Description

Technical Field

[0001] The present invention relates to the technical field of vehicle networking, and in particular to a vehicle-mounted media playback control method. Background Art

[0002] With the development of Internet of Vehicles technology, human-computer interaction in vehicles is undergoing unprecedented innovation. In order to cater to the growing demand for personalization, vehicle manufacturers have invested a lot of resources to improve the interactive experience in the car. The number of car screens has increased significantly, and each screen carries an independent functional module, designed to provide customized services for passengers in different seats. In this way, both the driver and the rear seat passengers can freely select and control the corresponding screen according to their preferences, enjoy a variety of entertainment and information content, and greatly enrich the riding experience.

[0003] Although the multi-screen configuration solves the problem of personalized distribution of visual content, it still has shortcomings in audio output. Specifically, in a scenario where multiple passengers are sharing a ride, the auditory needs of each passenger are often very different: the driver may pay more attention to navigation instructions and background music, while the backseat passengers may prefer to watch movies or play games. Due to the relatively closed space inside the car, interference between different audio sources has become an issue that cannot be ignored. In some technical solutions, the vehicle uses a single audio output channel, and all sound signals are played through the vehicle's built-in speakers, lacking an effective audio isolation mechanism. This design not only fails to meet passengers' personalized pursuit of audio experience, but also easily causes sound confusion, reduces the overall listening quality, and thus affects the overall satisfaction of human-computer interaction. Summary of the invention

[0004] The problem solved by the present invention is how to separate and output audio and video data streams.

[0005] To solve the above problems, in a first aspect, the present invention provides a method for controlling in-vehicle media playback, which is applied to an in-vehicle terminal, wherein the in-vehicle terminal includes at least two terminal devices, and the terminal devices are used to receive a data stream from a corresponding virtual space in a cloud vehicle server; the method includes:

[0007] Sending the extended output signal to the cloud vehicle machine server, so that the cloud vehicle machine server determines the corresponding first virtual space according to the extended output signal;

[0008] receiving a first data stream generated from the first virtual space;

[0009] The first data stream is output in the extended output device through the first communication link.

[0010] Compared with the prior art, when the vehicle terminal detects the extended output signal, the first terminal device to which the extended output device is to be connected is determined according to the preset strategy, so as to prevent the problem of device connection confusion when the vehicle has multiple terminal devices. After successfully connecting to the extended output device, the extended output signal is sent to the cloud car machine server, the first virtual space corresponding to the extended output signal is determined, and a data stream is generated through the cloud to reduce the computing power burden of the vehicle terminal. The first virtual space is determined according to the extended signal to prevent the problem of stream confusion when the cloud pushes the stream. After receiving the first data stream, the first data stream is transmitted to the extended output device through the first communication link, and the first data stream is played. The cloud is used to share the computing power burden of the vehicle terminal, and the first terminal device and the corresponding first virtual space are determined according to the extended output signal generated by the extended output device. The data stream is directed through the first virtual space and forwarded through the first communication link to ensure the separate push and separate playback of the data stream. In the multi-terminal device scenario, the audio and video data to be played by different terminal devices can also be separated and output, thereby improving the satisfaction of human-computer interaction.

[0044] In view of the problems existing in the above-mentioned related technologies, this embodiment provides a method for controlling vehicle-mounted media playback.

[0045] like Figure 1 and Figure 3 As shown, in the first aspect, an embodiment of the present invention provides a method for controlling in-vehicle media playback, which is applied to an in-vehicle terminal, wherein the in-vehicle terminal includes at least two terminal devices, and the terminal devices are used to receive a data stream from a corresponding virtual space in a cloud vehicle server; the method includes:

[0046] Step S100, in response to an extended output signal generated by an extended output device, determining a first terminal device to which the extended output device is to be connected according to a preset strategy, and establishing a first communication link, wherein the first communication link is used to connect the extended output device and the first terminal device.

[0047] Specifically, the vehicle-mounted terminal referred to in the embodiment of the present invention includes a collection of vehicle-mounted equipment inside the vehicle, and the terminal equipment includes a vehicle-mounted equipment with independent functions, such as a vehicle-mounted equipment screen that can independently provide services, a central control screen, or a main driving screen with independent service capabilities.

[0048] Specifically, the extended output devices include external devices with audio and video output functions, such as headphones, speakers and other devices with audio output functions; or monitors, computers and other devices with video output functions; or other devices with both audio and video output functions, such as virtual reality devices, projection devices, etc.

[0049] In one embodiment, the extended output device includes an audio output device such as a Bluetooth headset and a Bluetooth speaker. When the Bluetooth headset is connected to the vehicle computer, an extended output signal is generated to connect to a terminal device in the vehicle according to a preset strategy to establish a first communication link. In this embodiment, the Bluetooth headset is connected to the first terminal device and an extended output signal is generated, and the first communication link is a Bluetooth link. The audio stream is pushed from the first terminal device to the Bluetooth headset through the Bluetooth link, and the Bluetooth headset outputs the audio.

[0050] In another embodiment, the extended output device includes a wired audio output device such as a wired headset. When the wired headset is connected to the vehicle computer, an extended output signal is generated and a first communication link is established. The first communication link includes a physical transmission link based on an electrical signal.

[0051] In one embodiment, since there are multiple terminal devices inside the vehicle, when the extended output device generates an extended output signal, in order to avoid confusion in the connection between the extended output device and the terminal device, the terminal device connected to the extended output device is determined by a preset strategy, and the preset strategy includes determining the terminal device connected to the extended output device according to the user setting. For example, the user actively sets the Bluetooth headset 1 to correspond to the terminal device corresponding to the co-pilot, and sets the Bluetooth headset 2 to correspond to the terminal device corresponding to the left rear seat. Then, when the Bluetooth headset 1 is used as the extended output device, the terminal device corresponding to the co-pilot is used as the first terminal device. For another example, when the extended output device is a wired headset 1, if the user actively sets the wired headset 1 to correspond to the terminal device corresponding to the co-pilot, then even if the wired headset 1 is plugged into the jack of other terminal devices, the headset will output the audio of the terminal device corresponding to the co-pilot.

[0052] Step S200, sending the extended output signal to the cloud vehicle machine server, so that the cloud vehicle machine server determines the corresponding first virtual space according to the extended output signal.

[0053] Specifically, in order to reduce the computing power burden of the terminal device, a cloud car machine server with an in-vehicle application generates a data stream and pushes it to the terminal device. The terminal device assumes the functions of logging into the cloud car machine, receiving the push stream of the corresponding instance resource, playing the data stream and local storage according to actual needs. Therefore, after the extended output device generates an extended output signal and connects with the first terminal device, it is necessary to push the separated audio and video data stream to the first terminal device through the cloud car machine server, and then separate the audio and video output through the first terminal device. Sending an extended output signal to the cloud car machine server is used to enable the instance resource to determine the separated audio and video data stream to be generated, that is, to determine the first virtual space corresponding to the first terminal device, and use the data stream generated by the first virtual space as the first data stream to achieve the separated output of the data stream.

[0054] The virtual space referred to in the embodiment of the present invention includes a plurality of independent computing resource sets created by one of the instance resources of the cloud vehicle machine server. Each virtual space has an independently run vehicle application. Optionally, the virtual space includes a virtual machine.

[0055] Step S300: receiving a first data stream generated from the first virtual space.

[0056] In one embodiment, after the vehicle terminal logs in to the cloud vehicle server, it is connected to the vehicle terminal through the instance resources in the cloud vehicle server. The instance resources have virtual spaces corresponding to the number of terminal devices and are connected accordingly. For example, if the vehicle terminal includes three terminal devices, then the instance resources have three virtual spaces. Terminal device 1 is connected to virtual space 1 to receive data streams from virtual space 1. Correspondingly, terminal device 2 is connected to virtual space 2, and terminal device 3 is connected to virtual space 3. In this embodiment, the first virtual space directly pushes the first data stream to the first terminal device.

[0057] In another embodiment, after the cloud vehicle server determines the first virtual space corresponding to the first terminal device, it sends the data stream generated by the first virtual space as the first data stream to the vehicle terminal, and then the vehicle terminal distributes the data stream to the corresponding first terminal device.

[0058] Step S400: output the first data stream in the extended output device through the first communication link.

[0059] In one embodiment, after the first data stream is pushed to the first terminal device, the data in the first data stream that can be output by the extended output device is transmitted to the extended output device through the first communication link, and is output by the extended output device. For example, when the extended output device is an audio output device, the audio data in the first data stream is transmitted to the device, and the audio data is output by the device; when the extended output device is a video output device, the video data in the first data stream is transmitted to the device, and the video data is output by the device.

[0060] In this embodiment, when the vehicle terminal detects the extended output signal, the first terminal device to which the extended output device is to be connected is determined according to a preset strategy to prevent the problem of device connection confusion when the vehicle has multiple terminal devices. After successfully connecting to the extended output device, the extended output signal is sent to the cloud car server to determine the first virtual space corresponding to the extended output signal, and a data stream is generated through the cloud to reduce the computing power burden of the vehicle terminal. The first virtual space is determined according to the extended signal to prevent the problem of stream confusion when the cloud pushes the stream. After receiving the first data stream, the first data stream is transmitted to the extended output device through the first communication link, and the first data stream is played. The cloud is used to share the computing power burden of the vehicle terminal, and the first terminal device and the corresponding first virtual space are determined according to the extended output signal generated by the extended output device. The data stream is directed through the first virtual space and forwarded through the first communication link to ensure the separate push and separate playback of the data stream. In the multi-terminal device scenario, the audio and video data to be played by different terminal devices can also be separated and output, which improves the satisfaction of human-computer interaction.

[0061] Optionally, the determining, according to a preset policy, a first terminal device to be connected to the extended output device comprises:

[0062] When at least two of the terminal devices receive data streams from different virtual spaces respectively, determining whether there is a preset configuration rule;

[0063] If the configuration rule exists, the first terminal device is determined according to the configuration rule.

[0064] Specifically, when there are at least two terminal devices playing different multimedia in the car at the same time, that is, at least two terminal devices receive data streams from different virtual spaces respectively, the first terminal device is determined according to the preset configuration rule. For example, when terminal device 1 receives a data stream from virtual space 1 and terminal device 2 receives a data stream from virtual space 2, if the extended output device generates an extended output signal, the corresponding connected terminal device needs to be determined to prevent connection confusion. It is determined whether there is a preset configuration rule to specify the first terminal device.

[0065] In one embodiment, the preset configuration rules include configuration rules set by the user, for example, determining the first terminal device to be connected according to the type of the extended output device, examples including: when the extended output device is a Bluetooth device, connecting terminal device 1; when the extended output device is a wired device, using terminal device 2 as the first terminal device / using the terminal device directly connected to the wired device as the first terminal device.

[0066] In another embodiment, the preset configuration rules include determining the first terminal device according to the number of terminal devices that are receiving the data stream. For example, when the number of terminal devices that are receiving the data stream is 1, that is, only one terminal device receives the push stream from the cloud car server, the terminal device is used as the first terminal device; when the number of terminal devices that are receiving the data stream is greater than or equal to 2, that is, there are multiple terminal devices receiving push streams from different virtual spaces of the cloud car server, the first terminal device is determined according to the configuration priority rules set by the user. For example, the configuration rule set by the user is to give priority to the terminal device corresponding to the co-pilot as the first terminal device of the extended output device; when the terminal device corresponding to the co-pilot does not receive the push stream, the terminal device corresponding to the left rear seat is used as the first terminal device.

[0067] Optionally, after determining whether a preset configuration rule exists, the method further includes:

[0068] If the configuration rule does not exist, the terminal device closest to the extended output device is used as the first terminal device.

[0069] In one embodiment, the user may not set a preset rule, and the origination position of the extended output signal is determined, and the terminal device closest to the extended output signal is used as the first terminal device. For example, when the extended output device is a Bluetooth device, the terminal device closest to the Bluetooth connection signal is used as the first terminal device; when the extended output device is a wired device, the terminal device that detects the wired device input signal is used as the first terminal device.

[0070] Optionally, the determining, according to a preset strategy, the first terminal device to be connected to the extended output device further comprises:

[0071] When at least two of the terminal devices in the vehicle output the first data stream, the main terminal device is used as the first terminal device, wherein the main terminal device includes a terminal device that directly receives the first data stream.

[0072] In one embodiment, when there are multiple terminal devices in the car that output the same data stream, there is only one terminal device directly connected to the virtual space of the cloud car server. The data stream is output to the remaining terminal devices through a copy screen or other technology. The main terminal device directly connected to the first virtual space is determined as the first terminal device, and the first data stream is forwarded to the extended output device through the first communication link.

[0073] Optionally, the in-vehicle media playback control method further includes:

[0074] When there is a second terminal device outputting a second data stream, the second data stream is output through an audio output device in the vehicle, wherein the second data stream comes from a second virtual space.

[0075] The audio output devices in the car include audio playback devices including power amplifiers (AMP).

[0076] In one embodiment, since the same instance resource can be divided into multiple virtual spaces, each virtual space can push a data stream to a corresponding terminal device. When a second terminal device is in the car to receive the second data stream, the second data stream is output through the audio output device in the car to ensure that the first data stream and the second data stream are played independently. For example, when the second terminal device receives the second data stream, the second terminal device is not connected to an extended output device, then the video stream in the second data stream is played through the second terminal device, and the second audio stream in the second data stream is played through the power amplifier (AMP) in the car. When a third terminal device is in the car to receive a third data stream, if there is no extended output device connected to the third terminal device, the third video stream in the third data stream is output through the third terminal device, and the third audio stream is played simultaneously through the power amplifier in the car.

[0077] Optionally, after determining the first terminal device to be connected to the extended output device according to a preset strategy in response to the extended output signal generated by the extended output device and establishing the first communication link, the method further includes:

[0078] In response to a disconnection signal generated by the extended output device, it is determined whether the second data stream exists.

[0079] When the second data stream does not exist, the audio output device is controlled to output a first audio stream, wherein the first data stream includes the first audio stream.

[0080] In one embodiment, when the extended output device is disconnected, since the first audio stream loses its playback channel, it is necessary to determine whether there are other terminal devices in the car that receive the data stream. When there is no second terminal device that receives the second data stream, the first audio stream is played with the help of the audio output device in the car.

[0081] Alternatively, if Figure 4 As shown, after determining whether the second data stream exists in response to the disconnection signal generated by the extended output device, the method further includes:

[0082] When the second data stream exists, the audio output device is controlled to output the first audio stream and the second audio stream, wherein the second data stream includes the second audio stream.

[0083] In one embodiment, when the extended output device is disconnected, a disconnect signal is generated. When there is a second terminal device in the vehicle to receive the second data stream, the first terminal device and the second terminal device share the same audio playback channel, and the first audio stream and the second audio stream are played simultaneously through the audio output device, that is, the audio output device is controlled to output the first audio stream.

[0084] Second, as Figure 2 As shown, an in-vehicle media playback control method provided by an embodiment of the present invention is applied to a cloud vehicle machine server, wherein the cloud vehicle machine server includes at least one instance resource, each instance resource includes at least one virtual space, and the virtual space is used to push a data stream to a corresponding terminal device; the method includes:

[0085] Step S500: In response to an extended output signal generated by an extended output device, determining a first virtual space corresponding to the extended output signal according to a preset strategy.

[0086] In one embodiment, after the extended output device generates an extended output signal, a first virtual space corresponding to the extended output signal is determined according to a preset strategy, wherein the preset strategy includes determining a terminal device connected to the extended output device according to user settings.

[0087] Step S600: Push the first data stream generated by the first virtual space to the corresponding first terminal device, so that the first terminal device outputs the first data stream to the extended output device through the first communication link.

[0088] Optionally, after determining the first virtual space corresponding to the extended output signal according to a preset strategy in response to the extended output signal generated by the extended output device, the method further includes:

[0089] In response to a disconnection signal generated by the extended output device, it is determined whether a second virtual space that outputs a second data stream exists in a first instance resource where the first virtual space is located.

[0090] If the second virtual space exists, the first audio stream is pushed to the second terminal device, wherein the first data stream includes the first audio stream.

[0091] In one embodiment, the instance resource is connected to the vehicle terminal, and each virtual space in the instance resource is connected to the terminal device. When the extended output device generates a disconnection signal, it is determined whether the first instance resource where the first virtual space is located has a second virtual space that outputs the second data stream, that is, whether there is a second terminal device in the vehicle that receives the second data stream. If there is a second data stream, the first audio stream in the first data stream is pushed to the second terminal device, so that the first audio stream that the second terminal device originally wants to play through the extended output device shares the same channel (the audio output device in the car) for playback.

[0092] Optionally, after determining the first virtual space corresponding to the extended output signal according to a preset strategy in response to the extended output signal generated by the extended output device, the method further includes:

[0093] When at least two virtual spaces output different data streams to different terminal devices respectively, it is determined whether there is a preset configuration rule.

[0094] If the configuration rule exists, the first virtual space is determined according to the configuration rule.

[0095] Specifically, when there are at least two terminal devices playing different multimedia in the car at the same time, that is, at least two terminal devices receive data streams from different virtual spaces respectively, the first terminal device is determined according to the preset configuration rule. For example, when terminal device 1 receives a data stream from virtual space 1 and terminal device 2 receives a data stream from virtual space 2, if the extended output device generates an extended output signal, the corresponding connected terminal device needs to be determined to prevent connection confusion. It is determined whether there is a preset configuration rule to specify the first terminal device.

[0096] In one embodiment, the preset configuration rules include configuration rules set by the user, for example, determining the first terminal device to be connected according to the type of the extended output device, examples including: when the extended output device is a Bluetooth device, connecting terminal device 1; when the extended output device is a wired device, using terminal device 2 as the first terminal device / using the terminal device directly connected to the wired device as the first terminal device.

[0097] An embodiment of the present invention provides a vehicle-mounted media playback control device, which is applied to a vehicle-mounted terminal, wherein the vehicle-mounted terminal includes at least two terminal devices, and the terminal devices are used to receive a data stream from a corresponding virtual space in a cloud vehicle machine server; the method includes:
