarios, a media controller may be used to display a media controller view, and a MediaController may be associated with a media player view (e.g., videoView, mediaPlayer, etc.) and display the media controller view, including a play/pause button, a progress bar, a time display, etc. The user may control the media playback by interacting with the media controller view. In some application scenarios, the media controller may be used to update the play status and progress, and the MediaController may update the display of the media controller view according to the status and progress of the media player. For example, when the media player begins playing or pausing, the MediaController may update the state of the play/pause button; when the media play progress changes, it may update the progress bar and the time display. In some application scenarios, the media controller may be configured to respond to media control events, and the MediaController may monitor the media control events, such as clicking a play button, dragging a progress bar, etc., and respond to those events by callback methods. The developer may implement custom operations in the callback method, such as updating the state of the media player, handling state changes of the player, etc.

The in-car system may control the media session to deliver at least a portion of the critical information to a media controller that is sent to the media client. At least some of the key information in the in-car system may generate a session that manages audio playback and media control. It will be appreciated that the media session in the vehicle system provides a unified interface for managing audio playback and media control related sessions. The media session may simplify interactions between the media client (i.e., a local application in the in-car system) and system audio and media management and provide better user experience and control capabilities. The media controller may simplify control and interaction of the media player, providing a set of callbacks to control and manage media playback.

Exemplary, as shown in fig. 4, fig. 4 is a schematic structural diagram of interaction between a vehicle-to-machine interconnection service component and a display component in an embodiment of a data display method according to the present application. The step of sending the key information to the display component in the vehicle-mounted system based on the connection between the display component in the vehicle-mounted system and the vehicle-mounted interconnection service component can be realized by using a media browser service, a media session, a media browser and a media controller. First, a media browser service in the vehicle-to-machine interconnection service component establishes a connection or completes pairing with a media browser in the media client. And secondly, using a media browser service (CarplayMediaBrowservice) interface in the vehicle-to-machine interconnection service component, the vehicle-to-machine system can set part of key information for the media client. The vehicle system can set part of key information to the media session through a media browser service interface. It will be appreciated that taking media data as an example of music data, the setting of part of the key information to the media session at this time may be part of the music information, such as the cover, name, lyrics, etc. of a song. The media session may then send a portion of the critical information to a media controller in the media client. The step of sending part of the key information to the media controller in the media client by the media session may be two modes of predefined callbacks corresponding to standard player operations (play, pause, stop, etc.), and extensible custom calls for defining special behaviors unique to the application, so as to achieve intercommunication between the media session and the media controller.

It may be considered that the transmission of part of key information between the vehicle-mounted interconnection service component and the media client is achieved through the media browser service, the media session, the media browser and the media controller, at this time, the vehicle-mounted interconnection service component may be responsible for providing key information corresponding to the media data, without directly processing control operations (such as playing, suspending, stopping, etc.), and the vehicle-mounted interconnection service component acts as a provider and manager of the media data and may improve interaction of the interconnected media data in the display component.

In some embodiments, the step S14 may include the following steps: first, current information of the media controller is updated based on at least part of the key information in the media controller. Then, in response to receiving a selection instruction for the media controller, current information of the media controller is displayed on a display interface.

The media controller may receive at least a portion of the critical information communicated by the media session. The current information of the media controller is updated based on at least a portion of the key information in the media controller. Prior to updating, the current information of the media controller may be interface information native to the local application in the media client. The current information of the media controller may be plural. In some application scenarios, the current information of the media controller may be that the user interface control (UI control) is a commonly used element in user interface design for exposing and receiving the interaction of the car machine system with the user. The vehicle system can generate interaction information corresponding to the user interface based on at least part of the key information. Updating the current information of the media controller based on at least a portion of the key information in the media controller may be updating a user interface control (UI control) based on the interactive information in the in-car system.
