Description

[0001] This application is a divisional application of the invention patent application with the application date of November 22, 2019, application number 201980094766.1, and invention name “Method and system for displaying content using matrix code”. Background Art

[0002] A technician servicing a vehicle may reference the maintenance information in order to properly and more efficiently maintain the vehicle than a technician who does not reference the maintenance information. The maintenance information may be provided in various forms, such as maintenance information printed on paper or maintenance information electronically displayed on a display. Various problems may arise when a technician attempts to electronically display the maintenance information on a display, particularly when the maintenance information is stored in a video format outside of a computing device that the technician uses to search for the maintenance information or access the maintenance information through a link within a web page. As an example, a technician may use a computing device that is not configured to display videos and / or is not configured to traverse links within a web page to search for off-board maintenance information. As another example, a technician may use a computing device to search for off-board maintenance information under poor network conditions. Poor network conditions may cause an unexpectedly long time to download an off-board maintenance information video, multiple attempts to download an off-board maintenance information video, or streaming of an off-board maintenance information video at a speed that is too slow for continuous display of the off-board maintenance information video.

[0027] I. Introduction

[0028] This specification describes several exemplary embodiments, at least some of which involve displaying a computer-readable file on a display. In some embodiments, the computer-readable file includes content related to maintaining a vehicle (such as a car) and / or a link to the content. In at least some embodiments, when the computer-readable file is played on the display, additional information (e.g., textual maintenance information and / or textual diagnostic information) may be displayed on the display. In some of these embodiments, the display of the user's computing device may not be configured to display the computer-readable file, or may not be configured to display both the computer-readable file and the additional maintenance information while displaying the computer-readable file. In addition, in these and / or other embodiments, the computing device that displays the link to other content may not be configured to traverse the link.

[0029] This specification describes embodiments that include displaying one or more computer-readable files on at least one of the first and second computing devices using a first computing device and a second computing device. At least some of these embodiments can include displaying additional maintenance information on at least one of the first and second computing devices. Examples of additional maintenance information include diagnostic flowcharts, removal and replacement instructions, still images of vehicle components, repair orders, and links to additional maintenance information. Other examples of additional maintenance information are possible.

[0030] In at least some embodiments, at least one of the first and second computing devices can determine a situation indicating that the first computing device cannot display the one or more files at at least a minimum quality level. For example, the first computing device may include a display that is not configured to display video files or specific types of video files (e.g., high-definition video files or video files with specific file extensions). As another example, the first computing device may be connected to a communication network that is insufficient to transmit the one or more files to be viewed at the first computing device at a minimum quality level, while the second computing device is connected to a communication network that is sufficient to transmit the one or more files to be viewed at the second computing device at a minimum quality level. As another example, the first computing device may be configured to render a web page, but cannot traverse links embedded in the web page.

[0031] In at least some embodiments, the communication network used by the first and second computing devices may be the same communication network, such as a cellular data network. In at least some of those embodiments, the communication network may include a cellular data network configured with different levels of network technology, such as network technology commonly referred to as 1G, 3G, or 4G (LTE). The first and second computing devices may operate under different maintenance plans provided by the provider of the communication network. For example, the first computing device may operate under such a maintenance plan in which the rate at which the communication network transmits data to the first computing device is throttled (e.g., reduced) in certain circumstances, such as when the first computing device has received an amount of data exceeding a threshold during a particular maintenance period or during certain periods of the day (e.g., between the period of 7:00 a.m. and 7:00 p.m.). As another example, the second computing device may operate under such a maintenance plan in which the communication network does not throttle the rate at which data is transmitted to the second computing device. Following the above example, even if both the first and second computing devices are configured to be able to display the one or more files, if the transmission rate of each data packet carrying each portion of the one or more files is throttled, the first computing device may be unable to display the one or more files at a minimum quality level.

[0032] In at least some embodiments, the communication networks used by the first and second computing devices may be different communication networks. For example, the first computing device may be connected to network, and the second computing device may be connected to a cellular network having 4G (LTE) network technology. According to this embodiment, even if both the first and second computing devices are configured to be able to display the one or more files, one or the other of the two communication networks may be more suitable for providing the one or more files to the computing device connected to the network. In addition, the signal strength received at one of the first and second computing devices may be relatively greater than the signal received at the other of the first and second computing devices.

[0033] In at least some embodiments, the first computing device operates as a client computing device relative to the remote server and operates as a server for the second computing device. The remote server can determine one or more files in response to a request sent by the first computing device to the remote server. In some embodiments, the remote server provides the one or more files to the first computing device. In these or other embodiments, the remote server provides a link to the one or more files to the first computing device. The first computing device can provide the one or more files and / or a link to the one or more files to a second computing device operating as a client of the first computing device. The first computing device and / or the second computing device can be configured as a diagnostic computing device.

[0034] In at least some embodiments, the first computing device and the second computing device comprise improvements to existing computing devices such that those embodiments provide improvements to a group of machines, particularly when further described embodiments involve at least one server (such as a file server and / or a media server).

[0035] Many embodiments described in this specification include displaying the one or more files on a display. Any embodiment that includes displaying the one or more files may, but need not, include displaying an advertisement on the display before displaying the one or more files, and / or the one or more files may include an advertisement, such as an advertisement at the start point of the one or more files. The advertisement may include a video advertisement.

[0036] II. Exemplary Systems

[0037] Figure 1A A block diagram of a system 100 is shown in accordance with an exemplary embodiment. The system 100 includes a communication network 102, a diagnostic computing device (DCD) 104, a server 106, a companion computing device (CCD) 108, and a personal area network (PAN) 110.

[0038] The communication network 102 may include one communication network or multiple communication networks. Two or more of the multiple communication networks may be operably coupled to each other. The communication network of the communication network 102 may communicate via a wired communication network and / or a wireless communication network. In some embodiments, the communication network of the communication network 102 includes a circuit-switched digital network and / or a packet-switched network. The communication network 102 includes multiple network devices. As an example, the network devices on the communication network 102 may include access points, antennas, base stations, gateways, hubs, modems, network cables, network interface cards, relays, receivers, routers, switches, transceivers and / or transmitters. Any one or more of these network devices may be installed in the communication network 102 as an intermediary network device. Other examples of the network devices on the communication network 102 are also possible.

[0039] In some embodiments, the communication network 102 includes a local area network (LAN) and / or a wide area network (WAN). The local area network and / or the wide area network may use packet switching or circuit switching technology to carry data. The local area network and / or the wide area network may include an air interface or wires to carry data. The communication network 102 may include a network (such as a communication network commonly referred to as the Internet) or at least a portion of a network that communicates using the Transmission Control Protocol (TCP) and the Internet Protocol (IP).

[0040] The term "data" within this specification may be used interchangeably with the term "information" and / or similar terms. Unless otherwise specified, the data described in this specification may include a single data or multiple data. The data described herein may be transmitted (e.g., uploaded) and / or received (e.g., downloaded). As an example, any transmission of the data described herein may occur directly from a transmitting device (e.g., a transmitter) to a receiving device (e.g., a receiver). As another example, any transmission of the data described herein may occur indirectly from a transmitter to a receiver via one or more intermediate network devices. The transmission of any data described herein may include transmitting data through an air interface (e.g., using a radio signal, i.e., wirelessly). Any transmission of the data described herein may include transmitting data through a network cable (e.g., a single wire, a twisted pair, an optical cable, a coaxial cable, a wiring harness, a power cord, a printed circuit, a CAT5 cable, and / or a CAT6 cable). Wires may be referred to as "conductors" and / or other terms. As an example, the transmission of data on a conductor may occur electrically and / or optically. The transmission of data may be referred to as "communication". Communication may, but does not necessarily, include "request communication" or "response communication".

[0041] The data may represent various things, such as objects and situations. Objects and situations may, but need not necessarily, be mapped to data structures (e.g., tables). The processor may reference the data structures to determine the objects and / or situations represented by the data. As an example, the data received by the processor may include a vehicle identifier and / or a symptom identifier. The processor may determine other data, such as a content description of one or more files, by determining a content description and / or one or more files associated with the vehicle identifier and / or the symptom identifier. The data may represent a state of a computing device determined at the processor. For example, the data may indicate a state indicating a reception level of the DCD 104 from the communication network 102 or a connection state (e.g., connected or not connected) to the PAN 110.

[0042] The DCD 104 is a computing device configured to perform diagnostic functions related to another object, such as a vehicle and / or an electronic control unit (ECU) within the vehicle. The ECU within the vehicle includes an onboard computing device configured to perform vehicle functions. The ECU can perform vehicle functions when the ECU is operably connected to the DCD and when the ECU is not operably connected to the DCD. Although the ECU can be configured to perform self-diagnosis, for the purposes of this specification, the ECU is not a DCD. The ECU is installed in the vehicle. As an example, the ECU may include an ECU installed by the manufacturer of the vehicle, an ECU installed by a technician to replace an ECU installed by the manufacturer of the vehicle, an ECU installed by a technician to replace an ECU installed by a technician, or an aftermarket ECU installed by a technician to equip the vehicle to perform one or more additional vehicle functions. A DCD, such as the DCD 104, can be removably attached to the vehicle so that the DCD can perform its diagnostic functions. As an example, a DCD, such as the DCD 104, can be removably attached to the vehicle by removably attaching the DCD to an onboard diagnostic connector, such as a data link connector, within the vehicle. DCD 104 may include an embedded processor configured to perform diagnostic functions.

[0043] The DCD 104 may also be configured to perform non-diagnostic functions related to other objects. Non-diagnostic functions may, but need not necessarily, include programming functions, calibration functions, and / or adjustment functions. The DCD 104 may be configured to communicate with a plurality of computing devices. The plurality of computing devices may include onboard computing devices installed in other objects, such as ECUs in vehicles. The plurality of computing devices may also include off-board computing devices of the DCD 104 and other objects. Those off-board computing devices may include servers 106 and CCD 108 as well as other off-board computing devices.

[0044] The DCD 104 or any described embodiment of the DCD may, but need not necessarily, comprise or be implemented as part of a small-sized portable (ie, mobile) electronic device, such as a smartphone (eg, a smartphone from Apple Inc. of Cupertino, California). Smartphone, Samsung Electronics Co., Ltd. in Maetan-Dong, Yeongtong-gu, Suwon-si, Gyeonggi-do, South Korea smartphones), tablet devices (e.g., Apple's tablet device, SAMSUNG GALAXY TAB tablet device from Samsung Electronics Co., Ltd.), a wearable computing device (e.g., a wireless network watch device or a personal headset device), or a personal computing system (e.g., a laptop computer or a non-laptop computer configuration).

[0045] CCD 108 is a computing device configured to communicate with multiple computing devices. For example, CCD 108 can be configured as a client computing device that communicates with server 106. As another example, CCD 108 can be configured to communicate with DCD 104. CCD 108 and DCD 104 can communicate with each other via PAN 110 and / or communication network 102. CCD 108 or any described embodiment of the CCD can, but need not necessarily, include or be implemented as part of a small-sized portable electronic device, such as a smartphone, a tablet device, a wearable computing device, or a personal computing system.

[0046] The server 106 is a computing device configured to serve multiple client computing devices (such as the DCD 104 and the CCD 108). The server 106 can communicate with the DCD 104 and the CCD 108 via the communication network 102. As an example, the server 106 can receive a request communication (e.g., a communication with a request) sent from the CCD 108 via the communication network 102. For example, the request communication can include a request for diagnostic information, a vehicle identifier, a component identifier, and / or a symptom identifier. The server 106 can transmit a response communication (e.g., a response to the request communication) to the CCD 108 via the communication network 102. The response communication can include data obtained by the server 106 from a computer-readable memory and / or a database. The data in the response can, but does not necessarily, include a content description and / or a matrix code.

[0047] PAN 110 is a communication network that can be established between two or more computing devices. For example, PAN 110 can be established between DCD 104 and CCD 108. In some embodiments, PAN 110 can include a wired PAN, such as a universal serial bus (USB) including a four-wire cable. In these or other embodiments, PAN 110 can include a wireless PAN, such as a wireless PAN configured to operate according to one of the following standards: Institute of Electrical and Electronics Engineers for Wireless Personal Area Networks (PANs) 802.15 standards (e.g., 802.15.1, 802.15.3, 802.15.4 or 802.15.5), developed by the Bluetooth Special Interest Group (SIG) in Kirkland, Washington Version 4.1 or 4.2 of the standard or the Wireless USB 1.0 standard maintained by the WiMedia Alliance, Inc. of San Ramon, California.

[0048] Next, Figure 1B A variation of system 100 according to an exemplary embodiment is shown. In this variation of system 100, server 106 is represented as a plurality of servers. In other words, in Figure 1B in Figure 1A The servers 106 shown in FIG. 1 are represented as file servers 114 and media servers 116. The terms "file server" and "media server" are used to distinguish between the two servers in FIG. Figure 1B 102. The two servers shown in the figure are not intended to limit the functions performed by any of the two servers. In some embodiments, the file server 114 and the media server are co-located on the communication network 102. As an example, the co-located servers can use the same network address. In other embodiments, the file server 114 and the media server are distributed on the communication network. In this case, the file server 114 and the media server 116 can have different network addresses.

[0049] Figure 1B Also shown is that system 100 may include memory 118 and memory 120. Although Figure 1BAn embodiment in which the file server 114 is separate from the memory 118 is shown, but in alternative embodiments, the file server 114 may include and / or be co-located with the memory 118. The memory 118 may contain a database accessible by the file server 114. In particular, the memory 118 may include links associated with files stored in the memory 120. Even more particularly, the links stored in the memory 130 may include video links associated with video files. As another example, the memory 118 may include data files and / or applications. The applications may, but need not necessarily, include an application configured to determine data stored in the memory 118 (such as data associated with a vehicle identifier of the vehicle 112, component identifiers of components located in and / or on the vehicle 112, and / or symptom identifiers of symptoms exhibited by the vehicle 112).

[0050] Likewise, despite Figure 1B An embodiment is shown in which the media server 116 is separate from the memory 120, but in alternative embodiments, the media server 116 may include and / or be co-located with the memory 120. The memory 120 may contain a database that is valuable by the media server 116. In particular, the memory 120 may include one or more files associated with the links stored in the memory 118.

[0051] also, Figure 1B The illustrated system may include a vehicle 112 and a vehicle communication bus (VCB) 122. The vehicle 112 may be the subject of diagnostics performed by the DCD 104. In other words, the DCD 104 may be configured to perform vehicle diagnostics related to the vehicle 112. An embodiment of the vehicle 112 and the VCB 122 is depicted below. The DCD 104 may be configured to communicate with the vehicle 112. For example, the DCD 104 may be configured to transmit vehicle data messages (VDMs) to the vehicle 112 and / or receive VDMs from the vehicle 112. Computing devices configured to transmit and / or receive VDMs from a vehicle are generally referred to as vehicle scan tools. Snap-on Corporation of Kenosha, Wisconsin, sells high-quality vehicle scan tools, such as the ZEUS™ Diagnostic and Information System Model EEMS342W and the ZEUS™ Diagnostic and Information System Model EEMS330W. Edge diagnostic and information system.

In other embodiments, receiving the matrix code may include the DCD 104, 200 receiving a matrix code generated by the processor 202 based on data contained in a content description received by the DCD 104, 200, the processor 202, and / or the network transceiver 204. The processor 202 may execute the CRPI 240 to generate the matrix code. In other embodiments, receiving the matrix code may include the CCD 108, 261 receiving a matrix code generated by the processor 263 based on data contained in a content description received by the CCD 108, 261, the processor 263, and / or the network transceiver 265. The processor 263 may execute the CRPI 287 to generate the matrix code. The matrix code may be encoded with a link (e.g., link 242) to the file 572.

[0160] Next, block 702 includes determining a condition indicating that the first computing device is unable to display the one or more files at at least a minimum quality level. The determination may be based at least in part on the content description.

[0161] In some embodiments, the first computing device is configured as a DCD, such as DCD 104, 200. In at least some of those embodiments, processor 202, 263 may execute CRPI 240 to determine that DCD 104, 200 is unable to display video files at at least a minimum video quality level by determining circumstances in which DCD 104, 200 is unable to display the one or more files at at least a minimum quality level. By way of example, the conditions determined may include: (1) the display 232 is not configured to display any video, (2) the file name of the video file has a file extension that is not supported by the processor 202, (3) the DCD 104, 200 does not include a CODEC for decoding the video file, (4) the media server 116 or server 560 transmits the video file at a bit rate that is too slow, such that the display 232 is unable to continuously display the video after initially displaying the video file, (5) the media server 116 or server 560 transmits the video file at a bit rate that is too fast, such that the one or more buffers configured to store portions of the video file in the memory 212 will fill to capacity and will not be able to store all received portions of the video file, (6) the strength of the communication signal to the DCD 104, 200 via the communication network 102 is below a threshold signal strength level, (7) a particular type of network connection is not available to the DCD 104, 200, and / or (8) the display 232 is unable to display the video file and diagnostic text simultaneously.

[0162] In other embodiments where the first computing device is configured as a DCD (such as DCD 104, 200), the processor 202, 263 may perform CRPI to determine that the DCD 104, 200 cannot traverse a network resource link (such as in Fig. 16C The situation of link 1653) shown in .

[0163] In some embodiments, the specific type of network connection may be a specific cellular air interface protocol or radio access technology. Examples of existing cellular air interface protocols or radio access technologies include AMPS, CDMA (e.g., 1xRTT), IDEN, TDMA, GSM, GPRS, EDGE, and MMDS, third generation (3G) cellular protocols (such as CDMA 2000 1xEV-DO or UMTS), fourth generation (4G) broadband radio access technologies (such as LTE, e.g., FDDLTE and TDDLTE), or WiMAX. As another example, the specific type of network connection may be a 2.4 GHz band, a 3.6 GHz band, a 4.9 GHz band, a 5 GHz band, or a 5.9 GHz band. Protocol connection.

[0164] The minimum video quality level can be defined using one or more characteristics. Examples of these characteristics are discussed in this paragraph and the following two paragraphs. In at least some embodiments, the minimum video quality level can be defined as a frame rate (e.g., the frequency with which video frames are displayed). The frame rate can, but does not have to be, defined in frames per second (FPS). As an example, the frame rate can be 24 FPS (e.g., high-definition (HD) video), 23.98 or 23.976 FPS (HD video with NTSC compatibility), 25 FPS (PAL, HD video), 29.97 FPS (NTSC, HD video), 30 FPS (HD video), 50 FPS (PAL, HD video), 59.94 FPS (HD video with NTSC compatibility), 60 FPS (HD video), or some other frame rate. NTSC refers to the National Television System Committee. PAL refers to Phase Alternating Line.

[0165] In at least some embodiments, the minimum video quality level can be the aspect ratio (i.e., the ratio of the width of a frame of video to the height of the frame). As an example, the aspect ratio can be 16:9, 1.78:1, 1.33:1, or some other aspect ratio.

[0166] In at least some embodiments, the minimum video quality level can be the resolution of the video. As an example, the resolution can be defined as the number of horizontal lines of vertical resolution, such as 1080p, where 1080 represents 1080 lines of vertical resolution and "p" represents progressive scan. Other example resolutions defined as the number of horizontal lines of vertical resolution include 240p, 360p, 480p, 720p, 1440p, 2160p, 3840p. In addition, the resolution of the video can be a ratio of pixels, such as 426x240, 640x360, 854x480, 1280x720, 1920x1080, 2560x1440, 3840x2160.

[0167] In other embodiments, the first computing device is configured as a CCD, such as CCD 108, 261. In at least some of those embodiments, the processor 202 may execute CRPI 240 to determine that the CCD 108, 261 is unable to display the one or more files at at least the minimum quality level includes the processor 202 determining that the CCD 108, 261 is unable to display the video files at at least the minimum video quality level. In those embodiments, the processor 202 may execute CRPI 240 to determine that the CCD 108, 261 is unable to display the video files at at least the minimum video quality level. By way of example, the conditions determined may include: (1) the display 283 is not configured to display any video, (2) the file name of the video file has a file extension that is not supported by the processor 263, (3) the CCD 108, 261 does not include a CODEC for decoding the video file, (4) the media server 116 or server 560 transmits the video file at a bit rate that is too slow, such that the display 283 is unable to continuously display the video after initially displaying the video file, (5) the media server 116 or server 560 transmits the video file at a bit rate that is too fast, such that the one or more buffers configured to store portions of the video file in the memory 271 will fill to capacity and will be unable to store all received portions of the video file, (6) the signal strength of the communication to the CCD 108, 261 via the communication network 102 is below a threshold signal strength level, (7) a particular type of network connection is not available to the CCD 108, 261, and / or (8) the display 283 is unable to display the video file and diagnostic text simultaneously.

[0168] As another example, a condition indicating that the first computing device is unable to display the video file at at least a minimum video quality level may be a condition where a communications network used by the first computing device is insufficient to transmit the video file for continuous display from the beginning of the video file to the end of the video file when playback of the video file begins at the first computing device. As yet another example, a condition indicating that the first computing device is unable to display the video file at at least a minimum video quality level may be a condition where a communications network used by the first computing device is insufficient to transmit a portion of the video file within a threshold time for continuous display of the video file from the beginning of the video file to the end of the video file after playback of the video file begins at the first computing device.

[0169] As an example, network conditions and / or transmission rates can be determined by transmitting communications and determining network conditions based on the time required to obtain a response to the communication. For example, a request for a matrix code is transmitted at time T1, and a response including the matrix code is received during time period T2 to T3. The transmission rate can be determined as the number of bytes of the received matrix code divided by the transmission time (T3 minus T2). The determined transmission rate can be used to determine the expected time length for downloading a video file using the same transmission rate. If the determined time length exceeds the playback time of the video file, the processor can determine that the video file cannot be displayed at least at the minimum video quality level. In some embodiments, determining that a network condition exists based on the expected time length for downloading a video file can be conditioned on the time length exceeding a threshold time amount (such as one minute or some other time amounts).

[0170] Next, block 703 includes outputting, by the processor 202, 263, a matrix code to the first display in response to determining the condition indicating that the first computing device is unable to display the one or more files at at least the minimum quality level.

The matrix code received at the network transceiver 204 may be stored in the memory 212 as the matrix code 244.

[0172] In other embodiments, the first display is a display at the CCD 108, 261 (e.g., display 283). In those embodiments, outputting the matrix code may include the processor 263 outputting the matrix code 291 to the display 283, or the processor 202 causing the network transceiver 204 to output the matrix code 244 over the communication network 102 for transmission to the network transceiver 265 of the CCD 108, 261. The matrix code received at the network transceiver 265 may be stored in the memory 271 as the matrix code 291.

[0173] Next, block 704 includes displaying the matrix code on the first display. In embodiments where the first display is a display at DCD 104, 200, display 232 may display matrix code 244. Displaying a matrix code, such as matrix code 244, may include displaying a representation of the matrix code on the display. Fig. 16CMatrix code 1650 is shown on display 232. Matrix code 1650 may be representative of matrix code 244. In other embodiments, the first display is a display at CCD 108, 261 (eg, display 283).

The server 106, the file server 114, or the media server 116 may determine the content sequence information and provide the content sequence information to the DCD 104 via the communication network 102.

[0176] As an example, the content order information can be based on the popularity of the content associated with one of the multiple content descriptions. The following examples in this paragraph relate to an embodiment in which the content description includes a video file. For example, the content order information can be based on the ratings of the multiple videos. As another example, the content order information can be based on the ranking of the multiple videos from the highest frequency of repairing vehicles to the lowest frequency of repairing vehicles. As another example, the content order information can be based on the time length of the multiple videos (e.g., the order of the videos from the shortest display time to the longest display time). In addition, the content order information can be based on two or more factors described above for determining the order of videos.
