Description

Technical Field

[0001] This invention relates to the field of remote control document playback technology, and in particular to a method, system and medium for remote control document playback. Background Technology

[0002] As LED display technology matures, more and more LED displays are entering our lives, and their applications are becoming increasingly diverse. For example, some scenarios require more than just displaying static images, GIFs, or videos; they also need to be integrated into factory workshops, government announcements, or restaurant guides. These scenarios require remotely projecting edited DOC documents, PPT documents, or XLS spreadsheets onto terminal devices via the internet. After successful projection, the document content should be able to play quickly on the LED display, supporting both automatic and remote page turning. However, document preview solutions need to consider cost, integration with playback control, and performance consumption. Therefore, a solution is needed to address the issues described above. Summary of the Invention

[0003] The main objective of this invention is to propose a method, system, and medium for remotely controlling document playback. The aim is to achieve remote control and document processing of document-based advertisements by building a document processing server, converting document files (such as PPT, PDF, Word, etc.) into multiple images for playback, achieving low cost, low performance consumption, and support for integrated control playback, simplifying playback logic.

[0004] To achieve the above objectives, the present invention provides a method for remotely controlling document playback, the method comprising the following steps:

[0005] Step S10: After receiving the document file of the pushed advertisement, the advertising management system parses the document file and converts it into a PDF image.

[0006] Step S20: Read the PDF images, obtain the page number of the PDF images, and save each page of the PDF image as two sets of images with different resolutions. One set of low-resolution images is used to preview the document material, and the other set of high-resolution images is used for advertising programs.

[0007] Step S30: Assemble the low-resolution images into an image with specified width, height and size;

[0008] Step S40: Review the assembled images and synchronize the review results to the material list viewing area;

[0009] Step S50: After successful review, the other set of images at different resolutions is pushed to the terminal device for playback via the IoT server.

[0010] A further technical solution of the present invention is that step S50 includes:

[0011] After successful review, the HTTPS download address, image size, image MD5 hash, and corresponding page number of the image are packaged into encrypted advertising program data and then pushed to the terminal device for playback.

[0012] A further technical solution of the present invention is that, after step S50, it further includes:

[0013] Step S501: The terminal device parses and verifies the advertising program data to determine whether it is a correct and legal protocol.

[0014] Step S502: If the agreement is correct and valid, then the legality of the advertising resource download list is verified.

[0015] Step S503: If the list of advertising resources for download is valid, then determine whether the download resource is a document resource;

[0016] Step S504: If the downloaded resource is a document resource, record the corresponding page number for each image, draw the background at the resolution of the advertising area, draw the document image onto the background page, and play it according to the set mode.

[0017] A further technical solution of the present invention is that step S502 includes:

[0018] Step S5021: Determine if the download address is downloadable;

[0019] Step S5022: If possible, compare the size and MD5 of the downloaded file with the information pushed by the advertising management system. If both are valid, the advertising resource download list is deemed legitimate.

[0020] A further technical solution of the present invention is that, after step S501, it further includes:

[0021] If the advertising program data is not a correct and valid protocol, an error is returned, and the data is judged as invalid advertising data.

[0022] A further technical solution of the present invention is that, after step S502, it further includes:

[0023] If the list of ad resources for download is invalid, an error will be returned, indicating that the ad data is invalid.

[0024] A further technical solution of the present invention is that, after step S503, it further includes:

[0025] If it is not a document resource, then proceed with the corresponding ad type logic.

[0026] To achieve the above objectives, the present invention also proposes a remote control document playback system, the system comprising a memory, a processor, and a remote control document playback program stored on the processor, wherein the remote control document playback program is executed by the processor to perform the steps of the method described above.

[0027] To achieve the above objectives, the present invention also proposes a computer-readable storage medium storing a remote control document playback program, which, when run by a processor, executes the steps of the method described above.

[0028] The beneficial effects of the remote control document playback method, system, and medium of this invention are:

[0029] This invention, through the above technical solution, allows the advertising management system to parse the document file of the pushed advertisement after receiving it, converting it into PDF images; reading the PDF images, obtaining the page number of the PDF images, and saving each page of PDF images as two sets of images with different resolutions. One set of low-resolution images is used to preview the document material, and the other set of high-resolution images is used for the placement of the advertisement program; the low-resolution images are then assembled into an image with specified width, height, and size; the assembled image is reviewed, and the review result is synchronized to the material list for viewing; after successful review, the other set of high-resolution images is pushed to the terminal device for playback via an IoT server. By building a document processing server, remote control and document processing of document-based advertisements are achieved, converting document files (such as PPT, PDF, Word, etc.) into multiple images for playback, achieving the goals of low cost, low performance consumption, support for integrated control playback, and simplified playback logic.

[0034] Figure 4 This is a system architecture diagram of the remote control document playback system of the present invention.

[0035] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention proposes a method for remotely controlling document playback. The technical solution adopted by this invention mainly involves building a document processing server to achieve remote control and document processing of document-type advertisements. The document files (such as PPT, PDF, Word, etc.) are converted into multiple images for playback, achieving low cost, low performance consumption, and support for integrated control playback, simplifying the playback logic.

[0038] The hardware architecture involved in the remote control document playback method of the present invention will be introduced first below.

[0039] like Figure 1 As shown, the hardware architecture involved in the remote control document playback method of the present invention includes a back-end management system (i.e., an advertising management system), an Internet of Things server, and terminal devices.

[0040] The process of displaying document advertisements on the terminal device screen is as follows: the terminal device is connected and bound to the IoT server through MQTT or other IoT communication protocols. Through a long connection, the device can be online in real time and push advertisements and receive push results with low latency.

[0041] This process only handles network communication logic, and is decoupled from the advertising system, so they do not affect each other. The backend management system is an advertising management system that can interface with and adapt to IoT servers. After logging into the backend management system, users can add uploaded document files to the advertising program and select devices for push. The backend management system then combines the advertising program data with the unique characteristics of the devices and pushes it to the IoT platform to achieve remote delivery.

[0042] The solution of this invention enables remote delivery of document advertisements, ensuring secure transmission and a certain degree of security for the content page. It guarantees that the advertisements will play normally on the device terminal display screen and reduces disputes over illegal advertisements.

[0043] like Figure 2 As shown, the first embodiment of the remote control document playback method of the present invention includes the following steps:

[0044] In step S10, after receiving the document file of the pushed advertisement, the advertising management system parses the document file and converts it into a PDF image.

[0045] After logging into the system, users can select the document file for which they want to receive advertisements and upload it to the ad management system. Upon detecting the new document file, the ad management system will asynchronously parse it, first converting it to PDF, and then converting it into a PDF image. It should be noted that in this embodiment, after uploading the document file, it will display a "pending review" status.

[0046] This embodiment converts the document into multiple PDF images for playback, offering strong compatibility, avoiding formatting errors, and ensuring a consistent image display. Furthermore, the image format is difficult to edit directly, which helps prevent unauthorized modification and simplifies the playback logic.

[0047] Step S20: Read the PDF images, obtain the page number of the PDF images, and save each page of the PDF image as two sets of images with different resolutions. One set of low-resolution images is used to preview the document materials, and the other set of high-resolution images is used for advertising programs.

[0048] Step S30: Assemble the low-resolution images into an image of a specified height and size.

[0049] After generating the PDF image, the advertising management system will assemble the low-resolution image into a picture with specified width, height, and size by arranging it from left to right and top to bottom according to its height. This is done to reduce the number of AI review requests, increase efficiency, and save costs. It is also because some AI content review images have limitations, such as resolution and file size.

[0050] Step S40: Review the assembled images and synchronize the review results to the material list viewing area.

[0051] Step S50: After successful review, another set of images with different resolutions is pushed to the terminal device for playback via the IoT server.

[0052] Step S50 specifically includes:

[0053] After successful review, the HTTPS download address, image size, image MD5 hash, and corresponding page number of the image are packaged into encrypted advertising program data and then pushed to the terminal device for playback.

[0054] In this embodiment, only documents that pass review are allowed to be delivered, ensuring display security and reducing disputes. After delivery, each image generated from the document is encapsulated, including its corresponding HTTPS download address, image size, image MD5 hash, and corresponding page number, all uniformly packaged into encrypted program data. This aims to prevent data tampering and hijacking during the download process, ensuring secure remote delivery. Documents that fail review cannot be delivered.

[0055] Furthermore, based on Figure 2 The first embodiment shown illustrates a second embodiment of the remote control document playback method of the present invention, as follows: Figure 3 As shown, in this embodiment, after step S50, the following is also included:

[0056] Step S501: The terminal device parses and verifies the advertising program data to determine whether it is a correct and legal protocol.

[0057] Step S502: If the agreement is correct and valid, then the legality of the advertising resource download list is verified.

[0058] Step S503: If the list of advertising resources for download is valid, then determine whether the downloaded resource is a document resource.

[0059] Step S504: If the downloaded resource is a document resource, record the corresponding page number for each image, draw the background at the resolution of the advertising area, draw the document image onto the background page, and play it according to the set mode.

[0060] Specifically, step S502 includes:

[0061] Step S5021: Determine if the download address is downloadable;

[0062] In step S5022, if the download is successful, the file size and MD5 hash of the downloaded file are compared with the information pushed by the advertising management system. If both are valid, the advertising resource download list is deemed legitimate.

[0063] In this implementation, during the document playback process on the terminal device, the IoT server pushes advertising data to the terminal device. The terminal device first needs to parse and verify the advertising program data to determine whether the format is correct and legal (the communication protocol is used internally and is not publicly available). If correct, the legality of the advertising resource download list is verified. The judgment logic is to compare the actually downloaded file with the data pushed by the advertisement to ensure file uniqueness, reduce the problem of delivery errors caused by tampering and hijacking, and ensure file integrity. Downloading files via HTTPS can achieve breakpoint resumption. When the network environment is poor or large files are downloaded, the reliability and efficiency of transmission are improved, saving time and bandwidth. If the downloaded resource is a document, each image records its corresponding page number, and the background is drawn at the ad area resolution. The document image is then drawn onto the background page. According to the set mode, playback can be scheduled at specified intervals in page order, or manually controlled via remote control. After large documents are converted into multiple images, lazy loading can be customized as needed, reducing memory consumption. This solution is easy for the program to control, requiring no pre-installed document preview software, reducing performance overhead and disputes over commercial licensing. It doesn't rely on specialized software, and the server-side image parsing simplifies the playback logic, resulting in faster playback and rendering. Parsing is handled by a high-configuration server, requiring no device consumption, and playback can be controlled automatically. It can even be combined with other material types, such as static images and videos, and dynamic effects combined with images are also supported. For images processed from documents, the server is responsible for any issues. Terminal networks are unstable and upgrades may be difficult; server-side document processing reduces the overhead of terminal device upgrades. Only a server update is needed to improve document delivery across the entire system.

[0064] In this embodiment, the method further includes the following after step S501:

[0065] If the advertising program data is not a correct and valid protocol, an error is returned, and the data is judged as invalid advertising data.

[0066] Step S502 is followed by:

[0067] If the list of ad resources for download is invalid, an error will be returned, indicating that the ad data is invalid.

[0068] Step S503 is followed by:

[0069] If it is not a document resource, then proceed with the corresponding ad type logic.

[0070] The beneficial effects of the remote control document playback method of the present invention are:

[0071] This invention, through the above technical solution, allows the advertising management system to parse the document file of the pushed advertisement after receiving it, converting it into PDF images; reading the PDF images, obtaining the page number of the PDF images, and saving each page of PDF images as two sets of images with different resolutions. One set of low-resolution images is used to preview the document material, and the other set of high-resolution images is used for the placement of the advertisement program; the low-resolution images are then assembled into an image with specified width, height, and size; the assembled image is reviewed, and the review result is synchronized to the material list for viewing; after successful review, the other set of high-resolution images is pushed to the terminal device for playback via an IoT server. By building a document processing server, remote control and document processing of document-based advertisements are achieved, converting document files (such as PPT, PDF, Word, etc.) into multiple images for playback, achieving the goals of low cost, low performance consumption, support for integrated control playback, and simplified playback logic.

[0072] To achieve the above objectives, the present invention also proposes a remote control document playback system, such as... Figure 4 As shown, the system includes a processor 1001, a CPU, a network interface 1004, a user interface 1003, a memory 1005, a communication bus 1002, and a remote control document playback program stored on the processor. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard. Optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0073] Those skilled in the art will understand that Figure 4 The system structure shown does not constitute a limitation on the system and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0074] like Figure 4 As shown, the memory 1005, which serves as a computer storage medium, may include an operating device, a network communication module, a user interface module, and a remote control document playback program.

[0075] exist Figure 4In the system shown, network interface 1004 is mainly used to connect to the network server and communicate with the network server; user interface 1003 is mainly used to interact with the user terminal and receive user input commands; and processor 1001 can be used to call the remote control document playback program stored in memory 1005.
