[0019] Figure 1 This is a schematic diagram of the structure of a multimedia management system in one embodiment of the present application. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Embodiment 1:

[0022] As attached Figure 1 As shown, in order to solve the above technical problems, the present application provides a multimedia management system, including a multimedia control unit, the multimedia control unit at least including a first data output module and a second data output module; and also including:

[0023] Multiple display modules, any of which includes at least a display chip and a Bluetooth control chip; and a data transmission unit, the input end of the data transmission unit is connected to the output end of the first data output module and the output end of the second data output module; the output end of the data transmission unit is respectively connected to the display chip and the Bluetooth control chip.

[0024] It should be noted that, in this embodiment, the first data output module and the second data output module may be responsible for processing and outputting the video, audio and other contents in the multimedia data respectively. They send the data to the display module and the Bluetooth control chip through the data transmission unit. In addition, the number of the first data output module and the second data output module is not limited, and a plurality of video output modules and audio output modules may be included in the multimedia control unit, which is not limited thereto.

[0025] Preferably, the first data output module may be used for video output, and the second data output module may be used for audio output.

[0026] The display chip is used to control the display content of the display; the Bluetooth control chip is used to process Bluetooth communication, realize the connection and data transmission with external Bluetooth devices; the audio exciter is used to process sound signals, convert sound signals into level signals and control the sound of the display panel. Through these chips, the display module can display multimedia content and has Bluetooth function to realize interaction with external devices.

[0027] The data transmission unit is responsible for handling the transmission and distribution of data. It receives data from the multimedia control unit and sends it to the display module and the Bluetooth control chip and the audio exciter respectively to realize the display of multimedia content and Bluetooth communication. Through the design of the data transmission unit, the system can achieve efficient data transmission and management.

[0028] In this embodiment, through the design of multiple display modules and data transmission units, passengers can enjoy different multimedia content at the same time, which improves the personalization and comfort of the riding experience. Each display module is equipped with a Bluetooth control chip and an audio exciter, which can realize connection and data transmission with external Bluetooth devices, increasing the interconnectivity and functional scalability of the system.

[0029] By centrally processing data transmission, the system can reduce complex wiring and management costs, and improve the maintainability and reliability of the system. The overall system design allows passengers to freely choose and enjoy a variety of multimedia content, while achieving seamless connection with external devices, improving the overall user experience and riding comfort.

[0030] Preferably, the first data output module is defined as being responsible for processing the video data output. For example, when a passenger chooses to watch a video on the front row display, the first data output module will send the video signal to the front row display module.

[0031] The second data output module is defined as being responsible for processing audio data output. For example, when passengers simultaneously choose to listen to music in the back seats, the second data output module will send the audio signal to the Bluetooth control chip or audio exciter or vehicle audio system in the back seats.

[0032] Assume that there are two display modules inside the vehicle, one installed at the front headrest position and the other installed at the rear center armrest box. The display chip of the front display module will receive the video signal from the first data output module and control the front display to display the corresponding video content, such as the movie or video program selected by the passenger. The rear display module will also receive the video signal from the first data output module and independently display another video content, such as the rear passenger can select a different movie or video program.

[0033] Each display module is equipped with a Bluetooth control chip to handle Bluetooth communications. For example, if a rear passenger wants to play music on their phone via Bluetooth, the Bluetooth control chip will be responsible for pairing with the phone and receiving audio data for playback.

[0034] Each display module is equipped with an audio actuator to process sound signals and realize self-sound. For example, if the rear passengers want to listen to their favorite content, they can output the favorite content to the display they control, and the audio actuator where the display is located can drive the screen panel to sound by itself, thereby realizing independent playback of audio data.

[0035] The data transmission unit receives the video and audio data from the multimedia control unit, and then sends the video data to the corresponding display module, and sends the audio data to the Bluetooth control chip or the audio exciter or the vehicle audio system.

[0036] Through the design of the data transmission unit, the system can ensure the synchronous transmission of video and audio data while providing a diverse multimedia experience.

[0037] In summary, through the design of multiple display modules and data transmission units, passengers can enjoy different multimedia content at different locations in the car at the same time, such as watching videos in the front row and listening to music in the back row, thus improving the personalization and comfort of the riding experience. At the same time, each display module has Bluetooth function, which realizes seamless connection with external devices and increases the interconnectivity and functional scalability of the system.

[0038] In this embodiment, the system further includes an audio processing unit; an input end of the audio processing unit is connected to an output end of the first data output module, or an output end of the second data output module.

[0039] It should be noted that when the second data output module is used as an audio output module, the second data output module is connected to an audio processing unit. The audio processing unit may include an audio control chip. The audio control chip is connected to multiple speakers for externally outputting audio.

[0040] Preferably, the audio processing unit is responsible for processing the output and control of audio data. Its input end is connected to the output end of the second data output module to receive audio data from the multimedia control unit. In the audio processing unit, an audio control chip may be included to process functions such as decoding, amplification and adjustment of audio signals. The audio control chip may be connected to a plurality of speakers to achieve external output of audio. These speakers may be distributed in different positions in the vehicle, such as the front row, the back row or the roof.

[0041] When a passenger chooses to play audio in the car, the multimedia control unit sends the audio data to the second data output module.

[0042] The second data output module transmits the audio data to the audio processing unit.

[0043] In the audio processing unit, the audio control chip processes and decodes the audio signal, and then sends the processed audio signal to the connected speakers.

[0044] The speakers convert the audio signals into sound and output them to the interior of the vehicle through external speakers, allowing passengers to hear music, radio or other audio content.

[0045] By introducing an audio processing unit and connecting multiple speakers, the system achieves a richer and more three-dimensional audio output experience. Passengers can enjoy high-quality audio content at different locations in the car at the same time. For example, the front and rear passengers can select different music or radio programs respectively, thus improving the overall riding comfort and entertainment experience.

[0046] In the present application, the data transmission unit at least includes a plurality of serializer chips; any of the display modules also includes a deserializer chip and an audio exciter.

[0047] It should be noted that by adding an audio exciter to the display module, the screen can be made to sound. After the cockpit module outputs the audio to the display screen, the audio exciter can directly make the sound in the display screen without the need for additional speakers or other equipment.

[0048] Furthermore, any one of the serializer chips and the deserializer chip is correspondingly connected via a serial communication protocol; the multimedia information output from the first data output module or the second data output module passes through the serializer chip and the deserializer chip in turn before being transmitted to the display chip and the Bluetooth control chip, or is transmitted to the display chip and the audio exciter, respectively.

[0049] Preferably, the data transmission unit includes a plurality of serializer chips, which are responsible for converting the multimedia information into a serial data stream for transmission. Each display module also includes a deserializer chip, which is used to parse the received serial data stream into the original multimedia information.

[0050] Any serializer chip and the corresponding deserializer chip are connected to each other through a serial communication protocol. This means that the serial data stream sent by each serializer chip will communicate with the corresponding deserializer chip through a specific communication protocol and be parsed according to the same protocol. Preferably, the serial communication protocol can adopt LVDS, MIPI, HDMI, etc., but are not limited to this. These protocols define the electrical characteristics, signal format, timing requirements, etc. of data transmission, thereby ensuring high-speed transmission and reliability of serial data.

[0051] When the multimedia control unit needs to send multimedia information to the display module or the Bluetooth control chip or the audio exciter, the multimedia information first passes through the data transmission unit.

[0052] In the data transmission unit, multiple serializer chips convert the multimedia information into serial data streams and send them to corresponding deserializer chips according to the serial communication protocol.

[0053] The deserializer chip receives and parses the serial data stream, converting it into original multimedia information.

[0054] The parsed multimedia information is transmitted to the display chip or the Bluetooth control chip or the audio exciter so that the display module can display the content or perform Bluetooth communication or directly play the audio.

[0055] For example, suppose there are two display modules inside the vehicle, one located at the front headrest and the other located at the rear center armrest. When the front passenger chooses to watch a video, the multimedia control unit sends the video information to the data transmission unit. Among them, the first serializer chip converts the video information into a serial data stream and sends it to the deserializer chip in the front display module through a serial communication protocol. The deserializer chip parses the data stream and passes the video information to the display chip, which is finally displayed on the front display. The same process also applies to the rear display module as well as the Bluetooth control chip and audio exciter to achieve audio output or communication with external Bluetooth devices.

[0056] This embodiment realizes efficient data transmission and management, ensures smooth transmission and display of multimedia information between different modules, and thus provides a smoother and richer user experience.

[0057] In the present application, the first data output module and the second data output module respectively include a plurality of output ports to output a plurality of multimedia information on the plurality of display modules at the same time.

[0058] In the present application, the system further includes an environment sensing unit; one end of the environment sensing unit is connected to the multimedia control unit, and the other end of the environment sensing unit is connected to any of the display modules.

[0059] It should be noted that the environmental perception unit is responsible for sensing the environmental information inside the vehicle, such as light intensity, temperature, humidity, etc.

[0060] One end of it is connected to the multimedia control unit to receive and transmit environmental information.

[0061] The other end is connected to any display module to receive environmental information and display or process it accordingly.

[0062] When the ambient perception unit detects a change in light intensity inside the vehicle, it passes this information to the multimedia control unit.

[0063] After receiving the light intensity information, the multimedia control unit can adjust the brightness or contrast of the display module according to the information to adapt to environmental changes.

[0064] For example, when the light in the car dims, the environmental perception unit detects this change and transmits the information to the multimedia control unit. After receiving the information, the multimedia control unit automatically adjusts the brightness of the display module so that it is still clearly visible in a dark environment.

[0065] By introducing an environmental perception unit, the system can automatically adjust the brightness and contrast of the display according to environmental changes inside the vehicle to provide a more comfortable and adaptive display effect. This intelligent adjustment function can automatically adjust according to passenger needs and environmental changes without the need for manual intervention by passengers, thereby improving passenger comfort and satisfaction.

[0066] In the present application, the system further includes a power supply unit; the power supply unit is connected to the multimedia control unit and is used to provide working power.

[0067] It should be noted that the power supply unit is a key component of the system, which is responsible for providing a stable power supply for the entire multimedia management system. It can be connected to the vehicle's main power system, such as a battery or a generator, to obtain electrical energy.

[0068] The power supply unit may include power management circuitry to monitor and manage the distribution of power to ensure that the various parts of the system operate at appropriate voltages and currents.

[0069] When the vehicle is started, the power supply unit is activated and starts working, providing power to the multimedia control unit and other related modules.

[0070] After receiving the power supply, the multimedia control unit starts the initialization and startup process, and prepares to process and output multimedia data.

[0071] At the same time, the power supply unit also provides necessary power to other modules such as display module, audio processing unit, environmental sensing unit, etc. to ensure that they can work normally.

[0072] For example, when a passenger enters the vehicle and starts the system, the power unit activates and starts to provide working power to the multimedia control unit. After receiving the power, the multimedia control unit starts and establishes communication connections with the display module, audio processing unit, etc. At the same time, the power unit also provides power to the display module so that it can display multimedia content. In addition, the power unit also provides power to the environmental sensing unit, enabling it to sense environmental changes inside the vehicle and adjust the brightness and contrast of the display according to these changes. By introducing the power unit, the system can ensure that each module can obtain a stable power supply during the operation of the vehicle, thereby ensuring the normal operation of the multimedia management system and the comfort experience of the passengers.

[0073] In summary, Example 1 has made a detailed analysis and example explanation of the construction of a multimedia management system proposed in this application. This application realizes the output and management of video and audio through multiple functional modules, and has functions such as Bluetooth connection, environmental perception and power supply. Passengers can enjoy different multimedia content at different positions in the car at the same time, such as watching TV series audio and video in the front row and watching movies in the back row, which improves the personalization and comfort of the riding experience. Each display module is equipped with a Bluetooth control chip, which realizes connection and data transmission with external Bluetooth devices, and increases the interconnectivity and functional extensibility of the system. The introduction of an environmental perception unit can automatically adjust the brightness and contrast of the display according to environmental changes inside the vehicle, providing a more comfortable and adaptable display effect. This application realizes a comprehensive multimedia solution, provides new possibilities for entertainment and information interaction inside the vehicle, and improves the riding experience and comfort.

[0074] Embodiment 2:

[0075] In order to solve the above technical problems, the present application also proposes a multimedia management device, the device comprising:

[0076] A multimedia control center, the multimedia control center includes a video output module and an audio output module; and a plurality of display screens, any of which includes at least a display chip, a Bluetooth control chip and an audio exciter.

[0077] The output end of the video output module is respectively connected to any of the display chips, any of the Bluetooth control chip and the audio exciter; the output end of the audio output module is respectively connected to any of the display chips, any of the Bluetooth control chip and the audio exciter.

[0078] Preferably, assuming an example of a vehicle-mounted multimedia management device, its components include:

[0079] Multimedia control center: Video output module: responsible for processing and outputting video signals; Audio output module: responsible for processing and outputting audio signals.

[0080] Multiple display screens: Each display screen includes a display chip, a Bluetooth control chip, and an audio exciter.

[0081] When the passenger starts the in-vehicle multimedia management device, the multimedia control center starts working and initializes each module.

[0082] Furthermore, the device also includes an audio device; the input end of the audio device is connected to the output end of the audio output module.

[0083] Assume that three users choose to watch different audio and video in the car. The video output module receives the video signal and processes it, and then outputs the processed video signal. The output end of the video output module is respectively connected to the display chip of the selected display screen, the Bluetooth control chip and the audio exciter. The display chip receives the video signal and displays it on the selected display screen. At the same time, the Bluetooth control chip can also transmit the video signal to an external Bluetooth device to achieve extended display or projection of the video. The audio output module receives the audio signal and processes it, and then outputs the processed audio signal. The output end of the audio output module is respectively connected to the display chip of the selected display screen, the Bluetooth control chip and the audio exciter. The display chip receives the audio signal and plays it out through the speaker, so that passengers can hear the audio content. At the same time, the Bluetooth control chip can also transmit the audio signal to external Bluetooth speakers or headphones and other devices to achieve extended audio output or headphone monitoring.

[0084] Through the design of the above equipment, passengers can enjoy different multimedia content at different locations in the car. At the same time, the presence of the Bluetooth control chip enables the device to have the function of interconnection with external Bluetooth devices, increasing the scalability and functionality of the system.

[0085] Embodiment three:

[0086] In order to solve the above technical problems, the present application also proposes a vehicle, which at least includes any multimedia management system as described above.

[0087] Preferably, assume that a smart luxury car is taken as an example, and its components are:

[0088] Multimedia Management System:

[0092] Audio processing unit: includes audio control chip and multiple speakers.

[0093] Environmental perception unit: used to perceive the environmental information inside the vehicle.

[0094] Power supply unit: provides working power for the entire system.

[0095] When passengers enter the smart luxury car and start the vehicle, the multimedia management system starts working and initializes each module.

[0096] Since each display has its own Bluetooth control chip and audio exciter, different audio and video content can be played on different displays. For example, the driver can view navigation information on the front display while the co-pilot can watch a movie on the display next to it without interfering with each other.

[0097] The use of Bluetooth technology allows passengers to connect to a specific display using wireless headphones or other Bluetooth devices so that they can receive and enjoy multimedia content of their own choice without being affected by other occupants of the car.

[0098] Preferably, each passenger can select different multimedia content according to their needs to provide a personalized riding experience.

[0099] Furthermore, since Bluetooth is a widely used wireless technology, this solution is compatible with most modern mobile devices, providing greater flexibility and convenience.

[0100] In summary, the above-mentioned vehicle achieves simultaneous playback of multiple different multimedia sources by integrating Bluetooth control chips and audio exciters inside each display screen. Provides an independent multimedia experience for each passenger. Improves the flexibility and compatibility of the multimedia system in the cockpit and reduces system complexity and cost. The environmental perception unit sends state change information to the multimedia control unit. The multimedia control unit adjusts the brightness of the display screen according to the light information to adapt to the dark environment. The power supply unit obtains power from the vehicle's main power system and provides a stable power supply for the multimedia management system.

[0101] Through this vehicle design, passengers can enjoy rich and diverse multimedia content in the car, such as watching videos, playing audio, etc. At the same time, the system's environmental perception unit can automatically adjust the brightness of the display to adapt to different lighting conditions, providing a more comfortable and personalized experience. In addition, the entire system is powered by the power supply unit to ensure the normal operation of the multimedia management system.

[0102] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0103] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal (which can be a mobile phone, a computer, a server, an air conditioner, or a network device, etc.) to execute the methods described in each embodiment of the present invention.
