Description

Technical Field

[0001] The present invention relates to the field of vehicle networking, and more particularly, to a method and system for reducing the quality of digital content for vehicles. Background Art

[0002] Currently, according to relevant data from the International Energy Agency, the current global average annual total carbon emissions are approximately 33 billion tons, of which the total carbon emissions of the information and communication industry are approximately 1.4 billion tons, accounting for 4.2% of the global total. For example, streaming or delivering digital content (such as video, audio, etc.) over the Internet also typically results in relatively high carbon emissions.

[0003] Currently, "standard mode", "sports mode", "comfort mode", "economy (ECO) mode", etc. are usually set on the vehicle side. In the case of enabling the economy mode, for example, the vehicle can usually adopt certain configurations (usually customizable) to reduce the energy consumption of the vehicle. However, such configurations are usually for the vehicle itself, such as reducing the working intensity of some heating and ventilation devices, weakening the power, reducing the throttle sensitivity, etc., which usually slightly or significantly reduces the driving comfort.

[0004] Modern intelligent connected vehicles usually involve receiving and delivering digital content (such as streamed video, audio, or downloaded video, audio, images, etc.) from, for example, the cloud. And the above-mentioned downloading or streaming usually results in relatively high carbon emissions in the Internet infrastructure (such as data centers, clouds, network elements, etc.). The more data transmitted, the higher the load generated on the IT infrastructure, which will cause higher carbon emissions.

[0005] However, the current economy mode on the vehicle side does not consider intentionally reducing the quality of the digital content delivered to the vehicle, which results in relatively high carbon emissions generated on the IT infrastructure.

[0006] Therefore, in order to further save energy and reduce emissions and make a positive contribution to carbon emission reduction on the IT infrastructure, it is desirable to provide a solution for reducing the quality of digital content for vehicles. Summary of the Invention

[0032] The present invention will be described in detail below with reference to the accompanying drawings. The features of the present invention will be further apparent from the following detailed description. The term "vehicle" used throughout this specification refers to any type of automobile, including but not limited to cars, vans, trucks, buses, etc. For simplicity, the present invention will be described with respect to an "automobile." The term "A or B" used in this specification means "A and B" and "A or B," and does not imply that A and B are exclusive, unless otherwise specified.

[0033] Currently, with the development of the Internet of Vehicles, smart connected vehicles need to receive more data through IT infrastructure and require higher computing power, resulting in higher carbon emissions from IT infrastructure, which is not conducive to the current goal of energy conservation and emission reduction.

[0034] In order to solve the above problems and realize "green and low-carbon network" on the vehicle side, this application proposes a solution for reducing the quality of digital content for vehicles, which is a further extension of the current ECO mode. By setting the digital content quality reduction option, users can intentionally reduce the quality of content delivered to the vehicle side, thereby achieving the purpose of carbon emission reduction without significantly affecting user comfort.

[0035] like Figure 1 As shown, Figure 1 FIG. 1 is a schematic diagram illustrating an architecture of a digital content quality reduction system 100 for a vehicle according to an embodiment of the present invention. The system 100 may include at least an option activation module 102 and a quality reduction module 104 .

[0036] The option activation module 102 may activate a quality reduction option for digital content delivered to the vehicle in response to a user request.

[0037] In one embodiment, the digital content delivered to the vehicle may include, but is not limited to, video, audio, images, traffic data, or map updates, among others.

[0038] In one embodiment, the quality reduction option may be integrated into the economy mode as a configurable option (eg, a sub-option) or a mandatory measure (eg, automatically turned on when the economy mode is enabled).

[0039] In another embodiment, the quality reduction option may be set separately from the economy mode (eg, as a separate mode).

[0040] In one embodiment, the quality reduction option may provide a plurality of sub-options for a plurality of different quality reduction levels.

[0041] Furthermore, each of the plurality of sub-options may be uniformly set for all types of digital content, or may be individually set for different types of digital content.

[0042] As further reference Figure 2 shown Figure 2 FIG. 200 shows a schematic diagram of a user interface integrating a quality reduction option in a vehicle ECO mode according to an embodiment of the present invention.

[0043] As shown in 200, when the user clicks on the ECO icon in the vehicle-side or mobile-side interaction interface, the ECO mode setting is entered. In the ECO mode setting, the "quality reduction option" (denoted as Q_R OPT in Figure 2 ) can be activated by clicking on the corresponding icon in the interface. After activating this option, the quality reduction level for various types of digital content can be further configured. In Figure 2 , three different quality reduction levels, namely low (L), medium (M), and high (H), are uniformly set for all types of digital content. That is, when the low level is enabled, the quality of all types of digital content delivered to the vehicle is set to the low level. For example, for video, the low level means a resolution of 720P (1280*720) and HDR (high dynamic range) is disabled, the medium level means a resolution of 1080P (1920*1080) and HDR is disabled, and the high level means a resolution of 2K (2560*1440) and HDR is enabled.

[0044] Of course, different levels can also be set separately for different types of digital content. For example, the video content can be set to low, while the image and audio content can be set to high.

[0045] Return Figure 1 , the activation or deactivation of the quality reduction option can be set for individual digital content or uniformly for the digital content delivered to the vehicle. In other words, the quality of various digital content delivered to the vehicle can be uniformly reduced by activating the above quality reduction option, or the quality can be reduced for a certain type of digital content when playing / displaying it (for example, when playing video content, reducing the resolution of the video to 720P (by setting it separately on the interaction interface)).

[0046] The quality reduction module 104 can respond to the activation of the quality reduction option and reduce the quality of these digital content delivered to the vehicle in terms of data size, information contained in the data, or data freshness.

[0047] In one embodiment, reducing the quality of digital content in terms of data size, information contained in the data, or data freshness may vary depending on the type of digital content.

[0048] As an example, in the case where the digital content is a video, the resolution or frame rate of the video can be reduced or the color space of the video can be adjusted (e.g., deactivate HDR) in response to the activation of the quality reduction option.

[0049] In another example, in the case where the digital content is audio, the bit rate or number of channels of the audio can be reduced in response to the activation of the quality reduction option.

[0050] In another example, in the case where the digital content is an image, the resolution of the image can be reduced in response to the activation of the quality reduction option.

[0051] In another example, in the case where the digital content is traffic data or map updates, the update frequency or update area of the traffic data or map updates can be reduced in response to the activation of the quality reduction option.

[0052] In one embodiment, the degree of quality reduction can be pre-configured or predefined for different types of digital content, e.g., by selecting different levels as shown in Figure 2 and can also be adjusted by the user as needed at any time (e.g., adjusted to another level, deactivate the quality reduction option for a certain type of digital content (i.e., adjusted back to the normal configuration), etc.), so as to achieve a compromise between comfort and energy conservation and emissions reduction.

[0053] In addition, optionally, the system 100 may further include a display module 106, which can display the estimated carbon emissions savings due to the activation of the quality reduction option before or at the time of activation of the quality reduction option, or can display the carbon emissions savings that have been estimated after the activation of the quality reduction option. This can enable the user to more intuitively obtain information about the estimated / already saved carbon emissions, thereby further improving the user experience.

[0054] Those skilled in the art can understand that the digital content quality reduction system of the present invention can be implemented in the form of hardware or software, and each module can be combined or combined in any suitable manner.

[0055] Figure 3 Fig. shows a schematic flow chart of a digital content quality reduction method 300 for a vehicle according to an embodiment of the present invention.

[0056] Method 300 starts at step 302, and the option activation module 102 can activate the quality reduction option for the digital content delivered to the vehicle in response to a user request.

[0057] In one embodiment, the quality reduction option can be integrated as a configurable option or a mandatory measure in the economy mode, e.g., as shown in Figure 2As shown, after activating the Economy (ECO) mode, the user can choose whether to further activate the quality reduction option, or the quality reduction option is automatically activated after activating the ECO mode.

[0058] In another embodiment, the quality reduction option can also be set separately from the economy mode.

[0059] In one embodiment, the quality reduction option provides a plurality of sub-options regarding a plurality of different quality reduction levels. For example, the quality reduction levels can be divided into three levels: low, medium, and high. Of course, it can be understood that any other suitable levels for different digital content types can also be set.

[0060] Furthermore, each of the plurality of sub-options can be set uniformly for all types of digital content, or set separately for different types of digital content. For example, the quality of traffic data or map updates can be set to high, while the quality of video, audio, and images can be set to low, thereby, for example, obtaining a better driving experience during navigation while also saving carbon emissions.

[0061] In one embodiment, the activation of the quality reduction option can be implemented on the vehicle side or on a mobile device (e.g., a smart phone) communicatively connected to the vehicle.

[0062] In step 304, the quality reduction module 104 can reduce the quality of digital content in terms of data size, information contained in the data, or data freshness in response to the activation of the quality reduction option.

[0063] For different digital content, different ways can be adopted to reduce the quality of digital content. In one example, in the case where the digital content is a video, the resolution or frame rate of the video can be reduced or the color space of the video can be adjusted (e.g., reducing the quality by deactivating HDR); in the case where the digital content is audio, the bit rate or number of channels of the audio can be reduced; in the case where the digital content is an image, the resolution of the image can be reduced; or, in the case where the digital content is traffic data or map updates, the update frequency or update area of the traffic data or map updates can be reduced (e.g., only updating the navigation-related area).

[0064] In one embodiment, the estimated carbon emissions savings after activating the quality reduction option can be displayed before or at the time of activation (e.g., on the in-vehicle center console screen or mobile device).

[0065] In another embodiment, the carbon emissions savings that have been achieved can also be estimated during or after driving (by activating the quality reduction option and reducing the quality of digital content accordingly) and displayed to the user.

[0066] In one embodiment, the user can switch the quality of digital content at any time according to needs (switch the quality from low to high) or deactivate the quality reduction option. For example, if the user wishes to obtain higher quality for map updates (higher update frequency, etc.) when starting navigation, the user can deactivate the quality reduction option for map updates.

[0067] In one embodiment, the activation or deactivation of the quality reduction option is set for individual digital content or uniformly for the digital content of the vehicle. In one example, buttons or other interactive elements can be provided for a specific video for the user to turn off / deactivate the quality reduction mode for that specific video, while the settings for other digital content remain unchanged.

[0068] Thus, by further integrating the "quality reduction mode" for in-vehicle digital content on the vehicle side, videos and images can be delivered at a reduced resolution, audio can be delivered at a reduced bit rate, traffic data and map updates can be delivered at a lower frequency, etc. Thus, "network green and low-carbon" on the vehicle side can be achieved, thereby further contributing to carbon emission reduction.

[0069] Figure 4 An exemplary vehicle 400 supporting digital content quality reduction according to an embodiment of the present invention is shown. The vehicle 400 may include various software and hardware components connected via a bus 416.

[0070] The vehicle 400 may include the digital content quality reduction system 100 as described above, which may be configured to activate the quality reduction option for the digital content delivered to the vehicle in response to a user request, and reduce the quality of the digital content in terms of data size, information contained in the data, or data freshness in response to the activation of the quality reduction option.

[0071] The digital content quality reduction system 100 may be integrated in the in-vehicle infotainment system 402, which is an in-vehicle integrated information processing system formed by using a dedicated in-vehicle central processor based on the vehicle body bus system and Internet services, including an in-vehicle information system and an in-vehicle entertainment system. Its functions are mainly divided into navigation and positioning, vehicle services, multimedia, communication and social networking, life services, etc., and it is an important part of cockpit electronics. For example, when the system 100 activates the quality reduction option for the digital content delivered to the vehicle in response to a user request, the quality of the digital content for various services in the in-vehicle infotainment system 402 can be downgraded.

[0072] The vehicle 400 may further include a communication unit 404, which can be used to connect to the network to obtain the delivered digital content (e.g., videos, audio, images, traffic data, or map updates).

[0073] Further, vehicle 400 may also include a control unit 406, which may be used to control the vehicle to obtain or display digital content with reduced quality (e.g., after activating the quality reduction mode) or normal quality (e.g., obtained through networking).

[0074] Further, vehicle 400 may also include a content playback unit 408, which may be configured to display or play digital content with reduced quality or normal quality (e.g., display an image or play audio, video, etc. on the center control screen with reduced quality after activating the quality reduction mode).

[0075] In addition, vehicle 400 may also include a sensor system 410, a wireless transceiver 412, a Global Navigation Satellite System (GNSS) receiver 414, and so on.

[0076] The sensor system 410 may include any suitable number of accelerometers, gyroscopes, and / or magnetometers. In some embodiments, the sensor system 410 may be part of the inertial measurement unit of vehicle 400. The sensor system 410 may be used to provide and / or verify motion and orientation information, monitor wheel and driveline performance, and / or measure the oscillation amplitude and frequency of vehicle 400 and / or components of vehicle 400. As an example, an accelerometer may measure the vibration of vehicle 400, such as movement or mechanical oscillation about the balanced positioning of components of vehicle 400. In one embodiment, the gyroscope and magnetometer of the sensor system 410 may be used to measure the rotational state of the vehicle and its orientation relative to magnetic north, and to measure and calibrate the estimation of the turning radius and / or model at the current speed and / or the maneuverability measurement at the current speed (especially when used in conjunction with measurements from other external and internal sensors, such as other sensors, such as speed sensors, wheel tick sensors, and / or odometer measurements). Additionally, the sensor system 410 may also include radar, LIDAR, vision sensors, and so on. For example, LIDAR may provide a means to more deterministically detect the distance (and orientation) of an object (especially with respect to an object of unknown size and shape).

[0077] The wireless transceiver 412 may be configured to transmit and receive data messages and elements via a short-range wireless communication protocol (e.g., etc.) and / or via a local area network and / or a wide area network, and / or via a cellular network, and / or via any suitable wireless network. Of course, it should be understood that these are merely examples of networks that can be utilized by vehicle 400 over a wireless link, and the claimed subject matter is not limited in this regard. In one embodiment, the wireless transceiver 412 may include various combinations of WAN, WLAN, and / or PAN transceivers. In one embodiment, the wireless transceiver 412 may also include a Bluetooth transceiver, a ZigBee transceiver, or other PAN transceivers.

[0078] The GNSS receiver 414 can be configured to receive and digitally process signals from navigation satellites (and / or other vehicles) to provide the receiver's position, velocity, and time. The GNSS receiver 414 can include hardware and / or software components. In one embodiment, the GNSS signals from the GNSS satellites received by the GNSS receiver 414 are used by the vehicle 400 for position determination and / or for the determination of GNSS signal parameters and demodulated data.

[0080] As Figure 5 shown, the system 500 can include a memory 502 and at least one processor 504. The memory 502 can include RAM, ROM, or a combination thereof. The memory 502 can store computer-executable instructions that, when executed by the at least one processor 504, cause the at least one processor 504 to perform the various functions described herein, including: activating a quality reduction option for digital content delivered to a vehicle in response to a user request; and reducing the quality of the digital content in terms of data size, information contained in the data, or data freshness in response to activation of the quality reduction option.

[0081] In some cases, the memory 502 can in particular include a BIOS that can control basic hardware or software operations, such as interactions with peripheral components or devices. The processor 504 can include intelligent hardware devices (e.g., a general-purpose processor, DSP, CPU, microcontroller, ASIC, FPGA, programmable logic device, discrete gate or transistor logic components, discrete hardware components, or any combination thereof).

[0082] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof.
